“…Niceforo’s big-eared bat, Trinycterisnicefori , is an insectivore (Reis et al 2013, 2017). The diagnostic characteristics of the species include: its small size, with an adult head-body length of 51–58 mm; forearm of 35–41 mm; faintly tricolored dorsal hairs, with a darker base and tip; ventral fur dark; ventral margin of the nasal leaf horseshoe merging gradually with the upper lip, chin with a pair of dermal pads arranged in a V shape, without a central papilla; face and anterior orbital region of the cranium not inflated (Reis et al 2013, 2017).…”

Niceforo’s big-eared bat, Trinycterisnicefori (Sanborn, 1949), is a monotypic species which has been recorded in a number of Brazilian states, but has a disjunct distribution in this country. This study presents the first record of T.nicefori in the Brazilian state of Maranhão. The specimens were collected in the municipalities of Godofredo Viana and Cândido Mendes, in fragments of the Amazon forest. One male (forearm: 38.00 mm, weight: 6 g) and one female (39.68 mm, 8 g) specimens were collected. The specimens presented chestnut-colored fur, and a chin with a pair of dermal pads arranged in a V-shape, without a central papilla. The COI gene sequences were plotted in the BOLD Systems platform, which confirmed the morphological identification of the species, with a 99.1% similarity in the male, and 99.4% in the female to existing sequences. This record extends the known distribution of T.nicefori in Brazil by approximately 310 km to the most eastern part of the Amazon Biome.

“…This can explain why few records of these species were observed. The majority of our roadkill records is from A. lituratus (46%), a frugivore phyllostomid adapted to explore open areas and to move across great distances (Passos & Passamani 2003, Barros et al 2006, Menezes et al 2008, Reis et al 2012.…”

Road and Landscape Features That Affect Bat Roadkills in Southeastern Brazil

et al. 2017

The most studied impact on road ecology is roadkill, however, there is little information about the relations between highways and specific groups like bats. This study intended to identify the species of bats roadkilled and to evaluate the existence of temporal fluctuation between the roadkill rates, specific stretches of the road with higher rates, and characteristics of the road/landscape that may influence those rates. We encountered at least nine bat species among 65 roadkills (most Phyllostomidae), which comprise a subgroup of the local fauna that presents ecologic features that make them susceptible to being hit, especially Artibeus lituratus. The medium roadkill rate was of 0.01 individuals/km/day of monitoring, and there was no significant temporal variation. We identified five hotspots through special 2D HotSpot Identification Analysis. The selection of theoretical models through Generalized Linear Models showed that roadkill occurrence has a positive relation with vehicular traffic and negative relation with presence of marginal pasture and forests. As the major part of records was of species that are tolerant to human-disturbances, the increase in traffic consequently affected a higher number of bats capable to explore the area occupied by the road. The presence of native forest close to the road can lead to a decrease of animals hit by vehicles, once it offers more resources and favorable habitats, which reduces the need for bats to cross the roads for foraging. On the other hand, many species that necessarily depend on areas sheltered by trees for shelter, and do not possess the ability to fly long distances do not occur in open areas such as pastures. In this context, we suggest that the main measure of mitigation regard bat species would be the traffic control through speed limit, especially on the roadkill hotspots areas.

“…Devido ao seu modo de deslocamento único entre os mamíferos, este grupo propicia a conexão entre fragmentos que compõem a matriz paisagística de diversos ambientes, auxiliando na manutenção do fluxo gênico vegetal entre diferentes áreas (Costa et al, 2006;Mendes et al, 2009;Reis et al, 2012). Apesar disso, poucos são os estudos que abordam a composição das assembleias de morcegos em áreas com diferentes níveis de alteração nos ambientes de Restinga no Brasil (e.g., Oprea et al, 2009).…”

ResumoDados sobre a composição da mastofauna de Restinga do Brasil são escassos, sobretudo no que se refere à quiropterofauna. Este estudo teve por objetivo analisar a composição da assembleia de morcegos em um ambiente de Restinga alterada no sul do Brasil. As amostragens foram realizadas no município de Jaguaruna, litoral sul de Santa Catarina, entre os anos de 2006 a 2016. Os morcegos foram capturados com redes de neblina instaladas ao nível do solo. Para descrever a estrutura da assembleia de morcegos, foram utilizados atributos de riqueza, abundância e frequência de ocorrência. Foram capturados 514 indivíduos de duas famílias, oito gêneros e 14 espécies. A curva de acumulação de espécies não evidenciou tendências à estabilização. Artibeus lituratus, Sturnira lilium e Artibeus fimbriatus foram classificadas como frequentes. Myotis nigricans foi a única espécie pouco frequente, e as demais foram consideradas raras no estudo. Embora os sítios amostrados apresentem altos níveis de alteração, os resultados obtidos evidenciam que esses locais ainda abrigam uma fauna de morcegos representativa dos ambientes costeiros do Brasil. Assim, os resultados reforçam a necessidade de ações no sentido de minimizar os efeitos deletérios que as pressões antrópicas vêm exercendo sobre os remanescentes de Restinga.Palavras-chave: inventário, impactos antrópicos, quiropterofauna, Santa Catarina, ambientes costeiros. AbstractData on mammals in Brazilian Restinga are scarce, especially on chiropterans. This study aims to analyze the composition of bat assemblages in a degraded environment of Restinga in southern Brazil. The samplings were carried out in the municipality of Jaguaruna, southern coast of the Santa Catarina state, from 2006 to 2016. Bats were captured in mist nets at understory layer. Richness, abundance and frequency were considered in order to describe the bat assemblage structure. We captured 514 individuals from two families, eight genera and 14 species. Species accumulation curve did not show tendency to asymptote. Artibeus lituratus, Sturnira lilium and Artibeus fimbriatus were classified as frequent species, Myotis nigricans was the unique species considered less frequent and all other species were classified as rare in the study. Although the sampling sites show high levels of anthropic influence, the data obtained indicate that both areas shelter a representative bat fauna of coastal environments in Brazil. Thus, the results reinforce the need of actions to diminish deleterious effects from anthropic pressure in Restinga remnants.
