Assume a raptor species exhibits a Type III response to changes in the abundance of rabbits. Which figure below represents the expected relationship between the % of the rabbit population consumed by a raptor as the abundance of rabbits increases?

A

B (correct)

C

D

In which scenario below is predator control most likely to be an effective and justifiable management strategy?

The prey population is near carrying capacity

Research suggests that predators are killing a substantial number of prey that would otherwise survive if predation were reduced (correct)

It is uncertain whether reduced predation would result in higher harvest rates or population sizes of the prey species

It is unlikely the predator population will persist in the managed ecosystem following control efforts

On the figure below, if the population and prey numbers are both within the quadrant represented by the star, what trajectories would you expect for the prey and predator populations?

Predators increase and prey decrease

Predators decrease and prey decrease

Predators increase and prey increase (correct)

Predators decrease and prey increase

Which of the following population growth figures for a predator (red) and prey (blue) species represents a Lotka-Volterra relationship when density-dependent regulation of the prey species is considered?

Long term studies in a region show that the annual density of nesting raptors closely tracks annual variation of the local field mouse population density. When field mice are abundant the density of nesting raptors is high, and when the field mice population is low few raptors nest in the area. What type of response are the raptors exhibiting in responding to changes in prey abundance?

As the dry season approaches in an arid landscape in Africa, river levels start to decrease, which leads to a situation where there are only a few pools of water that attract land animals that need to drink.

Crocodiles in the river tend to congregate in these pools where water is still reasonably deep and where potential prey often come to drink. The behavior of the crocodiles is representative of...
