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.
🗑
