“…The two other bat species feed mainly on Moraceae (especially Ficus spp.) and Urticaceae (Mikich 2002;Passos et al 2003;Passos and Graciolli 2004). The families Urticaceae and Moraceae have several pioneer species, such as Cecropia pachystachya and Ficus dendrocida (Lorenzi 1992;.…”

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.

“…In addition, spring and summer likely correspond to periods of higher food availability in the south of Brazil. While there is no phenological information in the literature about the diet of A. fimbriatus in these regions, it is known that the abundance of insects is higher in spring and summer (Fabián et al 1990), which are consumed by Artibeus as part of their diet (Passos et al 2003;Passos & Graciolli 2004).…”

Reproductive biology of Artibeus fimbriatus Gray 1838 (Chiroptera) at the southern limit of its geographic range. Biota Neotropica. 16(4): e20160231. http://dx.doi.org/10.1590/1676-0611- BN-2016-0231 Abstract: Bats of the Phyllostomidae family exhibit different reproductive patterns in Neotropical regions and the strategy adopted depends on the regional climate. Here we studied the reproductive biology of Artibeus fimbriatus at the southern limit of their distribution in Brazil. This region has no rainy season, and the climate is characterized by high temperatures and variable photoperiods. We examined 129 A. fimbriatus females over several months, and used histological procedures where necessary in order to determine whether bats were pregnant. Females exhibited a long reproductive period and were pregnant from June until February. The reproduction events were found to be dependent on the photoperiod, but independent of annual accumulated precipitation. Our results show that at the southern limit of their distribution, A. fimbriatus exhibit seasonal-dependent reproductive patterns, with parturition events occurring during spring and summer, in which the days are longer and temperature is warmer.Keywords: Phyllostomidae; Photoperiod; Reproduction; Seasonal. Biologia reprodutiva de Artibeus fimbriatus Gray 1838 (Chiroptera) no limite sul de sua distribuição geográficaResumo: Os morcegos Phyllostomidae apresentam diferentes padrões reprodutivos no Neotropico e a estratégia adotada depende do clima regional. Neste trabalho nós estudamos a biologia reprodutiva de A. fimbriatus no Brasil, na região que determina o limite sul de sua distribuição geográfica, onde não há estação chuvosa e o clima é caracterizado por variações na temperatura e fotoperíodo. Nós examinamos 129 fêmeas de A. fimbriatus e utilizamos procedimentos histológicos, quando necessário, para classificar as fêmeas como prenhe ao longo dos meses. As fêmeas exibem um longo período reprodutivo e estão grávidas de junho até fevereiro. Nossos resultados mostram que as fêmeas de A. fimbriatus apresentam uma estratégia reprodutiva que é dependente da sazonalidade com os nascimentos ocorrendo quando os dias são mais longos e a temperatura é maior (primavera e verão), no limite sul de sua distribuição geográfica.

“…This particular feature could be seen as indicative of a wide feeding flexibility, allowing adaptations to different situations of food supply, since observations of food consumption during food abundance shows a clear preference for fruit from the families Cecropiaceae and Moraceae (Fleming, 1986;Passos et al, 2003). However, when fruits are scarce, animals end up using a more generalist feeding strategy, eating a variety of available species, including protein sources like insects (Passos and Graciolli, 2004).…”

Energy reserves of Artibeus lituratus (Chiroptera: Phyllostomidae) in two areas with different degrees of conservation in Minas Gerais, Brazil

Forest fragmentation associated with the expansion of human development is a phenomenon that occurs worldwide. Studies reveal that there have been both a decline in species diversity and a decrease in Neotropical bat population size because of habitat loss. The aim of this study was to investigate whether human action has been affecting the food availability to wildlife species, which could impact the storage of body energy reserves. For this purpose, fruit-eating bats (Artibeus lituratus) were collected in two areas in Minas Gerais state, Brazil. The concentrations of plasma glucose, as well as glycogen, lipids and protein in liver in muscles were performed, in addition to adipose tissue weight and carcass fatty acids. Our results indicate that fat reserves were significantly lower in most tested tissues (muscle of the hindlimbs, breast muscles, adipose tissue and carcass) in animals collected in the region with a higher degree of human disturbance. The other parameters showed no significant differences in the groups collected at different locations. In conclusion, we suggest that human action on the environment may be affecting the storage of body fat energy reserves of this species during the autumn, particularly in metropolitan region areas of Belo Horizonte, MG -Brazil, requiring special attention to the species conservation.Keywords: bats, glucose, metabolism, forest fragmentation. Avaliação das reservas energéticas em Artibeus lituratus (Chiroptera: Phyllostomidae) em áreas com diferentes graus de conservação em Minas Gerais ResumoA fragmentação florestal associada à expansão do desenvolvimento humano é um fenômeno que ocorre em todo o mundo. Estudos revelam que vêm ocorrendo tanto uma diminuição da diversidade de espécies quanto uma diminuição no tamanho das populações de morcegos neotropicais em função da perda de habitat. Com o objetivo de comparar o armazenamento das reservas energéticas em duas áreas com diferentes graus de conservação, morcegos frugívoros da espécie Artibeus lituratus foram coletados durante o outono de 2009 em duas áreas no Estado de Minas Gerais, Brasil. Foram determinadas as concentrações de glicose plasmática e de glicogênio, proteína e lipídio hepáticos e musculares, além das concentrações lipídicas do tecido adiposo e ácidos graxos totais da carcaça. As reservas lipídicas apresentaram concentrações significativamente menores na maior parte dos tecidos testados (músculo das patas posteriores, músculo peitoral, tecido adiposo e carcaça) nos animais coletados na região menos preservada. Os outros parâmetros não apresentaram diferenças significativas nos grupos coletados nos diferentes locais. Em conclusão, pode-se inferir que a ação humana sobre os ambientes pode estar afetando o armazenamento de reservas energéticas corporais lipídicas de machos dessa espécie, particularmente em áreas da região metropolitana de Belo Horizonte-MG, Brasil, durante o outono.Palavras-chave: morcegos, glicose, metabolismo, floresta fragmentada.
