When wolves were returned to Yellowstone National Park in 1995, some of the effects noted were increasing levels of berries available to black bears, stabilization of stream banks, increased nesting habitat for birds, and increasing beaver numbers as a result of rejuvenating aspen trees. These were later determined to be the results of reduced numbers and altered feeding behavior of elk as they were preyed upon by the wolves. Given this information, which of the following best describes wolves in Yellowstone National Park?

What contributions have laboratory and mathematical models made to our understanding of predator–prey population cycles? What are the shortcomings of these modeling approaches? What are their advantages?
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.
Dippers (Cinclus cinclus) are small birds that can be found along fast-flowing streams in Europe and Asia. They feed on insect larvae, especially those of caddis flies (Trichoptera), which they catch by sticking their heads under water and turning over stones. Describe the relationship between the abundance of caddis fly larvae and dippers?Why, is caddis fly larva abundance expressed as ‘relative abundance’? using the data in Table 2
Great white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)
Reintroducing the gray wolf as a keystone species to Yellowstone National Park has resulted in all of the following EXCEPT: Question 20 options: - More aspen trees along waterways - Better habitat for nesting songbirds - Significant losses of cattle and sheep herds in ranches near the park - Larger small mammal populations - Population regulation of herds of elk, moose and deer
Why might medium ground finch population responses to short-term episodic increases in rainfall differ from their responses to increases in rainfall lasting for years or decades?
You are part of a group of researchers examining the survivorship and fecundity of Bengal Tigers (Panthera tigris tigris) in the Kalakkad Mundanthurai Tiger Reserve in the South Indian state of Tamil Nadu. Parts of the reserve are well-protected from poaching, and other parts are largely unprotected. Over a period of several years, you’ve gathered demographic data (summarized below) on tigers in both poached and unpoached locations; assume that mx numbers represent female offspring born per female. Note that your demographic data begins at age 1, and does not include survivorship of cubs from birth to age 1. Also, note that Sx is listed here -- this is related to, but is NOT the same as lx… To calculate r, use the formula r = ln(Ro)/T.

Mongooses are not native to Hawaii. They were intentionally introduced on all of the islands in 1883 by sugarcane farmers to control rat populations on sugar plantations. They have since greatly increased their population on some islands, while no populations of mongooses are found on the islands of Lana’i and Kaua’i. Which of the following correctly identifies a challenge mongooses would face if they were introduced onto these two islands? A - There is a lack of rats and other food sources on these islands. B - These two islands have no forest reserves compared to the other islands. C - These islands contain no natural predators for mongooses so they would overpopulate. D - These two islands contain native species of birds and reptiles that would compete with the mongooses.
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.

Draw and label graphs (including zero-growth isoclines) showing the predicted behavior of the Lotka-Volterra predator/prey equations if we assume prey growth follows and exponential growth model. Show how the graphs would change of the prey follow a logistic growth model.
Only a few hundred grizzly bears remain in the contiguous United States, but populations are healthy in Canada and Alaska. Should we spend millions of dollars for grizzly recovery and management programs in Yellowstone National Park and adjacent wilderness areas?
Beige and black rabbits were introduced into two meadows. One meadow predominantly consists of volcanic soil and the other predominantly consists of clay soil. Each rabbit was marked with a dot of blue paint and the pad of his foot. The number of rabbits released and recaptured one month later are shown in the table below. Assume the number of rabbits recaptured is a direct reflection of the number of rabbits surviving. Using the data below, what conclusions can you make regarding the color of rabbits and their survival in different soil types? VOLCANIC SOIL # released #recaptures % precentage beige rabbits 137 18 13.1% black rabbits 447 123 27.5% CLAY SOIL # released # recaptures % precentage beige rabbits 393 54 13.1% black rabbits 406 19 4.7%
