Frontiers in Ecology and Evolution, 2022 Acoustic communication serves a crucial role in the social interactions of vocal animals. Duetting—the coordinated singing among pairs of animals—has evolved independently multiple times across diverse taxonomic groups including insects, frogs, birds ...

Vocal amplitude corresponds to emergence counts in urban bat bridge roosts
Wildlife Society Bulletin, EarlyView.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 ...

Sympatric song variant in mountain chickadees Poecile gambeli does not reduce aggression from black-capped chickadees Poecile atricapillus [PDF]
, 2016 When habitats overlap and species compete for resources, negative interactions frequently occur. Character displacement in the form of behavioural, social or morphological divergences between closely related species can act to reduce negative ...

The ultrasonic nonlinearity parameter for biological media
Archives of Acoustics, 2015 The nonlinearity parameter B/A of several soft tissues was measured using two independent methods. The B/A values of most soft tissues were found to be between 7 and 8, with the exception of fat which has a B/A value close to 11.

Vocal usage learning and vocal comprehension learning in harbor seals
BMC NeuroscienceBackground Which mammals show vocal learning abilities, e.g., can learn new sounds, or learn to use sounds in new contexts? Vocal usage and comprehension learning are submodules of vocal learning.

Deep Machine Learning Techniques for the Detection and Classification of Sperm Whale Bioacoustics
Scientific Reports, 2019 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 ...

Functional Ecology, EarlyView.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 ...

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]
, 2011 Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

Methods in Ecology and Evolution, EarlyView.Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are
