First record of anomalous coloration for Eptesicus taddeii (Vespertilionidae) in the Atlantic Forest, South Brazil

Abstract

Piebaldism is characterized by the absence of melanin in certain areas of the body due the lack of melanocytes as a result of genetic mutations, and which occurs only locally. This study reports the first record of piebaldism for Eptesicus taddeii, a species of bat, endemic to the Atlantic Forest in the South Region of Brazil.

Registro de desorden cromático en Trachops cirrhosus (Spix, 1823) (Chiroptera: Phyllostomidae) en la Amazonia del Ecuador

“…The inter or intraspecific relationships of individuals with this chromatic disorder are considered to be unaffected of because it does not increase the risk of predation in juveniles stages, being possible to observe them in subadult or adulthood stages (Souza et al 2013, Tello et al 2014, Zalapa et al 2016, Hernández-Aguilar & Santos-Moreno 2018, Borloti et al 2019, Pereira et al 2022, or in individuals they have reached their reproductive stage, such as gravid or lactating females, and males with scrotal testicles (Hernández-Mijangos 2009, Sánchez-Hernández et al 2010, Marín-Vásquez et al 2010, García-Morales et al 2012, López-Wilchis & León 2012, Zalapa et al 2016, Biassi et al 2017, Aguilar-López et al 2021, Genelhú et al 2022. This hypothesis is supported by the specimens of Trachops cirrhosis reported in this study was a subadult individual.…”

“…Reports of hypopigmentary disorders in bats have been increasing for more than 20 years in the Neotropics (Uieda 2000, Lucati & López-Baucells 2016, Zalapa et al 2016, more frequently in the last decade (Souza et al 2013, Rocha et al 2013, Tello et al 2014, Romano et al 2015, Ruelas et al 2016, Zalapa et al 2016, Mejía-Quintanilla et al 2017, Biassi et al 2017, Nascimento et al 2018, Hernández-Aguilar & Santos-Moreno 2018, Zortéa & Silva 2018, Hernández-Canchola et al 2019, Borloti et al 2019, Aguilar-López et al 2021, Salas et al 2021, Aguilar-López et al 2021, Genelhú et al 2022, Santos-Moreno & Hernández-Aguilar 2022, Pereira et al 2022. Nevertheless, South American region presents an important bias in terms of reports of color disorders in bats, especially in the Amazon basin (Lucati & López-Baucells 2016).…”

“…These hypopigmentary disorders have been reported in several bat species of the Molossidae, Mormoopidae, Phyllostomidae, and Vespertilionidae families in many Neotropical countries such as Argentina, Brazil, Colombia, Costa Rica, Guatemala, Mexico, Peru, Puerto Rico and Venezuela (Geiger & Pacheco 2006, Ruelas et al 2016, Medina & López 2010, Marin-Vasquez et al 2010, Idoeta et al 2011, López-Wilchis & León 2012, Rocha et al 2013, Olarte-González et al 2014, Tello et al 2014, Trujillo & Barahona 2014, Romano et al 2015, Mello-Torres & Salazar-Candelle 2016, Zalapa et al 2016, Mejía-Quintanilla et al 2017, Hernández-Aguilar & Santos-Moreno 2018, Escobar-Anleu & Mora 2018, Reis et al 2019, Borloti et al 2019, Pereira et al 2022, Santos-Moreno & Hernández-Aguilar 2022. The manifestation of these disorders is unusual in wild mammals (Abreu et al 2013), and various authors associate it to ecological and genetic factors, the isolation of populations and inbreeding, or exposure to chemical substances or radiation (Bensch et al 2000, Moller et al 2013, Beninato et al 2020.…”
