New records of Uroderma magnirostrum Davis (Mammalia, Chiroptera) from southeastern Brazil, with comments on its natural history

Abstract

ABSTRA ABSTRA ABSTRA ABSTRA ABSTRACT CT CT CT CT. . . . . Uroderma magnirostrum Davis, 1968 is reported from four new localities in southeastern Brazil, significantly extending its geographical distribution south and westward. A total of 12 adult specimens collected in areas of Caatinga and Atlantic Forest in the states of Minas Gerais, Espírito Santo, and Rio de Janeiro, including specimens from the new localities and museum specimens were examined. Females from southeastern Brazil were larger than males in all external measurements analyzed, but after univariate statistical analyses using corrected p values for multiple tests no significant sexual dimorphism was detected. Mean values obtained from this sample fall within the known range documented for the species in both external and cranial measurements, and are similar to those found in specimens from north and northeastern Brazil. The habitats of the new localities of U. magnirostrum in southeastern Brazil ranged from pristine and secondary forests to a small urban park. Uroderma magnirostrum is apparently a rare species in southeast Brazil, which corroborates most previous reports of populations of this bat at other localities.

Do wooded streets provide connectivity for bats in an urban landscape?

“…This species has been regularly reported to occur in urban areas in Brazil, possibly due to its opportunistic behavior (Galetti and Morellato 1994;Sazima et al 1994;Zortéa and Chiarello 1994;Bredt and Uieda 1996), suggesting it may have a certain tolerance to urbanization (Barros et al 2006). The majority of the bat species recorded in the present study were already found to occur in urban areas in Brazil (Reis et al 1993;Pedro et al 1995;Bredt and Uieda 1996;Silva et al 1996;Félix et al 2001;Bredt et al 2002;Esbérard 2003;Nogueira et al 2003;Passos and Passamani 2003). Bredt and Uieda (1996) state that A. lituratus, P. lineatus, and G. soricina all find food and roosts in urban habitats.…”

Small mammals (Chiroptera, Didelphimorphia, and Rodentia) from Jaíba, middle Rio São Francisco, northern Minas Gerais State, Brazil

“…Micronycteris sanborni and X. vieirai were exclusively sampled at this site, as were other more widespread species, like P. macrotis, P. kappleri, C. auritus, and Uroderma magnirostrum. Additionaly, almost 50% of the bat species reported here was found at this site, where abundant roosts and core plants in the diet of stenodermatines (e. g. Ficus and Cecropia) are available (Nogueira et al 2003). Since we conducted our last field activities in Jaíba, in 1995, extensive changes have been promoted in the landscape of this region, largely due to the continuity of the conversion of forests into agricultural plots.…”

“…This list has been very useful in the evaluation of the biological importance of Jaíba, but lacks methodological and ecological information from the original surveys, including a list of the voucher material available. Part of the material collected in Jaíba during the 1990s was listed by Tavares et al (2010) in a check list for the state of Minas Gerais, but more detailed information, including field observations, remain available only for a few taxa (Nogueira & Pol 1998, Nogueira et al 2003. In the most recent assessment of the bat diversity in northern Minas Gerais, Falcã o et al (2014) reported 22 species for the Mata Seca State Park, but no voucher material was prepared in this study.…”

Morcegos da região sul do Brasil: análise comparativa da riqueza de espécies, novos registros e atualizações nomenclaturais (Mammalia, Chiroptera)

“…Chama a atenção o número de ampliações de distribuições geográficas e novos registros (e.g. DIAS et al, 2003;NOGUEIRA et al, 2003;POL et al, 2003;GREGORIN et al, 2004;CAMARGO & FISCHER, 2005;BORDIGNON, 2005;AGUIAR et al, 2006;FABIÁN et al, 2006;MELLO & POL, 2006;MIKALUSKAS et al, 2006;MIRANDA et al, 2006bMIRANDA et al, , 2007aMIRANDA et al, , 2007bSODRÉ & UIEDA, 2006;WEBER et al, 2006WEBER et al, , 2007BERNARDI et al, 2007;GAZARINI & BERNARDI, 2007;LONGO et al, 2007;SCULTORI et al, 2009). Além dessas novas ocorrências, foram realizadas descrições de novas espécies para o Brasil: Xeronycteris vierai Gregorin & Diethfield, 2006, Thyroptera devivoi Gregorin, Gonçalves & Engstron, 2006 e Eptesicus taddeii Miranda, Bernardi & Passos, 2006(GREGORIN & DIETCHFIELD, 2006MIRANDA et al, 2006a).…”
