Document Summary
Why is it important: models assume populations have a carrying capacity. Optimal group size model (same graph as optimal territory) Optimal foraging model: conservation planning, harvest levels. Primates in west + central africa harvest primates for local consumption or for sale. Local people need some sort of protein (can"t stop harvest completely) Makes it difficult to set conservation levels. Don"t know what the habitat can actually support: humans probably haventt reached k yet. Density dependent: the control on that population is dependent on the density of that population: self-adjusting effect, bigger population = more contact = spread of disease = increased death = decreased population. Density independent: population change is independent of its size: weather, natural disaster, large freeze will kill off butterflies that are still active no matter the size of the population. If you look at different populations and you correlate it to the abundance of legumes, there is a nice correlation.
