Carrying Capacity | The maximum number of individuals of a species which the ecosystem can support: mediated by limiting factors |
Density Dependent Limiting Factors | Factor which increases/decreases dependent on its population numbers
[Crowding, competition] |
Density Independent Limiting Factors | Factor not dependent on population size [usually abiotic]
[Temperature, Rainfall] |
Population Growth Factors | Immigration/Emigration
Fercundity
Mortality |
Lincoln Index | Capture-Recapture method [Capture, mark, release, recapture]
N=(n₁×n₂)/n₃
N = Total Population
n₁ = Number collected in the first capture
n₂ = Number collected in the second capture
n₃ = Number marked in the second capture |
J-Curve | Exponential: Ideal conditions, unlimited resources |
S-Curve | Logistic: More Realistic, exponential until carrying capacity reached due to limiting factors |
