Population and Natural resources

Population Ecology

The study of interactions between organisms and their environment, focusing on how individuals in a population interact and how the population interacts with its surroundings.

Population Size

The total number of individuals of the same species living and interbreeding in a specific area.

Quadrat Sampling

A method used to study immobile organisms like plants, involving counting individuals in a sample area to estimate the total population size.

Mark-Recapture Method

A technique used to study animal populations that move, where marked individuals are recaptured to estimate the total population size.

Census

A systematic collection of information from individuals in a population, providing a complete enumeration of the population members.

Population Density

The number of individuals within a specific area or volume, measured as the population size as a percentage of the total land area occupied.

Population Dispersal

How individuals in a population are distributed in space at a given time, with patterns including uniform, random, and clumped dispersion.

Population Growth

The increase in the number of individuals in a population, measured by the population growth rate as the percentage change in population size over a specified period.
