Assessing the Genetic Health and Conservation Value of an Introduced Urban Population of a Critically Endangered Parrot

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Non‐native species can be introduced to novel environments such as cities via wildlife trade. These populations may have conservation value—particularly if they are of a species threatened in its native range. Genetic tools can help assess the fitness of introduced populations by indicating if they are (1) suffering the consequences typically ...
