Evidence for the evolution of male and female cardinals’ plumage colouration being affected by both natural and sexual selection [PDF]

BMC Ecology and Evolution
The evolution of sexually selected traits, such as colouration, has been the object of considerable research. Among birds, plumage colouration is highly variable and includes some of the most exuberant signals.

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

DNA, 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
