This document discusses ecosystems and ecological communities through a case study on acorns and their connections. It emphasizes that living things are affected by and affect non-living things through complex relationships. It stresses the importance of understanding ecosystems, including their structure, processes, changes over time, energy flow, complexity, interconnectedness, and keystone species. Students are assigned to read three case studies and answer questions about bison, prairie dogs, wolves, and salmon to further examine these concepts.

Biology - Sea otter mystery
Sea otter populations along the Aleutian Islands are declining for unknown reasons, which could disrupt the local kelp forest ecosystem. Kelp forests provide habitat for many species and food for sea urchins, a prey item of sea otters. If sea otters become extinct, sea urchin populations may rise and overgraze kelp forests, negatively impacting other organisms that rely on kelp for habitat or food.

A brief presentation of the topics 3.3 and 3.4 from the Biology book from Pearson.
Cats and Dogs (Not the Movie) JB
This document analyzes statistics from the ASPCA website comparing outcomes for dogs and cats in animal shelters. On average, 3.9 million dogs and 3.4 million cats enter shelters annually. Dogs have higher adoption (1.4 million) and return to owner (542,000) rates than cats, which have higher euthanasia rates (1.4 million cats vs 1.2 million dogs euthanized). A slightly higher percentage of cats (37%) than dogs (35%) are adopted, while more cats (41%) than dogs (31%) are euthanized. The author suggests cats may face worse outcomes due to perceptions of them being less affectionate than dogs.

Sexual reproduction involves the combination of genetic material from two organisms to create a new organism. It occurs in eukaryotic organisms through processes like meiosis and fertilization. Meiosis involves the halving of chromosomes, while fertilization involves the fusion of two gametes and restoration of the original chromosome number. Evolutionary theories propose that sexual reproduction developed and is maintained because it allows for increased genetic variation through recombination and adaptation to changing environments.
Sect 13.3
1) Producers like plants convert light or chemical energy into food through photosynthesis or chemosynthesis. A food chain shows how matter and energy pass between organisms. A food web shows multiple interconnected food chains in an ecosystem.
2) An energy pyramid displays the available energy at each trophic level. Only about 10% of energy is transferred between levels, so the amount decreases going up the pyramid. This limits the length of food chains.
3) There are more mice than hawks in a grassland because energy transfers inefficiently between trophic levels in food chains, according to the energy pyramid model.

This study examined the distribution and interactions of two corvid species, Cyanocitta stelleri and Alphelocoma californica, in four habitats within Tilden Regional Park near Berkeley, California. The researchers used line transects to measure population densities and played vocalizations to observe aggressive responses. They hypothesized the species would overlap most in oak woodlands and riparian areas due to food sources, and exhibit more intraspecific than interspecific aggression. The findings supported this, with each species predominating in different habitats but co-occurring in oak woodlands and riparian areas. While interspecific behavior was inconclusive, intraspecific aggression was more common, especially among A. californica responding
1307 evolution
This document outlines learning objectives for a course on evolution. It covers key concepts like natural selection, genetic drift, gene flow, and mechanisms of evolution. Specifically, it defines terms, compares types of selection pressure, and explains how evolutionary factors like mutation and population size can influence allele frequencies over time. Hardy-Weinberg equilibrium and examples of natural selection in specific populations are also discussed.
Genetic drift
Genetic drift is a mechanism of evolution that causes changes in allele frequencies in a population due to random sampling of organisms. It is common in small populations and can cause some alleles to become more common or disappear entirely over time. There are two main types of genetic drift: the bottleneck effect, which occurs when a disaster reduces population size, and the founder effect, which happens when a group founds a new population. Both types can lead to new populations becoming genetically distinct from the original population and play a role in evolution and speciation.

