- Explain alarm calling in prairie dogs and ground squirrels. what are some data that indicatewhether alarm calling is selfish or altruistic behavior.? why altruistic behavior represents and evolutionary paradox. What is the primary hypothesis for themechanism that led to the evolution of alarm calling?In 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..Male and female ruffed grouse look similar, except during courtship when the males raise their neck feathers and fan out their tails to create a visual display (Figure 2). These grouse spend much of their time on the ground. How might natural selection have favoured this particular adaptation? A Figure 2 Male ruffed grouse in courtship display
- Briefly describe how observing beak sizes in finches before and after a drought in the Galapagos provides evidence for evolution. Meant to be a short answer like 4 sentences or so is greatYou want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page. CHARACTER SEXUAL DIMORPHISM MALES FEED YOUNG Cassin's Vireo No No Red Fox Sparrow Cape May Warbler Cedar Waxwing Golden-Crowned Kinglet Pyrrhuloxia Yes No No No No Yes No Yes Yes No California Gull No Yes Note: This data is fictional 5) Which of the hypotheses in part 4 is consistent with your analysis?

- Hamilton's Rule describes the relationship between cost and relationship in the evolution of altruistic behavior. Which of the following do not support Hamilton's rule: In colonies of Naked Mole Rates, only one female is reproductive. Cattle egrets sometimes kill their siblings. Wood mouse sperm will sacrifice themselves to assist a "sibling" sperm to fertilize an egg. O A Prairie Dog trills in response to an oncoming predator and is more likely to be eaten because it exhibits this behavior.Discuss male-male violence and the evolution of human warfare in respects to early evolutionary beginnings with primate behavior. References are the books "Primate Behavioral Ecology" by Karen Strier and "Planet Without Apes" by Craig StanfordFemale 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?
