Organism, Community And Ecosystem Approaches To Study Ecology

Organism, Community And Ecosystem Approaches To Study Ecology
1.) When taking the organism, population, community and ecosystem approaches to study ecology one needs consider that there are levels that layout
the specific details of what each approach is. For organism approach, the processes look at the way an individual live in an environment and how this
individual behaves and adaption within its surrounding. The population approach concerns over a group of organisms, the number of female and male,
the differences within organisms, the similarity that they share, and their genetic makeup within a whole population. The processes and structures to
understand the community deal with understanding of the diversity and different groups of organisms living in the same place. The ecosystem approach
looks at the overall chemical reaction which is the transfer of energy and matter to make life possible. The processes occur in the atmosphere, aquatic,
and on land.
2.) In the Northern Hemisphere, many species of birds fly south during the autumn months because proximate: shorter photoperiods and less abundant
food. Birds fly south in search for their alternative food because during the harsh winter their food resources go down. Ultimate: their fitness increases

Water resists flow and the movement of organisms, which makes it hard for organisms with denser bones to move. Physical structures such as bones
and some proteins are dense and most likely make organisms to sink. Through adaptations, features for aquatic organisms reduce their physical density.
For example as Ricklefs mentions many fish species have a gas–filled swim bladder whose size can be adjusted to make their bodies equal to the
surrounding water. Small marine creatures have long filamentous appendages that take advantage of the viscosity and also prevent sinking. Adaptations
of aquatic organisms have make water as an easy way to move around in the

My Personal Statement Of Ecology
For me to fall in love with science, and ecology in particular, has been a lifelong process. I was lucky to have experienced an early discovery of the
joys and nuances of nature and this was supported throughout my youth and adulthood by teachers, peers, and most importantly, my family. My first
memory, of seeing light filtering through swaying trees above me, is indicative of the beauty and tranquility that nature has provided me throughout my
life. Although I have always had an innate respect and enjoyment of the environment, this feeling was amplified every time i would visit my family in
Valparaiso, Zacatecas, Mexico. These frequent trips to a pristine environment were what ultimately changed my perspective on the world, my personal
values, and led me to pursue an education in ecology.

Although they had never studied it in universities, they knew more about their land and its conservation than I ever could. They were aware of
the common names of every species, of how to grow what they needed, how to pollinate and take care of the soil, and how to raise and maintain
animals. My family knew how to live off of the land while tending to it for future generations. My mom and her siblings were able to turn the soil
to maintain maximum growth and could grow livestock to use the resources provided by them. They know which plants are medicinal and
beneficial, as well as which ones can be deadly. These concepts, of being able to conserve the environment, are what I focus on learning now. When
I apply the concepts I learn in my biology classes, such as on a recent restoration project in Baja California, I am reminded of what my family taught
me to do from a young age. Due to my experience of the beauty and grandeur of Valparaiso, Mexico, it feels only natural for me to keep pushing
towards the conservation and restoration of places like

The Financial Success Of A Company 's Social And Economic...
The biggest opposition to the protection of these wilderness areas is logging companies, who profit off clear cutting timber as quickly and efficiently
as possible. These companies then sell off the deforested land and move their operations elsewhere. Clear cutting forests can have some benefits in
specific instances, such as preventing the spread of disease or saving millions of dollars in Wildland firefighting costs ("Biodiversity and the Cost of
Clear Cutting" – Musicians for Forests, 2015). Unfortunately, these timber clear cutting operations come at a cost to taxpayers, local ecosystems, and to
loggers themselves. I can acknowledge that the financial success of a company has social and economic benefits within human society. However, I
believe that allowing a company to profit at the expense of our ecological environment, degrading the very foundations of terrestrial life, is antithetical
to ethical behavior and human prosperity.
The following section outlines the economic, ecological, and social costs of clear–cut logging in the Northern United States. I believe that the costs far
outweigh any good that politicians, lobbyists, or logging companies could argue come from aggressive clear–cut logging operations. In 1993 logging
on public lands in the northern Rockies (Region One) by the United States Forest Service cost the government between $100 million and $200 million
more than the amount received for the sale of the timber (Bass, 1996). Compare this with the $2.5

Ecosphere Vs. Commoner : The Ecosphere World And The...
Ecosphere versus Technosphere Commoner believes humans live in two worlds: the ecosphere world and the technosphere world. Ecosphere is
referred to as the physical, biological, and chemical processes that occur naturally, such as storms, droughts, and floods. The technosphere world is a
man–made creation that helps us to survive within the ecosphere. These creations include technology, homes, factories, laboratories, music, art, etc.
According to Commoner (1992), we accept responsibility for events in our own world, but not for what occurs in the natural one (pg. 3). Human beings
need to understand the interaction between these two worlds and the threats they impose on each other.
Four Laws of Ecology The first law of ecology states, "Everything is connected to everything else". Everything within the ecosystem has a
responsibility to maintain the balance of the ecosystem in order for living things to survive. The ecosphere is a habitat to numerous of living
organisms. It is very complex and interconnected in many ways. Commoner explains how the ecosphere produces organic waste that nourishes
microorganisms and aquatic plants. The plants are able to produce oxygen into the environment by photosynthesis. Within the technosphere, the first
law of ecology pertains to it differently. A variety of man–made objects have relationships to there surroundings. It is more harmful to the environment
than beneficial. In Making Peace with the Planet, Commoner used an example of a car

Review of Wolves and the Ecology of Fear: Can Predation...
In this article, authors William Ripple and Robert Beschta focus on the issue of predation and the way it affects biodiversity and otherwise alters
ecosystems. While many other studies have stressed the lethal effects of predation by carnivores, the authors of this study have chosen to focus on how
nonlethal outcomes of predation affect the structure and function of ecosystems. The authors give two main objectives to their study: first to provide a
short synthesis of the potential ecosystem responses to predation risk in a three–level trophic cascade involving large carnivores, hoofed animals, and
vegetation; and secondly to present research that centers on wolves, elk, and woody browse species in the northern area of Yellowstone National...

