“…On the other hand, it has also been registered in calling activity throughout the year depositing the clutches in leaves above permanent water bodies (reproductive mode number 24, sensu Haddad and Prado, 2005) in moist forests. Although it is well known that the reproductive season in anuran communities is related to climatic factors (see Vaira, 2005;Zina and Haddad, 2006;Zank et al, 2010), the present study shows that domain characteristics, that are also associated with climatic factors, may not only be correlated to the duration of the reproductive season, but also act as a selective force on the reproductive mode exhibit by the species. This observation reinforces the ecological plasticity of D. minusculus.…”

Herein we present new occurrences of sites of Dendropsophus minusculus in Brazil adding information about reproductive biology and colour patterns of the species. Such information is fundamental for characterising the species that we believe has been neglected due to its morphological similarity with other congeneric species. Dendropsophus minusculus may be found in different morphoclimatic domains, being one of the most generalist species of the genus in this aspect. The species plasticity is not restricted to its occurrence, but also related to aspects of its reproductive biology, and we hypothesised that the latter feature could explain the wide geographical range of the species. We highlight the importance of further in-depth studies and the use of D. minusculus as a model to understand the historical events responsible for the current geographical distribution of the morphoclimatic domains in Brazil.Keywords: reproductive plasticity, polymorphism, taxonomy, Dendropsophus microcephalus species group. , 1971) (Hylidae, Dendropsophini) como espécie polimórfica e de ocorrência em distintos domínios morfoclimáticos O reconhecimento de Dendropsophus minusculus (Rivero ResumoNo presente estudo relatamos novos locais de ocorrência para Dendropsophus minusculus no Brasil e acrescentamos informações sobre a biologia reprodutiva e padrões de coloração da espécie. Essas informações são de fundamental importância para a caracterização da espécie, que acreditamos ter sido negligênciada em virtude de sua semelhança morfológica com outras espécies congenéricas. Dendropsophus minusculus pode ser encontrada em diversos domínios morfoclimáticos, sendo, neste aspecto, uma das espécies mais generalistas de seu gênero. A plasticidade da espécie não se restringe a sua ocupação territorial, mas também a aspectos relativos a sua biologia reprodutiva e especulamos que esta seja a razão de sua amplitude territorial. Destacamos ainda a importância de estudos mais aprofundados e o uso da espécie como modelo para o entendimento de eventos pretéritos responsáveis pela distribuição de domínios morfoclimáticos no Brasil.Palavras-chave: plasticidade reprodutiva, polimorfismo, taxonomia, grupo de espécies de Dendropsophus microcephalus.

“…Previous studies of P. minuta in regions of the subtropical zone located farther inland have indicated similar positive relationships between abundance or activity patterns and temperature (Santos et al, 2008). Likewise, Zank et al (2010) found that reproductive activity in P. minuta is influenced by temperature and rainfall but not by other climatic factors. In a broader context, it has been argued that in tropical latitudes the reproductive activity of amphibians is influenced primarily by rainfall (Aichinger, 1987), whereas in temperate regions, both rainfall and temperature seem to play a major role in amphibians' reproductive behavior (Zank et al, 2010).…”

