WILD 301 WILDLIFE EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS
Banning the use of DDT in the U.S. in 1972 did not reverse the decline in peregrine
falcon populations in the nation because most of the bird's habitat had been
profoundly altered by human development. - Answer-False
A population with an estimated annual lambda of 1.96 is: - Answer-Increase 96%
Among the factors listed below, which one's effect is clearly not related to density of
animals: - Answer-Weather events
Paul Errington introduced the idea of a "doomed surplus" in wildlife populations. This
term refers to: - Answer-The proportion of the population that is destined to die
annually from all causes
A basic equation for predicting the number of animals at time t+1 is: - Answer-Nt+1 =
Nt + Bt + It - Dt - Et
We reviewed several habitat selection study "designs" in class. Which design
contrasts areas actually used by an organism to carefully sampled random plots
distributed across the entire study area? - Answer-Used vs. Available Design
Select the best example of a wildlife "population" based on the definition presented
in lecture: - Answer-The bison of the Greater Yellowstone area
What is the ultimate cause of all density-dependent population growth? - Answer-
Resource availability
In a simple predator prey community there are 3000 individual prey animals just prior
to the reproductive season. These animals produce 500 young. After reproduction
200 animals die of starvationand predators kill an additional 200 animals during the
rest of the year. If predation is completely additive what would be the size of the
population at the end of the annual cycle if predators had been removed from the
system - Answer-3300
What is Wildlife? - Answer-All wild and free ranging life forms
Wildlife management definition - Answer-The application of ecological knowledge to
populations of vertebrate animals and their plant and animal associations in a
manner that strikes a balance between the needs of population and needs of people.
How is Ecological Knowledge applied to Management Approaches? - Answer-
Preservation, Direct manipulation, Habitat manipulation
, According to the Public trust document, who owns Wildlife in the U.S.? - Answer-all
Americans
Who is chartered with the role of Managing Wildlife for the Public in the U.S.? -
Answer-agencies for the benefit of the public
Why should we manage and conserve Wildlife? - Answer-Economics, esthetics,
ethics, legal mandates , and maintain ecosystem processes and integrity
When was Market hunting an issue? - Answer-Era of exploitation/eradication from
1960-1920
Which species would be most likely to show a K-Selected Life History strategy? -
Answer-Spotted Owls and California Condors
What are other species that would most likely show a K-Selected Life History
strategy? - Answer-African Elephant and Hump-Backed Whales
In the paper you read on female greater sage grouse (Moynahan et al. 2006), the
author's contrasted the summer survival rates of nesting and non-nesting hens. Their
results showed Nesting Hens were the group with consistently better survival -
Answer-True
What explanation did the authors offer in the paper on female sage grouse
concerning the likely mechanism for the difference in survival between the two
groups of hens? - Answer-Lower predation risk of stationary hens on nests, Lower
detection rates by avian predators, Higher physiological condition of nesting hens.
A biologist can assess habitat quality by measuring the abundance or density of
animals in an area and assume the more abundant the animals the better the quality
of the habitat in the area - Answer-False
A wildlife "source" population generates more frequent emigration than "sink"
populations. - Answer-true
The classic 'logistic equation' describes the influence of density independent
mechanisms or processes on the growth of a population - Answer-false
Modern wildlife professionals no longer advocate the elimination and/or drastic
reduction of one animal species for the benefit of another. - Answer-False
When were season lengths set, "bag" limits, and "buck" laws put into place? -
Answer-Early regulatory management from 1850-1910
When was the Pittman-Robertson fund made? - Answer-1937
When was the Dingell-Johnson fund made? - Answer-1950
How has wildlife management evolved in N. America? - Answer-Regulatory ->Game
-> Non-game -> endangered species -> biodiversity
