Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

open access: yesIbis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

AquaVib: Enabling the Separate Evaluation of Effects Induced by Acoustic Pressure and Particle Motion on Aquatic Organisms

open access: yesJournal of Marine Science and Engineering
Scientific awareness is rising regarding fish and sea invertebrates’ sensitivity to the sound field’s particle motion component. The AquaVib, a distinctive laboratory setup, provides a practical methodology for controlled sound exposure experiments on ...

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

open access: yesIbis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Automated bioacoustic identification of species [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2004
Research into the automated identification of animals by bioacoustics is becoming more widespread mainly due to difficulties in carrying out manual surveys. This paper describes automated recognition of insects (Orthoptera) using time domain signal coding and artificial neural networks.

Unraveling Biotypes Related to Thermotolerance During Lactation in Maternal‐Line Pigs Through Principal Component and Factor Analyses

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Heat stress imposes significant challenges to welfare, health, and productivity of lactating sows due to their limited thermoregulatory capacity and increased metabolic heat load. Genetic selection for improved heat tolerance is a promising yet complex approach, given the large number of biological processes involved in heat stress response ...

Management of acoustic metadata for bioacoustics

open access: yesEcological Informatics, 2016
AbstractRecent expansion in the capabilities of passive acoustic monitoring of sound-producing animals is providing expansive data sets in many locations. These long-term data sets will allow the investigation of questions related to the ecology of sound-producing animals on time scales ranging from diel and seasonal to inter-annual and decadal ...

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Interview-based sighting history to investigate the historical range and dynamics of dugongs in China

open access: yesRoyal Society Open Science
The dugong (Dugong dugon) is the first marine megafauna to be declared functionally extinct in China, yet its historical range and extinction dynamics remain poorly understood.

Social context shapes acoustic signalling in the territorial damselfish Stegastes fuscus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Acoustic communication plays an important role in social interactions in reef fishes, but how signals vary with behavioural context remains poorly understood for many species. We characterised the acoustic repertoire of the Brazilian damselfish Stegastes fuscus using synchronised underwater audio–video recordings and tested how sound features ...
