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

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 7, Page 1539-1556, April 2026.
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 ...

Entomogenic Climate Change [PDF]

open access: yes, 2008
Rapidly expanding insect populations, deforestation, and global climate change threaten to destabilize key planetary carbon pools, especially the Earth's forests which link the micro-ecology of insect infestation to climate.

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

open access: yesIbis, Volume 168, Issue 2, Page 520-540, April 2026.
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

open access: yesIbis, Volume 168, Issue 2, Page 541-553, April 2026.
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

open access: yesConservation
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)

open access: yesIbis, Volume 168, Issue 2, Page 766-778, April 2026.
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

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.

Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Complex taxonomy and global phylogeography of the well-known tropical earthworm Pontoscolex corethrurus [PDF]

open access: yes, 2018
Few earthworm species are peregrine and among them, Pontoscolex corethrurus is the most well-known. Probably native from the Guyana shield, this earthworm is nowadays distributed worldwide, in the tropical and sub-tropical zones.