For example, their concept indicates that prey species will alter their foraging habits to the features of the terrain in order to avoid areas with a high
risk of predation. Predation risk in a changing environment is also focused on by the authors. There are many environmental variables that may
influence the degree of predation risk such as weather, wildfires, and other conditions that influence ungulates' access to vegetation. Finally, the authors
focus on ecosystem responses to trophic cascades–primarily on riparian functions and on beaver and bird populations. They also inform us that wolves
may represent an indirect control on beaver populations as well as cause ungulates to avoid some riparian areas–therefore reducing herbivory on
wooden browse species. The authors eventually discuss the Yellowstone experiment and share their research results. They focus on the northern winter
range which is a large mountain terrain that mostly occurs within the northeastern area of Yellowstone National Park. Here, the authors took into
consideration annual precipitation and even the average depth of snowpacks. After looking to historical data for the northern range of Yellowstone,
Ripple and Beschta evaluated recruitment on aspen and cottonwood over the last two centuries and found that the extirpation of wolves allowed elk to
browse unimpeded during winter months. After going over data from Yellowstone after wolf

Environmental Effects Of Invasive Species
The dangers to our world today have resulted in serious problems. In this regard, our ecosystems are threatened by invasive species. These species
have concluded into significant habitat destruction. For example, Phragmites Australis, also known as the common reed is a major invasive species
around the world. These originated from Europe and are now found all over the United States. They have been around for two centuries and are still
around today. Common reeds are found to be native and nonnative. This species is a part of the grass family, usually hollow and green with yellow
knots. They are around 6–13 feet tall and are found in wetlands and ditches. There are three lineages created of the common reed, one, the North
American lineage. Invasive species have negative, detrimental effects on the ecosystems and environments.
In the article, Phragmites, Invasions Harm Riparian Property Values, studies are showing that the common reed is a harmful plant. For example,
they block parts of the sidewalks and restrict the access to water, such as on lakes or ponds. For instance, residents pay excessive amounts of money
to live on lakes, that offer all the water activities and a pretty view in general, but when the invasive species intrude they block the views and access
to the water. In result, it ends up leaving these places unable to manage. The other effect they leave is with sidewalks. They usually spread from
ditches to all over the sidewalks and such. Therefore, they

Community Ecology Lab
Ecosystem is made up of all populations living together and the physical factors with which they interact with their environment. The ecosystem gets its
energy from the only source, the sun, which make it important. The sun plays significant roles in ecosystem functioning of photosynthesis. In this lab,
we will focus mostly on population and community ecology. Population ecology is a group of organisms of the same species living in the same place
at the same time. Factors that affect the number of individuals living in a habitat are the population growth rate, size, birth and death rates. Community
ecology focuses on the interactions between organisms as to preys and predators. These will lead to the causes that affect animals population; including

Sargeant Reynolds. We explored and observed the different types of plants and animals in the forest that make up theecosystem. We found a diversity
of plants and animals: millipede (apheloria virginiensis), Darkling beetle, pine cone, northern pin, holly tree, and turkey tail fungus. (trametes
versicolor) Records were kept of the presence and absence of different species. Not all of the species of interest were found during the observing time.
The time and day that we did the observation is also the cause of the absences of certain animals.
Purpose:
The purpose of this lab is to analyse and explain how the ecosystem work in our community. How birth and death rates have impact on the living
population. If the rate of the bug–eating bird grow larger then the population of the insects will decline. Discussion:
Food web is a network of food chains with a number of feeding connections amongst different organism of a biotic community. The food chain starts
from decayed plants and animals to the micro–organisms and then to detritus feeding organism and to other predator. There are three trophic levels.
Starting with producers, consumers, and decomposers. Plants such as holly leaves and pine trees are types of producer that make their own food
through photosynthesis and do not depend on any other organism for nutrition. Millipedes and darkling beetles are in the next trophic level,

The Complex Processes Of Urban Development
The complex processes of urbanisation overarches and entails a set of social, cultural, economic, political, environmental and technological functions
that result in sprawl and densities, proportional to core size and settlement. Further implicating the extensive use of natural resources from fringes and
rural spheres within city limits to be consumed and then later in turn converted into waste. Urban ecosystems are therefore, complex multifaceted
systems that require a burdensome amount of natural resources input and negotiations for their adequate development. In urban discourse, the lack of
interdisciplinary and trans–disciplinary interest partly due to an absence of tools to which all disciplines can use to further incorporate ecological
theories to assessment and planning of urban centers. All these connections have been made and academics have divided the complex concept into
biophysical processes and socioeconomic processes when examining cities in case studies. The urban ecology theory and a closely related concept of
urban metabolism can explain the technical aspects of urban density and growth but human influences are not accounted for in the assessment.
However, human scholarship is a key component that shapes the metabolic processes in urban ecologies and in turn alters the initial footprint.
By examining the historical context of urban ecology, the early stages and latter results of the urban ecology theory being transformed from a
multidisciplinary concept into

