“…Moreover, we lack bat diversity estimators for the majority of urbanized areas, due to inappropriate sampling designs. For phyllostomid bats, the minimum sampling effort suggested is of 1000 mist net captures at a given site (Bergallo et al 2003). Among the bat surveys based on field work which provided abundance data, we found that 63% sampled less than 500 bats.…”

Bats in urban areas of Brazil: roosts, food resources and parasites in disturbed environments

Urbanization is a widespread intense land use that generally results in biodiversity decline. Among the taxa capable to adapt to urban landscapes, bats are particularly ubiquitous. Brazil has one of the world's largest diversity of bat species and one of the highest urbanization rates of the world. Yet, few studies have synthesized the biology of bats in urban environments, especially in Brazil. To fill this gap, we systematically reviewed the published scientific literature on the bat fauna found in urban areas of Brazil. The knowledge of urban bats is still incipient and heterogeneously spatially distributed, mostly concentrated in the southeastern region of the country. The assembled list of 84 urban species, of which nineteen are new species records for urban areas (including one new family), represents 47% of the bat richness registered in the country. Thirty-one bat species (37%) were captured exclusively inside forest fragments. Moreover, we provide information on the resources used within the urban matrix by summarizing the roosting sites for 38 bat species, as well as 31 plants consumed by at least twelve bat species. Regarding parasitological aspects, we listed eleven zoonotic parasites hosted by 27 bat species and discussed their potential to become a public health threat. Likewise, we considered the different features linked to urbanization, including impacts on immunity, body condition and susceptibility to acquiring parasites, as possible bat conservation issues. Finally, we defined an agenda for bat studies in urban areas of Brazil.

“…Besides the accumulation curves, the number of captures should also be considered when analyzing the completeness of the sampling effort. According to Bergallo et al (2003), at least 1000 captures are necessary to sample the majority of phyllostomid species in Atlantic Forest areas. Thus, despite presenting a high richness, a larger sampling period and additional captures could also increase the number of species registered in PECB.…”

Carlos Botelho State Park (PECB) is a large remnant of Atlantic Forest in Southeastern Brazil, with more than 37,000 ha. As its bat fauna is still unknown, we performed the first bat survey on PECB, to provide data on the distribution, natural history and taxonomy of the species. Fieldwork was conducted monthly, from October 2016 to September 2017. Captures were made using ground-level mist-nets (39600 m2.h), canopy mist-nets (2017.5 m2.h) and searches for roosts (42 hours).We captured 412 bats from 34 species of Phyllostomidae, Molossidae and Vespertilionidae. A total of 11 species were captured only in ground-level mist-nets, five in canopy mist-nets, and seven in roosts. Dermanura cinerea Gervais, 1856, Eptesicus taddeii Miranda, Bernardi & Passos, 2006, Glyphonycteris sylvestris Thomas, 1896 and Lampronycteris brachyotis (Dobson, 1879) are rare on surveys conducted in the Atlantic Forest of São Paulo and were captured in canopy mist-nets. Micronycteris schmidtorum Sanborn, 1935 and Molossus currentium Thomas, 1901 constitute the first record for the state of São Paulo, and were captured in canopy mist-nets and roosts, respectively. The species richness registered for PECB surpasses other surveys conducted in Atlantic Forest localities that use only ground-level mist-nets. Our results reinforce the importance of employing mixed capture methods, such as elevated mist-nets and searches for roosts.

“…A UC com maior esforço de captura teve um maior número de registros de espécies de morcegos ameaçadas. O uso de um longo esforço de captura pode favorecer a aproximação da amostragem da riqueza real de uma localidade (Voss & Emmons 1996, Bergallo et al 2003, Stevens 2013, podendo amostrar mais espécies, inclusive aquelas consideradas raras. Unidades de Conservação que não foram amostradas ou que foram pouco amostradas devem ser prioridade para os inventários de biodiversidade (Oliveira et al 2017).…”

“…No Estado do Rio de Janeiro existem 48 UCs de Proteção Integral e 53 de Uso Sustentável nas esferas federais, estaduais e municipais. É um estado que pode ser considerado um dos melhores amostrados em relação aos morcegos (Bergallo et al 2003, Stevens 2013, porém ainda existem áreas que possuem lacunas de conhecimento sobre ocorrência desses animais , como exemplo, as regiões do Médio Paraíba e Centro-Sul (Dias et al 2010).…”
