Karyotype Organization of the Endangered Species Yellow Cardinal (Gubernatrix cristata) [PDF]

open access: yesDna, 2021
Karyotypic analyses have several applications in studies of chromosome organization, evolution, and cytotaxonomy. They are also essential to genome assembly projects. Here, we present for the first time the karyotype description of the endangered species yellow cardinal, Gubernatrix cristata (Passeriformes, Thraupidae), using conventional staining with

Behavioural Responses Are Associated With Mortality and Mobility After Reintroduction in the Endangered Yellow Cardinal

Ibis, 2023
Reintroductions are an important management tool for the conservation of threatened species. Personality or temperament of individuals is likely to influence survival in the reintroduction success of released individuals. We studied behavioural traits related to personality in the globally endangered Yellow Cardinal Gubernatrix cristata and analysed ...
