Cytogenetic studies in six species of Scinax (Anura, Hylidae) clade Scinax ruber from northern and northeastern Brazil [PDF]

Genetics and Molecular Biology, 2015
Scinax species are still underrepresented in cytogenetic studies, mainly with respect to populations from northeastern and northern Brazil. In this study, we provide new chromosomal information on Scinax boesemani, S. camposseabrai, S.

DNA barcode reveals candidate species of Scinax and Ololygon (Anura: Hylidae) in Atlantic Forest [PDF]

Genetics and Molecular Biology, 2022
Molecular species delimitation methods are efficient tools to identify species, including the discovery of new taxa and cryptic organisms, thus being useful to biodiversity studies.

Using molecular taxonomy to identify Scinax (Anura: Hylidae): New distribution records and implications for Neotropical biodiversity [PDF]

Genetics and Molecular Biology
Traditional morphological identification is challenging in large and diverse groups, such as the genus Scinax, which comprises about 78 species, and molecular taxonomy emerges as an efficient tool for species delimitation.

Identification of the taxonomic status of Scinax nebulosus and Scinax constrictus (Scinaxinae, Anura) based on molecular markers [PDF]

Brazilian Journal of Biology, 2020
The validation of many anuran species is based on a strictly descriptive, morphological analysis of a small number of specimens with a limited geographic distribution.

Simultaneous Detection of Missing Amphibians and Their Fungal Pathogen in a Biodiversity Hotspot Using eDNA. [PDF]

Mol Ecol
ABSTRACT Since the 1970s, striking amphibian declines in population abundances and presumed extinctions have been recorded globally. The chytrid fungus Batrachochytrium dendrobatidis (Bd) is one of the key drivers of these declines. To investigate the potential role of Bd in the decline of Brazil's amphibians, we first used eDNA metabarcoding to survey

Host Genus and Habitat Use Shape the Distribution of Batrachochytrium dendrobatidis Lineages in a Hyper‐Diverse Tropical Amphibian Community [PDF]

Ecol Evol
Anthropogenic change has facilitated the spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) in Brazil's Atlantic Forest, where two Bd lineages (Bd‐GPL and Bd‐Brazil) co‐occur. We successfully genotyped 252 Bd‐positive samples from a diverse amphibian assemblage spanning aquatic and terrestrial habitats and found that Bd lineage ...

An experimental test of the importance of isolated trees for frog diversity in tropical landscapes. [PDF]

J Anim Ecol
We performed the first experimental test of the importance of isolated trees for biodiversity. Our results provide evidence that isolated trees contribute to increasing total species richness and community abundance of anurans in artificial ponds, making local communities more similar to those found in ponds near forest edges.

Anurans or Mice: What is the Best Food Item for Young and Adults of Bothrops jararacussu (Lacerda, 1884) in Captivity? [PDF]

Zoo Biol
We use Bothrops jararacussu as a model to introduce three different prey items (mice, exotic anuran – bullfrog and native anurans) in captivity. Our experiments indicated that native anurans could be an interesting food alternative to B. jararacussu and other Bothrops species with an ontogenetic diet in captivity.

Amphibian Chytrid Fungus Infection Influences Calling Investment in Male Brown Toadlets. [PDF]

Ecol Evol
The sublethal effects of infection and disease on male advertisement behaviour remain poorly understood. Here we show that male brown toadlets infected with the amphibian chytrid fungus produce calls with more pulses compared to uninfected males. The association we report supports the terminal investment hypothesis and has the potential to impact host ...

Wind farm noise negatively impacts the calling behavior of three frogs in Caatinga dry forests. [PDF]

PLoS ONE
Acoustic signals play a fundamental role in the lives of anurans. With the increasing prevalence of wind farms in Caatinga ecosystems, our goal was to assess whether the noise generated by this energy source poses a threat to anuran communication.