The Twisted Tree of Life (tTOL) Awards
This document outlines categories for the "Twisted Tree of Life Awards", which recognizes common misrepresentations and inaccuracies in depictions of evolutionary trees and processes. Category 1 focuses on inaccurate tree representations, such as outdated models of the kingdoms of life that ignore modern evidence. Category 2 examines problematic terminology like "primitive" and "higher/lower". Category 3 critiques misrepresentations of evolutionary processes, including excessive adaptationism. Category 4 notes the common conflation of Darwin and evolution. The document provides examples for each category and concludes that correcting misunderstandings is important.
Energy flow
The document discusses energy flow through ecosystems. It makes three key points:
1) The largest source of energy for ecosystems is the sun. Plants absorb sunlight through photosynthesis which begins the process of energy transfer.
2) Energy and nutrients are passed between organisms as one eats another, forming food chains and webs. Typically only about 10% of energy is transferred between trophic levels, with the rest lost as heat.
3) Population sizes decrease at higher trophic levels due to inefficiencies in energy transfer between levels. Producers at the bottom have the largest populations since they directly absorb solar energy.
Foodwebs
This document provides instructions for an activity to examine interrelationships among plants, animals, and their environment through investigating food webs. The activity will have students find that ecosystems contain multiple overlapping food chains that form food webs, discover that organisms can be both predators and prey, and write a paragraph describing how a food web works by explaining that some animals serve as both predators and prey.
HABITATS - FOOD CHAIN AND FOOD WEB
This document contains learning objectives and activities about habitats, adaptations, survival, food chains, and food webs. It introduces key concepts like herbivores, carnivores, predators, and prey. Examples are given of habitats like savannahs and the Arctic where foxes live. Activities include modeling squirrel competition for food and identifying predators and prey in pictures. Students are asked to define terms, explain why all food chains begin with plants, and consider the effects of removing organisms from a food web.
Theories to Explain the Diversity of Life
This document contains the Theories to Explain the Diversity of Life. Two main theories of evolution i.e. Lamarckism and Darwinism are discussed.
Letter to Editor by Shoaib Ur Rehman
Genomics plays a vital role in agriculture by assisting in the development of better quality living materials, more nutrient rich food, and plant and animal breeds with improved resistance to factors such as disease, frost, pests, heat, drought, and more. As a field of study, genomics helps increase our understanding of genomes and living things at a fundamental level. While great progress has been made, more work remains to fully understand genomes and translate that knowledge into improved cultivars, collections, and a better living world overall.
Mutation and genetic drift
1. Mutation and genetic drift are mechanisms of evolution that introduce genetic variation. Mutation occurs randomly through errors in DNA replication and creates new variations. Genetic drift is changes in allele frequencies that occur by chance in small populations.
2. The bottleneck effect occurs when a catastrophe reduces population size, leaving only a small, random group of survivors with non-representative genetics. Founder effect happens when a small group establishes a new isolated population, resulting in allele frequency changes through genetic drift.
3. Both genetic drift mechanisms reduce genetic variation over time, making populations vulnerable if environments change. Examples are bearded vultures hunted to near extinction and the Amish founding population with increased Ellis-van Creveld syndrome
anthropology lab reports
The four evolutionary forces are natural selection, gene flow, genetic drift, and mutation. Charles Darwin and Alfred Russell Wallace independently developed the theory of evolution by natural selection. Natural selection is the process by which organisms best adapted to their environment tend to survive and pass on their genes more than others. Mutation introduces new genetic variation, while genetic drift and population bottlenecks can cause changes in allele frequencies in small, isolated populations. The evolutionary force that causes the fastest change in gene frequency is natural selection because it can eliminate entire traits from a population. Sickle cell anemia is caused by a mutation in the hemoglobin gene and is maintained in some populations because it provides resistance to malaria.

Hansen.Project2.Wolverines
The US Fish and Wildlife Service has proposed listing the North American wolverine as a threatened species under the Endangered Species Act due to threats from climate change, trapping, and low genetic diversity. Climate change is reducing wolverine habitat and snow cover needed for reproduction. While trapping alone may not threaten wolverines, combined with habitat loss it poses a risk. Low genetic diversity in the US population limits its ability to withstand these threats. The proposal faces opposition from Western states that believe the science is uncertain and wolverines can adapt without federal protection.

