Visual communication in Hypsiboas curupi (Anura: Hylidae) at Parque Estadual do Turvo, southern Brazil

Distribution extension of Hypsiboas curupi Garcia, Faivovich & Haddad, 2007 (Amphibia: Anura: Hylidae) for Rio Grande do Sul, southern Brazil

“…Garcia et al (2007) observed a few males calling in secluded locations, from twilight until several hours after nightfall, in vegetation or partially immersed in water. Lipinski et al (2012) and Zanella et al (2013) recorded this species along a stream, calling from the vegetation, confirming its preference for this type of habitat.…”

Ecologia e história natural de Hypsiboas curupi (Anura, Hylidae): um anfíbio endêmico do sul da Mata Atlântica

“…Small population sizes are apparently more common in stream-dwelling amphibians in the Atlantic Forest (Almeida-Gomes et al, 2014) than in species in lentic habitat. The population in this study is one of the few currently known in Brazil (see Iop et al, 2009;Lucas and Marocco, 2011;Lucas and Garcia, 2011;Lipinski et al, 2012;Bastiani and Lucas, 2013). Fragmentation and isolation of the interior Atlantic Forest, expansion of hydroelectric projects in the region, and land and soil conversion for agricultural (Câmara, 2003;Bonai et al, 2009;Ternus et al, 2011) and silvicultural projects (Machado et al, 2012) may promote isolation of H. curupi populations.…”

“…The use of vegetation as calling sites is common in Hylidae species . The preference of H. curupi males for twigs and leaves may be due to favorable sound propagation (Bastos and Haddad, 1999) and increased visual communication (Lipinski et al, 2012) associated with this type of substrate. Such choices may reflect the evolutionary history of the species and their success in attracting females and defending territory (Greer and Wells, 1980;Martins et al, 1998;Bastos and Haddad, 1999;.…”

“…Some species of this group have been recently described ; Antunes et al, 2008;Kwet, 2008), and difficulty with species identification suggests a complex taxonomy. Ecological aspects of H. curupi are not well described, and data are limited to descriptions of larvae, adult (male) vocalization , geographical distribution (Brusquetti and Lavilla, 2008;Iop et al, 2009;Lucas and Garcia, 2011;Zanella et al, 2012), behavior (Lipinski et al, 2012) and infectious diseases (Preuss et al, 2015). Hypsiboas curupi populations in Brazil are categorized as "vulnerable" according to the Official List of Brazilian Species Fauna Threatened by Extinction (MMA, 2014), and "endangered" by the List of Species of Threatened Fauna of Santa Catarina State (CONSEMA, 2011).…”

First record of visual displays in Scinax cardosoi (Anura: Hylidae)

“…Anuran visual communication has received more attention (2001) and Hartmann (2005). Several types of visual signals have been described in anuran species (e.g., Bertoluci 2002, Hartmann 2005, Giasson and Haddad 2006, Toledo 2007, Caldwell 2010, Barros and Feio 2011, Lipinski 2012, Caldart 2014, Furtado 2017 (Bokermann, 1968), (Lutz, 1925), (Cardoso andSazima, 1980), and(Cope, 1862). Two types of visual displays occur in the genus.…”
