Population Growth

demographic parameter

statistical measures used to describe a population's characteristics and how they change over time

clutch size

The number of offspring one female produces in one reproductive cycle

cohort

Group of all individuals sharing a statistical factor (such as age or developmental stage)

density-dependent factors

Depending on the local density of the population

density-independent factors

Not linked to the local density of the population

discrete developmental stage

Non-overlapping and structurally distinct growth stages. E.g. tadpoles are one discrete developmental stage and adult frogs are another

subjectively designated geographic rang

A parcel of land, the size of which is chosen without using standardized criteria. Picked at the discretion of the researcher

pulsed reproduction

a pattern of population growth in which all individuals of a species reproduce during a single, discrete, and often synchronized period

time-specific life table

a distribution of age classes during a single time period
