1. You have been studying a population of bluebirds. You visited the site each summer and counted the number of birds. You data are as follows:
Year: 2003, 2004, 2005, 2006
Birds: 205,240,265, 281
What was Lambda in 2004, 2005, and 2006?
2. Suppose you count a total of 315 violets in a population. r = 0.05. Five years from now, what will the population size be?
3. Now you count the columbine plant at that location and get 157. You konw that lambda is 0.98. Five years from now how many plants will there be?
4. Sketch a graph of the following populations (start all of them at N=100) Shape and direction are important. Clearly label the axes.
r = 0, r =0.10, r = -0.10, r= 0.10 and K = 500 (draw as a stable equilibrium) r = 2.0 and K = 500 (draw as unstable equilibrium)
