Ecology is the study of the relationships between organisms and their environment. The key levels of organization in ecology are organisms, populations, communities, ecosystems, and the biosphere. Populations grow according to exponential or logistic growth models depending on whether resources are unlimited or limited. Species interact through predation, competition, parasitism, commensalism, ammensalism, and mutualism. Abiotic factors like temperature, water, light, and soil influence organisms and drive adaptations.
This document discusses key concepts in ecology including organism level, population, biome, niche, adaptation, and population interactions. It defines population as a group of organisms of the same species that can interbreed. Biomes are characterized by dominant vegetation and formed due to variations in light, temperature, and precipitation. Organisms respond to abiotic factors through regulating, conforming, partial regulating, migrating, or suspending activities. Adaptations help organisms survive in different environments like deserts and high altitudes. Population interactions include predation, competition, parasitism, commensalism, and mutualism. Population growth can be exponential or logistic depending on resource availability.

This document discusses ecology and the levels of organization in ecology from organisms to biomes. It describes abiotic factors like temperature, water, light and soil that influence organisms and biomes. It also discusses biotic factors like pathogens and predators. Several biomes are described that are formed based on annual temperature and precipitation variations. The document discusses population attributes, growth models, life history variations, and population interactions like competition, predation, parasitism, commensalism and mutualism. Adaptations of organisms to the environment are also summarized.
Ecology is the study of how organisms interact with each other and their environment. A population is a group of the same species that lives in a defined area, and multiple populations make up a biological community. An ecosystem consists of all the living and non-living things in a particular environment that interact, such as a rainforest. Ecosystems are influenced by biotic factors like competition and symbiosis between organisms, as well as abiotic factors like climate and resources. Population growth follows a sigmoid curve as it increases rapidly at first but then levels off at the environment's carrying capacity.

Key biomes are defined by their location and characteristic environmental conditions.
1. Species diversity refers to the number and variety of species in a given region. It takes into account both the number of species and how evenly abundant they are.
2. There are three main types of species: endemic, exotic, and cosmopolitan. Endemic species are restricted to a particular area while exotic species have been transported by humans.
3. Factors that affect species diversity include speciation, extinction, migration, habitat destruction, and the introduction of invasive species. Speciation occurs through geographic isolation or reductions in gene flow. Extinction can be caused by overharvesting, pollution, and habitat loss.
Diversity stability debate and its relevence in pestsRanjeet Verma
This document provides an overview of relative distribution of organisms and biodiversity. It discusses the different patterns of distribution organisms can have, including continuous, discontinuous, species-level, and clumped distributions. It also defines biodiversity as the variety of life on Earth, including genetic, species, and ecosystem diversity. The document outlines some of the key principles of biodiversity, like the importance of native species and connectivity between habitats.
This document discusses biodiversity and the threats facing many species. It defines threatened, endangered, and extinct species and explains the differences. While there have been natural extinction events in the past, the current "6th extinction" is caused by human activities. Specialist species with small populations are most at risk. The main human threats are habitat destruction, invasive species, pollution, poaching, and overharvesting. Tropical rainforests, coral reefs, and islands have extremely high biodiversity but are being rapidly degraded. "Biodiversity hotspots" face especially high threats and have lost 70% of their original habitat. Some biodiversity hotspots in the US include the Everglades, Midwest prairies, and
Predators around the world are facing extinction rates hundreds to thousands of times higher since human introduction. The removal of top predators from ecosystems has disrupted the regulatory balance and decreased biodiversity. Without predators controlling prey populations, prey species multiply rapidly which overtaxes resources and decreases diversity within the prey community through the "Paine effect." Trophic cascades occur when changes in one part of the food chain impact other levels, and they demonstrate the importance of predators in maintaining ecosystem integrity.

