Impact of human disturbance on migratory waterfowl
... Human disturbances can either alter the physical environment or cause changes in an animal’s behavior. The response to human disturbance is at times similar to how animals respond to risk of predation. For waterfowl, hens rely on stored lipids as energy to forage for the protein food sources require ...

17 Ecosystem change and resiliency

Ecological succession is the natural process in which a disturbed area is gradually taken over by a species or groups of species that were not there before. For example, if a volcano erupted and the ...
