In the Rocky Mountains, valley bottoms provide a high quality wildlife habitat and offer a way for wildlife to move through the mountain environment. However, valleys are also important to humans, as most human activity in the Rockies is confined to the valley bottoms. This results in competition for space between wildlife and humans, which poses a significant problem for both. A wildlife corridor is an area of habitat that connects wildlife populations that are separated by human activities or structures such as roads or development. How do wildlife corridors increase gene flow and maintain diversity in populations?

A large protected area is set aside to aid in the maintenance of an endangered cheetah population. The population of cheetahs in this area increases by 30 percent over the next ten years. Then, a highway is built through the middle of the protected area. In the following ten years, the cheetah population declines by 20 percent. This suggests that the highway acted as a corridor, allowing cheetahs to move out of the area. cheetahs fare best in a very large protected area. cheetahs are undergoing a natural population cycle.
In many cases, circumstances prevent preservation of a large, unbroken area of a threatened species’ habitat. Sometimes, however, several smaller areas can be protected. In such cases, conservation biologists stress that the small areas must be linked by corridors of the appropriate habitat. Can you explain why?

In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…

NOTE: The image you need to see in order to answer this question is attachedA developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. D) Site C has more unique species in it than either Site A or Site B
PoN Background Information: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus, the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and als increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The results of this program are shown in the following graph (below).

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. O Increase patch size and quality, and decrease the distance between patches. O Increase patch size and the distance between patches, and decrease patch quality. O Increase the distance between patches and patchy quality, and decrease patch size. Decrease patch size, distance between patches, and patch quality.
Wildlife Refuges in the United States: Group of answer choices have their largest total land area in Florida. are much less effective for preserving species than zoos or botanic gardens place a ban on oil and gas exploration in their boundaries. preserve habitat and are thus one of the best approaches to conserving wildlife
When a large, contiguous area of habitat is reduced in area and divided into smaller, more scattered patches, the process is called habitat elimination habitat exploitation resource partitioning habitat fragmentation resource loss
Exotic or non-indigenous species are species that have been transported to new locations by humans, either intentionally (e.g., the ornamental trade, fisheries or aquaculture) or unintentionally (e.g., accidental release of aquarium or pet species), and have established one or more populations in their new location. Exotic species may become invasive species if they expand their range in their novel region and become abundant. The presence of invasive species is of concern because invasive species can have negative effects on the affected ecosystems or commercial interest. Research an invasive species and include the following: Scientific name and common name (if the species has one) The species native region and invaded region Consequences or concerns that the species presents.
