Range extension of the Peale's Free-tailed Bat Nyctinomops aurispinosus (Molossidae) in Brazil

Abstract

Abstract:There is a lack of knowledge of the biology and distribution of Nyctinomops aurispinosus. Herein, we report the southernmost record of this species, from the city of Curitiba (25° 25

Species Richness, Abundance and Functional Diversity of a Bat Community along an Elevational Gradient in the Espinhaço Mountain Range, Southeastern Brazil

“…To obtain functional diversity metrics, we combined an abundance matrix with a trait matrix. Data on the following traits were extracted from the literature (Norberg and Rayner, 1987;Eisenberg and Redford, 1989;Gannon et al, 1989;Bianconi et al, 1996Bianconi et al, , 1998Emmons and Feer, 1997;Norberg, 1998;Bernard and Fenton, 2003;Meyer et al, 2008;Reis, 2013) and used for all species: weight, feeding guild, aspect ratio (ratio between wing span and width) and type of shelter used ( Supplementary Table S1). Rao's quadratic entropy is a measure of ecological community diversity (Rao, 1982) and is based on the proportion of the abundance of species present in a community and a measure of dissimilarity among them.…”

First record of the Vulnerable bat Furipterus horrens (Cuvier, 1828) (Chiroptera: Furipteridae) in the state of Paraná, southern Brazil

“…Thus, it was expected that this species would occur in Paraná. With this new record, the number of bat species known to Paraná has now increased to 70 (Bianconi et al 2009, Scultori et al 2009, Passos et al 2010, Moratelli et al 2011, Carvalho et al 2014. Although recently there has been an increase in the number of bat records in the Atlantic Forest of Paraná, a number of factors such as fewer long-term monitoring schemes and the routine use of mist nets for recording species have been detrimental to improving the knowledge on Paraná's bat diversity (Varzinczak et al 2016).…”

Notes on the geographic range and distribution of two free-tailed bat species (Chiroptera, Molossidae) in Costa Rica

“…Despite growing information on the geographic distribution of free-tailed bat species in the Neotropics (e.g. Gregorin and Taddei 2000, Pineda et al 2008, Baker et al 2009, Bianconi et al 2009, Feijó et al 2010, Gregorin et al 2011, Rodríguez-Herrera et al 2014, Medina-Fitoria et al 2015, González-Terrazas et al 2016, there are still many distributional gaps, creating the illusion that some of the species are rare, patchily distributed, or absent in some areas (Reid 2009). This rarity seems to be a direct consequence of the difficulty in capturing these bats with traditional methods, such as placing mist nets at ground level (Reid 2009), and more complex inventory techniques, such as acoustic recordings that are not always available to all tropical bat researchers.…”
