Field studies in ecology often are conducted over many years. Dr. Hadley has studied Yellowstone's ecology for 30 years and its amphibian populations for 20 years. What is the value of long-term studies in ecology for

understanding processses like climate change?

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
