Animal vocalizations encode rich biological information, making bioacoustic analysis a valuable non‐invasive tool for assessing animal welfare and population dynamics. However, traditional methods relying on manual feature selection are labour‐intensive, subjective and lack scalability for the large datasets generated by passive acoustic monitoring ...

Passive acoustic monitoring (PAM) allows for the study of vocal animals on temporal and spatial scales difficult to achieve using only human observers. Recent improvements in recording technology, data storage, and battery capacity have led to increased ...

Deep Machine Learning Techniques for the Detection and Classification of Sperm Whale Bioacoustics
We implemented Machine Learning (ML) techniques to advance the study of sperm whale (Physeter macrocephalus) bioacoustics. This entailed employing Convolutional Neural Networks (CNNs) to construct an echolocation click detector designed to classify ...

Birds are commonly used as indicators of the effect of habitat degradation on biodiversity in the tropics. However, monitoring birds and their habitat in a way that is consistent, reliable and scalable remains an important challenge. Here, we examine whether bioacoustics and remote sensing can be used to efficiently monitor avian biodiversity and ...

Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

The role of freshwater bioacoustics in ecological research
Conventional methodologies used to estimate biodiversity in freshwater ecosystems can be nonselective and invasive, sometimes leading to capture and potential injury of vulnerable species.

Vocal amplitude corresponds to emergence counts in urban bat bridge roosts
In this study, we assessed the relationship between Mexican free‐tailed bat (Tadarida brasiliensis) abundance and the amplitude of their vocalizations at two urban bridges in Tucson, AZ, USA. We found a strong positive relationship between amplitudes of vocalizations and bat abundance, and reciprocal cross‐validation indicated that a model from one ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Many studies have focussed on niche differentiation at the population level to explain the coexistence of similar species. However, information on how individual‐level processes across multidimensional niches shape community dynamics and species coexistence, especially ...

Passive acoustic monitoring (PAM) is an effective remote sensing approach for sampling acoustically active animal species and is particularly useful for elusive, visually cryptic species inhabiting remote or inaccessible habitats.

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
