Population Ecology

Population A group of individuals of a single species in a given area Density Dispersion

Demography The study of statistics that affect population size

Life Table

Reproductive Table

Population Growth Exponential Growth dN/dt = r max N dN = change in number dt = change in time r max = intrinsic growth rate N = number of ind.

Population Growth Logistic Growth dN/dt = r max N (K-N) K dN = change in number dt = change in time r max = intrinsic growth rate N = number of ind. K = Carrying Capacity

Logistic Growth

Life Histories r selected Large number of offspring No parental care Small in size Short lifespan K selected Small number of offspring Large amounts of parental care Large in size Longer lifespan

Human Population and ZPG Which type of growth do humans follow? What is ZPG?
