Term | Definition |
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, |