Beautiful, graphic rich slides to engage students based on Essential Environment by Withgott and Laposota. Slides cover Chapter 3 evolution, biodiversity and population ecology
The document discusses several key points about endangered species:
1) Aldo Leopold argued that if the land mechanism as a whole is good, then every part of it is good, whether we understand it or not, and we should aim for harmony with the land.
2) Endangered species are so few that they could become extinct, while threatened species are likely to become endangered due to declining numbers. Many experts believe 1/3 of plant and animal species in the US are threatened.
3) The current rate of extinction is estimated to be 1,000-10,000 times greater than before humans due to factors like habitat loss and climate change.
1. The document discusses biodiversity conservation and provides definitions and examples related to indicator species, biotic indices, in situ and ex situ conservation methods, and factors that affect biodiversity like island size and edge effects.
2. It gives examples of using lichens and invertebrates as indicator species to monitor air and water pollution. Simpson's reciprocal index of diversity is also defined as a measure of biodiversity.
3. Case studies are provided on conserving the California condor through captive breeding and reintroduction, and protecting biodiversity in the Coral Triangle region through large nature reserves.

Ecology is the study of interactions between organisms and their environment. It examines these interactions at four levels - organisms, populations, communities, and biomes. The major biomes in India include tropical rainforests, deciduous forests, deserts, and sea coasts. Within these biomes, populations of organisms interact through predation, competition, and parasitism. Predation involves a predator species consuming a prey species, while competition lowers the fitness of species competing for the same resources. Parasitism benefits one species through deriving food or shelter from another host species.
Ecology is the study of interactions between organisms and their environment. There are several levels of ecological organization from individual species to ecosystems. Species interact through relationships like competition, predation, and various types of symbiosis such as mutualism, commensalism, and parasitism. Organisms exhibit adaptations like mimicry and camouflage that allow them to survive within their ecological niches. North Carolina contains various ecosystems including coastal, estuary, forest, and urban environments.
The document discusses biodiversity, which refers to the variety of species on Earth and their habitats. It notes that scientists estimate there are 10 million to 100 million species, and each is adapted to its unique ecological niche. Biodiversity underlies important areas like food, medicine, and ecosystem health. However, habitat destruction and overexploitation are causing a current mass extinction that may be as severe as those of the past. Efforts are underway to preserve biodiversity through laws, international agreements, and sustainable practices.
This document discusses the challenges of sustaining life outside of established ecosystems, using the example of Biosphere II. A group of researchers built a sealed living space called Biosphere II in the desert of Arizona to experiment with sustaining a small group of people for 2 years without external resources. While they were able to survive, it showed how delicate the balance is between air, water, and life. Maintaining this balance is complex and actions can have unintended consequences. The experiment helped increase understanding of what would be needed to establish bases on other planets or celestial bodies.
This document describes the interactions between living things and their environment. It discusses the biotic and abiotic components of the environment. Organisms interact with both components and have a niche defining how they obtain resources and interact. Ecology is the study of these interactions within and between species and their environment. The document also describes the organization of living things from individual to population to community to ecosystem to biosphere. It outlines different types of interactions like competition, predator-prey relationships, and symbiosis.
This document provides an overview of key concepts in ecology including the biosphere, biomes, ecosystems, and nutrient cycles. It defines important terminology like community, biome, abiotic and biotic components. It describes the major biomes like tundra, grasslands, forests and aquatic biomes. It explains how ecosystems are structured, including producers, consumers, and decomposers. Energy flows through ecosystems in food chains and webs. Nutrients like carbon, nitrogen, and water cycle through the biosphere and are reused by organisms.
Andy Moldenke - Insects in Early Seral HabitatsEcoshare
The document discusses how insect communities differ between open canopy and closed canopy forest environments. It finds that about 50% of total arthropod species are only found in early succession open canopy areas in the short time after clearcutting. Open canopy areas tend to have higher species richness and abundance than closed canopy forests. Individual insect species, functional guilds, and whole taxa have different preferences and responses to shade versus sun conditions. Riparian zones also have distinct insect communities that can extend 50-70 meters from the stream, with higher richness and abundance closer to water.
The document defines key terms in ecology, including:
- Ecology as the scientific study of interactions between organisms and their environment that determine distribution and abundance.
- Ecosystem as a natural unit composed of living and non-living components whose interactions lead to a self-sustaining system.
- Biome as a large region characterized by distinct climate and life forms adapted to it, such as tropical rainforests, savannas, and tundra.
The leatherback turtle is critically endangered and listed on the IUCN Red List. It is the largest sea turtle and can be found in over 70 countries. The harvesting of eggs on beaches and ocean pollution from plastic waste are major threats. If extreme measures are not taken to limit pollution and reform fishing practices, these unique deep-diving turtles that have inhabited our oceans for over 100 million years may become extinct. International cooperation is needed to prevent the extinction of this migratory species.
Save the Frogs Day, Professor Hero, Griffith University 2012JMHero
Global amphibian populations are facing a crisis, with over 32% of species threatened with extinction and 122 species having disappeared since the 1980s. In Australia specifically, at least 5 species have gone extinct since 1979 and many more are experiencing declines. Possible causes of these declines include invasive species, overharvesting, habitat loss, contaminants, emerging infectious diseases like chytridiomycosis, and the effects of global climate change. Researchers at Griffith University are working to understand the causes of declines and conduct conservation efforts like habitat restoration and establishing captive breeding programs to save critically endangered species like members of the Taudactylus genus of frogs. Public involvement through activities like protecting local wetlands and reducing chemical use can help address

