3,4‐Methylenedioxymethamphetamine (MDMA) does not induce robust psychomotor activation and 50‐kHz ultrasonic vocalisations in tryptophan hydroxylase 2 (Tph2)‐deficient rats lacking serotonin in the central nervous system

British Journal of Pharmacology, EarlyView.
Background and Purpose 3,4‐Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, is a psychostimulant with entactogenic properties and known to induce arousal and euphoria. As an amphetamine derivate, MDMA acts on the monoamine systems in the brain and stimulates release of dopamine (DA), noradrenaline (NA) and serotonin (5‐HT), yet their ...

Habitat use and diel activity of insectivorous bats across land‐cover types on an Afrotropical oceanic island

Conservation Science and Practice, EarlyView.
Using acoustic surveys, we investigated habitat use and diel activity patterns of insectivorous bats across the main land‐use types of the endemic‐rich Príncipe Island, in Central West Africa. We sampled bat activity at 48 sites spanning old‐growth forests, secondary regrowth forests, shaded cocoa plantations, and horticultural areas.

Whombat: An open‐source audio annotation tool for machine learning assisted bioacoustics

Methods in Ecology and Evolution
Automated analysis of bioacoustic recordings using machine learning (ML) methods has the potential to greatly scale biodiversity monitoring efforts. The use of ML for high‐stakes applications, such as conservation and scientific research, demands a data ...

Species characteristics predict the effectiveness of avian survey methods in an Afromontane sky‐island

Ibis, EarlyView.
Biodiversity conservation requires effective monitoring of ecological communities in remote locations, where limited accessibility often restricts survey efforts. Passive acoustic monitoring (PAM) is becoming an established method for measuring biodiversity, facilitated by the increased accessibility of autonomous recording units.

Using acoustic indices to detect interspecific bird interactions and behaviour

Ibis, EarlyView.
Communication networks and acoustic interactions play a crucial role in shaping animal communities by mediating information exchange between individuals. These interactions contribute to the biophonic component of the soundscape—the acoustic environment of a place—which is increasingly analysed to understand ecosystem structure and functioning. However,

Soundscapes: Species Richness and Community Composition of Neotropical Atlantic Forest Avifauna

Conservation
As tropical forests become increasingly vulnerable to land use changes, fragmentation, and climate shifts, efforts to minimise species loss are essential.

Fight song: variation in singing behaviour and song structure during natural agonistic interactions in a tropical songbird, Adelaide's Warbler (Setophaga adelaidae)

Ibis, EarlyView.
Birds may use their singing behaviours and song structure as agonistic signals in territorial encounters. We conducted an observational study to test this hypothesis in male Adelaide's Warblers Setophaga adelaidae, a tropical songbird that defends a territory year‐round.

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

Royal 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.

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

Journal 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 ...

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

Journal of Zoology, EarlyView.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of