The Valuation And Commodification Of Ecosystem Services
The Valuation and commodification of Ecosystem Services
Ecosystems in our world act as vital and fundamental sections to maintain health, living, well–being and survival of human beings and other creatures
(Robert Costanza et al, 1997; Millennium Ecosystem Assessment (MEA), 2005; TEEB Foundations, 2010; TEEB Synthesis, 2010). They provide
different kinds of service, such as production of goods, life support processes, and life–fulfilling conditions (Gretchen C. ,2000). Ecosystem
significantly contributes to both economic and non–economic value of our planet, but when compared to market efficiency, it seems to be paid less
attention when involved in decision making. In the majority of the ongoing projects that have numerous debates on, it seems common for people
put a price tag on ecosystem services and evaluate them by means of commodification. When the immediate or intuitionistic benefits fail to be
derived, it is less likely for ecosystems to be protected or reserved. Therefore, the importance of ecosystem services is often poorly appreciated and
only to be seen when facing severe problems. People are less likely to come up with solutions to protect the ecosystems of their own will than to make
a better trade to exchange ecosystem services for money. Also, it is quite often to fail to define the difference between "valuation" and "privatisation",
considering ecosystem services more of tradable products than a part of nature system. It is often overlooked that the market

Ecology and Biology: An Overview
Ecology and biology: An overview Ecology has been defined as "the branch of biological sciences dealing with the interactions between living beings
and their environment," versus the study of the morphology or behavior of species in isolation (Nahle 1997). Another definition of ecology is that it is
"the scientific study of interactions of organisms with one another and with the physical and chemical environment" (What is ecology, 2012, Science
Education). Ecology has become associated with the study of specifically environmentally–related problems such as pollution, global warming, and the
ways in which the human species has had a specific (often negative) impact upon the earth. The goal of many research studies in ecology today
revolves around finding ways to minimize the negative impact of specific behaviors on the planet and to optimize the use of natural resources. The
study of ecology is also critically linked to a more full understanding of evolutionary biology both human evolution and the evolution of all species
upon the earth. "All evolutionary change takes place in response to ecological interactions that operate on the population, community, ecosystem, biome
and biosphere levels" (What is ecology, 2012, Science Education). The development of one species affects other species. Patterns of species
development likewise affect the planet, as environmental changes affect us. The discipline of ecology divides the ecosystem, or the entirety of living
beings, into

The fish and crickets are still moving. The plants look a bit unhealthy but otherwise fine. The flowers are beginning to bloom. Day 4 5/29/07 The
water is a medium dark color. The fish is still moving. The plants looked chewed up. Day 5 5/30/07 The water has become dark yellow. I can?t tell
if the fish is alive. The crickets are still moving. Day 6 6/4/07 The water is a dark yellow. The plants are growing mold. 1 cricket is still alive when
2 crickets are dead and the fish is still alive. Day 7 6/6/07 The water is a Chinese tea color. The fish seems lively. The cricket is the last survivor of
the terrestrial environment. There is much mold on the plant yet there seems to be growth. Day 8 6/7/07 The water is still a Chinese tea color.
Many of the features of yesterday are prevalent. More mold growth has occurred but other then that the environment is the same. Day 9 6/8/07 The
water is still a Chinese tea color. More mold (Or could it be spider webs?) has dominated the plant. 1 cricket is a survivor and the fish thrives.

government (As invincible and as strong as some may seem) have done the same. Of course over the thousands of thousands of years of human history
has existed the urge to learn more about themselves and the world around them.

Ecology Terrarium Project: Study Of Ecosystem
Ecology Terrarium Project–Essay
Ecology is the study of the interaction of living things between themselves, as well as their surrounding in their environment. It is important to study
ecology so we can understand how the world around us works. The major components of an ecosystem are abiotic factors and biotic factors. Abiotic
factors include rocks, the temperature of the ecosystem, the soil, sand, and the PH of the water. The Biotic factors are all the the autotrophs and
animals that live in the ecosystem. A biosphere contains all of the ecological levels, and the only biosphere we know of is our Earth. In our Earth, the
biosphere contain all ecological levels, but also the atmosphere. Our model shows a miniature biosphere because it contains both abiotic and biotic
factors, as well as the moisture from the water input, that represents the atmosphere of the Earth.
Inside our terrarium, there is both abiotic and biotic factors, as well as gasses such as carbon dioxide, oxygen, water vapor, and nitrogen. The only
factors that can enter and exit the glass jar is sunlight, because it can pass through the glass, but everything else is concealed inside the jar, unless we

The water cycle is the process in which water changes states of matter, from a solid, to a liquid, to a gas, and the cycle continues. You can see this
cycle in our terrarium. The condensation on the glass is the visual representation of the gas for of the liquid water that we sprayed into the terrarium,
that evaporated. Unless it is cold enough, the water will freeze into ice. Photosynthesis is the process in which plants take sunlight, carbon dioxide, and
water, and transform them into glucose, sugar, and oxygen. The plant breaths when it takes in sunlight, carbon dioxide, and water, but when put in the
dark, or there is no water or carbon dioxide left inside the terrarium, then the plant will die and

