Longest-running studies of its kind the study of moose and wolves, The island provides conditions for a unique natural experiment to study this predator- prey system. Isle Royale is large enough to support a wolf population, but small enough to allow scientists to keep track of almost every single wolf and moose on the island, making it a practical place to study population ecology Population ecology population ecology is the study of changes in the size and composition of populations and the factors that cause those changes 00:02 01:28 Population ecologists are interested in how and why ecological populations grow and shrink in the ways that they do. The basic ideas in population ecology are not complicated, but they do involve a little math Population dynamics population dynamics refers to how population interact and change over time Succession ecological ____ is the relatively predictable change in community composition through time, generally following a disturbance. Environmental and biological conditions determine which species appear during different successional stages Exponentially ... Per capita means per individual. A per capita growth rate, for instance, is the number of individuals in the next unit of time per individual that exists now Carrying capacity a population's carrying capacity (symbolized by k) is the maxium stable population size of the species that the local environment can support Stable population size ... Logistic growth ... Logistic growth model ... Population cycling ... 00:03 01:28 Population cycle when a population cycles, its size periodically increases and decreses following a regular or predictable pattern Paradox of enrichment is a phenomenon in population ecology that occurs when food availability for a prey species increases dramatically, and results in the destabilization of the predator population or the entire food chain.
