Unformatted text preview: JP Seral November 26, 2007 APES 5 th Chapter 9 Terms: Population Dynamics: Changes that occur in a population in response to environmental stress or changes in environmental conditions. Biotic Potential: Factors allow a population to increase under ideal conditions, potentially leading to exponential growth. Environmental Resistance: Affects the young more than the elderly in a population, thereby affecting recruitment (survival to reproductive age). Carrying Capacity: Maximum number of individuals a habitat can support over a given period of time due to environmental resistance r-selected species: Are opportunist species, spend most of their time in exponential growth, maximize reproductive life, minimum life, and can gain a foothold in changed environmental conditions. K-selected species: Competitor species, maintain population at carrying capacity (K), maximize lifespan, thrive best in ecosystems with fairly constant environmental conditions....
