This document discusses disturbance ecology and different approaches for estimating characteristics of ecological communities, analogous to methods for estimating the number of books in a library. It defines ecological disturbance as discrete events that disrupt populations, communities, and ecosystems. Disturbances are regular, predictable events that species can adapt to, unlike rare disasters. The frequency, location, magnitude, and intensity of a disturbance regime can affect evolutionary adaptations and species diversity within a community.

Conservation Biology [Group 4]
General Botany Group four presentation.
This presentation focus on so many biological related topics. It primarily focus on conservation of life in any biodiversity.
Species interaction
This document discusses several key concepts related to species interactions, including predation, coevolution, warning coloration, mimicry, cryptic coloration, competition, symbiosis, succession, and ecological niches. It describes how predation influences population balances and drives adaptations in prey. Competition and different symbiotic relationships like mutualism, commensalism, and parasitism are also outlined. Ecological succession and the fundamental versus realized niche concept are briefly defined.
The measurement of biodiversity
This document discusses various methods for measuring biodiversity, including species richness, evenness, disparity, and genetic variability. It notes that biodiversity cannot be reduced to a single number due to the complexities of various taxonomic concepts and differences in ecosystems. While higher productivity generally correlates with greater biodiversity, preserving biodiversity poses challenges for policymakers given difficulties in comparing biodiversity across environments.
Community Ecology
The document summarizes key concepts in community ecology:
1. Community structure is described by physical appearance, species diversity, and niche structure.
2. Species diversity is influenced by factors like latitude and pollution.
3. The number of species on an island is determined by immigration and extinction rates, island size, and distance from mainland.
4. Species play roles like native, non-native, indicator, keystone, and foundation species that impact community ecology.
5.1 communities & ecosystems
This document defines key terms in ecology like ecology, ecosystem, population, community, and species. It distinguishes between autotrophs and heterotrophs, and describes the three types of heterotrophs - consumers, detritivores, and saprotrophs. It explains what a food chain and food web are, and how to determine the trophic level of organisms. It also covers energy flow through ecosystems and food chains, and how nutrients must be recycled unlike energy.
Limiting factors
Density independent and density dependent factors can limit population growth. Density independent factors like natural disasters, temperature, sunlight and human activities affect populations regardless of density. Density dependent factors like competition, predation, disease and crowding only impact populations at high densities. For example, yellow perch populations in Lake Winnipeg are limited by density independent factors like drought, which could lower water levels and temperatures, as well as density dependent factors like predation from northern pike and walleye when populations are high.
Principles of Ecology
This document discusses key concepts in ecology, including:
1) Ecology is the study of interactions between organisms and their environment. It examines relationships between living and non-living components.
2) Organisms exist within different ecological levels from cells to the biosphere. Food chains and webs show how energy flows between organisms as herbivores, carnivores and omnivores feed.
3) Populations grow over time according to exponential, logistic, or S-curve models until limited by carrying capacity due to factors like predation, competition, and crowding. Human population growth poses challenges for global carrying capacity.
Lesson 1. concept of ecology
This document provides an overview of key concepts in ecology and environmental biology, including:
1) It defines ecology as the scientific study of interactions between organisms and their environment.
2) It describes producers, consumers, food chains, food webs, and trophic levels within ecosystems.
3) It explains ecological pyramids and how energy and biomass decrease at higher trophic levels.
4) It outlines ecological interactions like competition, predation, and the three types of symbiosis - mutualism, commensalism, and parasitism.

Ecology
Ecology has a complex origin dating back to ancient Greek philosophers like Aristotle who made early observations of natural history. Modern ecology emerged in the late 19th century as a more rigorous science. Key figures included Ernst Haeckel who coined the term "ecology" and Charles Darwin whose theory of evolution was a cornerstone of ecological thought. Ecology is defined as the scientific study of the interactions between organisms and their environment, and includes variables like species distribution, abundance, and changing states within ecosystems. It is a multidisciplinary field with applications in conservation, natural resource management, and human social systems.

