Chemosphere, now STOTEN. 👀😥
STOTEN is now dead. It has been completely removed from Web of Science mjl.clarivate.com/search-results
Warning to environmental scientists! 🧪🦑🌎🐟

The journal STOTEN has been placed on hold by Clarivate, meaning it is under investigation and may lose its indexing (including impact factor). Consider publishing elsewhere.

Excellent article on the oxygen limitation during warming discussions, and our recent paper on the topic.

By @dianasmadeira.bsky.social 🐟🧪
Oxygen limitation is considered a key mechanism of #ThermalTolerance. @dianasmadeira.bsky.social explores how a @plosbiology.org study challenges this idea, showing minimal protective effects of O2 supersaturation in heat-stressed #aquatic #ectotherms 🧪 Paper: plos.io/43hzMQa Primer: plos.io/3XeUtbS

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

Very happy and proud to see this one published! Have a look at this global assessment of the effect – or lack of effect – of extra oxygen (hyperoxia) on ectotherm thermal tolerance! Led by @graham-raby.bsky.social and a team of incredible collaborators working on multiple taxa 🐟 🐠 🦀 🦐.
Oxygen supersaturation has been reported to protect aquatic animals from heat waves. We tested this in a large collaborative experiment on many species of fish and crustaceans. Our new paper in @plosbiology.org shows that the effect of hyperoxia on thermal tolerance is negligible. Unfortunately.

The first project, during 2026, will be a global distributed test of thermal tolerance in the embryos of fishes. We are hoping for many species from various environments and climates.

You can use HusMorph to analyse images of fish — like the above example — or whatever your favourite study organism is 🐟🦐🥬 See our Toolbox paper in Conservation Physiology @conphysjournal.bsky.social for more info: doi.org/10.1093/conp....

Tired of manually landmarking hundreds of images? 📍🖼️😩 Our lab developed HusMorph, a free and open-source tool that automates morphometric landmarking using #MachineLearning — no coding required. Simply train the model on your images, and it quickly places landmarks with human-level accuracy. #AI

Check out our new methods paper for automated length and body shape measurements in animals!
Ever needed to measure the morphological features of your organism across hundreds of images? 🤯 HusMorph uses #MachineLearning to detect morphological landmarks in the image, speeding up your #ImageAnalysis time!

Sad that ChatGPT makes up two male scientists instead of the real scientists Andrea Franke and Catriona Clemmesen.