Environmental Ethics And Its Impact On The Environment
ntroduction and Thesis
Environmental ethics is a branch of philosophy that examines human relationships to, and the ways they interact with, the environment. When it was
noticed, that the increasing world population was negatively impacting the environment, as well as the use of pesticides, technology and
industrialization, environmental ethics emerged as a field of study. Environmental ethics takes into consideration the value and moral standing of the
environment and its non–human entities. It focuses on the value humans place on nature and defines their moral and ethical obligations to it, and there
place in it.
Moral standing is when value is placed on certain things and this value is used to determine if something is morally acceptable or not. Humans have
moral standing when they do something for the individuals sake and not for their or someone else ' benefit. There are different ethical approaches that
focus on the morality (right or wrong) of human behavior and their impact on the environment, and this paper covers five that will argue for the best
suited to resolve environmental issues. This paper argues that Ecocentric Ethics is the best approach to environmental ethics.
Explanation of Views
This section examines the theories of Immanuel Kant, Tom Regan, Peter Singer, Paul Taylor, Aldo Leopold, and Arne Naess. These philosophers have
different approaches to environmental ethics, and this paper discusses what constitutes moral standing, who or what deserves it,

Coastal Ecosystem Response Paper
Coastal marine ecosystems are a very important part of the coastal economy as well as the natural ecology. Not only do coastal systems provide
socioeconomic benefits such as tourism and aesthetics, but also several ecosystem services. The ecosystem services provided by coast environments
include coastal erosion, storm protection, recreational or commercial fishing, carbon sequestration and filtration (Wingard and Lorenz, 2014).
Unfortunately, these services have been impacted by pressures such as altered flow of freshwater runoff, sea level rise (which in turn also increases the
frequency and intensity of storms) and man–made channels (Wingard and Lorenz, 2014). Another major factor that has impacted and deteriorated
many coastal areas is urbanization... Show more content on Helpwriting.net ...
According to Cendrero and Fischer (1997), each indicator receives a value between 0 and 1 as well as a weighing factor. The weight for each
indicator is multiplied to the value of each indicator and then these numbers are combine to get a total score. Cendrero and Fischer (1997) then
developed a "conservation–development diagram" that would map the values from the total combination and could determine areas in need of
conservation as well as areas that could potentially developed. On the other hand, Barbosa de Araujo and da Costa (2008) developed a system where
sixty parameters are taken into consideration where natural parameters where given a values of 1, 2 or 3 and socioeconomic parameters were given
qualitative values of either "+" or "–." These were then added and assed on a A–D grading scale. Alternatively, Marshall et al. (2014) developed a
system where each indicators was given a score of 1 (for poor), 2 (for fair) or 3 (for good). These were then added together and compared. A score
between 9 and 14 designated poor condition of the beach. Between 15 and 20 designated fair condition and between 21 and 26 designated good

Urbanized areas also modify microclimates and air quality by altering the nature of the land surface and generating heat (Oke, 1987). Although
ecological impacts of urban development often seem to be local, urbanization also causes environmental changes at larger scales. Today's cities are
sustained by a socioeconomic infrastructure that operates on global scales; the ecologically productive area required to support an urban area can be
100 to 300 times larger than the urban region (Rees & Wackernagel, 1994). A new cooperative relationship between science, business and policy is
needed to gather all the information needed and to find a solution that benefits all of society. The study of urban ecology ultimately involves studying
how to integrate this new interdisciplinary knowledge about urban ecosystems into policymaking processes––to improve interactions between
policymakers and scientists so as to help society achieve more sustainable existence. Today, the scientific and political communities lack the effective
two–way communication and trust that they need to address urban ecological problems. Although science can help society formulate a range of options
to achieve societal goals, it cannot make value judgments. In addition, scientists often cannot deliver definitive answers to questions posed by
policymakers. To be able to find solutions to the larger issues

INTRODUCTION
Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is "The degree of variation
of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of
climate." (Rutherford) Ecosystem is on the other hand, " community and its abiotic environment"( Rutherford). Biodiversity exists in every ecosystem,
weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions
needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and ... Show more content on

Essay about Understanding Ecosystems in Today's Society
Introduction:
An ecosystem is all the organisms in a given area as well as the abiotic factors with which they interact; one or more communities and the physical
environment around them (Campbell, 2012, G–11). Our aim is to observe how these factors interact with each other and give a record of our
observations in our particular ecosystem. By observing these interactions we gain an appreciation of the diversity and complex nature of ecosystems.
Through observing our environment we can make predictions of the feeding relationships that shape the ecosystem. By observing the plant life in an
ecosystem we can predict the following heterotroph factors, as autotrophs are the providers of all energy. Through understanding ecosystems we see that

Place chopsticks, or whatever stick objects you have, in the group in a 1x1m2 quadrat with string wrapped around the sticks.
Count the number of plant species in the quadrat sectioning them off into five different groups, trees, shrubs, herbs, grass and moss.
Trees being one singular wood growth while shrubs have multiple stems coming from the ground. Grass is blade like leaves. Herbs are usually soft
grass like plants with more leaves then blades. Add these species into your table 1.
Once you've completed this extend your quadrat to 1x2m2. Add any additional species, making sure not to count species you've already counted in the

allows for better conservation practices. Organismal biology will allow me to have in depth knowledge of species behavior, physiology, and
evolutionary history, which is essential information when making management and conservation plans for specific species. Understanding the genetic
structure and background, and evolutionary history of species and populations allows for a better understanding of patterns of dispersal, and allows
predictions to be made about how species will react to future environmental threats such as climate change.