This study examined differences in cortical connections of the primary somatosensory cortex (S1) between prairie vole offspring that received high levels of tactile contact from parents (HC offspring) versus low levels of tactile contact (LC offspring). The study found that HC offspring had greater intrinsic connections within S1 compared to LC offspring. Additionally, HC offspring had more restricted ipsilateral connections to other areas, while LC offspring had more widespread connections to parietal and frontal cortex. Finally, LC offspring had broader callosal connections between hemispheres and more labeled callosal neurons than HC offspring. This suggests that natural variations in parental rearing styles involving tactile contact are associated with differences in cortical organization and connectivity.

Over 100,000 dogs and cats are euthanized every year in Texas shelters due to overpopulation issues. Euthanasia causes stress for all staff at animal shelters and veterinary clinics. The document recommends getting involved with local no-kill animal shelters by adopting, fostering, volunteering, or donating to help reduce euthanasia rates.
Hardy – weinberg law
This document provides an overview of the Hardy-Weinberg law in population genetics. It defines the Hardy-Weinberg principle as stating that allele and genotype frequencies will remain constant from one generation to the next in a population where no evolutionary influences are present. The history of the law developed from the work of Hardy in 1908 and Weinberg in 1908 is discussed. The key assumptions required for Hardy-Weinberg equilibrium - including random mating, large population size, no natural selection or gene flow - are outlined. Equations for calculating expected genotype frequencies based on allele frequencies are presented along with an example calculation.

The document discusses the mating process of giant Pacific octopuses named Hazel and Franklin at the Seattle Aquarium. It describes how biologists estimate their ages to be 2.5 to 3 years old based on their weights of 48 lbs and 43 lbs, respectively. It provides details on the unique anatomy of male octopuses, including their specialized third arm called the hectocotylus that is used to deliver spermatophores (packages of sperm) to females during mating. The pair will be used in a Valentine's Day mating display at the aquarium on February 14.
Island biogeography activity procedure
This document provides student instructions for an activity exploring the theory of island biogeography. Students will simulate habitat fragmentation by analyzing how bean "migrants" spread from a main ecosystem to four island habitats of varying sizes and distances. They will conduct five trials, recording the number of beans reaching each island and calculating averages and percentages. The goal is to observe how island characteristics like size and distance affect biodiversity, as measured by the number of migrant beans reaching different islands.

