In some cases, a population can exceed its carrying capacity for a brief period of time. In a population of dragonflies that approaches its carrying capacity, many females use the last of their energy reserves to reproduce. As a result, the population size reaches 675 dragonflies, but the estimated carrying capacity () of the area is 550 dragonflies. The rmax value for this population is 0.5. Calculate the rate of population growth (dN/dt) & the per capita rate of growth, r(1 – N/k).

A population of spotted hyenas in a South African National Park currently has 87 individuals. The carrying capacity for spotted hyenas in the park is estimated to be 125 hyenas & the intrinsic growth rate () is 0.25 hyenas/year/hyena. What is the instantaneous rate of population growth of the spotted hyena population?