Understanding how organisms interact with each other and their ecosystems is an important aspect of conservation. Ecology will include the ecology
of a diversity of species and environments such as wildlife ecology and freshwater ecology. An understanding of ecology allows for better management
of human impacts on the environment. Ecology also provides necessary conservation tools such as ways to model and organize ecosystems, which is
necessary for areas such as wildlife management. Ecology will allow me to understand the dispersal, migration, and population dynamics of species;
having an understanding of ecology is essential when working to create solutions for environmental problems that species face, for example, in
stabilizing populations of endangered

Creating A Sustainable Terrestrial Ecosystem Within A...
Mesocosm Lab
Exploration
Research Question:
With the plants chosen, is it possible to create a sustainable terrestrial ecosystem within a sealed glass jar?
Background Information
The purpose of this experiment is to become familiar with how an ecosystem works, and discover the most sustainable kind of ecosystem. Based on
knowing how an ecosystem works, predictions have been made that state if a terrestrial mesocosm is sealed for four weeks with plants inside, it can
continue to live and thrive sealed from the outside environment because the plants will gain their moisture from the humidity left in the sealed jar. The
plants will use photosynthesis and carbon dioxide in order to transform the carbon dioxide into oxygen and water.
A mesocosm is any outdoors experimental system that examines the natural environment that is brought under controlled conditions. It is used to
model a larger ecosystem. (Oxford Journals) Mesocosms help scientists as they allow a more accurate prediction of previously unpredictable events.
(What is a Mesocosm) Mesocosms give scientists the opportunity to investigate the reaction of organisms to environmental change and have been used
in experimental ecology since the early 20th century. They have been used for almost over a 100 years, but just recently became significant as a way
of investigating certain ecological ideas. Mesocosms became more significant due to the study of climate change, since the late 90s. Through
mesocosms, scientists are

Alaska Glacial Retreat And Acidification Impacts On...
AGLACIER: Alaska GLacial retreat & ACidification Impacts on Ecosystem Resilience
The EPSCoR Overarching Question is: How can we understand regime shifts and tipping points in large–scale ecosystems in Alaska. The theme we
will address is: Coastal margins and marine living resources.
Overarching Goal: This proposed EPSCoR will focus on the impact of glacial melt on the physics and chemistry of the marine environment, and their
consequences for the intertidal and coastal biological communities.
Objectives:
1)Build on historical ecological data that describes the physical, biological, and chemical variability of Kachemak Bay, a subarctic biodiversity hot spot.
2)Determine the mechanisms that relate the present and anticipated future variability in glacial dynamics to shifts in coastal ecosystem structure and
function using laboratory and field experimentation, observations, and modeling.
Question:
How is variability in current and future glacial input to the marine environment influencing the structure and function of coastal marine ecosystems via
changes to the physical and chemical environment (i.e., temperature, salinity, stratification, turbidity, pH and the carbonate saturation state)?
Intellectual merit:
Healthy coastal marine ecosystems are critically important to America's ecology, economy, and standard of living. While Alaska contains nearly half of
the nation's coastline, we have little understanding of how future climate variability will impact ecological

Advanced Ecology Midterm (1) Why is scale important in ecology?
Ecology is the study of the distribution and abundance of organisms, their interactions between each other and their environment, and the structure and
function of ecosystems. To this end, the scale (spatial, functional, temporal, organizational, etc.) at which we observe nature and the multitude of
environments that comprise it is an extremely important factor in the study of ecology. Dumping sewage effluent in the middle of a small pond is not
going to register even a slight disturbance on a global or even regional scale , but there is a still massive disturbance to the organisms at the small scale
of that pond ecosystem. Similarly, ... Show more content on Helpwriting.net ...
Large–scale variations in these gradients are easy to observe, like an ecotone transitioning grassland into desert. Smaller scale variations are harder to
detect with the naked eye, and micro–variations in habitat are harder to see still. The physical size of environmental heterogeneity / variation is not
indicative of its importance to biodiversity or its ecological relevance, however, as Hutchinson reveals in his 1959 paper. He discusses the importance
of the mosaic nature of the environment as a significant contributor to biodiversity. While large–scale variations in habitat are certainly important
factors in organismal diversity and are responsible for niche differentiation, smaller scale and even microscopic habitat variations are arguably just as (if
not more) important factors that contribute to biodiversity around the globe. Because the vast majority of animal species on Earth are physical small,
even the tiny variations in a landscape that define its mosaic nature allow for more numerous and specialized niche differentiations than larger (and less
numerous) land animals can fill . Hutchinson's mosaic nature postulate was an extremely important breakthrough in modern Ecology, and helped
spawn further research into the importance of examining nature at many different scales – microscopic, macroscopic, and everything in between.
Scale is an extremely important

A Study On Ecosystem Profile
Part A: Ecosystem Profile
On the 10th and 11th of August, Year 11 Biology students from Trinity Lutheran College went on a fieldwork excursion to monitor the quality of water
in the surrounding ecosystems of 3 lakes in the Gold Coast region.
Aquatic ecosystems are an integral part of our environment and play an important role in maintaining the quality of water. The quality of water is
important in lakes because it doesn't just protect the health of the public but it also provides ecosystem habitats, contributes to recreation and tourism
and is used for fishing, mining and farming. It's essential to measure the quality frequently so biotic and abiotic features are surviving in a sustainable
ecology. If the quality isn't maintained, not only will the environment suffer but the recreational and commercial value of water resources will also
reduce (NSW Environment and Heritage, 2014). Water quality is measured using different tests to investigate the pH, temperature, salinity, suspended
solids, light penetration, nitrates and phosphates.
pH
The pH of water is a measure of its degree of acidity or alkalinity (Biology Textbook). Its scale has a minimum of 0 and maximum of 14. The higher
the number the more basic it is, the lower the number, the more acidic it is. A pH of 7 is considered to be neutral. The pH of water determines the
biological availability and solubility of chemical components including nutrients and heavy metals (Department of Ecology, n/d).

