- It is estimated that approximately 20,000 grizzly bears live in Western Canada, Yukon, and Northwest Territories. Currently, there are 146 grizzly bears remaining in Jasper National Park in an area of 7500 km2. Calculate the density of the grizzly bear population in Jasper Park. Express your answer as a value rounded to two decimal places. Units = grizzly bears/km2It is estimated that approximately 20,000 grizzly bears live in Western Canada, Yukon, and Northwest Territories. Currently, there are 198 grizzly bears remaining in Jasper National Park in an area of 9500 km2. Calculate the density of the grizzly bear population in Jasper Park. Express your answer as a value rounded to two decimal places. Answer grizzly bears/km2The Arizona Forest occupies 87,174,334,009 sq. miles land that cater different kinds of species. One of which were the leopards. As of 2019, the total population of leopards is 26,753. Due to severe changes of the environment, there is an average of 571 leopard’s dies while only 255 were given birth each year. In 1950, their population is 63% higher from the current population.

- A few plant-eating salamanders manage to float on a log to a large island in the Pacific that did not have any other salamander species previously. The salamanders find the island has abundant plants for food and no predators. On average, a salamander has four offspring per year and lives for one year. Refer to the equation for the logistic growth model if you were modeling salamnder population growth with this logistic growth equation, during the first few years, a) N<K b) N=K c) N>K d) there is no relationship between N and KIf the population of 150 squirrels at UofL has 15 births this year, what is the per capita birth rate? - 0.1 squirrels/yr/squirrel If the population of 150 squirrels at UofL has 10 deaths this year, what is per capita death rate? - 0.067 squirrels/yr/squirrel Calculate the intrinsic rate of increase for this squirrel population, using your answers to the questions above. - 0.03 squirrels/yr/squirrel Between having plenty of shelter in the trees and scavenging through the campus garbage, UofL squirrels have seemingly unlimited resources. Using the information you've calculated so far, determine the growth increment for the coming year for the UofL squirrel population. - 4.5 squirrels/yr Let's say that, after you calculated your predictions for unlimited growth of the UofL squirrel populations in the questions above, a bad storm comes through campus and wipes out half the trees!
