Anuran amphibians show acoustic communication as a fundamental component of reproduction. Hylodidae and Cycloramphidae are two anuran families that have an unclear phylogenetic relationship, but are consistently recovered close together. Today, those families have been nested with Alsodidae and Batrachylidae, forming the clade named Neoaustrarana. In this group, hylodids and cycloramphids…
The unprecedented loss of biodiversity and the imminent threats of climate and environmental changes are among the most important challenges faced by humanity. Biodiversity continues to decline worldwide, mainly in response to urban and agriculture expansion over natural areas. In addition, climate change is projected to commit over one-third of the Earth's animal and plant species to ext…
The Dry Diagonal (DD) contains a number of environments including the Caatinga and Cerrado that span over 1/3 the area of Brazil, as well as the Chaco of northern Argentina. Because of its perceived lower biodiversity for many taxa than in better known biomes such as the Amazon basin and the Atlantic forest, evolutionary processes in the DD have received much less attention from biologis…
The study of the evolutionary processes that originate phenotypic diversity is one of the most important endeavours in biology because it can offer insights into the process of adaptation in natural populations. Colouration patterns are remarkable traits for studying the mutational mechanisms underlying phenotypic diversity and how these affect patterns of evolutionary change. Among verte…
Due to ecological features amphibians are particularly sensitive to environmental changes. Global amphibian declines and associated extinction risk have been worrying specialists and more studies on amphibian diversity are necessary. The Atlantic Forest occurs in a large latitudinal range and exhibits climatic diversity associated to the topographic complexity. Few studies have been evalu…
The degradation of natural ecosystems by human action has generated an unprecedented crisis in the biota of the planet. Besides the environmental deterioration caused by man, through fragmentation, degradation, or complete destruction of ecosystems, there are other serious problems, such as the introduction of exotic species, diseases, pollution / contamination, climate change, and the sy…

Ceratophryidae is a Neotropical frog family composed of species with adaptations to semi-arid environments. In this family, Ceratophrys is the most diverse and widely distributed genus. There are eight species that are distributed from the north of Venezuela to the center of Argentina. The genus is divided into two clades, of which the clade called C. aurita is composed of C. aurita, C. c…

The genus Scinax contains 129 species divided in two clades: the S. catharinae clade and the S. ruber clade. The S. ruber clade harbors the S. duartei species complex, that comprises four treefrog species endemic of Brazil. Two of these species, S. duartei and S. caldarum, are morphologically very similar species that have never been compared directly in taxonomic works. The lack of a …
The genus Scinax is currently the most specious genus of Hylidae. It contains 126 species divided into two large clades: the S. ruber clade and the S. catharinae clade. The S. ruber clade species were recovered in eight species groups in the most inclusive phylogenetic study of Scinax (Araujo-Vieira et al. in prep.); one of these groups is the Scinax auratus group, composed of eight descr…

Alterations caused by humans, including climate change and habitat loss, are profoundly affecting the biosphere. Therefore, advancing knowledge in areas directly applicable to conservation biology is crucial, particularly for highly affected geographic regions, taxonomic groups, and species of conservation concern. Fundamental requirements include accurate taxonomic delineation and unders…
The tribe Scinaxini has been a focal point of phylogenetic analyses to uncover the relationships among its diverse species. The recent comprehensive phylogenetic study by Araujo-Vieira et al. (2023) has recovered the monophyly of Scinaxini and recognized three well-supported genera: Julianus, Ololygon, and Scinax. This context provides an evolutionary context for the study of the diversit…
The larynx of anurans is a cartilaginous structure that houses the vocal cords. The sound is produced by the vibration of the vocal cords and associated cartilages as the air accumulated in the lungs is expired and moves through the larynx into the buccal cavity. The larynx is of great importance during the reproductive period of anurans, because it is the organ that produces the calls re…
Anuran species of Thoropa miliaris group (T. megatympanum, T. miliaris, T. saxatilis, T. taophora; family Cycloramphidae) live in the Atlantic forest and campo rupestre, in rocky environment like waterfalls, rocky seashores, low flow streams, and humid rocky outcrops. The Thoropa miliaris group is monophyletic and present many lineages, many of them apparently without gene flow, even when…
Amphibians are particularly susceptible to environmental changes and infectious diseases. They are associated with microorganisms producing bioactive molecules that act as a barrier to the colonization of pathogenic agents. Variations in the structure of the amphibian skin microbial communities and their metabolic products (i.e., microbiomes) can have a direct influence on the ability of …
