WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring. [PDF]

Ecology
Abstract Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers.

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs. [PDF]

Integr Zool
Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but

Shaped by Fire: Unravelling the Impact of Fire on Lizard Gut Microbiome. [PDF]

Mol Ecol
ABSTRACT In recent decades, wildfire regimes have changed significantly, with increases in frequency, severity and area affected, leading to major habitat alterations that may impact species ecology. While fire's role in plant ecology is well studied, its effects on animal biotic interactions remain poorly understood.

Influence of conspecifics and road noise on the properties of the advertisement call of Phyllodytes luteolus (Anura, Hylidae). [PDF]

Ecol Evol
In this work, we investigated the influence of motor vehicle noise on a highway in the municipality of Ilhéus on the acoustic parameters of the advertisement call of a species of anuran with bromeligenous habits. This was the first study to investigate this effect on a species that spends its entire life in bromeliads and to present data/values of its ...

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights. [PDF]

Anat Rec (Hoboken)
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

Two new syntopic species of glassfrogs (Amphibia, Centrolenidae, Centrolene) from the southwestern Andes of Ecuador [PDF]

PeerJ, 2023
We describe two new species of glassfrogs of the genus Centrolene living in syntopy at La Enramada, province of Azuay, southwestern Ecuador. They were found in a small creek in montane evergreen forests at 2,900 m elevation.

Does Participatory Bird Monitoring Provide Accurate Data for Ecological Research? An Experience in Rural Southwestern Mexico. [PDF]

Ecol Evol
Trained local people are capable to conduct bird monitoring and generates useful data for testing ecological hypotheses related to anthropogenic impact. Scientific endeavors based on community projects should develop training strategies aimed at enhancing monitors' skills in both bird identification and abundance recording.
