Exploring the Microhabitats of Marsupial Frogs- a Study of the Fo
This document is a senior independent study thesis that explores the habitat selection of the marsupial frog Flectonotus fitzgeraldi within populations of the plant Xanthosoma jacquinii in Tobago. The study examines environmental variables, plant morphology, and aquatic variables of phytotelm habitats to better define the ecological niche of F. fitzgeraldi. A multiple logistic regression found that water depth was the only significant predictor of frog occupancy. This suggests the species has a broad ecological niche allowing it to occupy various phytotelm habitats as long as an adequate water supply is present.
Sharing Space, Realistically
The document discusses how humans and other carnivorous species can coexist on Earth. It summarizes a recent study that looked at how factors like human behaviors and development can be changed to reduce aggression when humans and animals encounter each other. The study found that both humans and animals have an inherent ability to adapt to each other and that focusing on reducing conflict, rather than eliminating it, is the best approach for conservation.
Community Ecology
Community ecology examines the distribution, abundance, interactions and dynamics of populations within an ecosystem. It studies patterns such as species richness, productivity and food web structure, as well as processes like predator-prey relationships, succession and community assembly across space and time. Some key concepts in community ecology include species richness, productivity, food webs, succession, and predator-prey relationships.
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.
Ecological niche
This document discusses the concept of ecological niche and its types. It defines ecological niche as the role of a species in its community or ecosystem, including biotic and abiotic factors like food availability, temperature, and competition. There are two main types of niche: the fundamental niche, which is the total suitable environmental range without competition or predation, and the realized niche, which is the part of the fundamental niche a species actually occupies. An example given is the ecological niche of the dung beetle, which consumes dung, stores it to lay eggs, and aerates soil, playing an important role in its environment.
Ecology: Interspecific Competition
This document discusses interspecific competition, which involves two or more species competing for a common, limited resource. It can take two forms: exploitation, where one species uses up the resource leaving none for others; and interference, where one species prevents others from accessing the resource. The document then describes six types of interspecific interactions defined by Thomas Schoener: consumption competition over consuming a shared resource; preemptive competition over occupying space; overgrowth competition by one species growing over another; chemical competition using toxins to inhibit other species; territorial competition over defending space; and encounter competition where meetings negatively impact species. Examples are provided for each type of competition.
Review question chap5
This document contains a student's responses to review questions about chapter 5. It lists examples of predator-prey relationships including a snake and chicken, penguin and fish, lion and zebra, frogs and insects, and an eagle and mouse. It defines the difference between an ecosystem and a community, with an ecosystem including both the living community and abiotic environment. Humans raising cattle for food is described as a form of predation but also potentially a mutualistic relationship. Examples are given of organisms that are herbivores, carnivores, and omnivores. The different trophic levels in an ecosystem are outlined as producers, primary consumers, secondary consumers, carnivores that eat carnivores, and
factors influencing the structure of communities
The structure of ecological communities is influenced by various factors, including the fundamental and realized niches of species, species interactions, and environmental conditions. Species interactions within communities can be direct, such as competition, or indirect, mediated through other species in a food web. Both bottom-up and top-down controls influence population abundances across trophic levels. Environmental gradients and heterogeneity impact species distributions and community diversity through variations in stress tolerance and competition for resources.

