Document Summary

Lec 30~ population ecology 3 population regulation real world applications. Assumption: ideal conditions (obviously this is unrealistic!: unlimited food and water, unlimited space, no predators, no parasites, pathogens, no immigration or emigration, all deaths occur due to old age. But if we make these assumptions we can calculate the population"s. Therefore the exponential growth model is: rmax=intrinsic rate of increase. Reproductive rate of a pop under ideal conditions listed above: rate of reproduction biologically determined by the species with no other environmental factors involved rmax=related to generation time of a organism. Resources in the environment may, however, be renewed, or made available. The maximum number of individuals of any species that an environment can support indefinitely (meaning resources are renewed at a constant rate) is called the carrying capacity, or k. K is defined for each population, not each species. This is because k is a property defined by the resources in the environment in which the population lives.
