One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches? Far fewer black beetles would I + Which of the five conditions of Hardy-Weinberg equilibrium would be violated in this situation? V [ Select ] Genes are now mutating. Mating is no longer random. The population size is now much larger. The population would experience natural selection pressures. There is now immigration of individuals into the population.
Most Swiss starlings produce four to five eggs in each clutch. Starlings producing more than this have reduced fitness. Which of the following statements best explains this situation? O The starling parents do not care for their young, reducing their fitness. O The ecosystem can only support two offspring, reducing the fitness of both populations. O The population of starlings have limited resources to care for their young. O The starlings have fewer habitat options and fewer offspring, reducing their fitness.
Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consistingof 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there isno migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygoteshave shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggyindividuals, and 84 rough individuals.a)What is the size of the population?b)Do the alleles have a simple dominance relationship? Describe.c)What are the frequencies of the two alleles?d)Is the population in Hardy-Weinberg equilibrium?If not, how do you know, and what might be the cause?

Suppose you watch the buffalo and discover that while all the females breed, a small number of males(10) establish breeding harems, while the other males do not breed.a) What is the effective population size of this herd? That is, what size "ideal" population ofbalanced sex ratio would have genetics similar to this population?b)How does the effective population size compare to the actual population size?c) Under Hardy-Weinberg equilibrium, what…
A breeding pair of birds receives help raising their young from an unrelated male bird. This behavior is termed cooperative breeding and in some ways this seems like an evolutionary paradox since helpers seem to be acting in ways that increase the fitness of others at their own cost. .How might providing this assistance improve the fitness of the unrelated male bird? Increasing the fitness of the unrelated offspring directly increases the unrelated bird's fitness O The cooperative relationship helps the unrelated male survive until he can find a mate and produce offspring of his own Rearing unrelated offspring delays sexual maturity in the helper bird so he has fewer offspring over the course of his life. Because he does not ever produce offspring of his own, the helper bird has a longer and healthier life.
You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators Design an experiment to test the hypothesis that this turtle…

Humans often kill rattlesnakes that they encounter. Rattlesnake populations close to human habitation thus experience higher adult mortality rates. As Dr. Beck has found in his research on Northern Pacific Rattlesnakes in Washington state, these populations tend to evolve a shift toward more "r-selected" life-history strategies, such as (select all that apply): Smaller size at first reproduction. Early age at first reproduction. O More extensive parental care. O A few large offspring per reproductive event. Lots of small offspring per reproductive event.
The way an individual's energy is divided among growth, maintenance, and reproduction is controlled by the species' genes and is shaped by natural selection. Different species divide their energy in different ways, but the way energy is divided results in the greatest given the species' niche.
