Exam 14: Predation

Some plants may be able to compensate for the loss of leaves to herbivores by increasing the rate of photosynthesis in remaining leaves.

Predators have three general methods of hunting: ambush, ________, and ________.

Qualitative inhibitors

________ mimicry involves a non-toxic species that resembles a toxic species while ________ mimicry is the shared colour pattern of unpalatable or toxic species.

Which of the following is considered a predator?

The functional response is the relationship between the per capita rate of predation and ________.

The ________ functional response depicts a sigmoidal rate of predation.

Use a real or hypothetical example to describe coevolution. What happens when a predator and/or its prey is unable to respond appropriately?

Which of the following is NOT a hunting method used by predators?

________ involves the development of novel adaptations in predator and prey populations in response to advances that make each more successful, either at obtaining prey or evading a predator.

Under the marginal value theorem, when patch quality is equal, what other factor is expected to influence the time a predator spends foraging in a patch?

The change in prey consumed per predator as prey numbers increase is called the predator's

In the Lotka-Volterra models of predator-prey interactions, prey density does not influence predator mortality.

In the Lotka-Volterra equations that represent predator-prey interactions, predators are a source of density-independent mortality for prey.

The concept of ________ energy is the basis for models of optimal foraging.

Some plants are able to attract beneficial insects that act as predators on the herbivores of that plant.

In response to the nonlethal presence of predatory damsel bugs (Nabis), pea aphids (Acyrrhosiphon)did all of the following, EXCEPT
