Abstract
Unusual colorations are rare in Didelphis, but records are important to understand genetic aspects of the species. Albino individuals have a total absence of pigmentation throughout the body (skin and hair) and have eyes without traces of pigmentation, but with a red or pink color. We draw attention to the first two confirmed records of albinism in white-eared opossum (Didelphis albiventris) and their karyotype. This is the first record of albinism in D. albiventris in Northeastern Brazil. This calls attention to develop future research on the genetic diversity and the risk of inbreeding and consanguinity in populations of this region.
期刊介绍:
Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
