Definitions

TermDefinition
Overshoot When a population grows beyond its carrying capacity.
Die-off A substantial decline in density that typically goes well below the carrying capacity.
Population cycles Regular oscillation of a population over a longer period of time.
Delayed density dependence When density dependence occurs based on a population density at some time in the past.
Damped oscillations A pattern of population growth in which the population initially oscillates but the magnitude of the oscillations declines over time.
Stable limit cycle A pattern of population growth in which the population continues to exhibit large oscillations over time.
Deterministic model A model that is designed to predict a result without accounting for random variation in population growth rate.
Stochastic model A model that incorporates random variation in population growth rate.
Demographic stochasticity Variation in birth rates and death rates due to random differences among individuals.
Environmental stochasticity Variation in birth rates and death rates due to random changes in the environmental conditions.
Habitat fragmentation The process of breaking up large habitats into a number of smaller habitats.
Rescue effect When dispersers supplement a declining subpopulation and thereby prevent the subpopulation from going extinct,