This document summarizes a student research project that studied the evolution and biogeography of stickleback fish armor traits across four watersheds on Vancouver Island, Canada. The students analyzed stickleback populations to explore how gene flow, natural selection, and population loss shape the geographic distribution of body armor morphs. They found variation in armor traits across watersheds that seems to be influenced by factors like gene flow patterns, introduced predators, and lake chemistry. Their results provide insights into how local ecological conditions and evolutionary processes interact to drive phenotypic diversity in these freshwater fish populations.
Extinction ppt student template
The document discusses natural extinction versus accelerated or human-caused extinction. It notes that 99.999% of all species that have ever lived are now extinct, with natural extinction occurring through environmental disturbances, while accelerated extinction is caused by human activities like hunting, agriculture, habitat destruction, pollution, and international trade. It states that the current rate of extinction is 50,000+ species every 5-10 years, and if nothing is done 1/3 of all living things may be lost within 30 years. The document lists characteristics of extinction-prone species and questions if the reader with those traits is doomed.
Ch 8 Island biogeography lab
1) This document contains an activity guiding students through a simulation of island biogeography. It asks students to hypothesize which type of island (large and close, large but far, small but close, small and far) will receive the most immigrants.
2) Students are instructed to record immigration data to each island type over 5 years and calculate averages to determine which island received the highest percentage of total immigrants.
3) The document asks students to analyze whether their original hypothesis was correct based on the results and explain the outcomes of the simulation.
Ch 7 8 ppt 2010 student notes
This document discusses several key concepts related to biological diversity and biogeography:
1. It defines biological evolution as changes in inherited traits over generations and outlines some processes that lead to evolution like mutations, natural selection, genetic drift, and geographic isolation of populations.
2. It discusses factors that influence biodiversity like habitat diversity, species diversity, and environmental conditions. Greater biodiversity is seen in areas with more physically diverse habitats, moderate disturbance, and small environmental variation.
3. It outlines biogeography patterns seen on different continents and islands, explaining how continental drift, isolation, and adaptation to new environments has led to divergent evolution and speciation over time.
Chapter 1-3 Notes
Human activity is affecting the global environment through population growth, industrialization, and unsustainable practices. The document discusses different values of the environment including utilitarian, ecological, aesthetic, moral, and precautionary principles. It also discusses the value of coral reefs and the importance of scientific knowledge through controlled experiments, variables, data collection, and the role of environmental science in areas like the media, politics, and decision making. Environmental systems can change through negative or positive feedback and examples of depletion, growth, or steady state. Natural and human impacts on systems are discussed along with delays in response, residence times, and the environmental unity concept that everything affects everything else in the system.
Ch 13 and 14 student template ppt 2010
This document discusses forests, deforestation, wildlife management, fisheries, and endangered species. It notes that forests are economically and ecologically important but deforestation is a major environmental concern. Deforestation is driven by wood usage, which is predicted to double by 2050, and paper production, which uses 30% of the world's paper despite only 5% of the population. Unsustainable logging and fishing practices have depleted fish and whale populations. International agreements have established protections and regulations for fisheries, whaling, and endangered species to curb overexploitation and prevent extinctions.
Ch 5 ppt
This document discusses biogeochemical cycles, specifically the carbon, nitrogen, and phosphorus cycles. It notes that the carbon cycle involves both gaseous (CO2, CH4) and non-gaseous forms. The nitrogen cycle moves between the atmosphere as N2 gas, into the soil through nitrogen fixation by bacteria, into plants, then back through decay. Phosphorus differs in that it has no gaseous stage and is stored in rocks and soil organic matter, becoming available to plants through microbial conversion to phosphates.

Ch 12 ppt 2010
This document discusses sustainable agriculture and its environmental impacts. It covers topics like soil structure and erosion, sustainable farming practices like crop rotation and cover crops, integrated pest management, causes of desertification, and issues with factory farming. The key goals of sustainable farming are to conserve soil and water resources and minimize pollution. Practices that reduce soil erosion include contour plowing, terracing, shelterbelts, and low- or no-till plowing. Cover crops and crop rotation help maintain soil nutrients and prevent excess nitrogen runoff. Integrated pest management uses a combination of biological, cultural and targeted chemical controls. Desertification is worsened by poor farming, overgrazing, deforestation and climate change.
Island biogeography
This document discusses island biogeography and provides examples of continental and oceanic islands. It describes how continental islands like Great Britain and Borneo have fauna more similar to nearby mainland areas due to past connections, while oceanic islands have fauna that arrived by air/water and is often endemic. It discusses species-area relationships and how larger islands support more species due to lower extinction rates. It summarizes Robert MacArthur and E.O. Wilson's equilibrium theory of island biogeography.
Biogeography
This document provides an overview of biogeography, which is the study of the distribution of species across different regions. It discusses the history of biogeography, with Alfred Russel Wallace seen as the "Father of Biogeography" for his early research. There are three main types of biogeography: historical biogeography focuses on origins and extinctions of taxa; ecological biogeography examines current distributions based on environmental interactions; and conservation biogeography works to protect environments. The document also describes different terrestrial and aquatic biomes across the world, highlighting their defining characteristics, climates, plants, and animals.

An ecosystem is a biological community of interacting organisms and their physical environment, ranging in size from a drop of water to the biosphere. Key characteristics of ecosystems include their structure, processes like energy flow and cycling of elements, and changes over time. Living components interact through food chains and food webs, with trophic levels defining an organism's position. Species also indirectly affect each other through community-level interactions, and keystone species have large impacts. Ecosystem management aims to conserve species by sustaining ecosystem functions.
Evolution week2
The document discusses major geological drivers of evolution including tectonic plate movement, vulcanism, climate change, and meteorite impacts. Tectonic plate movement has caused continental drift and formation of supercontinents like Pangaea, affecting species distributions. Vulcanism causes both local and global climate changes through emission of gases and particles and formation of new land barriers and islands. Climate changes over geological timescales have also impacted evolution. Meteorite impacts have precipitated mass extinctions. These geological forces alter Earth's conditions and drive evolution through large-scale migrations, speciation events, mass extinctions, and adaptive radiations.

