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,

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