Pseudis minuta is abundant in a variety of aquatic environments of the Pampa domain. Therefore, it can be considered a good model for testing hypotheses on environmental heterogeneity and the influence of climate on the activity of anurans. In this study, we examined the spatial distribution pattern of P. minuta in terms of microhabitats and the influence of abiotic factors on seasonal fluctuations in the abundance of this species. Samples were collected monthly from April 2008 to May 2009 in wetlands and coastal dunes in the Lagoa do Peixe National Park. A total of 112 specimens of P. minuta were collected, of which 45 were found in the wetland area and 67 in the dune area. The species showed seasonal fluctuation in abundance, and it was most abundant in months with higher temperatures (spring-summer). Pseudis minuta was mainly associated with aquatic vegetation, an expected pattern in terms of their morphological adaptations to this environment. Among the abiotic parameters analyzed, only the monthly mean temperature showed a significant correlation (p < 0.05; r = 0.67) with the abundance of P. minuta. We concluded that P. minuta is a generalist species with respect to microhabitat use and also that fluctuation in its population abundance is mainly associated with seasonal variation in temperature.Keywords: abundance, anuran, coastal plain, Lagoa do Peixe, spatiotemporal distribution.Padrão de atividade e uso de micro-habitat de Pseudis minuta Günther, 1858 (Anura, Hylidae) no Parque Nacional da Lagoa do Peixe, uma reserva da biosfera na região subtropical do Brasil ResumoPseudis minuta é uma espécie abundante em diferentes tipos de ambientes aquáticos do domínio Pampa. Por essa razão, essa espécie pode ser considerada um bom modelo para testar hipóteses relacionadas à heterogeneidade ambiental e à influência do clima sobre padrões de atividade em anuros. Neste trabalho, foi avaliado o padrão de distribuição espacial de P. minuta em termos de micro-habitats, além de se avaliar a influência de fatores abióticos nas flutuações sazonais da abundância dessa espécie. Coletas foram realizadas mensalmente, entre abril de 2008 e maio de 2009, em áreas úmidas e de cordões de dunas costeiras no Parque Nacional de Lagoa do Peixe. Um total de 112 indivíduos de P. minuta foi coletado, sendo 45 em áreas de banhado e 67 em área de dunas. A espécie apresentou flutuação sazonal na abundância, sendo mais abundantes em meses com temperaturas mais elevadas (primavera-verão). Pseudis minuta esteve associada principalmente à vegetação aquática, um padrão esperado em função de suas adaptações morfológicas a esse meio. Entre os parâmetros abióticos analisados, somente a temperatura média mensal apresentou correlação significativa (p < 0.05; r = 0,67) com a abundância de P. minuta. Foi possível concluir que P. minuta é uma espécie generalista com relação ao uso do habitat e que as flutuações na sua abundância populacional estão principalmente associadas à variação sazonal da temperatura.Palavras-chave: abundância, anuro, planí...

“…However, in subtropical regions -a region subjected to ecological pressure such as cold, frost, seasonality on temperature -a limited number of studies tested how ecological pressures in microhabitat scale affect the reproductive behavior of frog species (e.g. Zank et al, 2010;Huckembeck et al, 2012); for nest-building gladiator frogs, no study was found.…”

ABSTRACT. Male gladiator frogs of Hypsiboas Wagler, 1830 build nests on available substrate surrounding ponds and streams where female spawn eggs during the breeding period. Although gladiator frogs seem to show plasticity in the way they construct their nests, there is no study reporting if these species present preferences about microhabitat conditions for nest-building (mainly under subtropical climate). Predation pressure and environmental conditions have been considered major processes shaping the great diversity of reproductive strategies performed by amphibians, but microhabitat conditions should explain where to build a nest as well as how nest looks. This study aimed to test nest site selection for nest-building by Hypsiboas faber (Wied-Neuwied, 1821), determining which factors are related to nest site selection and nest features. The survey was conducted at margins of two permanent ponds in Southern Brazil. Habitat factors were evaluated in 18 plots with nest and 18 plots in the surrounding without nest (control), describing vegetation structure and heterogeneity, and substrate characteristics. Water temperature was measured inside the nest and in its adjacency. Nest features assessed were area, depth and temperature. Habitat characteristics differed between plots with and without nest. Microhabitat selected for nest-building was characterized by great vegetation cover and height, as well as shallower water and lower cover of organic matter in suspension than in plots without nest. Differences between temperature inside nest and in its adjacency were not observed. No relationship between nest features and habitat descriptors was evidenced. Results revealed that Hypsiboas faber does not build nests anywhere. Males seem to prefer more protected habitats, probably avoiding predation, invasion of conspecific males and inclement weather. Lack of differences between temperature inside-and outside-nest suggest that nest do not improve this condition for eggs and tadpole development. Nest architecture was not related to habitat characteristics, which may be determined by other factors, as nest checking by females before amplexus. Nest site selection should increase offspring survival as well the breeding success of Hypsiboas faber.

Machos de espécies de Hypsiboas Wagler, 1830 constroem ninhos no substrato disponível no entorno de corpos d'água; as fêmeas depositam os ovos no interior destes ninhos durante a reprodução da espécie. Embora estes machos apresentem plasticidade na escolha de sítios para construção dos ninhos, ainda não existem avaliações de preferências por condições específicas de microhabitat para a nidificação (principalmente em clima subtropical). A pressão de predação e as condições ambientais são consideradas os principais processos moldando a diversidade de estratégias reprodutivas em...
