CONSERVATION FINAL EXAM 2025 WITH 100%
ACCURATE SOLUTIONS
The answer to the single large or several small (SLOSS) debate concerning optmal reserve design is -
✅✅✅CORRECT -Either a single large or several reserves could harbor a greater number of species,
depending on the degree of species nestedness across areas of different sizes.
According to the figure below, the island Isabela - ✅✅✅CORRECT -Harbors fewer native land-bird
species than all the other Galapagos Islands combined, despite the fact that Isabela is larger than the
cumulative area of the other islands.
All of the following statements are consistent with the simple metapopulation model shown in the figure
below, except the rate of - ✅✅✅CORRECT -Colonization is greater than the rate of extinction when
the fraction of patches occupies is above f*.
Habitat fragmentation can lead to all of the following except - ✅✅✅CORRECT -Environmental
Stochasticity
Which of the following would not be expected near the edge of a forest patch compared to the patch
interior? - ✅✅✅CORRECT -Lower abundance and diversity of nonnative species
Dispersal corridors can benefit a species by - ✅✅✅CORRECT -A and B
According to the figure below, the rate of colonization increases as - ✅✅✅CORRECT -Distance from
the mainland decreases.
Which of the following is a key lesson learned from metapopulation models? - ✅✅✅CORRECT -
Reduced dispersal success can cause a metapopulation to become extinct.
According to the figure below, the rate of extinction increases as - ✅✅✅CORRECT -The number of
species present on the island grows
, According to the figure below - ✅✅✅CORRECT -Bryce Canyon is smaller than Olympic National Park
and has lost a greater number of mammal species than Olympic.
Hatcheries can be harmful to wild populations for all of the following reasons, except -
✅✅✅CORRECT -Hatcheries can quickly generate large numbers of individuals.
According to the figure below, restoration is most likely to occur spontaneously and without extensive
human intervention in areas with - ✅✅✅CORRECT -Moderate productivity and moderate stress
Efforts to breed and reintroduce the California condor have cost tens of millions of taxpayer dollars. Why
might these efforts end up being unsuccessful? - ✅✅✅CORRECT -The continued use of lead
ammunition, only recently banned, has caused lead poisoning of many condors.
Zoos have become important players in conservation by - ✅✅✅CORRECT -Engaging in all of the
above activities.
Which of these statements would not provide evidence of the shifting baselines phenomenon? -
✅✅✅CORRECT -Molecular studies revealed that a high amount of genetic diversity persists among
the few remaining Toromiro trees.
A restoration project may seek to - ✅✅✅CORRECT -Achieve any of the above objectives
According to the figure below, restored sites - ✅✅✅CORRECT -provide greater levels of regulating
ecosystem services than degraded sires but lower levels than reference sites.
Capturing sick or injured individuals from the wild, treating them, and releasing them back into the wild
is called - ✅✅✅CORRECT -Rehabilitation
Active intervention is likely needed to restore areas of high productivity and low stress because -
✅✅✅CORRECT -Such conditions could favor the rapid growth of invasive species.
The active removal of pollutants from the environment is called - ✅✅✅CORRECT -Remediation
