GROWTH MODELS

 What are the assumptions for an exponential growth model?  Is this realistic?

GROWTH MODELS

LOGISTIC GROWTH PRACTICE

GROWTH MODELS  Logistic growth in the real world…

GROWTH MODELS

LIMITING FACTORS Density dependent When factors directly affect birth and death rates. Density independent When factors have little to do with population density.

LIMITING FACTORS  Density dependent prey/predator relationship

DISPERSION  Influences growth of populations  Influenced by limiting factors (especially density-dependent)

DISPERSION