The document discusses conservation efforts for giant pandas. It provides background on pandas, listing their scientific name, habitat, lifespan, diet, and conservation status as vulnerable. Threats to pandas include habitat loss and hunting. The World Wildlife Fund works to protect pandas through conservation education, international breeding programs, expanding protected areas, and anti-poaching patrols. Assisted reproduction techniques being used include artificial insemination, embryo transfer, and somatic cell nuclear transfer. These require knowledge of reproductive cycles and invasive procedures. Genome resource banking also aims to preserve genetic diversity. While promising, ART has inconsistent results and requires more research versus immediate wildlife needs.
The document discusses biodiversity loss and conservation efforts. It notes that the current extinction rate is 100-1000 times faster than historical rates due to human activities. The four main causes of extinction are habitat loss, overexploitation, invasive species, and co-extinction. Conservation efforts aim to protect biodiversity through both in situ and ex situ methods. In situ approaches include biodiversity hotspots, sacred groves, and protected areas like national parks and sanctuaries. Ex situ involves zoos, botanical gardens, gene banks, and cryopreservation. International agreements like the Earth Summit and World Summit address conservation goals.
This document discusses ex-situ conservation, which involves removing species from their natural habitats and placing them in human care, such as in zoos, seed banks, and gene banks. Ex-situ conservation is often used as a last resort when populations become too small and are at high risk in their natural environments. While not ideal, ex-situ conservation helps preserve biodiversity through various techniques like captive breeding programs, botanical gardens, and gene banking. It faces challenges but can be an important part of conservation when used strategically along with in-situ methods.
Conservation biology is an applied science devoted to preserving life diversity. It draws on knowledge from various disciplines to understand threats to biodiversity and develop strategies for conservation. The current extinction crisis is unique in that it is human-induced. We value biodiversity for ecological, economic, scientific, and ethical reasons. However, habitat destruction, exotic species introduction, overexploitation, and climate change are major threats driven by human activities. Conservation strategies include protected areas, restoration ecology, and controlling invasive species.
This document discusses ex-situ conservation. Ex-situ conservation involves protecting endangered species outside of their natural habitats, such as in zoos, botanical gardens, seed banks, and captive breeding programs. The document provides examples of ex-situ conservation, including seed banks and gene banks. It also discusses the California condor captive breeding program as a case study of a successful ex-situ conservation effort that helped save the species from extinction.

Charles Darwin developed the scientific theory of evolution by natural selection to explain how species change over time through descent with modification from common ancestors. His theory states that genetic variation within species leads to different traits, which are acted on by environmental pressures like competition for resources and predation. Traits that increase survival and reproduction become more common in populations over many generations, resulting in evolution of new species. Darwin provided extensive evidence from biogeography, fossils, embryology and comparative anatomy to support his theory.