Extinction of biodiversity
The document discusses extinction and biodiversity loss. It defines extinction as occurring when the last member of a species dies. The passenger pigeon is provided as an example, with the last one dying alone in a zoo in 1914 after the species was already functionally extinct in the wild. Major causes of extinction discussed include habitat degradation and destruction from human activities like pollution, climate change, and overpopulation. Statistics are given on current extinction rates from human impacts being 1500 times the natural rate, with many species projected to be lost in the coming centuries if trends continue. The major impacts of biodiversity loss on human concerns like medicine, agriculture, ecosystem services, and moral obligations are also briefly touched on.
Echologicalconcepts and principles

4. chapter 2 principles of ecology
Ecology is the scientific study of the interactions among organisms and their environment. There are several key levels of ecological organization, including the biosphere, ecosystems, communities, populations, and organisms. Energy flows through ecosystems via food chains and webs, entering as sunlight and being lost as heat at each trophic level. Matter cycles through ecosystems as well, as nutrients are recycled from organisms to the environment and back again via processes like decomposition.
Biotic and Abiotic Factors
The document discusses biotic and abiotic factors that influence ecosystems and populations. Limiting factors, which can be biotic like food availability or abiotic like access to water, determine population sizes and species distributions. Each species has a tolerance range for abiotic factors like temperature, light, and soil conditions, and populations do best within an optimal range. Biotic interactions like competition for resources, predation, and mutualism also influence species success and distributions. As populations increase in size, their demand for resources increases until the ecosystem reaches its carrying capacity, or maximum sustainable population.
BIODIVERSITY LOSS AND CONSERVATION BIOLOGY
Biodiversity reflects the variety of living organisms and how they interact in ecosystems. It is declining rapidly due to human activities like habitat loss, pollution, and overexploitation of resources. This biodiversity loss negatively impacts human well-being by reducing food security, water quality, and resilience to natural disasters. Four scenarios for the future were explored that consider different levels of globalization and approaches to environmental management. All scenarios found that biodiversity will continue declining due to expanding agriculture and shrinking forests. Protected areas and market-based conservation efforts can help slow this loss if carefully implemented.
Ecological niche
An ecological niche describes how a species interacts with and fits into its environment, including obtaining resources like food and shelter, and reproducing. A niche encompasses all biotic (living) and abiotic (non-living) factors. The fundamental niche is the full range of environmental conditions a species can tolerate without competition from other species. Species niches depend on factors like temperature, resources, and predators. Niches can overlap if species partition resources in non-competing ways, like dolphins and seals eating different types of fish.
Species diversity (PLANT ECOLOGY)
Species diversity is defined as the number of different species present in an ecosystem and their relative abundances. There are two components of species diversity: species richness, which is the number of different species present, and species evenness, which is how similar the abundances of each species are. Tropical rainforests and coral reefs have very high species diversity due to favorable environmental conditions that allow for many specialized species and resilience to disturbances. However, human activities like habitat loss, overexploitation, invasive species, and extinctions are major threats and causing accelerated extinction rates. Conservation efforts focus on both in-situ and ex-situ methods to protect biodiversity.
Species Interactions
The document describes the five major types of species interactions: competition, predation, parasitism, mutualism, and commensalism. Competition involves two species attempting to use the same limited resource, harming both. Predation involves a predator species feeding on a prey species. Parasitism benefits the parasite species while harming the host species. Mutualism benefits both species involved. Commensalism benefits one species while not affecting the other. Over time, coevolution can lead to adaptations that reduce harm or improve benefits of interactions between species.
Principles of ecology
Ecology is the scientific study of interactions between organisms and their environment. The components of ecology include abiotic (non-living) factors like temperature and biotic (living) factors like other organisms. A niche describes an organism's role and interactions within its ecosystem, including how it meets its needs. Relationships between organisms in an ecosystem can be symbiotic like mutualism, or involve one organism benefiting more than the other like parasitism or commensalism. Natural selection leads to evolution as organisms with traits better suited to their environment are more likely to survive and pass on those traits, changing the gene frequency in a population over time. Speciation occurs when reproductive isolation splits one species into two distinct species.
Biosphere concept 1st sem ecg 101
This presentations is about the concept of biosphere and its habitats, how it is useful in our life.
biodiversity indices ppt.pptx
Biodiversity indices provide mathematical measures of diversity in communities. They quantify species richness, evenness, dominance, and incorporate both the number of species and their abundances. Common indices include Simpson's index, Shannon-Wiener index, and Evenness index. They are used to measure diversity at different spatial scales like alpha, beta, and gamma diversity. The Index of Biotic Integrity also synthesizes biological data to evaluate biological condition and integrity of aquatic ecosystems based on fish communities and metrics.
Restoration ecology
Restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. It involves improving ecosystem structure and functions to emulate the original, indigenous ecosystem. Approaches include rehabilitation, reclamation, re-creation, and enhancement. The ultimate goal is to enhance ecosystem functioning through increasing nutrient cycling, productivity, and trophic interactions. Successful restoration also requires addressing issues like degraded soil and hydrology. Many restoration efforts aim to restore critical habitats for endangered species or improve water quality in degraded rivers and lakes. Large-scale examples in India include programs to restore the Ganges and Yamuna rivers through reducing pollution and improving sanitation.
ecology concepts and its types
Ecological concepts are introduced and described in the document. The document discusses 7 key ecological concepts:
1) Levels of biological organization ranging from genes to landscapes.
2) The definition of native species and their importance in natural ecosystems.
3) The concept of keystone species that have disproportionate influence on ecosystems.
4) The concept of population viability and extinction thresholds related to amount of habitat.
5) Ecological resilience and the ability of ecosystems to withstand disturbance and return to stability.
6) Disturbances as events that cause changes to ecological systems, both natural and human-induced.
7) Connectivity and fragmentation, and their effects on organism movement between habitat patches.