Ecology is the scientific study of the relationships between living organisms and their environment. It includes the study of ecosystems, communities, populations, and individual organisms. Some key areas of ecology include ecosystem ecology, behavioral ecology, community ecology, molecular ecology, human ecology, and metapopulation ecology. Metapopulation ecology examines population dynamics across patches within a landscape. Community ecology studies the interactions between species that coexist in a geographic area. Molecular ecology uses genetic techniques to study evolutionary and ecological questions.
Panjami lesson plan 8
The document discusses different types of ecological interactions that occur in nature such as predation, parasitism, competition, mutualism, and commensalism. Predation benefits one organism while harming the other, such as a tiger eating a deer. Parasitism also benefits one organism, the parasite, while harming the host. Competition can initially harm both organisms as they compete for resources, but eventually benefits the stronger organism. Mutualism provides benefits to both organisms, like flowers and butterflies. Commensalism benefits one organism without affecting the other, like mango trees providing shelter for vanda plants. These ecological interactions help maintain balance in ecosystems.
Sect 14.1&2
An ecosystem consists of all the organisms living in an area along with the physical components of the environment. A population is a group of the same species that lives in the same ecosystem, while a community includes all the populations in an ecosystem. Limiting factors like food and water usually have the greatest effect on population size by restricting its growth and determining the ecosystem's carrying capacity, which is the maximum population it can sustain.
ENVI 6 community ecology FINAL
This document discusses community ecology and the interactions between species within a community. It defines a community as all the populations inhabiting the same area and interacting with each other and the environment. Relationships between species can include symbiotic relationships like mutualism, commensalism, parasitism, and others. Ecological succession is also discussed, including primary and secondary succession, pioneer species, and climax communities.
Keystone species
This document defines and provides examples of keystone species. It introduces the concept of the keystone species, which was established in 1969 by Robert T. Paine, and provides starfish and mussels as the original keystone predator and prey. Keystone species have a disproportionate impact on their environment relative to their abundance and play a critical role in maintaining ecosystem structure. The document then provides examples of different types of keystone species, including herbivores like elephants in African savannas, mutualists like hummingbirds and plants in Patagonia, and predators like starfish that control mussel and barnacle populations. It concludes by stating keystone species are integral to ecosystems and their conservation is essential for ecosystem maintenance and restoration.
Ecological interactions
This document discusses different types of ecological interactions between organisms including predation, parasitism, competition, mutualism, and commensalism. Predation benefits the predator but harms the prey, while parasitism benefits the parasite but harms the host. Competition is initially harmful to both organisms but eventually benefits the stronger competitor. Mutualism benefits both organisms, like flowers and butterflies. Commensalism benefits one organism without affecting the other, such as mango trees and vanda orchids.
Ecological relationship
This document discusses different types of ecological relationships between organisms including competition, predation, herbivory, and symbiosis. Competition occurs when organisms require the same limited resources. Predation is when one organism feeds on another. Herbivory describes a primary consumer feeding on a producer or another consumer. Symbiosis refers to long-term interactions where at least one organism benefits, and can be mutualism, commensalism, or parasitism.
Ecosystems โ interactions pdf
Ecosystems include all populations in an area and everything that affects them. Populations interact with their environment through limiting factors that control their size and carrying capacity. Communities consist of all species in an area that interact through competition for resources, predator-prey relationships, and adaptations like camouflage or group behavior. Symbiotic relationships involve close associations between species that can be mutually beneficial, benefit one species, or involve parasitism.
Interactions in Ecosystems ch 14
This document provides information about ecological interactions and succession for a biology class. It includes key concepts about habitats and niches, different types of ecological interactions like competition, predation, and symbiosis. It also discusses population ecology, including population growth patterns, limiting factors, and carrying capacity. Succession is introduced as the process of ecological change in a community over time following a disturbance. Students are assigned to take notes on the chapter, learn about niches from a video, and complete a multiple choice quiz as homework.
Ecological Concepts of Integrated Pest Management
Ecology involves the scientific study of living organisms and their interactions with each other and their environments. It examines how organisms grow, reproduce, interact as predators, parasites or competitors, die out, and evolve or adapt to changing climates and environments. Key concepts in ecology include species, population dynamics, communities, guilds, trophic pyramids, nutrient cycling, succession, stability, productivity, and biodiversity.

