“…Similar results were obtained in Cerrado in Minas Gerais by Knegt et al (2005) and in Mato Grosso do Sul by Ferreira et al (2010). In the present study, there was a tendency for diversity to be lower at the more disturbed sites, although diversity at site 2 was similar to that of the disturbed sites, due to the marked abundance of C. perspicillata and A. lituratus, which together accounted for 56% of the individuals captured.…”

in forest remnants of the Cerrado savanna of eastern Mato Grosso, Brazil. Biota Neotrop. 13(2): http://www.biotaneotropica.org.br/v13n2/en/abstract?inventory+ bn03313022013Abstract: In the state of Mato Grosso, studies aiming to investigate the diversity and richness of bats are still scarce. In the present study, the chiropteran fauna of eastern Mato Grosso (Brazil) was investigated at four sites representing the Cerrado savanna biome with different degrees of anthropogenic impact, in the municipality of Nova Xavantina. Surveys were conducted between January and December, 2010, with a total of 48 nights of mist-netting. A total of 423 bats were captured, representing 25 species distributed in five families. A greater abundance of individuals was recorded at all sites during the rainy season, with considerable variation being observed over the course of the year in species richness and composition, and the abundance of bats. Species richness and bat abundance were higher in the better preserved habitats in comparison with the impacted areas. The timing of foraging activities appeared to vary among the specimens and there was a progressive increase in activity until 19:30 h, with a marked decline after 22:30 h. The ecological diversity (Shannon-Wiener index) of the bat community within the study area was H' = 2.37. Keywords: Chiroptera, conservation, species richness, diversity.

Biota Neotrop. 13(2): http://www.biotaneotropica.org.br/v13n2/pt/abstract?inventory +bn03313022013Resumo: No estado de Mato Grosso, os estudos visando investigar a diversidade e riqueza de morcegos ainda são escassos. Neste estudo, a quiropterofauna da região leste mato-grossense foi investigada por meio de capturas em quatro áreas remanescentes de Cerrado com diferentes índices de conservação, no município de Nova Xavantina. As capturas ocorreram de janeiro a dezembro de 2010, totalizando 48 noites de amostragem. Foram capturados 423 indivíduos, distribuídos em 25 espécies e cinco famílias. Os quatro ambientes apresentaram maior abundância na estação chuvosa e, ao longo dos meses e entre as estações do ano a composição, riqueza e abundância de morcegos variaram. As áreas mais preservadas apresentaram maior riqueza e maior abundância de morcegos em relação às áreas degradadas. Foi possível verificar que o horário de forrageamento variou entre os espécimes capturados, ocorrendo um pico crescente de atividade até às 19:30h e uma redução acentuada por volta das 22:30h. A diversidade calculada pelo índice de Shannon-Wiener (H') para as áreas foi de H'=2,37. Palavras-chave: Chiroptera, conservação, riqueza, diversidade. 237 Bats in the Cerrado savanna of Mato Grosso

“…Although we observed a bimodal reproductive pattern for S. lilium as it is known from lowland locations (Stoner 2001;De Knegt et al 2005), reproduction was concentrated in a shorter period in the highlands and the first (main) and the second reproduc- tive peaks were less distinct compared with the pattern registered for other neotropical leaf-nosed bats, like carolliines and glossophagines in the lowlands of rain forests, whose reproductive peaks last longer (Mello and Fernandez 2000;Zortéa 2003;Tschapka 2005). As an example, most pregnant female S. lilium at a study site in the lowlands of Costa Rica were registered in a 5-month period (Stoner 2001), whereas pregnancy was concentrated in only 2 or 3 months in our study area in the mountains.…”

Ambient temperature is more important than food availability in explaining reproductive timing of the bat Sturnira lilium (Mammalia: Chiroptera) in a montane Atlantic Forest

Reproduction of bats is determined by a suite of endogenous and exogenous factors. Among exogenous influences, special attention has been given to the influence of food availability. However, in highland forests, severe decreases in temperature during the cold and dry season may also play an important role. In the present study we tested the influence of ambient temperature and food availability on the timing of reproduction in the frugivorous bat Sturnira lilium (E. Geoffroy, 1810). We conducted a 15-month mist-netting sampling in a mountain area of the Brazilian Atlantic Forest during which time we assessed the bats' diet through fecal samples, monitored fruit production of the main food plants, and recorded variations in ambient temperature. Sturnira lilium fed almost exclusively on Solanaceae. Similarly to the lowlands, reproduction was bimodal, but reproductive season tended to be shorter in the highlands and peaked in the warmer months of the year. Overall, 44% to 53% of the reproductive pattern was explained by variations in ambient temperature, while the relationship with food availability was nonsignificant. We conclude that variations in ambient temperature in tropical mountains may be a stronger selection pressure than food availability in determining reproductive timing of bats.Résumé : La reproduction des chauves-souris est déterminée par une série de facteurs endogènes et exogènes. Parmi les facteurs exogènes, on a porté une attention particulière à l'influence de la disponibilité de nourriture. Cependant, dans les forêts des terres hautes, les grandes chutes de température durant la saison froide et sèche peuvent aussi jouer un rôle important. Dans notre recherche, nous testons l'influence de la température ambiante et de la disponibilité de la nourriture sur le calendrier de la reproduction chez la chauve-souris frugivore Sturnira lilium (E. Geoffroy, 1810). Nous avons fait une échantillonnage pendant 15 mois dans une région montagneuse de la Forêt atlantique brésilienne; nous avons déter-miné le régime alimentaire des chauves-souris par prélèvement de fèces, suivi la production de fruits des principales plantes nourricières et enregistré les variations de la température ambiante. Sturnira lilium se nourrit presque exclusivement de Solanaceae. Comme dans les basses terres, la reproduction est bimodale, mais la saison de reproduction tend à être plus courte dans les terres hautes et elle atteint un sommet durant les mois plus chauds de l'année. Les variations de la température ambiante expliquent globalement 44 % à 53 % du patron de reproduction, alors que la relation avec la disponibilité de nourriture n'est pas significative. Nous en concluons que dans les montagnes tropicales, les variations de la température ambiante peuvent exercer une pression de sélection plus grande que la disponibilité de nourriture dans la dé-termination du calendrier de reproduction des chauves-souris.[Traduit par la Rédaction]

“…Two G. soricina also emerged from that shelter. This nectar feeding bat has been usually found in Brazilian urban areas (Bredt and Uieda 1996;Silva et al 1996;De Knegt et al 2005;Uieda and Chaves 2005;Bredt et al 2012), where they harbor in attics and basements. On the other hand, A. caudifer is more adapted to medium and large forest fragments (Reis et al 2003), as is the case of regions surrounding the Serra do Itaberaba.…”

The present study provides a record of the bat fauna captured in Guarulhos, state of São Paulo, Brazil, between February and November 2011. The capture sessions were carried out using mist nets set on trails, around and above streams and lakes, near built areas and around livestock. After a total effort of 26,208 m2.h, we recorded 17 bat species belonging to Phyllostomidae (13 species), Vespertilionidae (3) and Molossidae (1). Sturnira lilium (73 captures), Artibeus fimbriatus (69), and A. lituratus (59) were the most abundant species, corresponding to 57.8% of all captures. Some information about shelters was also commented. This paper is the first to report Molossops neglectus for Guarulhos.
