Item First record of albinism in a mustached bat (Chiroptera, Mormoopidae) from South America(2021-01-22) S. B. Leal, Edson; F. Ramalho, DanielChromatic alterations, including albinism, are rare in wild animals. In bats, at least 160 cases of albinism have been recorded in individuals from ten families. For Mormoopidae, a single case of albinism and two cases of piebaldism are known in the world. This paper documents the first case of albinism in Mormoopidae in South America, which represents the first record of pigmentation alteration in Wagner’s mustached bat, Pteronotus personatus (Wagner, 1843) throughout its range. We provide a discussion on the impacts of interaction in roosts on fitness and survival of albino individuals.- First record of albinism in a mustached bat (Chiroptera, Mormoopidae) from South America(2021-05) Silva Barbosa Leal, Edson; de Figueiredo Ramalho, DanielChromatic alterations, including albinism, are rare in wild animals.

Item Mobility of bats between caves: ecological aspects and implications for conservation and environmental licensing activities in Brazil(2021-08-17) Leal, Edson Silva Barbosa; Bernard, EnricoBats are highly mobile animals, moving rapidly over long distances. Detecting such movements is challenging, especially in cave areas, a commonly-used roost by bats. Brazil has a large number of caves and bat species, but details on bat mobility among caves is still poorly documented there. Such monitoring provides insights on the structuring and conservation of cave-dwelling communities, with possible legal implications for the environmental licensing in Brazil. Based on marking (2,490 bats captured; 2,142 marked) and recapture (35 events; 14 extra-site), here we present data on the mobility of mormoopid bats between two bat caves 15 km apart in northeastern Brazil. Sexual segregation between caves may explain mobility: one cave is likely a maternity roost; the other is a satellite cave used for copulae. Nomadic behavior due to seasonal distribution of resources in the semi-arid Northeastern Brazil cannot be ruled out. Based on the distance between the two caves, bats could potentially forage over an area of ~170,000 hectares, in a wider use of the landscape. Our data have implications for the conservation of bat species and their roosts, and contribute to a more evidence-based discussion of key concepts governing the environmental licensing of mining activities in Brazil.
