Rthoptera: Standardised insect bioacoustics in R

Methods in Ecology and Evolution
Almost 100 years after the dawn of insect bioacoustics, freely available and robust analysis tools and protocols are still needed. We introduce Rthoptera, an open‐source R package designed for robust analysis of insect acoustic signals.

Vocal Classification of Vocalizations of a Pair of Asian Small-Clawed Otters to Determine Stress [PDF]

, 2015
Asian Small-Clawed Otters (Aonyx cinerea) are a small, protected but threatened species living in freshwater. They are gregarious and live in monogamous pairs for their lifetimes, communicating via scent and acoustic vocalizations.

Validated Sandwich ELISA for the Quantification of von Willebrand Factor in Rabbit Plasma

Biomarker Insights, 2010
von Willebrand Factor (vWF) is a multimeric plasma protein important for platelet plug formation. As part of its haemostatic role, it is released from endothelial cells during vascular stress or injury and is considered an excellent biomarker of ...

Initial Findings on Visual Acuity Thresholds in an African Elephant (\u3cem\u3eLoxodonta africana\u3c/em\u3e) [PDF]

, 2010
There are only a few published examinations of elephant visual acuity. All involved Asian elephants (Elephas maximus) and found visual acuity to be between 8′ and 11′ of arc for a stimulus near the tip of the trunk, equivalent to a 0.50 cm gap, at a ...

Prototyping an internet-of-things-based bioacoustics system to support research and surveillance of avian-associated infectious diseases

Sensing and Bio-Sensing Research
Zoonotic infectious diseases and cross-species pathogen spillover are driven by biodiversity and spatio-temporal ecological interactions. Generating high-resolution data to approximate the presence and absence of animals and their mobility, density, and ...

Nonlinear phenomena make animal calls alarming for human listeners

iScience
Summary: Animal vocalizations are extremely diverse, and evolutionary approaches to understanding this diversity assume some mapping between their acoustic form and communicative function, with specific features serving universal roles.

Warm temperatures and severe fire drive a range contraction of an avian old-forest specialist in the Sierra Nevada, USA

Frontiers in Bird Science
In recent decades, climate change has exerted detrimental effects on forest ecosystems and the biodiversity they harbor, in part via the combined effects of rising temperatures and changing disturbance regimes. Old-forest species may be acutely sensitive

Bioacoustics and rhythm

Abstract Bioacoustics is an interdisciplinary science; it concerns aspects of communication through sound in animals, including humans. Within language evolution research, bioacoustics is particularly relevant to address questions about the origins and evolution of speech.
