Question 1

What is the term for the phenomenon where species richness on habitat islands increases with island area?

Accepted Answer

Species-area relationship

Answer

The species-area relationship, described by the equation S = cA^z, predicts that larger habitat patches support more species than smaller ones.

Question 2

Riparian buffer zones adjacent to streams primarily benefit wildlife by:

Accepted Answer

Providing shade, food, and cover while filtering agricultural runoff

Answer

Riparian buffers shade streams to maintain cool temperatures, provide mast and invertebrate food sources, offer cover, and intercept sediment and nutrients from adjacent lands.

Question 3

Which habitat management technique is most effective for maintaining early-successional habitat for species like golden-winged warblers?

Accepted Answer

Prescribed fire or mechanical disturbance to set back succession

Answer

Prescribed fire and mechanical treatments like mowing or roller-chopping reset plant succession, creating the shrubby young forest conditions early-successional wildlife require.

Question 4

The biological concept of 'source-sink dynamics' in metapopulation ecology refers to:

Accepted Answer

High-quality habitats producing surplus individuals that supplement declining sink populations

Answer

Source habitats have positive population growth rates and export individuals to sink habitats, where reproduction alone cannot sustain the local population.

Question 5

Snag retention in managed forests is most critical for which wildlife guild?

Accepted Answer

Cavity-nesting birds and mammals dependent on dead wood

Answer

Primary cavity excavators like woodpeckers and secondary cavity users like owls, bluebirds, and flying squirrels depend entirely on standing dead trees for nesting and roosting.