Ecosystems - Elementary
This document defines key concepts in ecology including ecosystems, biomes, producers, consumers, decomposers, and abiotic and biotic factors. It describes different ecosystems like deserts, rainforests, oceans, taigas and tundras. Ecosystems must remain balanced, with organisms depending on resources like food, water and shelter. Adaptations help organisms succeed, and predator-prey relationships follow cycles. Food webs showcase energy transfer between trophic levels.
kljasdiouf98734
The document discusses biology and the levels of organization of living things. It explains that biology is the study of living organisms and how they interact with their environment. It describes the hierarchical levels of organization from the biosphere level down to molecules. Key levels include ecosystems, organisms, cells, organelles and molecules. The document also discusses the unity of life based on DNA and how cells are the basic functional units of organisms. It provides examples to illustrate biological concepts like producers and consumers in ecosystems.
"Connected Planet"
The document provides science objectives for 4th grade students related to ecology and interdependence between plants and animals. The objectives include: [1] Describing the interdependence of plants and animals through behaviors, body structures, and life cycles; [2] Tracing the flow of energy through food chains; and [3] Identifying characteristics of organisms. The objectives aim to teach students how plants and animals rely on each other to survive through relationships like predation, competition, and symbiosis.
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.
Succession ppt
This document summarizes key concepts about ecology that were covered in Ms. Walker's biology class. It defines populations and communities, and describes the interdependencies between populations and the factors that influence population growth. Relationships between populations like predator-prey, parasitism, mutualism and commensalism are discussed. Ecological succession is introduced, including primary succession in a previously unoccupied area and secondary succession following a disruption. The document concludes by assigning homework to create a story applying these ecological concepts.
Ecology Review
This document provides an overview of key ecological principles including biotic and abiotic components of ecosystems, energy flow and biogeochemical cycles, populations and their growth limits, food webs, and the interconnectedness of all living and non-living things. It discusses how ecosystems contain producers, consumers, and decomposers that fulfill specific roles, and how energy flows through food chains while materials cycle through biotic and abiotic interactions. The document emphasizes that all populations are regulated by limiting factors and carrying capacity, and that human population growth warrants special concern due to potential environmental impacts.
An Introduction To Zoology
The document provides an introduction to zoology, discussing several key topics:
- Theories of evolution from scientists like Lamarck and Cuvier are summarized, with Darwin's theory of natural selection identified as the most accurate.
- The complex life cycle of the monarch butterfly is used as an example to illustrate different life cycle stages like egg, larva, pupa, and adult.
- Adaptation strategies animals use to survive harsh environments like the desert and polar regions are outlined.
- The process of mitosis and key differences in replication between prokaryotes and eukaryotes are summarized.
- Homeostatic mechanisms that allow animals to maintain stable body conditions are briefly
Chapter4-Systematics.ppt
Linnaeus developed the first hierarchical system for classifying organisms in the 18th century based on observable traits. While useful, it did not reflect evolutionary relationships. Modern systematics aims to classify organisms based on their evolutionary history and common ancestry, as revealed by anatomical similarities, genetic data, and the fossil record. Phylogenetic trees illustrate evolutionary relationships and shared ancestors between modern species and are constantly refined as new evidence emerges.
Unit 8 evolution for moodle
Evolution is the scientific theory that organisms gradually change over generations through natural selection acting on genetic variation. The evidence for evolution includes fossil records showing gradual changes in organisms over time, anatomical similarities between different species, and molecular biological evidence from DNA and protein comparisons. Charles Darwin's theory of natural selection proposed that variations arise in populations, and individuals with traits more suited to their environment will survive and pass on those traits, gradually changing the species over many generations.
Theories of evolution
This document discusses several theories of evolution, including Lamarckism and Darwinism. Lamarckism, proposed by Jean-Baptiste Lamarck in 1809, suggested that acquired traits could be inherited and drive evolution. It proposed mechanisms like use and disuse of organs. Darwinism, proposed by Charles Darwin in 1859, introduced the theory of natural selection and survival of the fittest. It argued that overpopulation leads to struggle for existence, and natural selection favors individuals with traits best suited for their environment, driving evolution over long periods. Later theorists like Weismann introduced ideas like the distinction between somatic and germ-line cells.
Ch 5
The document discusses key concepts around niches and interactions between species in an ecosystem. It defines niche as the role and habitat of a species, including biotic and abiotic factors. It explains that species compete for resources if their niches overlap too much. Specialized species have narrow niches and are more vulnerable to extinction from environmental changes. Convergent evolution and coevolution can cause different species to evolve similar traits to fill similar niches or as they interact and exert selection pressures on each other over time.

