2020 Population Dynamics

Question 1

According to “population dynamics and management,” which of the following is true of the harvestable surplus?

a. It is the amount that can be taken by people without reducing the breeding population
b. It is possible because trapping replaces or compensates for some natural mortality that would otherwise occur
c. Harvestable surplus is possible in part because organisms are able to produce more than needed to maintain the population
d. All of the above statements are true

Answer 1

d. All of the above statements are true

Question 2

According to “population dynamics and management’” which of the following is not a factor that influences birth rate?

a. Age when breeding begins
b. Human activities and predation
c. Number of young born per litter
d. Number of times each year that young are born

Answer 2

b. Human activities and predation

Question 3

According to “population dynamics and management,” there are many obvious population variations that occur throughout the year. Identify the statement below that is true about these variations

a. Wildlife populations are generally at their peak in the spring due to lush vegetation, allowing carnivores to have more vegetation to eat
b. Wildlife populations are generally stagnant and do not change much in the spring, summer or fall
c. Wildlife populations are generally at their lowest in the winter due to harsh weather conditions and high competition for scarce resources, coupled with mortality rates.
d. The average lifespan of most wildlife species is around five years, with most deaths occurring during the fall or winter

Answer 3

c. Wildlife populations are generally at their lowest in the winter due to harsh weather conditions and high competition for scarce resources, coupled with mortality rates

Question 4

According to “population dynamics and management,” there are many ways to estimate a wildlife population size. However, most estimates occur from taking a sample. Which statement below is not true of estimating a population on a sample basis?

a. Animals can be counted directly, by sight or by sound
b. Trapping and marking animals in order to estimate a population is expensive and takes a great deal of time so it is not a common practice
c. Antelope are easy to count directly to determine an estimation because they roam freely in open territories
d. All of the above statements are are true

Answer 4

b. Trapping and marking animals in order to estimate a population is expensive and takes a great deal of time so it is not a common practice
