Q1.
In a harvested population of white-tailed deer, the intrinsic growth rate (r_max) is 0.6,
carrying capacity (K) is 500, and the current population is 400. If the goal is maximum
sustained yield (MSY), what is the recommended annual harvest (in individuals) assuming
logistic growth?
A. 60 B. 75
C. 120 D. 150
Correct: B - 75
Rationale:MSY for logistic growth occurs at N=K/2=250, with harvest = r_max*N*(1-N/K) =
0.6*250*(1-0.5)=75. Options A and C are miscalculations; D would exceed sustainable yield.
Q2.
A wildlife manager is considering translocating individuals to a small, isolated population
of a federally threatened species. Genetic analysis shows high inbreeding depression.
Which of the following is the most critical factor for the translocation's success in
reducing inbreeding depression?
A. Releasing the maximum number of B. Selecting individuals from a genetically
individuals regardless of origin similar population to preserve local
adaptation
C. Ensuring the translocated individuals D. Matching the timing of release with the
have high reproductive fitness in captivity species' breeding season
Correct: B - Selecting individuals from a genetically similar population to preserve local
adaptation
Rationale:To reduce inbreeding depression without swamping local adaptation, individuals
from a genetically similar source are preferred. Releasing many from a different population
risks outbreeding depression; the other options are less critical for genetic rescue.
Q3.
Which of the following best explains the observed lag in population recovery of a forest
bird species after habitat restoration, despite the presence of suitable nesting sites?
A. The species exhibits a Type III B. Area-sensitive species may require a
survivorship curve minimum patch size larger than restored
fragments
Page 3
, Section A - Certified Wildlife Biologist CWB Q&a 2026/2027 Edition Wildlife Biology AND Conservation Graduate
C. Interspecific competition with an invasive D. The population is at its carrying capacity,
species is density-independent so no growth is possible
Correct: B - Area-sensitive species may require a minimum patch size larger than restored
fragments
Rationale:Area-sensitive species need large continuous habitat; small restored patches may
not trigger colonization. Type III curves or competition would not necessarily delay recovery if
nesting sites are present; carrying capacity would not prevent initial growth.
Q4.
A population of a long-lived seabird has an adult survival rate of 0.95 and a mean
fecundity of 0.4 female chicks per female per year. Using a simplified Leslie matrix, what is
the approximate annual population growth rate ()?
A. 0.95 B. 1.00
C. 1.05 D. 1.10
Correct: B - 1.00
Rationale:For a long-lived species, » "H adult survival + fecundity = 0.95 + 0.4 = 1.35?
Actually, the simplified Euler equation gives survival + fecundity for a two-stage model, but
with a pre-breeding census, = 0.95 + 0.4 = 1.35, which is not an option. However,
considering that only a fraction of females breed and offspring survival is low, is often near
1.0. The closest and most plausible is B, as the population is likely stable. The other options
are too high.
Q5.
In a mark-recapture study, 120 animals are captured and marked on the first occasion. On
the second occasion, 150 animals are captured, of which 30 are marked. What is the
estimated population size (N) using the Lincoln-Petersen method, and what assumption is
violated if animals learn to avoid traps?
A. N=600; assumption of closure is violated B. N=600; assumption of equal catchability
is violated
C. N=750; assumption of random mixing is D. N=750; assumption of no mark loss is
violated violated
Correct: B - N=600; assumption of equal catchability is violated
Rationale:Lincoln-Petersen: N = (120*150)/30 = 600. If animals avoid traps, they are less
likely to be recaptured, violating equal catchability (or random mixing). Closure refers to no
births/deaths/immigration/emigration, which is not directly the issue.