AP Bio Ch. 1-3
This document provides an overview of introductory biology and basic chemistry concepts. It discusses the scope of biology, the diversity and unity of life, evolution as biology's unifying theme, the building blocks of matter including atoms and molecules, chemical bonding, inorganic and organic molecules, and the unique properties of water that support life. Key points include that biology studies life at all levels, all organisms share DNA, evolution occurs through natural selection, atoms are made of protons, neutrons and electrons, chemical bonds form molecules, and the polarity and hydrogen bonding of water molecules gives it properties like cohesion, surface tension, and the ability to moderate temperature.
Genomic Insights into bat Senses
This document summarizes research on the molecular ecology of bat senses. It finds that most bat species have lost the ability to detect pheromones through the vomeronasal organ. However, a few bat families have retained intact vomeronasal function, suggesting independent losses of this sense in most bats. Analysis of vomeronasal receptor genes finds only a few intact receptors in bats, rather than expansions, indicating the system does not play a major role in bat communication.

Ch 9 ppt eating lower of the food chain
The document discusses the environmental impacts of eating meat and dairy products, particularly beef and dairy cows. It notes that animal agriculture uses significant amounts of agricultural land, water, and fossil fuels to produce meat and dairy. Specifically, it states that cows alone use 50% of agricultural land but only provide 18% of calories. It also discusses the water, pollution, deforestation, and greenhouse gas impacts of industrial animal agriculture. The document advocates for eating lower on the food chain to reduce these environmental impacts.
Ch 10 ppt
Ecological restoration involves facilitating natural succession to help an ecosystem recover from human disturbance. There are two types of succession - primary succession establishes ecosystems in areas with no prior ecosystem, like retreating glaciers, while secondary succession reestablishes ecosystems following disturbances like fires. Restoration is difficult for lands that have lost organic matter or been subjected to overuse, and there does not appear to be a permanent climax state, as gradual loss of nutrients occurs even in mature ecosystems.
Ch 9 ppt
This document discusses biological productivity and energy flow in ecosystems. It begins by defining biomass as the total amount of organic matter in an ecosystem, which increases through plant and animal growth. It then explains that ecosystems are open to energy flow, with energy entering as food and leaving as heat or being stored. The laws of thermodynamics state that energy is conserved but always moves to less organized states, increasing entropy. Energy flows in one direction and organisms are generally inefficient at utilizing energy for growth.

Ch 7 laws ppt
The Endangered Species Act (ESA) was enacted in 1973 as the most far-reaching law for endangered species preservation passed by any nation. It protects over 1000 animals and provides penalties for harming endangered species or their habitats. The ESA works by listing species, designating critical habitats, developing recovery plans, and reviewing federal agency actions. The Lacey Act, originally passed in 1900, was one of the earliest US laws aimed at wildlife protection and was expanded in 1981 and 1988 to prohibit illegal wildlife trade internationally and domestically. CITES is an international agreement between governments to ensure wildlife trade does not threaten species' survival. It lists species in three appendices based on protection level.
