You monitor the white-tailed deer population for the Wright State campus and woods and estimate 14 deer in the first year and 21 deer
in the second year.
(A) Assume the deer population is growing geometrically. Based on these data, what is geometric growth rate constant (A)?
(B) Geometric growth patterns can also be modeled exponentially. If modeled exponentially, would you expect the exponential growth
rate constant () to be greater than, less than, or equal to 0? Why?
You monitor the deer population for many years. The population grows for a few more years, then seems to stabilize around 75 deer.
(C) Given this information, what would be a more appropriate model for the deer population growth? Why?
(D) What factors might be limiting the population growth? Would these factors be considered density-dependent or density-
independent factors? Why?
it is equal to zero.
