Figure 1 shows the beak depths of 200 medium ground finches on Daphne Major before a severe drought began on the island. This is a normal sample of a population of medium ground finches, similar to measured samples from previous years. During wet years, all types of seeds are abundant. The medium ground finch prefers to eat small, soft seeds that are easy to crush. However, during droughts, when small seeds are not as abundant, they also eat the larger seeds on the island. a. Make two or three observations about the distribution of beak depth measurements in this sample of 200 medium ground finches. b. What is the most common beak depth of the finches living on Daphne Major in 1976? c. What is the range of beak depths in this group of medium ground finches?

https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step.   6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of these

You are evaluating multiple populations of the Karner Blue Butterfly. Below is the pairwise FST Values for the 3 populations you sampled. Given what you know about FsT and your results make a recommendation to the NYS Department of Environmental Conservation about how to manage the populations. Population 1 Population 2 Population 3 Population 1 Population 2 Population 3 0.05 0.67 0.46 (Hint: The measurement of gene flow (FSt) between population 1 and population 2 is 0.05) O a. The results suggest that each population is quite different from the other, such that each population should be managed as a distinct and unique population. O b. Populations 1 and 2 are completely isolated from each other and should be managed separately even though they are both more similar to population 3. O c. There is evidence of gene flow between populations 1 and 2, and they should be managed as a single population while population 3 is unique. O d. There is no evidence of differentiation between all…

In this question, why B is correct and C is wrong?   Bighorn sheep are an iconic species in the western United States, however, their population size is drastically lower than it once was historically. These sheep inhabit montane patches surrounded by urban and agricultural landscapes. Accordingly, bighorn sheep can be considered a metapopulation. Wildlife managers would like to increase the patch occupancy of bighorn sheep. Which of the following would be the most effective conservation/restoration strategy?     None of these statements is an effective conservation strategy.   Increase patch size and quality, and decrease the distance between patches.   Increase patch size and the distance between patches, and decrease patch quality.   Increase the distance between patches and patchy quality, and decrease patch size.   Decrease patch size, distance between patches, and patch quality.

You wish to determine the abundance of the state- and federally-endangered Prairie Fringed Orchid (Platanthera lecuophaea) in a local prairie. (a) The prairie is approximately 100 acres of relatively flat terrain. Considering the “basic” sampling strategies, what might be a good sampling design (can just give the name)? Why? (b) You decide also to evaluate the abundance of the orchid in another prairie. The second prairie is of similar size but has a hilly terrain. What might be a good sampling strategy? Why?

A population of beetles exhibits two phenotypes: red and blue. The genotypes RR and Rr result in red coloration and the genotype rr results in blue coloration. The alleles are equally prevalent (i.e. both frequencies are 0.5). A new predator is introduced and preferentially feeds on blue beetles. What do you expect to happen to the allele frequencies over time? The frequency of the rallele is expected to increase because of predation pressure. O The frequency of the Rallele is expected to increase because of predation pressure. There is not enough information to predict what will occur. O There will be no change because of the Hardy-Weinberg equilbrium.

A southern European songbird, the blue tit, breeds in two habitats that differ greatly in quality.In deciduous oak forests, blue tits produce so many young that their populations have thepotential of growing at the astronomical rate of 10% annually. In evergreen oak habitats, blue titsperform poorly, with populations showing a potential for a rapid decline of 13% annually. Yetblue tits persist in both habitats. Why?

Oaks in California are suffering from a phenomenon called sudden oak death (SOD).  This has the potential to convert oak-dominated communities to communities made up of mostly grasses and smaller plants.  How would this change the abundances of the tick species described in the article?  Make a prediction for each of the three most abundant species, and describe the specific results in this article that justify your prediction.   Article Reference: Abiotic and habitat drivers of tick vector abundance, diversity, phenology and human encounter risk in southern California By: Andrew J MacDonald
