Summary Introduction
To describe:
The differential expression of alarm calls made by squirrels in the presence and absence of relatives.
Introduction:
The species live in the community and communicate with each other. The signals, which are used to warn about the predators or any danger, are called alarm calls that are mostly used in animals.

Kin Selection - Ground squirrels will often give a warning call when they see a predator, altering the other ground squirrels to the danger. Calling behavior draws attention to the calling squirrel. This being the case, why would natural selection favor this altruistic behavior? Consider this - female squirrels are 70% more likely to make a warning call than male squirrels. Also consider, male squirrels leave the colony when they reach maturity, while female squirrels stay in the colony they are born in. Explain how natural selection is working here!
Ecology regarding sexual selection:
In zebra finch females prefer males who have a larger yellow cheek patch. Researchers investigating this preference think that females must benefit from choosing males with large cheek patches. Provide three hypotheses regarding the direct, or indirect benefits, she might receive.
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

- Which of these interactions are examples of sexual selection? Select all that apply. 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. 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.arrow_forwardWhich of these interactions are examples of sexual selection?

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..arrow_forward
- Fitness and Selection: Rodent tails A researcher is studying a rodent species with a lot of variability in tail length. Individuals may have short tails, medium tails, or long tails. The researcher has noticed that a new invasive predator, which catches prey by their tails as they try to escape, seems to catch individuals with long tails more often than those with short tails. Based on a small field trial, the relative fitness of long-tailed individuals seems to be 0.6 compared to short-tailed ones (1.0), with medium tails in-between (0.8). Use the Examples tab to predict the outcome after selection for the rodent in regions with the invasive predator. What describes the population after 100 generations of selection? Choose all that apply. A-Short Tailed individuals are the most common phenotype. B-Short Tailed individuals are the only phenotype. C-This is an example of disruptive selection. D- The long tailed phenotype is no longer present E-This is an example of directional…arrow_forwardAssume 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.arrow_forwardMany lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs. A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates. Give a brief reason for your answer.arrow_forward

He collected two sets of parent offspring data, once in 1976 and again in 1978. For both years he followed birds to determine which pairs belonged to which nests. Most of the parents had been previously captured so their beak depths were known. He then captured the offspring when they fledged and measured their beak depth. He calculated the "midparent" beak depth (the average beak depth of the two parents) and then compared that to beak depth of their offspring. Here is what he found in 1976: Assume that in 1978, all the finches with beak depths less than 9.0 mm died due to prolonged drought. Use your knowledge of how quantitative traits respond to selection and the following relationship, R = h2S, to determine the following: Selection differential. Predicted response…arrow_forward
