- Because the reproductive success of female Hanuman langurs (Semnopithecus entellus) is almost certainly lowered when a newly installed male kills their young infants, selection should favor countermeasures against infanticidal males. In this light, why might already pregnant females mate with a new male soon after a takeover even though they are not ovulating? What significance do you attach to the discovery that when mares are impregnated by stallions at stables away from their home locations, they will also copulate repeatedly with the males in their home stables upon their return?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?In 1993, primatologist Richard Wrangham proposed that "Bonobo hypersexuality appears closely linked to the evolution of female-female alliances. I suggest that these alliances were made possible by relaxed feeding competition." Generate a hypothesis about why Bonobos behave this way.
- Female mimicry by males occurs in many species. For example, in the Broadley’s flat lizard (Platysaurus broadleyi), some males have the brown coloration of females while others are far more colorful (Whiting et al. 2009). Female mimics do secure some matings in the territories of their larger, more colorful rivals. Why are the bigger males (and those of the marine isopod Paracerceis sculpta) ever fooled into tolerating a female mimic? Why do female mimics occur in any species if the mating success of these individuals is lower than that of the bigger territorial males? Don't write from any online source..Which of the following sexual traits is LEAST likely to have evolved due to male-male competition for mates, also known as intraspecific sexual selection?a) Enlarged femurs that an insect uses to kick other malesb) Brushes on the tip of a dragonfly penis used to remove sperm of other malesc) Mate-guarding behavior of a warbler during the female’s fertile periodd) Elongated tails of the male swordtail fish used during courtshipWhat sorts of studies would we undertake in order to confirm that human mating behaviors are truly driven by biological forces, e.g., evolutionary fitness, rather than cultural or societal advantages?
- The fantastic coloration and behavioral displays in the birds of paradise that we watched in class were examples of differential sexual selection driven by: a. Female-female combat b. Male competition c. Female choice d. Intrasexual selectionIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..Conservation biologists have altered the evolution of salmon populations in captive-breeding programs. Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?
- Which of these interactions are examples of sexual selection? Select all that apply. - Female flies prefer to mate with males that have longer eyestalks. These eyestalks provide no survival advantage, but longer eyestalks become more common over generations. -Male seals compete for territory and access to clusters of female seals. The more aggressive male seals tend to secure the largest territories and clusters. -A change in food resources on an island favors finches with medium-sized beaks. Finches with small and large beaks disappear from the island after a few generations. -Green butterflies are less likely to be eaten than yellow butterflies due to their color. Green butterflies become more numerous than yellow butterflies in the population.Two male deer compete for access to a female by sparring with their antlers. What type of selection pressure is this? a Intrasexual b IntersexualAcorn 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.
