The intrinsic rate of increase (r) for northern elephant seals about 0.15 (per annum). We will assume that population regulation is linearly density dependent.
a. If the carrying capacity of elephant seals at a recently recolonized island is 1000 adult females and the initial population size is 100, how many more years (approximately) will it take for the population to grow to K?
b. If the island population overshot carrying capacity to 1900 adult females, how many more years (approximately) will it take for the population to decline to K?
- i know were suppose to use the forumla N(t)= K/1+[(K-N(o)/N(o))]e^-rt, it said how many years it take to grow to K and i set N(t) to 1000 and plugged everything in to solve for T but when i do the math i know the answers wrong