1) The document discusses key concepts in ecology including producers, consumers, food chains, and symbiotic relationships.
2) Producers such as plants use photosynthesis to obtain energy from the sun, while some use chemosynthesis, and consumers obtain energy by eating producers or other consumers.
3) Symbiotic relationships include mutualism, commensalism, and parasitism, and an organism's niche describes how it finds resources and avoids threats in its environment.
Unit 3 interactions
This document discusses the concepts of competitive exclusion, niches, and resource partitioning. It explains that competitive exclusion occurs when one species outcompetes another for the same limited resources and drives it to extinction. Species can coexist if they have different niches or use different resources - a concept known as resource partitioning. The niche of a species is defined as its ecological role and use of resources and conditions. The competitive exclusion principle proposes that species with identical niches cannot coexist indefinitely, so coexisting species will have differentiated niches or use different portions of the available resources.
Living things in their environment
This document discusses environmental factors and how organisms adapt to their environments. It defines ecological factors as characteristics of the environment that affect living things, and adaptations as how organisms evolve to survive in specific environments, including morphological, physiological, and behavioral adaptations. It provides examples of adaptations to conditions like water scarcity, temperature changes, sunlight, salt concentration, lack of oxygen, and lack of food. The document also discusses populations as groups of the same species that inhabit the same area and reproduce together. It describes population dynamics, including biotic potential and population growth strategies. Finally, it defines communities as sets of populations that live together in the same habitat, and discusses diversity, ecological succession, and relationships within communities.
Population and Community
This document defines key population and community ecology concepts. It discusses [1] what a population is, factors that affect population size, density, and distribution. [2] Population growth is influenced by natality, mortality, immigration, emigration, and environmental resistance. Carrying capacity is the maximum population size an environment can sustain. [3] Communities are formed by populations interacting in an area. Relationships like predation, competition, and symbiosis shape community structure. Producers, consumers, and decomposers fill different roles. Habitats provide resources while niches define an organism's function. Energy and nutrients flow through food chains and webs.
Ecological niche
1) An ecological niche refers to how a species interacts with other species and its physical environment to obtain resources like food and shelter.
2) The principle of competitive exclusion states that two species cannot coexist indefinitely if they utilize the same limiting resources in the same habitat.
3) Species can reduce niche overlap through mechanisms like habitat segregation along dimensions like feeding height, behavior, and nesting times to avoid direct competition.
Modes of resource use
The document outlines four distinct modes of resource use throughout human history:
1) Hunting-gathering - Societies depended on human and animal muscle power to fulfill subsistence needs from naturally available resources. Social groups were small and kin-based with minimal division of labor. Ecological impact was minimal.
2) Pastoralism - The domestication of animals allowed for flexibility in habitat use. Nomadic pastoral groups created greater resource flows over larger distances and exchanged materials with settled groups. Private property emerged but land was still held communally. Pastoralism contributed somewhat to overgrazing and ecological degradation.
3) Settled cultivation - Agriculture became more significant in moderate rainfall areas. Settlements grew larger
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.
Lesson 24 ecological niche
1) An ecological niche refers to the function a species carries out in its habitat through its use of resources and interactions with other community components.
2) If two species occupy the same exact ecological niche, competition will occur until one species dominates.
3) All species that live in the same habitat have some differences in their niches that allow them to avoid competition, even if aspects of their niches overlap.
Lesson 26 relationship between species
Intraspecific relationships are those between members of the same species and can include cooperation or competition. Interspecific relationships are between different species and can be favorable, harmful, or neutral. Examples of interspecific relationships include competition, predation, parasitism, mutualism, symbiosis, commensalism, and inquilinism. Predation benefits the predator species and harms the prey species. Parasitism also benefits one species, called the parasite, and harms the other, called the host. Mutualism provides benefits to both species involved in the relationship.
Ecology
The document discusses key concepts in ecology including ecosystems, biodiversity, populations, and niches. It defines ecology as the scientific study of the distributions, abundance, and relations of organisms and their interactions. An ecosystem is described as the unique network of animal and plant species that depend on each other to sustain life through their interactions. Biodiversity encompasses all varieties of life from genes to ecosystems at different biological levels.
Art research for art
The Dodo was a flightless bird that was endemic to the island of Mauritius. It stood about 1 meter tall and weighed between 10-18 kg. Its exact appearance is uncertain as it is only known from 17th century drawings, paintings, and accounts. It is believed to have had brownish-grey plumage, yellow feet, a tufted tail, and a grey naked head with a black, yellow, and green beak. It became extinct in the late 17th century due to hunting and destruction of habitat by humans and invasive species. One account from 1598 provides a description of the Dodo.

