Textbook Question
Chapter 53, Problem 3TYU
Scientific study of the population cycles of the snowshoe hare and its predator, the lynx has revealed that
- (A) predation is the dominant factor affecting prey population cycling.
- (B) hares and lynx are so mutually dependent that each species cannot survive without the other.
- (C) both hare and lynx
population sizes are affected mainly by abiotic factors. - (D) the hare population is r-selected and the lynx population is K- selected.

Assume that for a given population of moose, the per-capita birth rate remains constant with population size. However, as the moose population size increases there is a linear increase in the probability of starvation and subsequent mortality due to intraspecific competition.
a) On a single graph, draw the relationship between moose density and the per capita birth and death rates for this population.
b) Assume that the population does not experience competition from other species, nor predation. Write out the equation that would best be used to describe the change in population growth from one time interval to another.
When wolves were returned to Yellowstone National Park in 1995, some of the effects noted were increasing levels of berries available to black bears, stabilization of stream
banks, increased nesting habitat for birds, and increasing beaver numbers as a result of rejuvenating aspen trees. These were later determined to be the results of reduced
numbers and altered feeding behavior of elk as they were preyed upon by the wolves. Given this information, which of the following best describes wolves in Yellowstone National
Park?
A. They are a primary consumer
B. They are an ecosystem engineer
C. They are a foundation species
D. They are a keystone species
E. They are a flagship species
The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals.
1.Explain why the peaks in the predator population occur after those in the prey population.
2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?
