,Q1. In a population of white-tailed deer with a stable age distribution, the finite rate
of increase () is 1.12. Assuming a sex ratio of 1:1 and equal survival between sexes,
what is the per capita birth rate per female per year if annual survival is 0.80 and the
population is closed?
A. 0.32
B. 0.64
C. 1.12
D. 0.80
Correct Answer: B. 0.64
Rationale: For a stable population, » = survival + birth rate (for females, since only
females give birth). With =1.12 and survival S=0.80, the per capita birth rate per
individual (both sexes) is - S = 0.32. But question specifies per female, and sex ratio 1:1,
so birth rate per female = 0.32 * 2 = 0.64. Option A is per capita, not per female; C is ; D
is survival.
Why Wrong:
A - This is the per capita birth rate for the whole population, not per female.
C - This is the finite rate of increase, not the birth rate.
D - This is the annual survival rate, not the birth rate.

Q2. Which of the following best describes the principle of 'compensatory mortality' in
wildlife management?
A. Mortality factors act independently and sum to total mortality.
B. Harvest mortality replaces natural mortality when populations are below carrying
capacity.
C. Total mortality is constant regardless of additional mortality sources.
D. Mortality from predation is inversely density-dependent.
Correct Answer: B. Harvest mortality replaces natural mortality when populations
are below carrying capacity.
Rationale: Compensatory mortality suggests that when populations are below carrying
capacity, harvest mortality can replace natural mortality without increasing total
mortality. Option A describes additive mortality. Option C is too absolute; compensatory
only works under certain conditions. Option D refers to density-dependent predation but
not the principle.
Why Wrong:
A - This describes additive mortality, not compensatory.
C - Total mortality is not constant; compensatory mortality only occurs when natural
mortality is reduced.
D - This describes a specific pattern of predation, not the general principle of

Q3. A wildlife biologist uses a habitat suitability index (HSI) model for the
endangered red-cockaded woodpecker, which requires mature pine stands with a
minimum tree density of 50 trees/ha and understory with <30% hardwood cover. A
candidate stand has 45 trees/ha and 25% hardwood cover. Which HSI component(s)
would be limiting?
A. Both tree density and hardwood cover are limiting.
B. Only tree density is limiting.
C. Only hardwood cover is limiting.
D. Neither is limiting; the stand is suitable.
Correct Answer: B. Only tree density is limiting.
Rationale: HSI models often use minimum thresholds. Tree density (45 < 50) is below
threshold, making it limiting. Hardwood cover (25% < 30%) is within suitable range, so
not limiting. Thus only tree density limits suitability. Options A and C are incorrect
because hardwood cover is not below threshold; D is false because tree density is
unsuitable.
Why Wrong:
A - Hardwood cover is below the maximum threshold, not limiting.
C - Hardwood cover is below the maximum threshold, so it is not limiting.
D - Tree density is below the minimum threshold, so the stand is unsuitable.

Q4. A wildlife refuge manager is designing a translocation program for the
endangered San Joaquin kit fox. Which genetic metric is most critical to monitor to
minimize inbreeding depression in the reintroduced population?
A. Allelic diversity
B. Heterozygosity
C. Effective population size (Ne)
D. Fixation index (Fst)
Correct Answer: C. Effective population size (Ne)
Rationale: Effective population size (Ne) directly influences the rate of inbreeding and loss
of genetic diversity. Small Ne leads to inbreeding depression. While heterozygosity and
allelic diversity are outcomes, Ne is a predictive metric that managers can influence
through translocation design. Fst measures differentiation among populations, not within.
