Question 1

Which concept describes the minimum area of habitat required for a wildlife population to persist long-term without inbreeding depression?

Accepted Answer

Minimum dynamic area

Answer

Minimum dynamic area refers to the smallest habitat patch that can sustain natural disturbance regimes and support a viable population over time.

Question 2

What is the primary function of a wildlife corridor in fragmented forest landscapes?

Accepted Answer

Facilitating gene flow and movement between habitat patches

Answer

Wildlife corridors connect isolated habitat fragments, allowing animals to disperse, migrate, and interbreed, which maintains genetic diversity and population viability.

Question 3

The edge effect in forest ecology typically results in which of the following?

Accepted Answer

Increased nest predation rates for forest interior birds

Answer

Forest edges expose bird nests to higher predation pressure from edge-adapted predators like raccoons and crows that penetrate into adjacent interior habitat.

Question 4

Which federal law requires the U.S. Fish and Wildlife Service to designate 'critical habitat' for listed species?

Accepted Answer

Endangered Species Act

Answer

The Endangered Species Act of 1973 mandates critical habitat designation to protect areas essential for conservation of threatened and endangered species.

Question 5

Keystone predators influence ecosystem structure primarily by:

Accepted Answer

Regulating prey populations and indirectly shaping vegetation

Answer

Keystone predators exert top-down control on herbivore populations, which in turn affects plant community composition through trophic cascades.
