- The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 5054 births, 4567 deaths, 25 immigrations and 52 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.ASAPDeer Population on an Island 120 100 96 80 78 60 6아 40 36 20 TO 1 2 3 4 5 6 7 8 9 10 11 12 Number of Months Dear population 1-During which months was the growth of the deer population exponential? | 2-Give one possible reason why the population decreased after 5 months 3-What is the approximate carrying capacity of the island? 4-Explain "carrying capacity" 5-What type of density independent factors may cause the population to decrease (name 2)? 6-What type of density dependent factors may cause the population to decrease (name 2)? 7-Overall, do deer populations seem to exhibit exponential or logistic growth?

- The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 4557 births, 3587 deaths, 84 immigrations and 48 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. AnswerIn 2017, 16 bison were released into Elk Island National Park. Within the next five years, 42 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.In a forest in India, there are 800 axis deer and 500 barking deer. The forest can support a maximum of 1,200 barking deer. The competition coefficient of barking deer on the axis deer is 0.25, and the competition coefficient of the reverse pair is 0.5. The intrinsic growth rate of barking deer is 2.0. Based on the Lotka-Volterra model, the population growth rate for barking deer is 416.67 Now, let's see if the two species can coexist in this forest. You are provided with some additional information: the carrying capacity of axis deer is 4,000. Determine if the two species can coexist.

In 1976, there were 1600 deaths and 900 births, and no immigration or emigration. Calculate the population change as a percentage. Show your work.Based on the equation for logistic population growth, Logistic Growth O A. new Individuals are added most rapidly at low population sizes. This figure displays the equation for logistic population growth and visualizes population growth as a function of time (number of generations) as it approaches carrying capacity. N stands for population size, K stands for carying capacity, and r stands for intrinsic rate of increase. O B. population growth never exceeds K. C. growth rate decreases as N approaches K.

Describe the relationship between population size and growth rate. üüFlowering 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. The following table shows the population growth of flowering rush in Chestermere Lake of Calgary.
