Overview: Discovering Ecology
Ecology is the scientific study of the interactions between organisms and the environment These interactions determine the distribution of organisms and their abundance Modern ecology includes observation and experimentation

The Scope of Ecological Research
Ecologists work at levels ranging from individual organisms to the planet

Global Ecology
The biosphere is the global ecosystem, the sum of all the planet’s ecosystems Global ecology examines the influence of energy and materials on organisms across the biosphere

Landscape Ecology

How organisms are physiologically adapted to their environment and how much the environment impacts the distribution of species. Behavioral ecology
How the behavior of an individual...
