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.

巴西东北部卡廷加地区的第一只白化白耳负鼠：Didelphis albiventris（Lund，1840 年）的白化病记录

不同寻常的颜色在Didelphis中非常罕见，但记录下来对了解该物种的遗传方面非常重要。白化个体全身（皮肤和毛发）完全没有色素沉着，眼睛没有色素沉着的痕迹，但呈红色或粉红色。我们提请注意白耳负鼠（Didelphis albiventris）中首次出现的两例白化病确诊记录及其核型。这是巴西东北部白耳负鼠白化病的首次记录。这要求今后对该地区种群的遗传多样性以及近亲繁殖和近亲结婚的风险开展研究。

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.
