|
Age Structure |
The proportions of individuals at various ages that can have a strong effect on how rapidly its size increases or decreases |
|
|
Survivorship Curve |
a way to represent the age structure of a population showing the percentages of the members of a population surviving at different ages |
|
|
R-Selected Species |
Species with a capacity for a high rate of population increase |
|
|
K-Selected Species |
Species that do well in competitive conditions when their population size is near the carrying capacity |
|
|
Opportunist |
species that reproduce and disperse rapidly with conditions are favorable or when a disturbance opens up a new habitat or niche for invasion |
|
|
Competitor |
able to fight for resources when the population is close to carrying capacity |
|
|
Logistic Growth |
involving rapid exponential population growth followed by a steady decrease in population growth with time until the population size levels off |
|
|
Exponential Growth |
when a population starts slowly then accelerates as the population increases because the base size of the population is increasing |
|
|
Density - Dependent Factors |
factors that limit population growth have a greater effect as a population's density |
|
|
Density - Independent Factors |
Factors that are not dependent on the density of the population |
|
|
Intrinsic Rate of Increase |
the rate at which a population would grow if it had unlimited resources |
|
|
Carrying Capacity |
The maximum population of a given species that a particular habitat can sustain indefinitely without degrading the habitat |
|
|
Environmental Resistance |
Consisting of all factors that act to limit the growth of a population |
