In the article “ Environmental and Social Determinants of Anuran Lekking Behavior: Intraspecific Variation in Populations at Thermal Extremes"
What 4 populations were being studied and compared?
Step by step
Solved in 2 steps
- In the article “ Environmental and Social Determinants of Anuran Lekking Behavior: Intraspecific Variation in Populations at Thermal Extremes" Question: What 4 populations were being studied and compared?How does group selection theory explain the altruistic behavior of animals and why is this explanation problematic for advocates of inclusive fitness theory?Out of the three patterns, disruptive, directional, and stabilizing, which pattern of natrual selection is currently exhibited by banded snails as a result of human interference due to the urban heat island?
- Does Figure 6.5(C) use relative fitness or absolute fitness of the horned lizards in calculating the fitness function? How can you tell from the graph?Bigger dogs will have more puppies than smaller dogs in a litter. What is the independent variable, dependent variable, constant, and control group?What is the selective advantage to winners, as well as to losers, that aggressive encounters within species for social dominance are usu-ally ritualized displays or symbolic fights rather than unrestrained fights to death?
- Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.Which is the Dependent Variable and the independent variable in the below question. The beak length and depth for medium ground finches recorded over 5 years?What are indirect fitness benefits of siblicide? When would an individual gain more from siblicide than from inclusive fitness benefits? When might it be worth it for a subordinate to fight to the death with its dominant sibling?
- How does reciprocal altruism contrast with kin selection as an expla-nation of apparently altruistic behavior? What evidence from vam-pire bats supports reciprocal altruism?Earlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?Endler (1980) set up two experiments, one in the greenhouse and one in the field to test the influences of mate choice and predation in determining colorfulness of male guppies. Identify the roles of mate choice and predation in determining colorfulness of male guppies. Identify the advantage and shortcomings of the greenhouse experiments. Identify the advantages and shortcomings of field experiments along the Aripo River. Identify other factors, especially physical and chemical factors, might influence male color.
