The secret acoustic world of leopards: A paired camera trap and bioacoustics survey facilitates the individual identification of leopards via their roars

Remote Sensing in Ecology and Conservation, EarlyView.
Here, we conducted the first large‐scale joint camera trap and bioacoustics survey for large African carnivores in Nyerere National Park, Tanzania. By combining the different data types that each technology produced, this led to the discovery that every leopard has a unique, identifiable roar which enables leopards to be the focus of other, more ...

The voice from the hereafter: vocalisations in three species of Atelopus from the Venezuelan Andes, likely to be extinct [PDF]

Herpetozoa, 2019
Atelopus is a species-rich group of Neotropical bufonids. Present knowledge on bioacoustics in this genus is relatively poor, as vocalisations have been described in only about one fifth of the ca. 100 species known.

An overview of fish bioacoustics and the impacts of anthropogenic sounds on fishes

Journal of Fish Biology, 2019
Fishes use a variety of sensory systems to learn about their environments and to communicate. Of the various senses, hearing plays a particularly important role for fishes in providing information, often from great distances, from all around these ...

A scalable transfer learning workflow for extracting biological and behavioural insights from forest elephant vocalizations

Remote Sensing in Ecology and Conservation, EarlyView.
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 ...

A computer vision approach to classification of birds in flight from video sequences [PDF]

, 2015
Bird populations are an important bio-indicator; so collecting reliable data is useful for ecologists helping conserve and manage fragile ecosystems. However, existing manual monitoring methods are labour-intensive, time-consuming, and error-prone.

Consistent and scalable monitoring of birds and habitats along a coffee production intensity gradient

Remote Sensing in Ecology and Conservation, EarlyView.
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 ...

Interaction of the phencyclidine model of schizophrenia and nicotine on total and categorized ultrasonic vocalizations in rats [PDF]

, 2017
Patients with schizophrenia smoke cigarettes at a higher rate than the general population. We hypothesized that a factor in this comorbidity is sensitivity to the reinforcing and reinforcement- enhancement effects of nicotine.

Rhythm and synchrony in animal movement and communication

, 2018
Animal communication and motoric behavior develop over time. Often, this temporal dimension has communicative relevance and is organized according to structural patterns.

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
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

Translational outcomes in a full gene deletion of ubiquitin protein ligase E3A rat model of Angelman syndrome. [PDF]

, 2020
Angelman syndrome (AS) is a rare neurodevelopmental disorder characterized by developmental delay, impaired communication, motor deficits and ataxia, intellectual disabilities, microcephaly, and seizures. The genetic cause of AS is the loss of expression
