Ecological Succession and Species Vocabulary

This set of flashcards covers key vocabulary related to ecological succession, species classification, and conservation concepts.

Succession

A sequence of changes in a community after a disturbance.

Primary Succession

The development of an ecosystem in an area with no soil or vegetation following a severe disturbance.

Secondary Succession

The process of recovery in a community where soil remains after a disturbance.

Pioneer Species

The first organisms, such as plants and microbes, that colonize a new terrestrial environment during primary succession.

Climax Community

A stable, self-sustaining community resulting from ecological succession that can withstand disturbances.

Biodiversity Hotspots

Areas with significant biodiversity that are under threat from human activities.

Ecotourism

Travel focused on adventure, culture, and nature appreciation in natural environments.

Keystone Species

A species with a disproportionately large effect on its ecosystem, which can include top predators or vital plant species.

Extinction

The permanent loss of a species from the planet, which can occur naturally over time.

Native Species

Organisms that naturally occur in a specific region, having evolved there without human influence.

Non-native Species

Organisms introduced to an ecosystem outside their natural range due to human actions.

Indicator Species

Species that provide insight into the health of an ecosystem.

Speciation

The process through which new species arise through evolution.

Species

Groups of organisms that can interbreed and produce living, fertile offspring.

Extirpation

The complete removal or local extinction of a species from a specific area.

Endangered Species

Species at imminent risk of extinction.

Threatened Species

Species that are declining in numbers and may become endangered soon.

Exotic Species

Non-native species introduced to a new environment.

Invasive Species

Non-native organisms that thrive in new areas, often due to a lack of natural predators.

Poaching

Illegal activities involving the hunting or harvesting of wildlife that violate conservation laws.

Endemic Species

Species confined to a specific geographic area.
