Ecology

Adaptation (Biology): Topic Page
The ability to adapt is a fundamental property of life and constitutes a basic difference between living and nonliving matter.
Biological Invasions: Topic Page
The spread of an invasive species into native plant communities and causing environmental harm by developing self-sustaining populations and disrupting the structure and functioning of the system.
Competition: Topic Page
In ecology, the interaction between two or more organisms, or groups of organisms, that use a common resource in short supply.
Ecology: Topic Page
Ecology is the study of the relationships of organisms to their physical environment and to one another.
Ecosystem: Topic Page
In ecology, a unit consisting of living organisms and the environment that they live in.
Endangered Species: Topic Page

Any plant or animal species whose ability to survive and reproduce has been jeopardized by human activities.
Extinction: Topic Page
In biology, the complete disappearance of a species from the planet.
Food Chain: Topic Page
In ecology, a sequence showing the feeding relationships between organisms in a habitat or ecosystem.
Habitat: Topic Page
In ecology, the localized environment in which an organism lives, and which provides for all (or almost all) of its needs.

Biodiversity: Topic Page
Measure of the variety of the Earth's animal, plant, and microbial species, of genetic differences within species, and of the ecosystems that support those species.
Conservation: Topic Page
In the life sciences, action taken to protect and preserve the natural world, usually from pollution, overexploitation, and other harmful features of human activity.
Endangered Species: Topic Page

Any plant or animal species whose ability to survive and reproduce has been jeopardized by human activities.
Environmentalism: Topic Page
Movement to protect the quality and continuity of life through conservation of natural resources, prevention of pollution, and control of land use.
Pollution: Topic Page
Contamination of the environment as a result of human activities. The term pollution refers primarily to the fouling of air, water, and land by wastes (see air pollution; water pollution; solid waste).
Smog: Topic Page
[smoke+fog], dense, visible air pollution. Smog is commonly of two types.
Wildlife Refuge: Topic Page
An area of land or of land and water set aside and maintained, usually by government or private organization, for the preservation and protection of one or more species of wildlife.

Animal: Topic Page
Member of the kingdom Animalia, one of the major categories of living things, the science of which is zoology.
Mammal: Topic Page
An animal of the highest class of vertebrates, the Mammalia. The female has mammary glands, which secrete milk for the nourishment of the young after birth.
Nest: Topic Page

Place chosen or constructed by a bird or other animal for incubation of eggs, hibernation, and shelter.
Reproduction: Topic Page
In biology, the process by which a living organism produces other organisms more or less similar to itself. The ways in which species reproduce differ, but the two main methods are by asexual reproduction and sexual reproduction.
Zoology: Topic Page
The branch of biology concerned with the study of animal life.

Gerald Durrell (1925-1995): Topic Page
British zoologist, traveller, writer, and broadcaster, born in Jamshedpur, E India, the brother of Lawrence Durrell.
Dian Fossey (1932-1985): Topic Page
American zoologist who conducted extensive studies of mountain gorillas in Rwanda. Her research brought about a new understanding of the behavior and habitat of the gorilla and supported conservation efforts in Africa.
Ernst Haeckel (1834-1919): Topic Page

German zoologist well known for his genealogical trees of living organisms and for his early support of Darwin's ideas on evolution.
Alfred Kinsey (1894-1956): Topic Page

US zoologist; director of noted survey of human sex behaviour; published Sexual Behavior in the Human Male (`The Kinsey Report') (1948) and Sexual Behavior in the Human Female (1953).
Konrad Lorenz (1903-1989): Topic Page

Austrian zoologist who is generally considered to be the founder of modern ethology.
Élie Metchnikoff (1845-1916): Topic Page

Russian zoologist and immunologist who was a pioneer of cellular immunology and shared the Nobel Prize for Physiology or Medicine in 1908 with Paul Ehrlich for the discovery of the innate immune response.

Rachel Carson (1907-1964): Topic Page
American environmentalist and writer whose best-known work, Silent Spring (1962), condemns the use of pesticides hazardous to wildlife.
John Muir (1838-1914): Topic Page

Explorer, naturalist, and conservationist, born in Dunbar, East Lothian, E Scotland, UK.
