We often, however, dont make the connection that the amount of available resources dictates the size of a population that a population will grow when resources are in surplus, decline when resources are scarce, and stabilize when the population is at the maximum level that can be sustained. Species that have higher population densities than the core species enter and leave flocks as flocks pass through their territories, whereas species with lower population densities than the core species alternate between several flocks on a daily or hourly basis. Climbing palms or rattans (Calamus) are prominent lianas in Asian rainforests, where the stems, which are used to make cane furniture, provide a valuable economic resource. The growth rate of a given population is the intrinsic rate of increase of that population. Lowever to do so, you'll need to predict the intrinsic rate of increase and carrying capacity.
