During 24 months, a population of 5,000 prairie dogs experienced 6 500 births and 5 560 deaths. Forty two prairie dogs left the population, and 85 prairie dogs joined the population. Calculate the growth of the prairie dog population during the 24 months. Calculate the per capita growth rate of the prairie dog population and the per capita growth rate per year. Show all work and explanation.

If each adult female powerful owl produces 1 female juvenile (F) each year, the adult survival rate (Sa) is 0.8, the juvenile survival rate (Sj) is 0.4, and the population is N2022=1400 adult females and 1400 juvenile females in 2022, what will be the female population size in 2027 (N2027)? Show your calculations. (hint: use excel to set up a model and check your work)

A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.

What is true of a population with a logistic growth pattern? Choose All That Apply It has growing at a constant rate It is at or close to its carrying capacity Its K-N/K value does not change It has an exponential growth phase

A population of grey squirrels started with one pair and grows logistically with annual r = 1 and K = 42. Use the logistic growth equation to predict the population size 14 years after the first pair arrived.

Examine the characteristics of logistic growth by completing each statement. Not all choices will be used. *1 S exponential four competition follicular lag two J stable equilibrium Logistic growth results in a(n) curve when graphed. This growth curve exhibits time. The phase exhibits a slow growth rate due to the small number of individuals within the population early on. Exponential growth slows as increases during the deceleration phase. As the population size grows, the growth rate will accelerate due to biotic potential during what is called the growth phase. -shaped growth distinct phases over Finally, the carrying capacity is reached during the < Prey n for resources phase where birth and death rates are equal

PRACTICE Calculate the population densities for the following countries. Round to two decimal places. Country: Albania Albanla- Population: 3 002 859 Area: 28 748 km2 Country: Colombia Population: 45 239 079 Colombla Area: 1 138 910 km2

The following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…

Use the cohort life table below to answer this question. You can assume the population started with 200 individuals and thát there is a 50/50 male-to-female ratio. Age Class Survivorship Fecundity 0-1 1.0 1-2 0.9 2-3 0.4 3-4 0.0 0. The population described in this table is: O A) growing O B) declining O C) stable
