Question 1

Which population estimation method involves capturing, marking, releasing, and then recapturing individuals to estimate total population size?

Accepted Answer

Mark-recapture (Lincoln-Petersen)

Answer

The Lincoln-Petersen mark-recapture method uses the ratio of marked individuals in a second sample to estimate total population size.

Question 2

The concept of 'carrying capacity' (K) in wildlife ecology refers to:

Accepted Answer

The maximum sustainable population size an environment can support

Answer

Carrying capacity (K) is the maximum population size that an environment can sustainably support given available resources.

Question 3

Which type of wildlife corridor is designed to connect large, isolated habitat patches to reduce the effects of habitat fragmentation?

Accepted Answer

Landscape linkage

Answer

Landscape linkages are wildlife corridors designed to connect fragmented habitat patches, allowing species movement and gene flow between populations.

Question 4

Home range analysis in wildlife ecology is BEST described as:

Accepted Answer

The area within which an animal carries out its normal activities

Answer

Home range is defined as the area traversed by an individual during its normal daily activities, excluding unusual movements such as dispersal.

Question 5

In the context of wildlife management, 'maximum sustained yield' (MSY) is the harvest level that:

Accepted Answer

Produces the greatest harvest while keeping the population stable

Answer

MSY is the largest harvest that can be taken continuously without causing long-term population decline, typically occurring at approximately K/2.
