r and K selection

Paul Andersen explains the differences between an r and a K selected species.  He starts with a brief description of population growth noting the importance of; r or growth rate, N or number of individuals in the population, and K the carrying capacity.  He describes three different survivorship curves found in organisms.  He lists the characteristics of r-selected species like bacteria and K-selected species like humans.