Endangered species are at risk of extinction due to threats like habitat loss, hunting, and climate change. Conservation aims to protect biodiversity by preserving habitats, restoring degraded areas, and protecting species. Some common conservation actions include habitat preservation, restoration, captive breeding programs, anti-poaching measures, and wildlife corridors. Individuals can help endangered species by reducing their environmental impact, supporting conservation organizations, and volunteering.
This document discusses endangered and threatened species in the Philippines. It outlines several major threats to biodiversity like habitat loss, introduction of invasive species, overhunting, climate change, and more. Certain characteristics make species more vulnerable to endangerment, like large size, specialized diets/habitats, low reproduction rates, and small population sizes. Endemic and rare species are at high risk due to limited distributions. The document reviews criteria used by IUCN to evaluate endangered species status and lists numbers of threatened species in the Philippines according to these criteria.
This document discusses several ways that humans negatively impact the environment, including habitat destruction, invasive species, population growth, pollution, and overuse of resources. It provides examples of each using the cheetah as a mascot species. Habitat destruction from deforestation, development, and fragmentation has reduced areas cheetahs can live. Invasive species like humans threaten cheetahs through conflicts and poaching. Large human populations stress resources and contribute to other issues like pollution. The examples show how climate change, water and air pollution, and over-hunting of cheetah prey due to human overuse of resources all threaten cheetah survival.
This document summarizes WWF-UK's key issues and conservation efforts. It addresses protecting endangered species, forests, rivers and wetlands, seas and coasts, as well as addressing global threats like climate change and toxic chemicals. Specific examples are provided of WWF's work conserving species like elephants, rhinos and gorillas, as well as protecting forests in Mexico and restoring degraded forests. The challenges of freshwater conservation due to population growth and water management are also outlined.

A species is defined as a group that can breed and produce fertile offspring, though hybridization and asexual reproduction complicate this definition. Biodiversity refers to the number and variety of species in an ecosystem, including the genetic diversity within species and structural diversity of physical conditions that support different species, many of which depend on one another through interactions like predation, symbiosis, and food chains.

Assessment and Planning in Educational technology.pptxKavitha Krishnan
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.

2. Introduction
There are only

the world
Global warming
Global Warming measurable increases in
the average temperature of Earth’s
atmosphere, oceans, and landmasses. Scientists
believe Earth is currently facing a period of rapid
warming brought on by rising levels of heat-
trapping gases, known as greenhouse gases, in
the atmosphere.

Organisms can be carried around the
world in holds of ships, stuck inside the

Survey
For survey such as those such as those as those
carried out for the red list (up, right) be valid and
useful, they have to carried out scientifically.
Observations and record must be precise and
accurate. Everything about the survey must be
kept exactly the same every time observation are
repeated, change in the number of individuals
counted.
5. Why is conservation important?
Nothing in natural world in constant. However,

and on their plant and animals. Spices are
being extinct everyday. Conservation is
important because it aims to protect the
natural world, to prevent species going extinct
as a result of man’s activities and to prevent
further habitat damage.
Conditions for life
All living things have basic requirement in order to
survive. In the case of the polar bears shown right, the
arctic , with an adequate food supply. They must be safe
from predators and able reproduce. If all of these are
present they will survive.
6. Protecting areas
One of the one main the conservationists seek
Elephants are killed for to protect areas. These are areas in which all of
their tusk(now banned
but still are killed) organisms in an area - whether the habitat is
desert, woodland, wetland, or a coral reef in the
sea- are protected from hunting, deforestation
and other damage.
Science or tourism
Some people think it is most important to
protect the scenery, particular as that is what the
general is interesting in. The beauty of protected
areas brings tourism and with in money. On the
other hand, many conservationists argue that the
entire ecosystem is what matter most, less
attractive species .
7. Into the future
Egg donor
Scientists remove an egg cell
from a female sheep and
extract the nucleus
containing genetic material
from the egg cell to form an
enucleated cell.
Genetic donor
At the same time, scientists
collect a cell containing a
nucleus with genetic
material from a second
sheep. The nucleus from the
donor cell is removed.
Enucleated cell and nuclear
fusion
Scientists use electricity to
fuse the enucleated cell
from the egg donor with the
nucleus from the genetic
donor.
Embryo development
The fused egg cell and
nucleus divides and grows to
form a sheep embryo.
Embryo implantation
Scientists implant the sheep
embryo into the uterus of a
third sheep, which acts as a
surrogate mother.
Birth of clone
The surrogate mother goes
through a normal pregnancy
and gives birth to a sheep
that is a clone of the genetic
donor.

