- 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.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. AnswerOnce an abundant species in Alberta, the caribou population is currently staggering at approximately 6,700 individuals. Little Smoky caribou herd is located in Northern Alberta, and its population is a risk of extirpation. In 1970, there were only 123 caribous in the Little Smoky area with a per capita growth rate of –0.258 between 1970 and 2012. What was the population of Little Smoky caribou herd in 2012? Express your answer rounded to the nearest whole number.
- 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.S2) Below are two tables showing the population size and deaths by age for one year in the states of Louisiana (LA) and Florida (FL).
