Summary Introduction

To review:

An experiment to test the maternal manipulation hypothesis for the evolution of viviparity.

Introduction:

The maternal manipulation hypothesis states that pregnant females in viviparous squamate lizards can select optimal temperature for the development of embryo by seeking or avoiding the sun. This type of temperature control is not possible in oviparous lizards which lay eggs in a nest.

Acorn woodpeckers (Melanerpes formicivorus) stash acornsin storage holes they drill in trees. When these woodpeckersbreed, the offspring from previous years often help withparental duties. Activities of these nonbreeding helpers includeincubating eggs and defending stashed acorns. Propose somequestions about the proximate and ultimate causation of thesebehaviors that a behavioral biologist could ask.
Why some animals provide parental care while some other like clams(molluscs),barnacles(crustaceans),many fish do not provide any parental care?
Female parasitoid wasps search for insect hosts in which to lay eggs, and they can often discriminate among individual hosts that are more or less suitable for their offspring. Behavioral ecologists have asked whether or not the wasps’ willingness to lay eggs in less suitable hosts varies with the female’s age. On the basis of life history theory, what pattern of change would you predict? Does life history theory make any other predictions about animal behavior?
