BIOA02H3 Chapter 54: Chapter 54 Population Ecology

Nairobi has a birth rate of 3.3 individuals per individual per year and a death rate of 3.2 individuals per individual per year.

a. What is r?

b. Is the population declining, growing, or remaining constant based on your answer for part a.

c. Assuming exponential growth, how many years are necessary for the population to double?

d. If the population is presently 49. What will be the population in 25 years?

e. If the carrying capacity were 105, what would the population be in 25 years?

A population of a species exhibits logistic growth. If thecarrying capacity of their habitat is 240 individuals and r = 0.3(individuals per month), what is the maximum population growth ratefor the population? Show all your work.

An ecologist monitors the population dynamics of Tazmaniandevils. Sampling individuals in the population reveals aheterozygote frequency of 0.2. After a forest fire, surviors beginto repopulate and have population sizes of 6, 17 and 62 in the nextthree generations. Calculate, Ne, the heterozygote frequency afterthree generations and the inbreeding coefficient for thispopulation after three generations.