Animal domestication in geographic perspective kay anderson
This document discusses perspectives on animal domestication from a geographic and cultural perspective. It summarizes the work of earlier scholars like Shaler and Sauer who viewed domestication as a cultural advance driven by human rationality and agency that separated humans from animals and led to civilization. However, more recent scholars have challenged this view, arguing that factors like fragile human ecosystems and mutual relationships between humans and animals also drove domestication. The document examines debates around the origins and causes of domestication and whether it was primarily a cultural or ecological phenomenon.

This document discusses the role of large terrestrial carnivores in maintaining healthy ecosystems. It begins with a brief history of trophic cascade research, highlighting seminal studies by Paine, Estes, and Terborgh that demonstrated top-down regulation of ecosystems by keystone predators like starfish, sea otters, and big cats. It then focuses on research in North America showing that removal of large predators like wolves has allowed herbivore populations to increase unchecked, degrading habitats by over-browsing vegetation and reducing tree recruitment. Studies in places like Yellowstone, Zion, and Banff National Parks provide evidence that wolf reintroduction helps restore plant communities by suppressing deer and elk numbers.

Environmental ethics calio & flores
The document discusses the concepts of environmental ethics and ecology. It defines environmental ethics as the study of humans' moral obligation to preserve the natural environment and order. It discusses the theory of moral extensionism, which argues that natural entities have intrinsic value beyond their usefulness to humans. The document also defines ecology as the study of organism-environment interactions and interrelations. It provides examples of climatic, chemical, and biological environmental conditions. Finally, it discusses humans' relationship with nature and technology's impacts on degrading the environment.
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.

It deals with how organisms live in their environments and interact with biotic factors like other living things as well as abiotic factors such as climate. Ecosystems form through the complex interactions between biotic and abiotic components, with energy flowing in one direction and biogeochemical cycles regulating chemicals. Ecology has many applications and branches including applied ecology, population ecology, limnology, and human ecology.
Histroy of ecology
1) Ecology developed as a field of study over thousands of years, with early concepts found in ancient Hindu and Greek texts from 600 BC and 370 BC.
2) In the 18th and 19th centuries, key thinkers like Linnaeus, Darwin, and Humboldt made important contributions relating to biogeography, natural selection, and interactions between organisms and their environment.
3) The term "ecology" was coined by Ernst Haeckel in 1866, and the field expanded in the 20th century with pioneering work by Shelford, Elton, Tansley, and Eugene Odum on concepts like food webs, ecosystems, and ecosystem ecology.

An ecosystem consists of all the organisms and physical environment that interact in a specific area. Early Greek philosophers made early observations on natural history and ecosystems. Concepts like food chains and species relationships were developed starting in the 1700s. The term "ecology" was coined by Ernst Haeckel in 1866 to describe the interactions between organisms and their environment. Ecology became an important field in the 1960s and 1970s as the environmental movement grew.
2 - Una breve historia de la sostenibilidad.pdf
The document provides a history of sustainability from ancient times to the modern environmental movement. It discusses how early thinkers like Malthus, Thoreau, and Marsh questioned beliefs around unlimited growth. The science of ecology developed in the 20th century and viewed nature as interconnected systems rather than isolated resources. The environmental movement emerged in the 1960s-70s sparked by books like Silent Spring and events like the first Earth Day. New laws in the 1970s protected the environment and addressed issues like hazardous waste sites.

