|
With the aid of examples, explain the feeding characteristics of true predators, grazers, parasites and parasitoids.
|
TBD
|
|
|
True predators, grazers and parasites can alter the outcome of competitive interactions that involve their 'prey' populations: discuss this assertion using one example from each category.
|
TBD
|
|
|
Discuss the various ways that plants may 'compensate' for the effects of herbivory.
|
TBD
|
|
|
Predation is 'bad' for the prey that get eaten. Explain why it may be good for those that do not get eaten.
|
TBD
|
|
|
Discuss the pros and cons, in energetic terms, or (i) being a generalist as opposed to a specialist predator, and (ii) being a sit-and-wait predator as opposed to an active forager.
|
TBD
|
|
|
In simple terms, explain why there is an underlying tendency for populations of predators and prey to cycle.
|
TBD
|
|
|
You have data that shows cycles in nature among interacting populations of a true predator, a grazer and a plant. Describe an experimental protocol to determine whether this is a grazer-plant cycle or a preador-grazer cycle.
|
TBD
|
|
|
Define mutual interference and give examples for true predators and parasites. Explain how mutual inteference may dampen inherent population cycles.
|
TBD
|
|
|
Discuss the evidence presented in this chapter that suggests environmental patchiness has an important influencce on predator-prey population dynamics.
|
TBD
|
|
|
With the help of an example, explain why most prey species may be found in communities subject to an intermediate intensity of predation.
|
TBD
