Pop 1 â Exponential Population Growth

Exercise #1 Begin with a continuously growing population of 9 individuals and an intrinsic rate of growth (r) of 0.33 per year. Project the growth of this population over the next 10 years.

Exercise #2 Decrease r from 0.33 to 0.27 and repeat exercise 1. Include a graph showing the two population trajectories.

Exercise #3 Assume that the population in exercise #1 has discrete as opposed to continuous population growth with Î» = 1.40. Project the growth of this population over the next 20 years.

Exercise #4 If a continuously growing population contained 47 individuals in 2000 and 156 individuals in 2013, what is r?

Exercise #5 How many years would be required for a continuously growing population of 19 individuals with r = 0.15 to increase to a size of 500 individuals?

Exercise #6 What is the doubling time of a continuously growing population with an r = 0.007?

Exercise #7 What is the probability of extinction for a species of rare bird with an initial population size of 180, b = 1.41, d = 1.39. What if there were only 30 birds to start?

Exercise #8 Observations of an endemic salamander species in the Santa Cruz mountains have declined from 21 per transect in 1975 to 14 per transect in 2014. What is Î» for this discretely growing population?

Equations

t double = ln(2)/r

P(extinction) = (d/b)^N0

Recently, the total human population reached 2372434301142 and was still growing exponentially. On a world-wide basis, the birth rate was 355 individuals per thousand people per year and the death rate was 133 individuals per thousand people per year. What was the annual rate of population growth? If you would like, you can enter your answer using scientific notation. For example, 2070000 would be entered as 2.07E06.

Please show work thank you:)
