Cool to be a small part of this project led by @mjw-marine.bsky.social on non-lethal tools for accurate sex identification in European eels.

Check out the paper below!

Our new paper in @globalchangebio.bsky.social: artificial light at night creates an ecological trap for wild reef fish. Settlement ↑ under artificial light (up to 8× higher), but survival ~50% lower due to predation, disrupted settlement timing, and altered metabolic rhythms: doi.org/10.1111/gcb....

Sorry to hear Bob. Hope you’re doing ok.

Are Behavioral Ecotoxicity Endpoints Relevant at the Population Level? Evidence-Based Insights for Environmental Protection A substantial body of evidence exists demonstrating that exposure to environmental contaminants can alter animal behavior. Moreover, methodological and technological advancements, as well as increasin...

New paper led by @michaelgbertram.bsky.social!

Environmental pollutants can alter animal behaviour, but behaviour is rarely used in risk assessments. We outline how behaviour is key for population outcomes, and why it should be taken seriously in chemical regulation.

It’s great to see our systematic map highted by @envevidence.bsky.social as the most read article of 2025! It was a huge amount of work, so I am glad people are seeing it. We highlighted some major gaps and issues within the field, as well as practical ways to move forward

Congrats @rhieastment.bsky.social!

Please help us classify all fish species by their social systems 🙏! Any and all observations or general knowledge are useful. Log them at shoalbase.org, the form takes about a minute to fill in 😀.

ABL:AOC 2025 Session 5 Talk 2 / Jack Brand Pharmaceutical pollution alters river-to-sea migration success in Atlantic salmon (Salmo salar)

It was great to present the results of our research on how pharmaceutical pollutants can affect salmon migration at the recent @animalbehaviour.live conference!

Such an amazing long term project!

Temporal Increases in Mercury Concentrations are Associated with Increased Risk of Death by Infectious Disease in Harbour Porpoises (Phocoena Phocoena) Trace elements, particularly heavy metals like mercury, pose significant risks to marine ecosystems due to their toxic and bioaccumulative properties. Concentrations in some marine species show concer...

📣New paper out today!

We’ve found concentrations of mercury in UK-harbour porpoises is increasing. 📈🐬

We also found concentrations of mercury were associated with an increased risk of dying from infectious disease.☠️

Loggers attached to birds can affect foraging behaviour Loggers have become a central part of research on seabirds and other groups of animals over the past 20 years. In seabird research, loggers provide very useful documentation of diving behaviour…

#biologging #research is booming - but do #loggers actually impact the birds? Yes, they do - depending on the mass and attachment location. If you work with biologging, you should read our latest publication seapop.no/en/2025/11/l...

My lab at Indiana University is searching for a *postdoc* and *technician* to contribute to our work studying the evolution of social behavior using fruit flies as a model system. Details below, feel free to email me with any questions! More info on our research: saltzlab.com

Effect of hyperoxia (150% air saturation) on warming tolerance in 14 aquatic ectotherms from across the globe. Left: Forest plot showing effect sizes (model estimates ± 95% confidence intervals) for the effect of hyperoxia on warming tolerance. Black symbols are the fast warming (0.3°C min−1) trials, blue symbols are the slow warming (1°C h−1) trials, and yellow symbols are for a net combined effect with random effects for subgroups of the 24 experiments. The effects were considered statistically significant where the 95% confidence interval does not cross the red vertical line. Right: Approximate geographical distributions for the 10 species of fish (top) and four species of decapod crustaceans (bottom) used in the laboratory experiments to assess the effects of hyperoxia on upper thermal tolerance.

Oxygen supersaturation is proposed to buffer against #HeatStress in water-breathing animals. @graham-raby.bsky.social @jutfelt.bsky.social &co re-examine this question in diverse #aquatic #ectotherms, showing that #hyperoxia has minimal impact on thermal tolerance @plosbiology.org 🧪 plos.io/43hzMQa

I am recruting a #postdoc for a project investigating the evolution of avian heat tolerance in @erc.europa.eu project #HotLife. Fieldwork over broad latitudinal gradients, common-garden experiments, and more. Read more and apply👇

Rivers are heating up faster than the air − that’s a problem for aquatic life and people River heat waves are rising faster than the pace of air heat waves. That’s a problem for fish, drinking water quality, and food and energy production.
