Summary Introduction
To predict: Which type of male would have a higher mating success if an initial population of side-blotched lizard has higher numbers of orange-throated males and how the male population would change further.
Introduction: The game theory states that animals explore certain strategies in situations where the outcome depends on the individual’s strategy and the strategies of others involved. The mating behavior of side-blotched lizards (Uta stansburiana) is an example of game theory in animal behavior.

Question
10 male parrots wish to mate with a female. The female chooses to mate with the male that has the brightest tail feathers.
Male giraffes perform mating dances. The ones that perform the dance better are chosen by the female as a mate.
Male kangaroos fight each other, the winner claims the female to mate with.
Male red-winged blackbird sing and display their feathers to establish their territories. All of the females in that territory will exclusively mate with that male.
The impressive feathers of a male peacock are the result of this type of sexual selection

A.
Intrasexual selection
B.
Intersexual selection
Fireflies use light signals to locate mates. Individuals with smaller, and thus less visible, lightorgans are less successful at mating. In January of 1985, a highway with bright streetlightswas constructed through a prairie where a firefly population lives. This created a selectionpressure for brighter (larger) light organs in the population. The light organ was, on average,4 mm long in the population prior to the construction of the highway. In 2005, the averagelight organ size in this population (before mating) was 6 mm. This firefly species has1 generation per year, and the narrow sense heritability ( h^2) of the light organ is 0.1.a) What is the strength of selection (S) for the larger light organ.b) What was the mean light organ length of successfully reproducing individuals in 1985(the first year of selection)?

- Zooplankton (small animals that live suspended in the water) are sometimes isolated in small ponds caused by glaciers, called prairie potholes. Movement of zooplankton between these habitats is very limited. Because of the small size of zooplankton, each pothole can maintain a very large population. There are no known traits that females use to determine male quality, when males are present, nor is there any obvious sign of male-male competition. When assaying the populations for genetic diversity, you find that all have the same alleles and no new alleles have appeared since these habitats were colonized. At this time, no known traits are under selection. If all of these things are true, then are these populations likely to exhibit changes in allele frequency in the immediate future? O Yes, they will exhibit shifts in allele frequency in the next generation or two in random directions No, if these conditions continue the allelic frequencies will not change Yes, they will exhibit…arrow_forwardYou are studying the mating patterns of a group of elephant seals.

- 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.arrow_forwardWhich of the following is an example of a question about mechanism (not function)?

- The second assumption in formulating Lack's (1947) hypothesis is that clutch size affects only offspring survival. The data that are presented in the figure were obtained in an experiment conducted by Schluter and Gustafsson in 1993 to test this assumption. The researchers removed or added eggs to nests and monitored the offspring that hatched from the nests, recording subsequently the reproductive output for offspring females after they had matured. i. Females reared in nests from which eggs had been removed produced larger clutches. ii. Females reared in nests into which eggs had been added produced smaller clutches. iii. Observations described in statements i and ii are consistent with the second assumption. iv. Observations described in statements i and ii reveal a trade-off between offspring quantity and quality. Question 3 options: A) All statements convey accurate information. B) Statements i and ii convey…arrow_forwardSome bird species mate monogamously for life (i.e., individuals keep the same partner year after year). Other bird species are seasonally monogamous: they choose a new mate every year. Some bird species have what is called helpers-at-the-nest; these helpers are older offspring who stick around and assist their parents in taking care of babies born the next year. Kin selection would predict that you would find more instances of helpers-at-the-nest in the species that mate monogamously for life than in the seasonally monogamous species. Why? Be sure to address why they might still help in seasonally monogamous pairs.arrow_forwardIn 1983 a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. Females have less white in their tails than do males, and display it less often. (Pamela J. Yeh. 2004. Rapid evolution of a sexually selected trait following population establishment in a novel habitat. Evolution 58[1]:166-74.) Refer to the paragraph on dark-eyed junco birds. The UCSD campus male junco population tails are about 36% white, whereas the tails of males from nearby mountain populations are about 40-45% white. The founding stock of UCSD birds was likely…arrow_forward