Intermediate level of disturbance hypothesis (idh)
The document discusses the intermediate disturbance hypothesis (IDH), which proposes that diversity peaks at intermediate levels of disturbance, not in completely stable or unstable systems. It explains that high disturbance favors only good colonists, lowering diversity, while low disturbance allows competitive exclusion of all but a few dominant species. Intermediate disturbance maintains the highest diversity as both competitive and colonizing species can coexist. Examples provided are rainforests maintained by storms and coral reefs maintained by hurricanes.

Coral Reefs: Biodiversity and Beauty at Risk
Coral reefs are the largest structures built by living organisms and are home to 25% of ocean species, yet they are at severe risk. Coral reefs provide many benefits like fisheries, shoreline protection, tourism, and medicines, valued at $233 billion to $1.3 trillion annually. However, threats from overfishing, pollution, disease, bleaching due to warming oceans, and ocean acidification have already damaged many reefs and are projected to severely damage most reefs by 2050 if issues are not addressed.
How Did Scientists discover the properties of electrons
J.J. Thomson discovered electrons through his experiments with cathode ray tubes in 1897. He observed that something was moving from the cathode to the anode, even through a vacuum. To determine if these particles carried an electrical charge, Thomson passed cathode rays through an electric field. He found that the particles were deflected towards the positive plate, indicating they were negatively charged particles. This led Thomson to conclude that the particles, which he named "corpuscles," were subatomic constituents within atoms that could be broken off, contradicting prevailing theories that atoms were indivisible. His discovery of electrons and their negative charge was a major breakthrough in understanding atomic structure.