Grazing ecosystems support more herbivore biomass than any other terrestrial habitat (Sinclair 1975, Detling 1988, McNaughton et al. 1989, 1991,
Huntly 1991). A functional consequence of this disparity in trophic structure emerges by comparing the relationship between aboveground production
and herbivore consumption in the Serengeti and Yellowstone ecosystems with that in other terrestrial ecosystems [ILLUSTRATIONFOR FIGURE 3
OMITTED]. For consumption measurements, we included plant material removed by all important herbivores, both vertebrates and invertebrates. All
values were energy equivalents (kJ), converted from biomass measurements using standard conversion factors (Golley 1968). For productivity
measurements, we considered only ... Show more content on Helpwriting.net ...
Consumption also is higher in the Serengeti (average = 7737 kJ [multiplied by] [m.sup.–2] [multiplied by] [yr.sup.–1], SE = 911) than in Yellowstone
(average = 1332 kJ [multiplied by] [m.sup.–2] [multiplied by] [yr.sup.–1], SE = 406), as is the percentage of production consumed, 65% (SE = 4)
versus 40% (SE = 5).
Continued from page 2
There are two caveats to our interpretation of these findings. The first is that tropical forest habitat cannot be confidently classified with a single sample.
The second is that our analysis does not include combined production–consumption data for tundra grazed by herds of caribou or reindeer (Rangifer
tarandus). The two high–consumption tundra samples in Figure 3 were from sites experiencing rodent outbreaks, indicating that tundra can support
high episodic rates of herbivory. However, whether ungulate–grazed tundra supports the

The Management Of Coarse Fisheries Of Lakes And Rivers...
Introduction:
The aim of this literature review is to determine why set of structured points or methodology for the management of coarse fisheries of lakes and
rivers within the UK, is the best way forward to achieve a good ecological status of surface water bodies in the UK. The following critical literature
review will attempt to explain why achieving a good ecological status is necessary, what it is and why being applied to fisheries with UK is the most
practical approach, the themes examined will be:
1.Fisheries within the UK and their significance

Other uses involve fisheries for harvesting of fish, such as salmon farms. In 1994 there were an estimated 0.8 million game anglers and 2.3 million
coarse anglers. (Peirson, Tingley, Spurgeon, Radford, 2001, p.416). Annual expenditure on all items related to angling/fishing involved the purchasing
of rod licences from the Environment Agency, tackle, bait, and permits on private lakes as well as travel by anglers, in 1994, the total was estimated
to be approximately ВЈ3 Billion (Moon and Souter, 1994). By 2005 approximately thirty million days were fished by anglers on UK fisheries which
was substantially more than the year 2000 (Mawle, Peirson, 2009, p.44.) This increase in angling activity increases competition between fisheries to
ensure that the best quality stocks of fish are available for anglers.
It is estimated by (Girdler, Wellby, Welcomme, 2010, p.3) that approximately 90% of the still water bodies in the UK may be privately owned and
marketed or operated as fisheries. Whilst running as a privately owned fishery this could mean the fishery ends up removed from the direct influence of
significant regulating bodies such as conservation, freshwater scientists and regulators like the Environment Agency, thus emphasising the role that
fishery managers must independently regulate the aquatic environment of their freshwater body. One of the main reasons as to why it is so significant to

In the aforementioned paper, the triple ecological threat is described as "environmental degradation, climate change, and peak oil", they further
describe how this correlates socioeconomically, and what can be done to change current ecological trends from a sociological standpoint (Poland,
Dooris, & Haluza–DeLay, 2011).
Environmental degradation reduces the carrying capacity of the affected area on a permanent or temporary basis (Matthews, 2014). This definition
has intentionally been left as a sweeping generalization because our land, hydrosphere, and air are all possible subjects of environmental degradation
from many different sources (Matthews, 2014). Climate change, which is a persisting climatic change, is evidence of disruption in previously stable
ecological cycles ("Climate Change Basics", 2014). According to the EPA, climate change is evidenced by the overall temperature increase of our
earth by 1.4В°F, as well as changes is weather patterns ("Climate Change Basics", 2014). Peak oil is the maximum rate of oil production, past which
the production rates will continually decline (Poland, Dooris, & Haluza–DeLay, 2011).
This triple threat will affect those of lower socioeconomic statuses more directly than those with higher socioeconomic standing. Hydrosphere
degradation may include pollution of drinking

The Effects Of Climate Change On The Planet
The effects of climate change have become more apparent than ever within the last 100 years. Increasing climates have been proven; with the
warmest temperatures in 30 years being recorded (Houghton, 1994). Suggested cause of this increase is population change, the ever increasing
demand for natural resources to sustain economic growth has resulted in exploitation of ecological systems at a rate never recorded before. These
huge changes to the planet will have a knock on effect to individual and global ecosystems resulting in varying levels of positive feedback.
Throughout this essay I will be discussing on various ways climate change effects the ecology of the planet.

