Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.

Question

How might the following findings be understood in terms of the adaptive value of female mate preferences? Deep-voiced men have more children in a traditional hunter- gatherer culture, the Hazda of Tanzania. Taller men are more likely to be chosen in speed-dating competitions than their shorter rivals (Belot and Fancesconi 2006) and are more likely to be chosen as sperm donors by women in California (Egan 2006). Images of men with slightly bloodshot eyes are judged less attractive than photographs of the same men in which the whites of the eyes are clear (Provine et al. 2011).

why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate.
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 courtship
what are the long term vs short relationships in mate preference?
Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.
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.
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.
Male California sea lion mating success is determined by the number of mates they can acquire. Larger males are more successful at maintain larger territories. Females remain in one territory for the duration of the mating season and larger territories support more females than smaller territories. Additionally, the most successful males will fast during mating season to remain present in their territory at all times. If they leave to hunt they risk loss of their territory and access to all the females present in it. Which of the following best describes sexual selection in this species? a. Males likely engage in male-male combat to maintain territories. b. Intersexual selection is likely stronger than intrasexual selection. c. Sexual selection on the females is stronger than on the males. d. Females will mate with smaller males at a higher frequency than larger males
Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.
Consider the following argument: Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA. Which of the following pieces of evidence would be most likely to weaken this argument? Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other Data showing that food gifts are given more common among family members than between unrelated individuals in a group Data showing that individuals that share a higher percentage of DNA in a group tend to show the most altruistic behavior between themselves Data showing that the more frequent an allele of a gene occurs in a population, the more likely that population performs altruistic behaviors
What 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?
Regarding mating behavior, choose the false statement from the list: Some aspects of courtship behavior may have evolved from agonistic interactions. Courtship interactions ensure that the participating individuals are nonthreatening and of the proper species, sex, and physiological condition for mating. The mating relationship in most mammals is monogamous, to ensure the reproductive success of the pair. Polygamous relationships most often involve a single male and many females, but in some species this is reversed. Salmon swimming against the stream to lay eggs is an example of taxis. tropism. kinesis. cognitive mapping spatial learning Female Apanteles wasps lay their eggs in caterpillars of the genus Pieris. The site of the caterpillar initiates the egg laying behavior. This is an example of a fixed action pattern. problem solving behavior. habituation.…
