Reproductive activity and population structure of Myotis nigricans (Schinz, 1821) (Chiroptera: Vespertilionidae) in the southern Brazil

Among mammals, bats present the greatest diversity in reproductive strategies. In this study we analyzed reproductive and population characteristics of Myotis nigricans over one year in a temperate region in Brazil. We carried out the samplings in an anthropic roost, in Pedras Grandes municipality,...

Among mammals, bats present the greatest diversity in reproductive strategies. In this study we analyzed reproductive and population characteristics of Myotis nigricans over one year in a temperate region in Brazil. We carried out the samplings in an anthropic roost, in Pedras Grandes municipality, Santa Catarina state. We captured bats monthly with mist nets installed at the roosts exits and identified the captured individuals according to sex, reproductive condition and age. There was greatest number of females than males. Population size was estimated from 569 to 1050 individuals. Births occurred mainly from September to January, with more than one pregnancy event along the year, evidencing a seasonal and bimodal polyester pattern. The reproductive period of M. nigricans in southern Brazil is similar to the records made in other regions. Despite of it, there is no pattern along its distribution range. © SAREM, 2018. 2020-05-15T20:46:14Z 2020-05-15T20:46:14Z 2018 Artigo https://repositorio.inpa.gov.br/handle/1/15681 10.31687/SAREMMN.18.25.2.0.20 pt_BR Volume 25, Número 2, Pags. 399-406 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Mastozoologia Neotropical
