Population |
A group of the same type of organisms that live in the same place at the same time. |
|
Population Density |
How densely populated organisms are in a certain area. |
|
Population Model |
Type of mathematical model used to study population dynamics. |
|
Carrying Capacity |
The number of living organisms an environment can support without environmental degradation. |
|
Logistic Model |
A statistical model that shows risk as a function of exposure to a risk factor. |
|
r-strategist |
A type of organism in which their reproductive strategy is to go for quantity over quality; they try and make as much offspring as possible and not a lot of time put into them. These organisms tend to mature fast and live short lives. |
|
Population Size |
The amount of population in an area. |
|
Dispersion |
How organisms gather in an ecosystem; whether it is a uniform fashion or random. |
|
Exponential Growth Curve |
A type of growth in which the rate is proportional to the increasing number in size in an exponential growth function. |
|
Density Dependent Factor |
Factors where the effects on the size or growth of a population vary with the density of the population itself. |
|
Density Independent Factor |
Any factor limiting the size of a population whose effect is not independent on the number of individuals in the population. |
|
k-strategist |
A type of organism that goes for quality over quantity in reproduction; they focus on raising their offspring to prosper, and don't have many offspring. These organisms tend to live longer as well, and take longer to mature. |