Evidence such as the rising of sea level by 17cm in the last century or the 150–250km3 loss of Greenland ice per year between 2002–2006 (NASA,
2014) proves that climate change is happening to us currently and the effects are immediate.
The Carbon Cycle consists of the vital components for all animal and plant lives. It is primarily a reflection on primary and secondary production
(Krebs, 2009). As seen in Figure 2, carbon levels have not been constant throughout history. Figure 3 represents the basic components of the Carbon
cycle. The diagram shows that the oceans are the largest sink of carbon, and is at a constant equilibrium of atmospheric CO2 and aqueous CO2.
The increase in atmospheric CO2 levels causes ocean acidification by decreasing the pH of the oceans. PH values are said to have dropped by 0.1pH
units since pre industrial levels and are expected to drop a further 0.3 units by the end of the 20th century (Scott C Doney, 2007). This chemical change
will have knock on affects in many marine ecosystems, which will be discussed later.
However, there are positive results of the rapid increase of CO2 in relation to plants a; CO2 enrichment will no longer be a limiting factor of
photosynthesis. Evidence of this is results from 3,586 separate

Global Warming And Its Effect On Ecosystems By Stimulating...
Abstracts
The uses of microcosm are resourceful in giving insight into the behaviors of larger scale systems. global warming is increasing at escalating rate and
could affect ecosystems. Ecosystems are a very important part of humanity as they provide us with essential services to survive. It is important to know
the factors that could affect this. The use of microcosm experiments can be used to give information into how ecological communities will be affected
by climate change. In this study sampled populations of the species Paramecium and Euglena were taken over 5 days at different temperatures using
PCR, Microscopes, Serial dilution and spectrophotometry techniques. The results gathered form over the 5 days showed that increasing temperature
over time has an effect on the microcosms, negatively and positively. This experiment proved that the increase in temperature through climate change
has an effect on ecosystems by stimulating reproduction, interaction and competition.
Introduction
Climate change through changes in the environment is rapidly increasing and creating a negative impact on ecological services provided from
biodiversity.
Ecosystems are essential to the sustenance of humanity as they provide us with many useful services like food, energy, water and recycling. (Benton et
al., 2007)
An ecosystem is made up of different types of plant and animal species which interact with each other and most importantly with their environment as
one functional unit. The

The Consequences Of Soil Diversity
The human population is projected to reach 10 billion by 2050. This growth will demand almost twice of currently globally produced agricultural
products. However, long periods of intensive agriculture have resulted in soil nutrient depletion, salinity accumulation, and acidification of agricultural
soils, resulting in an overall reduction of the soil's ability to support a growing population (Godfray et al., 2010; Smith et al., 2013, Tillman et al 2011,
Ray et al 2013). Despite the fact that soil is one of the mankind's most essential and threatened resources, supporting food production, wildlife

Moreover, these studies have only a limited focus on the fate of environmental mobile element under environmental changes. Thus, in order to access
the real complexity of species interactions the future studies MUST consider simultaneous measurements of multiple functions (Cardinale et al. 2012,
Duncan et al. 2015) including rates of genetic information exchange encoded by mobile elements. Thus, throughout my scientific career, I have been
motivated to address fundamental and practical questions associated with soil microbial ecology that are pivotal to many ecosystem services. My
primary research projects have involved: increasing carbon dioxide sequestration by enhancing the photosynthetic efficiency of plants (M. Sc. thesis);
stimulating plant productivity and disease resistance through biochar soil amendments (Ph.D. thesis); and determining the fate of phenolic compound

NSF proposal that would investigate population crashes of this same invasive crayfish and, if funded, would mean the selected student will be

be beneficial to both of us, and that we will be able to produce meaningful publications as a result. I am excited to help determine whether or not
laboratory behaviors of an invasive species can tell us anything about their field function, including how they fit into the aquatic food web and whether
controlled lab experiments might be a useful tool in determining how we manage invasive

Energy Flow Among Organisms of a Food Chain in the Desert...

The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it
does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For
example, one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able to drink the rain
water. They also have think skins which are a protection from the heat along with the fact that its stems grow upward instead of outward protecting it
from the sun (Big Site of Amazing Facts, 2013). The cactus is also an expert ... Show more content on Helpwriting.net ...
In the desert biome, no organism would be able to survive without another organism. Their interactions are constant. Plants provide shelter and food
for animals and animals help to pollinate and grow flowers (Bailey, 1999). One example of the interactions of organisms in the desert is between
birds and other small animals and the cactus. Desert birds and animals that are small enough to navigate between cacti sharp needles use the cactus
for shelter and for water. Another example would be how bats spread pollen from one part of a cactus to another part which helps the cactus grow
flowers. The Joshua tree makes fruit in which animals eat, too. These are all examples of how organisms in the desert interact with each other.
Although animals living in the desert have had to evolve in order to adapt to the desert conditions, those conditions are very fragile. The desert may be
a hard place for non–natives to survive, but the desert's ecosystem is very sensitive and not easy to regenerate. "Development, off–highway vehicle use,
livestock overgrazing, construction of roads and utilities, military training exercises, air pollution and the spread of non–native plant species have
seriously altered the desert ecosystem over the last century" (Barton, 1999). These are the hazards by humans that are directly affecting the ecosystem
in the desert. According to Barton (1999) the off–highway vehicle use, construction, overgrazing, and military usage damages the desert's

