Human Population Growth • J curve growth • Grows at a rate of about 80 million yearly •r =1.3% • Why doesn’t environmental resistance take effect? In the logistic population growth model, the per capita rate of increase declines as carrying capacity is reached ... population ecology describe K-selection and r-selection What sort of life tables and survivorship curves would you expect for each type? What is the population growth rate for the geese in Washington State? Population Ecology Review - Image Diversity: population growth curve Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment, such as birth and death rates, and by immigration and emigration)..
