Term
Population Ecology
Definition
The study of populations in relation to the environment, including environmental influence on population density and distribution, age structure, and variation in population size.
Term
Population
Definition
a group of individuals of a single species living in the same general area.
Term
Density
Definition
the number of individuals per unit area or volume
Term
Dispersion
Definition
the pattern of spacing among individuals within the boundaries of the population
Term
Mark recapture method
Definition
Traps are set to capture animals who are tagged by color or collar and then released
Term
Immigration
Definition
the influx of new individuals in a population
Term
Emigration
Definition
the movement of individuals out of a population
Term
Clumped Dispersion
Definition
individuals aggregated in patches (most common dispersion)
Term
Uniform Dispersion
Definition
Evenly spaced (results from direct interactions between individuals in a population)
Term
Random dispersion
Definition
occurs in the absence of strong attraction or repulsion among individuals of a populations or where key physical or chemical factors are relatively homogeneous across the study area
Term
Demography
Definition
study of the vital statistics of populations and how they change over time
Term
Cohort
Definition
a group of individuals of the same age, from birth to death (a way to construct a life table that measures survival pattern in a population)
Term
Survivorship curve
Definition
a way to graphically represent the life table; a plot of the proportion or numbers in a cohort still alive at each age
Term
Reproductive table
Definition
an age specific summary of the reproductive rates in a population
Term
Big Bang Reproduction (Semelparity)
Definition
Reproducing in a great amount and than die off. Can be observed in plants and animals (occurs when the survival rate for infant is low)
Term
Repeated Reproduction (Iteroparity)
Definition
Repeated process of reproduction in which the cycle continues annually (In a dependable environment)