The Value Of Taking Responsibility Essay
The Value in Taking Responsibility During the late 1800's and early 1900's a series of laws and campaigns were instated to prevent forest fires. It
was believed that forest fires would greatly damage the timber industry due to the loss of trees the forests would suffer as a result. The longer these
campaigns persisted, the worse the forest fire breakouts became, and the forests continued to degrade. Many animals were also displaced and
threatened as a result of these intense fires. Eventually forestry researchers and conservationists started looking at what fires did to the various
ecosystems. They found that fires actually promote the growth of healthier, stronger trees by burning the weak trees and providing more nutrients for
the soil. By suppressing fires, the forests experienced large amounts of degradation, and many animals were threatened by the loss of sustainable
habitats. Controlled burns every few years actually benefits all the organisms living in that ecosystem, however, in some places it's nearly impossible to
burn. After so many years of fire suppression the leaf litter has accumulated to such large amounts that any fire started would burn to hot and high for
the forest to survive. Human interests often times have profound affects on the world around them. There are many instances like the above example in
which peoples own self–interests end up hurting and degrading the environment around them. In the aftermath of events such as this, there are many

Symbiotic Lion King
Ecology is how organisms interact with each other and the environment. The Lion King is linked to ecology by showing how organisms interact with
each other and the environment. My three topics are how symbiotic relationships are important to a community, how limiting factors affect a
community, how communities respond to abiotic or biotic factors, and how this is linked to the movie and Ecology. Symbiotic Relationships are
interactions between two species and how they affect each other. There are three different types of symbiotic relationships Mutualism, Commensalism,
and Parasitism. Symbiotic Relationships are related to ecology because they both talk about interaction with others. One example from the Lion King
is when the birds go onto the tusk of the elephant. This is an example of Commensalism because the birds are eating insects off the Elephant's tusk and

These factors will affect how organisms will behavior and how organisms will survive. An example is when the hyenas came to pride rock. This is
a biotic factor because it affected the whole pride land by making the herds leave and making everyone hungry. Another example is when water
became scarce in the pride land. This is an Abiotic factor because it made the populations leave the pride land and everyone scours for water. The
examples from the movie happen in real life because when someone like the hyenas comes to a community they always disrupt the community. An
example from real life is in the Tundra, plants have to adapt to the very long cold winters because the sun does not come up. This is an example of
Abiotic factor because it shows the plants have to respond in order to survive. The examples in the movie and the real life example have much
common. The animals and plants both have to respond to changing abiotic and biotic

Biodiversity And Its Effects On Biodiversity
Abstract. Biodiversity is a variety of life and it is important to maintain biodiversity because it provides everyone's needs for food source, water source
and shelter. Currently, Georgia Gwinnett College expanding with construction around the area, will this cause a disturbance where the campus will not
be able to have biodiversity or having some disturbance can increase it? The research measured biodiversity in 5 different places around campus, these
locations varying levels of disturbance and resources. After analysis, it was determined that sites further away from the stream at the downstream
location had less biodiversity, and that the GGC site location had more biodiversity than both of the stream locations, which may be due to more
diverse habitats with the location, or sharing more transition areas with areas of higher disturbance.
Introduction. Biodiversity is a variety of life on Earth at all levels from genes to ecosystems and the ecological and evolutionary process that is able
to keep biodiversity in balance (Willington, 2005). Biodiversity is important because it satisfy's everyone including animals, organisms and humans
basic needs such as food and water source and as well shelter(Wood, 1997). The overall goal in biodiversity conservation is to create a foundation in
developing ways to protect and use biological resources in a way where it does not destroy important habitats in an ecosystem (Nangendo, 2002). In
ecology it has been taught that everything from

Invasive Species In Yellowstone Lake
An invasive species is a plant, fungus, or animal species that is not native to a specific location and one point should be noticed is that invasive
species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species
in Yellowstone Lake because they compete with native cutthroat trout for habitat. Although there are some invasive species arrive with spread and
establish populations, like the native butterflies feed on non–native plants in California, the alien trees help restore abandoned pastures to a condition
suitable for native plants in Puerto Rico and even the much–maligned zebra mussel helps filter toxins from great lakes, most policymakers regard

A Community Of Organisms With Their Environment
An ecosystem is a system formed by the interaction of a community of organisms with their environment. Ecology is a branch of biology having to deal
with the relations and interactions between organisms, their environment, and other organisms. A community in an ecosystem is an assemblage of
interacting populations occupying a given area. A habitat is an area or environment where an organism or an ecological community lives. There is a
large diversity in an ecosystem, for example, the species, environment, and the plant diversity in the ecosystem. It's difficult to model ecosystems
because the model needs to be accurate and as well as precise.
In an ecosystem, organisms have many ways to get energy. One way is a producer, who makes their own food. Only plants have this ability.
Another way is being a consumer, who eats other organisms for food and energy. An example of a consumer would be animals and humans. Lastly,
another way organisms can get food is being a decomposer, one who eats dead plants or animals. Decomposers are mostly bacteria, fungus, or
invertebrates. A food web is a series or organisms related by predator–prey and consumer resource interactions. It is entirety of irrelated food chains in
an ecological community. There is also a trophic level. A trophic level is any class of organisms that occupy the same position in a food chain such a
primary consumers, secondary consumers, and tertiary consumers. An autotroph is an organism that is capable of making
