Excellent article on the oxygen limitation during warming discussions, and our recent paper on the topic. By @dianasmadeira.bsky.social 🐟🧪

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.

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

A terrific afternoon for fish biology here at #SEBconference ❤️🐟 Great talks by @leeuwisrobin.bsky.social, Moa Metz, and @erinmcstewart.bsky.social about different ways that fish respond to climate warming!

• Zebrafish can evolve improved growth at warmer temperatures
• Thermal performance curves can undergo a left or right shift
• Ectothermic vertebrates may adapt to global warming by enhancing performance
• Role of selection in shaping thermal resilenceA scientist presents her title slide on a large stage, it features a beautiful picture of a brook trout. A scientist presents the methods of her research on a large screen

🚨Preprint alert!🚨 We found that relevant levels of aquatic oxygen supersaturation do not always offer protective benefits to aquatic ectotherms during acute warming. 🌡️ Big collaborative project with A LOT of CTmax trials!!! ecoevorxiv.org/repository/v...

How do fish evolve to tolerate higher temperatures, and are there trade-offs? We explore these questions in our new paper @natclimate.nature.com led by Anna Andreassen @annahandreassen.bsky.social www.nature.com/articles/s41... 🧪🐟🦑

A horizon scan of biological conservation issues for 2025
We discuss the outcomes of our 16th horizon scan of issues that are novel or represent a considerable step-change and have the potential to substantially affect conservation of biological diversity in the coming decade. From an initial 96 topics, our international panel of 32 scientists and practitioners prioritised 15 issues. Technological advances are prominent, including metal and non-metal organic frameworks, deriving rare earth elements from macroalgae, synthetic gene drives in plants, and low-emission cement. We include new insights into accelerated impacts of changes to Antarctic ice masses and air and water quality. We hope that anticipating and mitigating negative impacts, and making best use of new opportunities related to these issues, will contribute to better outcomes for biological diversity.

Hi Bluesky community! 👋 I'm Robin and new here. I'm a scientist who studies mostly fish, and based on scholargoggler.com I'm especially a fan of sablefish 🐟 But these days I also do a lot of research with zebrafish! 🦓 I'm fascinated with how the environment shapes their physiology and evolution.
