A time-calibrated phylogeny of the diversification of Holoadeninae frogs.

The phylogeny of the major lineages of Amphibia has received significant attention in recent years, although evolutionary relationships within families remain largely neglected. One such overlooked group is the subfamily Holoadeninae, comprising 73 species across nine genera and characterized by a disjunct geographical distribution. The lack of a fossil record for this subfamily hampers the formulation of a comprehensive evolutionary hypothesis for their diversification.

Data collected by citizen scientists reveal the role of climate and phylogeny on the frequency of shelter types used by frogs across the Americas.

Shelters are microhabitats where animals rest and hide. These microhabitats can be used from short daily periods to long-term estivation or hibernation. Environmental conditions and the phenotypical characteristics of the animal drive habitat selection in relation to shelters.

Description and evolution of the larynx of the Physalaemus olfersii species group, with remarks on the laryngeal anatomy of the P. cuvieri clade (Amphibia: Anura: Leiuperinae).

The anuran larynx is an organ of great evolutionary interest because it impacts male reproductive success in courtships. However, little is known about the diversity of the larynx's anatomy, evolutionary history and systematics importance. Here, we describe and compare the anatomy of the larynx of 10 Physalaemus species of the P.

Review of bioacoustical traits in the genus Physalaemus Fitzinger, 1826 (Anura: Leptodactylidae: Leiuperinae).

Given the importance of acoustic communication in intraspecific recognition during mating activity, acoustic traits have been widely used to clarify the taxonomy of anurans. They have been particularly useful in the study of taxa with high morphological similarity such as the Neotropical genus Physalaemus. Here, we reviewed the acoustic repertoires of the species of Physalaemus based on homology hypotheses in order to make comparisons more properly applicable for taxonomic purposes.

First description of sound emission of Rhaphiptera affinis Thomson, 1868 (Cerambycidae: Lamiinae: Pteropliini).

Cerambycidae is one of the largest families of beetles, containing about 38,000 described species (Tavakilian Chevillotte 2018). In most species of this family, adults possess a stridulatory device that allows them to produce squeaking sounds (Wang 2017). In the subfamilies Prioninae and Parandrinae, individuals stridulate by rubbing their ridged hind femora against elytral margins (Švácha Lawrence 2014).

A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae).

A new species of the anuran genus Euparkerella is described from a rainforest area in the state of Rio de Janeiro, southeastern Brazil. Morphologically, the species resembles E. brasiliensis and E.
