An ecologist is studying a population of beetles and determines N=2000. During same time (that the population is N=2000), he also records 200 births and 120 deaths in the population over a one month period. Using this information, answer these questions.

a) Estimate r, the per capita growth rate in months and use it in the continuous model of population growth to estimate population size in 8 months.

b) Given the same per capita growth rate as above, how much time will it take the population to double?

c) Assume K for this population is 8000 (and N=2000), is the population growth rate increasing or decreasing?

d) Given that K = 8000, what is the population growth rate when N=2000?

e) What is r in time units of years?

Solutions

Expert Solution

Answer-

a) per capita growth rate, r = 0.04/month

A population of splendid fungus beetles lives in my backyard. A gene determines how many spots they have on their hindwings. Those with the dominate phenotype (BB and Bb) have 3 large spots, and those with the recessive phenotype (bb) have 7 small spots. The population isn't very big - only 50 beetles. I counted them and notice that 18 have three large spots and 32 have seven small spots. If there is no natural selection, mutation or gene flow...
