Multitrait adaptive evolution is shaped by factors such as phylogenetic and functional
constraints as well as the intensity and direction of selection. The tempo and mode of such …

Species of Brachycephalus has been having taxonomical issues due its morphological
similarity and genetic conservatism. Herein, we describe a new species of Brachycephalus …

Abstract The Brazilian Atlantic Forest harbors high levels of anuran diversity and endemism,
including several taxa restricted to small geographic ranges. Here, we provide a multilocus …

Altitudinal patterns in species richness vary among taxa and are shaped by the intrinsic traits
of different organisms and their response to environmental variables. We evaluated the …

Anurans of the genus Brachycephalus are among the smallest vertebrates in the world, due
to an extreme process of miniaturization. As an example of this process, Brachycephalus …

The structure of the skin may evolve rapidly during a biological invasion, for two reasons.
First, novel abiotic challenges such as hydric conditions may modify selection of traits (such …

Four species of pumpkin toadlets are currently recognized by the extreme condition of
hyperossification in the skull and vertebral column within the genus Brachycephalus. In …

Miniaturized amphibians of the genus Brachycephalus are phenotypically diverse. The
species of Brachycephalus have bufoniform or leptodactyliform Baupläne and any of three …

Brachycephalus bufonoides was described as a “variety” of B. ephippium based on two
specimens which 90 years later was considered full species. Besides its brief original …

The number of described species of Brachycephalus has rapidly increased in the last
decade (n= 22, which represents 56% of the total). Species of the genus Brachycephalus …
