The role of freshwater bioacoustics in ecological research

open access: yesWIREs Water, Volume 7, Issue 3, May/June 2020., 2020
Fish are the focal study species in the majority of freshwater bioacoustic studies, which often focus on a single species that is recorded in laboratory aquaria. Despite their significant contributions to soundscape composition and ecosystem function, arthropods were poorly represented in the research literature.

Habitat modeling of Irrawaddy dolphins (Orcaella brevirostris) in the Eastern Gulf of Thailand

open access: yesEcology and Evolution, Volume 10, Issue 6, Page 2778-2792, March 2020., 2020
We investigated the habitat of a previously unstudied group of endangered Irrawaddy dolphins (Orcaella brevirostris) in the eastern Gulf of Thailand. Depth and temperature emerged as the most important predictors of dolphin presence and group size. Using our results, we generated a map of dolphin high‐use areas that can be used to inform conservation ...

Conditions leading to exceptionally high temperatures in shallow tropical lakes

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Factors leading to exceptionally high temperatures in shallow tropical waters are examined with high‐resolution measurements and application of a 3‐dimensional hydrodynamic model in an Amazon floodplain lake. Highest near‐surface (0.05 m) temperatures in open water ranged from 31.0 to 37.5°C. Within mats of floating plants maximum temperatures

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Cephalopods play crucial roles in marine ecosystems due to their diverse and indispensable contributions to trophic webs. However, parasitological research on cephalopods remains limited in Aotearoa New Zealand (NZ), despite the commercial significance of certain squid species and the zoonotic potential of the parasites within them. This study aimed to