There are two groups of whales: Toothed

and baleen. Blue whales are largest
creature ever to have lived on earth. If
whales swim too close to the shore they

places, the blue whale populations are now
growing in size. Climate change may mean
many blue whales will die lack of food.
Continued threat
Between 1904 and 1967, more than
350,000blue whales were killed in the
southern hemisphere. In 1967,they were given
legal protection, not all countries with this.
9. Case study- rain forest

Half of all animals and fact file
plant species in the
world live in Rainforest once covered around
rainforests
14% of the earth’s land surface.
Today they cover just 6% and if it
continued it will disappear in 40
years. Rainforest plant have been

of years . Economic assistance
from rich countries can help to
save rainforests areas. 500 years
ago there were around 10 million
Indians living in Amazonian
rainforest. Now there are less

than 200,000.
Trees are cut down for their wood, such as
mahogany, which is valuable. The process of harvesting
the wood destroys everything else around it too, as
habitat vanish, soil is lost due to erosion and air and
water are polluted.
11. Caution !!!
War, in international law, armed conflict
between two or more governments or
Armored Soldiers
states. When such conflicts assume global
in Battle
proportions, they are known as world
wars. War between different parts or
factions of the same nation is called civil
war.
Click on image
to watch A rebellion is not legally considered a war;
to entitle the armed forces of the rebels
to the rights and privileges of
belligerents, the government they serve
must be organized so as to be in a
position to meet the duties resting on
belligerents, that is, they must have the
power to maintain law and order within
the regions occupied by them and to carry
on war on a large scale by land, sea, or
air.
International
International hostilities sometimes continue for long periods of time
without being acknowledged as wars. The Korean War was
regarded by the U.S. government as a police action. Conflicts or
wars in which major powers purposely refrain from employing all
their armed strength are often known as limited wars. Short of
peace, such limited wars are now recognized as a preferable
alternative to the specter of nuclear war.International wars are
generally terminated by treaty, and civil wars by a peace
proclamation. The usages, customs, and treaties of nations have
formed a system of laws of war.
12. Conclusion- death or peace
Death and sacrifice for

who understand it.
World war 1
World War I, military conflict, from August 1914 to November 1918, that involved
many of the countries of Europe as well as the United States and other nations
throughout the world. World War I was one of the most violent and destructive
wars in European history. Of the 65 million men who were mobilized, more than
10 million were killed and more than 20 million wounded. The term World War I
did not come into general use until a second worldwide conflict broke out in 1939
(see World War II). Before that year, the war was known as the Great War or the
World War.

Global Warming or Climate
Change, measurable increases in the average
temperature of Earth’s
atmosphere, oceans, and landmasses.
Scientists believe Earth is currently facing a
period of rapid warming brought on by rising
levels of heat-trapping gases, known as
greenhouse gases, in the atmosphere.
Greenhouse Effect
Greenhouse Effect, the capacity of certain gases in
the atmosphere to trap heat emitted from Earth’s
surface, thereby insulating and warming the planet.
Without the thermal blanketing of the natural
greenhouse effect, Earth’s climate would be about
33 C (about 59 F) cooler—too cold for most living
organisms to survive.
16. Greenhouse started 200 years
ago

How global warming???
17. Pollution
Pollution, contamination of Earth’s
environment with materials that interfere
with human health, the quality of life, or the
natural functioning of ecosystems (living
organisms and their physical surroundings).
Although some environmental pollution is a
result of natural causes such as volcanic
eruptions, most is caused by human
activities.
18. How to heal the world???
Use the RRR (Recycle reuse and you know) formula .
Make your caste humanity not Muslim, Indians, etc.
Instead of deforestation use you common sense
(reforestation).
Distribute your book who effort them.
Read red data book and watch channels like
discovery, news, etc.
Save your fuel and while save your time, money and start of
something big.
If you see them as animal we were even some day those or
we are now worst.
Teach them the way or describe them the way as you teach
.
World is not that big you think the way to heal maybe in
meters or even in centimes sometimes even less.
