In this paper, we provide new bioacoustic and distributional data on Bokermannohyla sapiranga, as well as additional comparative bioacoustic data on topotypes of B. pseudopseudis, and re-evaluate the differential diagnosis of the former species with respect to the latter. Head shapes (dorsal and lateral views) presented such variation that should not be used to differentially diagnose them as originally proposed. On the other hand, the presence of a dermal ridge along outer tarsi, and color patterns of the eyes and dorsal surface of hand/toe disks still represent diagnostic characters between both species. We also found differences in temporal (call duration; notes per call), spectral (dominant frequency; harmonics), and structural (pulsed/non-pulsed note structure) traits of their calls. Distribution of B. sapiranga is extended eastward (Paracatu), which corresponds to the first record for the State of Minas Gerais, whereas B. pseudopseudis distribution seems to be restricted to rocky montane field environments of northern Goiás State.

An emerging frontier in ecology explores how organisms integrate social information into movement behavior and the extent to which information exchange occurs across species boundaries. Most migratory landbirds are thought to undertake nocturnal migratory flights independently, guided by endogenous programs and individual experience. Little research has addressed the potential for social information exchange aloft during nocturnal migration, but social influences that aid navigation, orientation, or survival could be valuable during high-risk migration periods.

Anecdotally, horses' gaits sound rhythmic. Are they really? In this study, we quantified the motor rhythmicity of horses across three different gaits (walk, trot, and canter). For the first time, we adopted quantitative tools from bioacoustics and music cognition to quantify locomotor rhythmicity.

Acoustic communities are acoustically active species aggregations within a habitat, where vocal interactions between species can interfere their communication. The acoustic adaptation hypothesis (AAH) explains how the habitat favors the transmission of acoustic signals. To understand how bird acoustic communities are structured, we tested the effect of habitat structure on the phylogenetic structure, and on the phylogenetic and vocal diversity of acoustic communities in a semi-arid zone of Mexico.

It is essential to discover and identify animals in species level in the wild to achieve the collection of baseline data and benefit better understanding and conservation of the rare species. However, this is far from being realized for many beaked whales in the deep sea, including the Deraniyagala's beaked whale (), which is one of the least-known whales with no confirmed live sightings at sea yet all over the world. Here, we provide the first robust field identification of , by integrating DNA sequencing of skin biopsies, acoustic data, and photographs.
