Note on bats (Mammalia, Chiroptera) in a Restinga area of Rio Grande do Norte, Brazil

Abstract

<p style="text-align: justify;">Atualmente, quarenta e uma espécies de morcegos são conhecidas para as restingas do Brasil. No entanto, a maioria dos estudos sobre morcegos das restingas são limitados às regiões sul e sudeste do Brasil, deixando a região nordeste com uma lacuna de conhecimento. O presente artigo apresenta dados sobre morcegos capturados em três áreas de restinga do município de Tibau do Sul, Rio Grande do Norte, levantados a partir de uma amostragem de curta duração. Redes de neblina para captura de morcegos foram armadas próximas ao solo e sobre o corpo d’água. Foram capturados 38 indivíduos de seis espécies de duas famílias: cinco Phyllostomidae e um Molossidae. O morcego <em>Carollia perspicillata</em> (Linnaeus, 1758) foi a espécie mais abundante. Apresentamos aqui a primeira lista de morcegos capturados em área de restinga para o Rio Grande do Norte.</p><p style="text-align: justify;"><strong>Palavras chave</strong>: Molossidae, Nordeste, Novo registro, Phyllostomidae, Tibau do Sul.</p><p style="text-align: justify;"><strong>Abstract</strong>: Currently, forty-one species of bats are known to occur in the restingas of Brazil. However, most studies on restingas’ bats are limited to the south and southeastern regions of Brazil, leaving the northeastern region with a gap of knowledge. The present article presents data on bats captured in three areas of restinga of the municipality of Tibau do Sul, Rio Grande do Norte, collected from a short-term sampling. Mist nets were used to capture bats near the ground and the water bodies. Were captured 38 individuals of six species and two families: five Phyllostomidae and one Molossidae. The bat <em>Carollia perspicillata</em> (Linnaeus, 1758) was the most abundant species. We present here the first list of bats captured in the restinga area for the Rio Grande do Norte State.</p><p style="text-align: justify;"><strong>Key words</strong>: Molossidae, New record, Northeast, Phyllostomidae, Tibau do Sul.</p>

Bats in a restinga area in Sergipe, Northeastern Brazil

“…In addition, frugivore bats of the Phyllostomidae family are predominant in studies with mist nets in the Neotropical region (Bergallo et al, 2003;Nogueira et al, 2010). The same pattern was also observed in other restinga areas (Carvalho et al, 2009;Oprea et al, 2009;Luz et al, 2011;Soares et al, 2018) as a reflection of the sampling method and the availability of fruits in the areas.…”

“…Carollia perspicillata, A. lituratus, A. planirostris, and D. cinerea were the most captured species in this study, being abundant in restinga areas (Oprea et al, 2009;Nogueira et al, 2010;Luz et al, 2011;Gomes et al, 2016;Soares et al, 2018). These species occur in a variety of habitats, from more structured forests to degraded areas and plantations (Bernard, 2002;Passos et al, 2003), and have high ecological flexibility because they are able to explore a wide variety of resources (Mikich, 2002;Passos et al, 2003).…”

“…Despite the increase in the number of studies with bats in this environment in recent years (Bôlla et al, 2017), most of these are concentrated in the south and southeast regions of the country in the states of Rio de Janeiro (Cerqueira et al, 1990;Pessôa et al, 2010;Luz et al, 2011;Gomes et al, 2016), Espírito Santo (Luz et al, 2009;Oprea et al, 2009), Santa Catarina (Carvalho et al, 2009;Bôlla et al, 2017), and Paraná (Fogaça & Reis, 2008). In the northeast of the country, studies with this group in restingas have only been carried out in Paraíba (Campos et al, 2018), Rio Grande do Norte (Soares et al, 2018), and Sergipe (Rocha et al, 2017).…”

“…Some of these studies corresponded to a rapid survey with a small sampling effort in different habitats (Luz et al, 2009;Gomes et al, 2016;Rocha et al, 2017;Soares et al, 2018), and most of them revealed a low efficiency of bat capture in the rest-ISSN On-Line: 1807-0205 ISSN Printed: 0031-1049 ISNI: 0000-0004-0384-1825 inga areas (e.g., Luz et al, 2009Luz et al, , 2011Oprea et al, 2009;Nogueira et al, 2010;Gomes et al, 2016). Although the majority of species registered in this environment are generalist, the limitation of resources such as food and shelter in the restinga influences the lowest rates recorded (Nogueira et al, 2010), reflecting the lower densities for the group (Luz et al, 2011).…”

First record of Macrophyllum macrophyllum (Schinz, 1821) in Brazilian mangroves, with comments on bat diversity in this ecosystem

“…In the latter ecosystem, also spread along the Brazilian coast and frequently occurring in association with mangroves (Souza et al 2008), the diversity of insectivorous bats (17 spp. ; Nogueira et al 2010;Rocha et al 2017;Soares et al 2018) is similar to that reported here. However, the knowledge on the functional role played by the several trophic groups while using both these ecosystems is very limited (Nogueira et al 2010;Hogarth 2015).…”
