Conservation-induced extinction is where efforts to save endangered species lead to the extinction of other species. This mostly threatens the parasite...

Cretaceous–Paleogene (K–Pg) extinction event, formerly known as the Cretaceous-Tertiary (K–T) extinction event, was the mass extinction of three-quarters of...

The Holocene extinction, also referred to as the Anthropocene extinction or the sixth mass extinction, is an ongoing extinction event caused exclusively...

In ecology, extinction debt is the future extinction of species due to events in the past. The phrases dead clade walking and survival without recovery...

Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member...

Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid...

this threshold will ultimately lead to the extinction of that parasite in that population. Facilitation processes increase the extinction threshold, making...

De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct...

biodiversity is to maintain ecological function to prevent ecological extinction. Examples of species and subspecies that are extinct in the wild include...
