Albinismo em zorrilho, Conepatus chinga (Mammalia, Carnivora, Mephitidae). O

Abstract

The present report describes a case of albinism in Conepatus chinga in a countryside area of Uruguay, thus enhancing disclosure about color mutation of Neotropical mammals.

FIRST RECORD OF PIEBALDISM IN Lycalopex gymnocercus (CARNIVORA, CANIDAE) IN THE PAMPA BIOME, SOUTHERN BRAZIL

“…In Southern Brazil, some cases of pigmentation anomalies in wild mammals have already been reported, for instance, in rodents, such as Delomys dorsalis (Rodentia, Cricetidae; Cademartori & Pacheco 1999) and Dasyprocta azarae (Rodentia, Dasyproctidae) (Oliveira 2009a), primates Alouatta guariba clamitans (Primates, Atelidae) (Fortes & Bicca-Marques 2008), cervids Mazama gouazoubira (Artiodactyla, Cervidae) (Oliveira 2009b), carnivores Conepatus chinga (Carnivora, Mephitidae) (Mello et al 2016), and marsupials Didelphis sp., (Didelphimorphia, Didelphidae) (Abreu et al 2013). However, for wild canids, the only record in the literature is for a leucistic Crabeating Fox Cerdocyon thous (Carnivora, Canidae), observed in the northwestern region of Brazil, Caatinga Biome, in the Agricultural Sciences campus of the Universidade Federal do Vale do São Francisco, located in the rural zone of the municipality of Petrolina, state of Pernambuco (Oliveira et al 2019).…”

“…Probably, there are many cases of chromatic mutation in wild mammals that were not reported yet in the literature (Abreu et al 2003, Lucati & Lopez-Baucells 2016. However, the disclosure of such cases in the vertebrate fauna became important since it may cause behavioral implications on aberrant colored individuals, as well as interfere in the breeding success (Abreu et al 2013, Aximoff & Rosa 2016, Mello et al 2016. Color aberrations, also called pigmentation anomalies, can result from both genetic and environmental causes.…”
