Large islands tend to be more species rich than small islands
|
Area effect
|
|
Islands near to the mainland tend to be more species rich than distant islands
|
Distance Effect
|
|
The mainland (in island biogeography theory)
|
Source Pool
|
|
The rate at which new species colonize an island
|
Immigration Rate
|
|
The rate at which species disappear from an island
|
Extinction Rate
|
|
The rate at which species (on an island currently in equilibrium) replace each other
|
Turnover rate
|
|
ecological succesion that comes from after a disturbance that creates new substrate. (Volcano, Glacier).
|
Primary Succession
|
|
Ecological succesion that comes after a disturbance that removes significant amount of biomass, but leaves the existing substrate.(forest fire, abandoned tilled cropland).
|
Secondary succesions
|
|
The first of the species to colonize a recently disturbed habitat
|
pioneer species
|
|
the late successional community that exists at or near equilibrium

Rank abundance graph
|
|
The number of species in a sample

The uniformity of species relative abundance
|
Species Evenness
|
|
The number of species that are represented by only one individual in a sample
|
Singletons
|
|
The number of species that are represented by exactly two individuals in a sample
|
Doubletons
|
|
Plotting the expected species richness against the number of individuals sampled
|
Rarefaction curve
|
|
The number of species per area or per volume
|
Species density
|
|
The act of searching for and obtaining food resources
|
Foraging
|
|
The physical space that is occupied by an organism
|
habitat
|
|
Amount of food (or energy) consummed per unit time
|
Intake rate
|
|
In theory, an individual that is able to select habitat best suited for survival and reproduction
|
Ideal individual
|
|
The physical space that an individual actively defends
|
Territory
|
|
A theoretical circumstance where an individuals choose, and occupy, habitat of highest suitability
|
Ideal free distribution
|
|
A single essential nutrient or other resource that most limites an organisms growth
|
limiting resource
|
|
A simple model that describes the rate of an enzyme reaction relative to the concentration of some limiting substrate
|
Michaellis-Menten kinetics
|
|
THe set of points in resources availability along which reproductive rate exactly equals mortality rate
|
Zero net growth isocline
|
|
The per capita negative effect of a predator on it's victim population
|
Capture efficiency
|
|
The per capita effect of converting a single prey item on increasing the predator population
|
Conversion efficiency
|
|
A physical location that prey can go to escape predation
|
Refugia
|
|
Rate of victim capture by a predator as a function of victim abundance
|
Functional response
|
|
Per capita growth rate of predator population as a function of victim abundance
|
Numerical response
|
|
Functional response is prey capture linearly correlated with prey abundance
|
Type I
|
|
Functional response is mostly correlated with prey abundance, but tapers off to an upper asymptote due to prey saturation
|
Type II
|
|
Functional response is limited by prey saturation, but begins with a sigmoidal shape due to inefficient prey capture at very low prey abundance ( such as due to prey switching or a lack of search image)
|
Type III
|
