First Record of Coloration Abnormality in the Fur of Pteronotus Fulvus Bat (Chiroptera, Mormoopidae)

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

“…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.…”
