Abstract Temperature affects the rate of biochemical and physiological processes in amphibians, influencing metamorphic traits. Temperature patterns, as those observed in latitudinal and altitudinal clines, may impose different challenges on amphibians depending on how species are geographically distributed. Moreover, species’ response to environmental temperatures may also be phylogenetically constrained. Here, we explore the effects of acclimation to higher temperatures on tadpole survival, development, and growth, using a meta-analytical approach. We also evaluate whether the latitude and climatic variables at each collection site can explain differences in species’ response to increasing temperature and whether these responses are phylogenetically conserved. Our results show that species that develop at relatively higher temperatures reach metamorphosis faster. Furthermore, absolute latitude at each collection site may partially explain heterogeneity in larval growth rate. Phylogenetic signal of traits in response to temperature indicates a non-random process in which related species resemble each other less than expected under Brownian motion evolution (BM) in all traits, except survival. The integration of studies in a meta-analytic framework allowed us to explore macroecological and macroevolutionary patterns and provided a better understanding of the effects of climate change on amphibians. clines distributed Moreover constrained Here survival development metaanalytical meta analytical approach conserved faster Furthermore nonrandom non random BM (BM metaanalytic analytic

O Cerrado é uma savana tropical que abriga uma anurofauna muito diversa, sendo estimado de 209 espécies à 271 espécies conhecidas, das quais a metade (51%) são endêmicas. Neste trabalho, apresentamos o inventário da anurofauna da Reserva Extrativista Lago do Cedro (RELC), noroeste do estado de Goiás. Ao todo, registramos 36 espécies de anuros, distribuídas em cinco famílias, das quais cinco espécies são endêmicas do Cerrado. A alta riqueza de espécies encontrada pode ser explicada pela heterogeneidade de habitats, promovida pelas diferentes fitofisionomias dentro da unidade de conservação. A riqueza de espécies e a representatividade por família apresentam valores semelhantes aos encontrados em outras taxocenoses no Cerrado, com a anurofauna local formada por espécies generalistas e de ampla distribuição. As famílias com maior diversidade de espécies foram Hylidae e Leptodactylidae, padrão frequentemente encontrado nas assembleias neotropicais. A RELC é uma importante unidade de conservação do Cerrado, servindo de abrigo para populações de anuros, sendo representativa da diversidade de anfíbios no bioma, e apresentando localização estratégica devido a posição central com relação a áreas de preservação na bacia do Araguaia.

The Cerrado is a tropical savannah with a diversified anuran assemblage, with 209 to 271 known species, of which approximately 51% are endemic. In this study, we report results of an anuran survey performed in the Extractivist Reserve of the Lago do Cedro, located in the northwestern region of the state of Goiás, Brazil. In this area, we recorded 36 anuran species, distributed in five families, from which five species are Cerrado endemics. This high species richness found in the Extractivist Reserve of the Lago do Cedro could be explain by the different vegetational types within the reserve boundaries that promote a high local heterogeneity. Species richness and representativeness per family are similar to other assemblages reported for different areas in the Cerrado domain, being the local anuran assemblage composed by generalist and widely distributed species. The families Hylidae and Leptodactylidae are the most diversified in the studied area, a common pattern found in neotropical assemblages. The Extractivist Reserve Lago do Cedro is an important area for Cerrado conservation because of the anuran diversity and geographic location, which allows the connection among other protected areas within the Araguaia basin.
