Abstract Narrow-mouthed frogs (Anura: Microhylidae) are globally distributed and molecular
data suggest the rapid evolution of multiple subfamilies shortly after their origin. Despite …

Vocal sacs are among the most conspicuous features of anurans and are particularly striking
in casque-headed treefrogs (Hylidae: Hylinae: Lophyohylini) with their wide array of …

Intraspecific chemical communication in frogs is understudied and the few published cases
are limited to externally visible and male-specific breeding glands. Frogs of the family …

The most ventral muscles of the head (the mm. submentalis, intermandibularis, and
interhyoideus) provide support to the gular region and lift the buccal floor during ventilation …

Sexual dichromatism, where males and females of the same species differ in coloration, is
best studied in diurnal animals. Nocturnal animals such as frogs do not seem good …

Ancestral character-state reconstruction is a powerful method in phylogenetics that can be
applied to elucidate the evolutionary history of secondary sexual characters. Here, we …

The vocal sacs of frogs are elastic structures responsible for the circulation of air during
vocalization, amplifying the sounds produced by these animals during multimodal …

The diversity of organisms can be studied at the cellular level. Cytological data related to
specific organisms can provide valuable information for their classification. One such …

Communication often mediates social interactions, including reproduction, defense, and
competition. In anurans, vocal sacs are used in communication during interactions, and they …

RESUMO O gênero Trachycephalus atualmente contém 18 espécies de pererecas e
notabiliza-se por abrigar representantes com e sem co-ossificação dermal craniana e por …
