- The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 5330 births, 4809 deaths, 12 immigrations and 45 emigrations. Calculate the per capita growth rate. Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign.In 1975, the population of Peary caribou among the Arctic islands was around 28 000. In 1976, there were 1600 deaths and 900 births, and no immigration or emigration. Calculate the population change as a percentage. Show your work.In 2017, 16 bison were released into Elk Island National Park. Within the next five years, 49 more bison will be released into the 1,200 km2 area. During the study period, it is expected that 45 calves will be born and 13 bison will die or be removed from the study area. What is the expected per capita growth rate of the bison population during this study period? Express your answer rounded to two decimal places. If the population is decreasing indicate this with a negative sign.
- The island of Isle Royale in Lake Superior has historically contained both moose and wolves. In recent years, the number of wolves has dwindled, leaving few predators for the moose. This has led to a large increase in the moose population on the island. The following information is from 2018. Using this information and the equation shown, the growth rate for the moose population on Isle Royale can be calculated. Based on the current population and the growth rate, what type of growth model would be expected? K = 2,000 moose N = 1,500 moose Rmax = 0.5 where: dt = change in time N=population size ax =maximum per capita growth rate of population K= carrying capacity A logistical growth model would best represent this population because the moose population will decrease over time. An exponential growth model would best represent this population because there are few predators for the moose on this island. A logistical growth model would best represent this population because the increase…The island of Isle Royale in Lake Superior has historically contained both moose and wolves.

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/km2
- 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/km2The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image If the death rate decreased, what would happen to the population trajectory for population A? a) increase faster b) increase slower c) decrease faster d) decrease slowerFlowering rush (Butomus umbellatus) is a pink flowering perennial that has been identified as a prohibited noxious weed in Alberta. It is native to Europe, Africa, and Asia, but due to its prolific growth rate on shorelines, it has been crowding out the native species of Alberta.
