#Rf online skin palmas set Patch
It had a patch of white hair above the right eye ( Figure 2), while the rest of the body was normally colored. The forearm of the specimen measured 45.4mm for and its body mass weighted 14g.
Mist nets were placed in the understory, in the canopy and in clearings and edges of the forest and were kept open for six hours after sunset during three consecutive nights of sampling.Īn adult male E. The vegetation is characterized as Araucaria Pine Forest, a phytophysiognomy of the Atlantic Forest found in the Southern Brazilian Plateau (states of Rio Grande do Sul, Santa Catarina and Paraná) at altitudes above 500-600 meters ( MMA, 2010). The climate of the region is of the Cfb type - temperate climate, according to the Köppen classification, with an average temperature in the coldest month below 18☌ (mesothermal) with cool summers, and an average temperature in the hottest month below 22☌ and without a defined dry season ( Wrege et al., 2012). The bat was captured during sampling for an inventory at Estação Ecológica Municipal Capivara I, in the municipality of Campina do Simão, state of Paraná, Brazil (-25☀4’30.3”S -51☄9’37.9”W), in February 2020 ( Figure 1).įigure 1 Map showing the location of the collection site for the specimen in Estação Ecológica Municipal Capivara I, municipality of Campina do Simão, state of Paraná, Brazil. Here we report the first record of piebaldism in the species Eptesicus taddeii Miranda, Bernardi & Passos 2006, observed in an bat captured in the Atlantic Forest in the South Region of Brazil ( Bernard et al., 2013). Trapido and Crowe (1942) reported the case of three individuals of Eptesicus fuscus (Palisot de Beauvois, 1796) with white spots on the body, gray-colored fur and irregular spots of three different shades. In Brazil there are cases of anomalous coloring for the families of Molossidae, Vespertilionidae and Phyllostomidae ( Uieda, 2000 Geiger and Pacheco, 2006 Lucati and López-Baucells, 2016 Miranda et al., 2010 Rocha et al., 2013 Souza et al., 2013 Treitler et al., 2013) and these data are growing ( Borloti et al., 2019).Īnomalous coloration has been previously reported for the genus Eptesicus Rafinesque. In bats, most cases of pigmentation disorders have been documented mainly in the families Vespertilionidae and Phyllostomidae ( Lucati & López-Baucells, 2016 Velandia-Perilla et al., 2013 Zortéa & Silva, 2018), probably because they are the largest and best studied families ( Hernández-Aguilar & Santos-Moreno, 2018). Piebaldism is similar to leucism but differs in that the development of melanocytes is interrupted only locally ( Lucati & López-Baucells, 2016).Ĭases of chromatic disorders have been reported in different groups of mammals in different regions of the world ( Abreu et al., 2013 Lucati & López-Baucells, 2016 Mahabal et al., 2019 Velandia-Perilla et al., 2013).
Individuals with this anomaly have a variable distribution of white spots on the body, however, the eyes are not affected. Piebaldism has recently been classified as the absence of melanin in certain areas of the body caused by the lack of melanocytes as a result of genetic mutations affecting the follicles of the skin and hair ( Abreu et al., 2013 Lucati & López-Baucells, 2016). There are still disagreements regarding the correct terminology to describe these disorders, especially for those related to hypopigmentation ( Zalapa et al., 2016), which has generated incompatibility among published data. E-mail: /0000-0002-7199-2452.Īnomalous coloration in mammals can occur due to an excess or deficit in melanin production in certain areas or throughout the entire body ( Acevedo and Aguayo, 2008 Caro, 2005 Ortolani, 1999 Zortéa & Silva, 2018).
