Ecology
The disciplines of ecology, evolution, and ethology are key to understanding how animal populations interact, behave, and change through time. Discover how groups of organisms interact and form habitats, communities, and ecosystems.
How Animal Populations Interact
Populations of animals interact with each other and their environment in a variety of ways. One of the primary interactions a population has with its environment and other populations is due to feeding behavior.

Communities and Ecosystems
Going beyond populations of animals, we find that larger-scale structure can be seen. The understanding of these higher-level components, which include communities and ecosystems, is inseperable from our understanding of the animals that live in them.

Population Growth and Regulation
Populations are groups of individuals belonging to the same species that live in the same region at the same time. Populations, like individual organisms, have unique attributes.

Animals and Their Environment
A first step to understanding individual animals, and in turn populations of animals, is to understand the relationship they have with their environment. The environment in which an animal lives is referred to as its habitat.

What is a Keystone Species?
A keystone species is a species that plays a critical role in maintaining the structure of an ecological community and whose impact on the community is greater than would be expected based on its relative abundance or total biomass.

How Do Species Interact?
Wildlife species interact with each other in numerous, complex ways. Fortunately, we can make some general statements about these interactions.

Animals on the Edge
At the edges of developed areas, where natural habitats meet human habitats, animals are forced to undergo significant changes to survive and adapt. This article looks at what happens to animals in edge habitats and what it means for the future of our wildlands.

A Brief History of Life on Earth
To better understand the animals that inhabit our present-day world, it helps to examine the broad history of life. By grasping how organisms, past and present, have evolved and diversified throughout the history of our planet, we can better appreciate the animals and wildlife that surround us today.

Population Interactions
Populations of animals interact with each other and their environment in a variety of ways. This lesson examines some of the complex ways in which populations of animals influence each other including hebivory, predation, competition, coevolution, and symbiosis.