Brief introduction to chemistry I
This document provides an introduction to basic chemistry concepts. It defines key terms like molecule, atom, element, and compound. It explains that atoms are made up of protons, neutrons, and electrons. The number of protons determines the element, and differences in neutrons create isotopes. Electrons orbit the nucleus, held together by electrostatic attraction between protons and electrons. Common elements in the human body are identified by mass and atomic proportion. Atoms differ in size based on their number of protons and neutrons. This influences their chemical properties and reactivity.
Mark McGinley Story
Mark McGinley was born in Corpus Christi, Texas and spent his early childhood in small towns in Texas, where he developed an interest in biology exploring the countryside. In 6th grade, he moved to Australia and lived in Melbourne and Sydney for several years before returning to Thousand Oaks, California for high school. He then studied zoology at the University of California, Santa Barbara, where he conducted undergraduate research that resulted in a publication. He went on to complete his M.S. at Kansas State University and Ph.D. at the University of Utah, conducting research assistantships in Colorado and Arizona along the way.
Fires & wolves yellowstone
- Yellowstone National Park was established in 1872 and covers 3,472 square miles across Wyoming, Montana and Idaho.
- In the late 1980s, a large wildfire burned over 790,000 acres in the park. This opened up the landscape and allowed new plant growth.
- Gray wolves were reintroduced to Yellowstone between 1995-1997 after being extinct in the park for 70 years. Their reintroduction led to a trophic cascade that benefited various plant and animal species.
Indigenous people of east malaysia
The document provides information on indigenous peoples of East Malaysia, including the Dayaks, Ibans, Bidayuh, Kadazans, Penan and their traditions and lifestyles. It discusses how the Dayaks were historically known for headhunting but have since abandoned the practice. It describes the various ethnic groups' traditional living arrangements, religions, occupations including farming, and clothing. It also addresses how their ways of life have modernized over time.
History of east malaysia
The document provides a history of East Malaysia, focusing on the Sultanates of Brunei and Sulu that ruled over the region in the 15th-17th centuries. It then discusses the arrival of the British in Sarawak in 1838 and their establishment of the White Rajah dynasty to rule Sarawak. For North Borneo, it outlines the involvement of American and German traders in the 19th century and the founding of the British North Borneo Company. It concludes with Japan's occupation of both regions during World War II and their formation as the states of Sabah and Sarawak upon joining Malaysia in 1963.
Indigenous peoples of malaysia
This document provides an overview of the Indigenous peoples of Malaysia known as the Orang Asli. It describes the 3 main groups of Orang Asli - the Semang, Senoi, and Proto-Malay - and notes their different historical migrations and languages. The lifestyle and traditional livelihoods of the Orang Asli are discussed, including effects of British colonization, slavery, and the Malayan Emergency which led to policies of resettlement. Today, the Orang Asli population faces high rates of poverty and challenges to their land and cultural rights.
Cop 19
The document discusses the United Nations Framework Convention on Climate Change (UNFCCC). It was created in 1992 at the Rio Earth Summit to stabilize greenhouse gas concentrations and prevent dangerous anthropogenic interference with the climate system. Nearly every country is party to the UNFCCC, which meets annually to assess climate change progress. The Kyoto Protocol was adopted under the UNFCCC in 1997 and established emissions reduction obligations for developed countries. The goal of the UNFCCC process is for universal participation to efficiently limit future global warming below 2.0°C through a new legally binding climate agreement.
Human population growth
This document discusses human population growth trends over time. It notes that the global human population reached 1 billion in 1830, 2 billion in 1930, 3 billion in 1960, 4 billion in 1975, 5 billion in 1987, 6 billion in 1999, and 7 billion in 2011. It also provides estimates of current birth and death rates worldwide. The document then discusses factors that have allowed unprecedented human population growth, such as advances in agriculture, medicine, and public health. It examines some potential problems associated with high population growth, especially in developing countries, including environmental degradation and resource scarcity. Finally, it outlines the demographic transition process and considers predictions for future global population size and stability.
Plate Tectonics II
The document discusses evidence for plate tectonics including measurements over 10 years showing the movement of tectonic plates and geological studies of ocean floor rocks. Volcanoes, earthquakes, and tsunamis are linked to plate tectonic boundaries as plates diverge, converge, or a hot spot rises. Examples include the Hawaiian Islands formed by a hot spot and volcanoes and quakes at the Mid-Atlantic Ridge. Historic quakes like 1989 in San Francisco and tsunamis such as the 2004 Indian Ocean and 2011 Tohoku, Japan events are also summarized.
Plate Tectonics I
This document provides an overview of plate tectonics and the key individuals and discoveries that led to the development of the theory. It discusses Alfred Wegener's idea of continental drift in the early 20th century, which was initially rejected. It then covers the discoveries of the mid-ocean ridge system and magnetic striping of the ocean floor in the 1950s-60s, which provided evidence that the continents are moving and new crust is generated at ocean ridges through seafloor spreading. This led to the acceptance of plate tectonics as a scientific theory to explain geological phenomena.
How Old is Stuff?
The document discusses estimates of the age of the Earth and universe over time. Early estimates based on biblical interpretations placed the Earth's age at around 6000 years. The development of modern geology in the 18th century, led by James Hutton, established that geological processes occurred gradually over long periods, indicating a much older Earth. Radiometric dating techniques now provide precise measurements of billions of years for the Earth, meteorites, and universe based on the decay of radioactive isotopes.
The earth part ii
The document describes the layers that make up the Earth's interior. It discusses the core, mantle, crust, and lithosphere. The core is divided into a solid inner core and liquid outer core. The mantle is below the core and comprises most of the Earth's volume. It is divided into upper and lower mantle. The crust sits atop the mantle and exists in oceanic and continental forms. The lithosphere includes the crust and upper mantle. The document also provides background on the formation of the Earth and different types of rocks.
Coastal Ecosystems
Coastal ecosystems like estuaries, salt marshes, mangroves, and rocky intertidal zones are influenced by gradients in wave exposure and tidal exposure. Experiments by Joe Connell on barnacles in the rocky intertidal showed that distribution patterns are influenced by both abiotic factors like desiccation stress, and biotic interactions like competition. Mangroves have adaptations like aerial roots and pneumatophores that allow them to survive in intertidal soils with low oxygen and high salinity. They provide nurseries for fish and protect coastlines from storms.
Waves
Ocean waves are caused by wind and transfer energy through water, but do not transfer water from place to place. Key characteristics of waves include wavelength, amplitude, height, and period. Wave movement involves an orbital pattern, with energy moving through water in a circular motion. Near shore, waves begin to break as their movement becomes disrupted. Breaking waves can come crashing ashore. Some surfers seek out large storm waves for challenges they present. There is potential to harness wave power as an energy source.
Tides
Tides are caused by the gravitational forces of the moon and sun interacting with Earth's oceans, which creates two bulges of water that result in two high tides and two low tides each day. The changing positions and distances of the moon and sun relative to Earth cause variations in tide heights and times. Spring tides occur during new and full moons when the sun and moon are aligned, producing the highest tides, while neap tides happen when the sun and moon are at right angles, resulting in lower tides.
