Clutch size vs. age at first reproduction
Two hawk populations (same species, different environment) startwith one individuals each. In one population, reproductive adultsmust attain two years of age, and their average clutch size is 1.5.In the other population, adults can reproduce the first year, buttheir average clutch size is only 1. Both species are iteroparous.Assume that all adults of reproductive age reproduce every year,and survive.
How many hawks will be in each population after one year?
Two years? Three years?
Four years?
Five years?
Make a diagram to represent individuals of the twopopulations.
What conclusion can you make about the relative
importance of age of first reproduction vs. clutch size?
