Bats of a varzea forest in the estuary of the Amazon River, state of Amapá, Northern Brazil

Abstract

Abstract:The varzea forests of the estuary of the Amazon River cover 25,000 km 2 within the states of Pará and Amapá . The mammals of those forests, especially bats, are still poorly known. Hence, the present study aimed at inventorying the bat species from three localities of a varzea forest in the estuary of the Amazon River. Between November and December 2013, we selected 18 sampling sites in the mouths of three tributaries of the Amazon River: the rivers Ajuruxí, Maracá , and Mazagã o. We set up ten mist nets (12 x 3 m) along a 150-m linear transect in each sampling site, in a total sampling effort of 38,888 m 2 .h. We captured 403 individual bats of 40 species and five families. We recorded the families: Phyllostomidae (n ¼ 31 species), Emballonuridae (n ¼ 6 species), Moormopidae (n ¼ 1 species), Vespertilionidae (n ¼ 1 species), and Thyropteridae (n ¼ 1 species). Carollia perspicillata, Artibeus planirostris, and Carollia brevicauda comprised 45% of the records. We also made the first record of Glyphonycteris daviesi for Amapá state, and captured rare species, such as Dicludurus albus and Macrophyllum macrophylum. Our results show that the varzea forest of the estuary of the Amazon River harbors high bat diversity, and, hence, conservation policies should be considered for the region. Those policies should encourage the responsible management of ac¸aí palm (Euterpe oleracea) and timber. They should also fight illegal timber exploitation that threatens the fauna and flora of those biodiverse forests.

Morcegos de floresta de várzea no estuário do Rio Amazonas, estado do Amapá, Norte do Brasil.http://dx.doi.org/10.1590/1676-06032015016814Resumo: As florestas de várzea do estuário do Rio Amazonas ocupam uma extensão 25. 000 km 2 , abrangendo os estados do Pará e Amapá. Os mamíferos destas florestas, especificamente morcegos ainda são pouco conhecidos. Este estudo visa apresentar uma lista de espécies de morcegos de três localidades em floresta de várzea no estuário do Rio Amazonas, contribuindo assim com o conhecimento da quiropterofauna desta fitofisionomia. Entre Novembro e Dezembro de 2013 foram selecionados 18 sítios de coletas na foz de três rios tributários do Rio Amazonas: Rio Ajuruxí, Rio Maracá e Rio Mazagão. Com o uso de dez redes de neblina (12 x 3 m) armadas ao longo de um transecto linear de 150 metros em cada sitio de coleta e totalizando um esforc¸o amostral de 38,888 m 2 . h capturamos 403 indivíduos distribuídos em 40 espécies e cinco famílias. As famílias registradas foram Phyllostomidae (n ¼ 31 espécies), Emballonuridae (n ¼ 6 espécies), Moormopidae (n ¼ 1 espécie), Vespertilionidae (n ¼ 1 espécie) e Thyropteridae (n ¼ 1 espécie). Carollia perspicillata, Artibeus planirostris e Carollia brevicauda compreenderam 45 % dos registros. Nó s documentamos o primeiro registro de Glyphonycteris daviesi para o estado do Amapá. Registramos também espécies raras como Dicludurus albus e Macrophyllum macrophylum...

Ecological aspects of artibeus lituratus e artibeus planirostris (Chiroptera, Phyllostomidae) in Cerrado environments, Mato Grosso - Brazil

“…Similar results were found in Cerrado environments in Mato Grosso do Sul, byFerreira et al (2010) andMartins et al (2014).In studies conducted in different localities in Brazil A. lituratus is the most abundant(Trajan 1984;Passos & Passamani 2003;Passos & Graciolli 2004;Bianconi et al 2006;Brusco & Tozato 2009;Araújo & Langguth 2010;Luz et al 2011; Bernardi & Steps 2012;Sato et al .2015). A. planirostris is considered a common species and maybe the dominant species in some localities(Gregorin et al 2011;Alho et al 2011;Martins et al 2011;Castro & Michalski 2015;Barros et al 2017).…”
