Herpetology Notes, volume 14: 903-906 (2021) (published online on 24 June 2021) Bromelicolous habit of three species of Rhinella Fitzinger, 1826 (Anura: Bufonidae) in Northeastern Brazil’s Atlantic Forest Ubiratã Ferreira Souza1,*, Alan Pedro de Araújo2,3, Alcina Gabriela Maria Medeiros da Fonsêca Santos1, and Marcos Jorge Matias Dubeux4 Understanding habitat types and how organisms bromeliads for breeding can still use them as shelter (i.e., make use of them, is crucial for identifying factors bromelicolous; sensu Peixoto, 1995). Bromelicolous that determine species distribution and community habit can be recurrent (e.g., Scinax pachycrus [Araújo composition (Kopp and Eterovick, 2006; Pittman et et al., 2020], Nyctimantis brunoi [Peixoto, 1995]) or al., 2014). The phytotelmata are plant structures that opportunistic – when the anuran uses this phytotelm accumulate rainwater (e.g., bromeliad tanks, tree holes, occasionally (Peixoto, 1995; Andrade et al., 2009). bamboo internodes, axils and floral bracts; see Kitching, Among the four genera of bufonids occurring in 2000). Such structures provide microhabitats for fungi, the Brazilian Atlantic Forest (Segalla et al., 2019), microalgae, and both invertebrate and vertebrate Dendrophryniscus Jiménez-de-la-Espada, 1870, animals (Maguire, 1971; Ramos et al., 2018, 2019). The Frostius Cannatella, 1986 and Melanophryniscus plants of the Bromeliaceae family are the most common Gallardo, 1961 have strong association with phytotelm phytotelm across the Neotropical region (Ulloa-Ulloa environments, including bromeligenous species (Cruz et al., 2017), being used for shelter, foraging and/or and Peixoto, 1982; Haddad and Prado, 2005; Kwet et reproduction (Pugliese et al., 2009; Nunes et al., 2012). al., 2005; Wells, 2007; Langone et al., 2008; Dias et al., Among Neotropical anurans, more than 168 known 2016; Sabagh et al., 2017). However, for more than 90 species use bromeliad phytotelm habitats (Peixoto, Rhinella species, information about the use of specific 1995; Tonini et al., 2020), of which >100 depend on habitats is still scarce, and in most cases, they are bromeliads for reproduction (i.e., bromeligenous; regarded as habitat generalists (Duellman and Trueb, Tonini et al., 2020). This number is increasing following 1994; Sabagh and Carvalho-e-Silva, 2008). Some species recent descriptions of new species (Sabagh et al., 2017; have terrestrial habits, whereas others demonstrate Vörös et al., 2017; Orrico et al., 2018; Folly et al., 2018; semiarboreal habits and are found in human-altered Dias et al., 2020). Nevertheless, species that do not use habitats, open areas, as well as in the interior and edges of forest remnants (Roberto et al., 2011; Dubeux et al., 2019; Frost, 2020). Herein, we report the bromelicolous habit of three species of Rhinella from the northern region of the Atlantic Forest, Brazil. 1 Laboratório de Estudos Herpetológicos e Paleoherpetológicos, Departamento de Biologia, Universidade Federal Rural de In the Estação Ecológica de Tapacurá (8.0368ºS, Pernambuco, Rua Dom Manoel de Medeiros s/n, Recife, 35.2018ºW; WGS84, 200 m elevation), municipality 52171-900 Pernambuco, Brazil. of São Lourenço da Mata, Pernambuco state, Brazil, 2 Departamento de Ecologia, Laboratório de Herpetologia e we found a Rhinella granulosa (Spix, 1824) adult Comportamento Animal, Universidade Federal de Goiás, Av. on 4 February 2018 (dry season) at 18:00 h; and two Esperança s/n, Goiânia, 74690-900 Goiás, Brazil.
