Question 1

Population viability analysis (PVA) is used in wildlife management primarily to:

Accepted Answer

Predict extinction probabilities and evaluate management scenarios for small populations

Answer

PVA uses demographic data and stochastic modeling to estimate the likelihood of population persistence under different management scenarios over time.

Question 2

Which type of wetland provides the most critical breeding habitat for amphibians in eastern North American forests?

Accepted Answer

Isolated seasonal vernal pools without fish

Answer

Vernal pools are temporary, fish-free wetlands that provide amphibians like spotted salamanders and wood frogs safe breeding sites where egg predation by fish is absent.

Question 3

Acoustic monitoring using autonomous recording units (ARUs) is particularly valuable for assessing populations of which wildlife group?

Accepted Answer

Bats and nocturnal songbirds

Answer

ARUs can passively record bat echolocation calls and nocturnal bird vocalizations over extended periods, enabling non-invasive population assessment across large areas.

Question 4

Which disturbance-based management strategy mimics the natural role of fire to maintain savanna and woodland habitats?

Accepted Answer

Prescribed fire application at ecologically appropriate intervals

Answer

Prescribed fire replicates the ecological role of natural fire in maintaining open-canopy savannas and woodlands by controlling woody encroachment and maintaining structural diversity.

Question 5

The concept of 'habitat heterogeneity' suggests that landscapes with diverse habitat types tend to support higher wildlife diversity because:

Accepted Answer

Different species require different resources found in varied habitat conditions

Answer

Habitat heterogeneity provides varied resources, microclimates, and structural conditions that meet the diverse needs of many species, supporting greater overall biodiversity.