Carolus Linnaeus developed the hierarchical system for classifying organisms that is still used today, assigning each a binomial Latin name. Thomas Malthus argued that populations can grow faster than resources. Charles Lyell collected evidence supporting James Hutton's theory of gradual geological change and influenced Darwin's work. Gregor Mendel's experiments with pea plants established the laws of heredity and supported Darwin's theory of natural selection. Jean Baptiste de Lamarck and Charles Darwin both proposed theories of evolution, though Darwin's theory of evolution by natural selection through variation and heredity became widely accepted.
History of Ecology
The document traces the history and development of ecology from its early roots in the 18th century through present day. It discusses key figures like Carl Linnaeus, Alexander von Humboldt, Charles Darwin, and others and their contributions to establishing ecology as a recognized scientific discipline. Major developments included the establishment of biogeography, the ecosystem concept, succession theory, and recognition of humans as an ecological factor. Conservation efforts also stemmed from the growing field of ecology.
Animal Systematics Lecture 1
This document provides an overview of taxonomy and the classification of life. It discusses the early development of taxonomy from Aristotle through Linnaeus and the establishment of the binomial nomenclature system. It also describes how Darwin's theory of evolution influenced taxonomy by establishing that classification should reflect evolutionary relationships and shared ancestry. Modern taxonomy incorporates various lines of evidence including morphology, embryology, biochemistry, and molecular data to reconstruct evolutionary history and classify organisms appropriately.
Taxonomy n Systematics
This document provides an overview of the history and development of taxonomy, the science of classifying living organisms. It discusses how early taxonomists like Aristotle and Linnaeus grouped organisms based on visible characteristics. Charles Darwin later established that taxonomy should reflect evolutionary relationships and shared ancestry. The document also outlines the major kingdoms and domains proposed by scientists over time to classify the diversity of life, from the original plant and animal kingdoms to the current three domain system of bacteria, archaea, and eukarya. Molecular evidence now supports or refines previous taxonomic classifications.

The biofloc is a protein-rich aggregate of organic material and microorganisms that forms in aquaculture systems. Biofloc technology maintains water quality and provides nutrients by balancing carbon and nitrogen through the addition of carbon sources like molasses. It has been successfully used in tilapia and shrimp farming and allows for high stocking densities through natural water treatment. Key factors that must be controlled include carbon to nitrogen ratio, dissolved oxygen, pH, and ammonia, nitrite and nitrate levels.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Ecological niche
- 3. ๏The match of a species to a specific environmental condition DEFINITION
- 4. ๏The relational position of a species or population in an ecosystem.
- 6. ๏The abiotic or physical environment is also part of the niche because it influences how populations affect, and are affected by, resources and enemies NICHE & ABIOTIC FACTORS
- 8. ๏ Hutchinson described two forms of niche. ๏ The fundamental niche focused on the conditions in which a species could exist with no ecological interactions. ๏ The realized niche, in contrast, considered the population's existence in the presence of interactions, or competition. TYPES
- 11. ๏ The term was coined by the naturalist Roswell Hill Johnson but Joseph Grinnell was probably the first to use it in a research program in 1917, in his paper "The niche relationships of the California Thrasher". HISTORY
- 12. ๏ also called Gause's Principle, states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. ... This principle means: no two species can sustain coexistence if they occupy the same niche. COMPETITIVE EXCLUSION PRINCIPLE
- 14. ๏Three parts of a niche include food type, abiotic conditions, and behavior. PARTS OF NICHE
- 16. ๏ Ecological niches are important for a given place because they allow different species to live together, usually without competition. Each species knows its position in both the ecosystem and the food chain. IMPORTANCE
- 18. ๏ The natural world is filled with plants and animals, each with their own special job or niche. ๏ A niche is the role played by an organism in the natural world. ๏ Animals and plants all have a special role in making natural communities work and stay healthy. ๏ Some animals, like the pileated woodpecker, are insect eaters. ROLE
- 20. ๏ Like other species, the fundamental niche of humans is bounded by their biological tolerance of extremes of environmental conditions. ๏ Humans also manage the ecological constraints of their mutualistic plants and animals such as agricultural cows, pigs, chickens, and plant crops.
