Ecology

The natural history of caribou illustrates why their decline is a critical problem for arctic habitats.

A new informatics system studies the impact of environment on hereditary behaviour in social organisms.

The marsh at Point Pelee National Park provides an important example of wetland habitat, which is seriously threatened by human use. Why are wetlands so essential?

Simulated habitats protect endangered species, raise conservation awareness and bring visitors face to face with exotic and indigenous species they rarely see.

Satellite data from NASA illustrates how different regions impact Earth's metabolism.

Nurse trees and snags are essential to the diversity of forest ecosystems.

Why is the decline of amphibians so important?

Beavers are ecosystem engineers, a key species in building and maintaining new habitats. They alter forest succession and play an important role in establishing new wetlands, enhancing biodiversity.

The beaver is among the most important animal species in North America, both in terms of its historic economic value and its environmental influence. This large rodent has distinctive features and behaviour that qualify it for this role.

While ecology is a fuzzy science with an exception to practically every rule, ecosystems function according to certain principles
