Sympatric occurrence of two species of Pseudopaludicola (Anura: Leptodactylidae) and first record of Pseudopaludicola jaredi Andrade, Magalhães, Nunes-de-Almeida, Veiga-Menoncello, Santana, Garda, Loebmann, Recco-Pimentel, Giaretta & Toledo, 2016 in the state of Maranhão, northeastern Brazil

“…Note duration lasts from 20.9-26.7 ms (mean 23.9; SD = 1.4), and note interval from 51.8-64.4 ms (mean 55.9; SD = 4.2). Bioacoustic data presented here ( Figure 2) were similar to those reported by Carvalho et al (2015a) for the populations of P. canga recorded in the municipality of Palmas, Tocantins state. Roberto et al (2013) described in the municipality of Ribeiro Gonçalves, Piauí state, located about 100 km of the Parque Estadual do Mirador, a species of Pseudopaludicola with trilled advertisement call that likely resembles that of P. canga.…”

“…2014). The large number of cryptic species along with the conservative morphology of the genus Pseudopaludicola makes difficult the accurate taxonomic identification based exclusively on morphological/morphometric features (VeigaMenoncello et al 2014;Carvalho et al 2015a;Andrade et al 2016). This leads to an underestimation of the true diversity within the genus , and makes it difficult to determine the real geographic distributions of the species.…”

“…Despite the cryptic pattern (Pansonato et al 2012;Carvalho et al 2015aCarvalho et al , 2015b, sympatric occurrence is commonly observed among species of the genus Pseudopaludicola (Giaretta & Facure 2009;Loebmann & Haddad 2010;Magalhães et al 2014;Andrade et al 2016). This indicates that the species differ minimally in how they use natural resources and breeding sites, and the advertisement call is one of the main prezygotic barriers to reproductive isolation between them (Loebmann & Haddad 2010;Pansonato et al 2012;Andrade & Carvalho 2013;Magalhães et al 2014;Carvalho et al 2015aCarvalho et al , 2015b. in syntopy at dusk (around 18:00-18:30 h) in a flooded field covered by emergent vegetation near the banks of the Itapecuru River.…”

“…Recordings were sampled at a rate of 44.1 kHz and a 16-bit resolution and analyzed with the software SoundRuler, version 0.9.6 (Bee 2004;Gridi-Papp 2004). The identification of P. canga was based on morphological characters (Giaretta & Kokubum 2003;Cardozo & Suarez 2012) and acoustic parameters (Carvalho et al 2015a). Due to low number of males sporadically vocalizing, it was not possible to record the calls P. jaredi.…”

Diet and morphological aspects of a population of Pseudopaludicola pocoto (Anura: Leptodactylidae) from Northeast Brazil

“…Diferenças no tamanho corpóreo de anfíbios pode ser atribuído à idade, taxa de crescimento ou longevidade (Otero et al, 2017). No entanto, espécies do gênero Pseudopaludicola apresentam elevada variação intraespecífica e valores morfométricos interespecíficos muito semelhantes (De-Carvalho et al, 2015b), o que possibilita a existência de diferentes populações dessas espécies em que pode ou não haver diferenças sexuais quanto ao tamanho do corpo. Quanto a diferentes aspectos biológicos, as espécies de Pseudopaludicola que ocorrem no nordeste brasileiro ainda são pobremente estudadas (Roberto et al, 2013).…”
