I will forever be haunted by this footage.
Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.
What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.

Accelerated Arctic warming is reshaping the polar environment, but focusing only on the impacts of long-term annual temperature rise can miss key consequences of shorter-lived, but extreme, weather shifts coming as a result of climate change.
Winter warming and rain extreme events pose overlooked threat to Arctic life
It’s well established that the slow incremental “press” of rising temperatures is changing the Arctic landscape, threatening the survival of plants and animals adapted to this unique ecosystem. Less…

Such a nice way to finish our first day! 😁
The workshop team presented themselves in the evening session: Dreams, Fantasy Dreams... and Genomics 💭🧬 We then continued with more activities for the participants to mingle and network! 🙆🏻♀️ #evomics2025 #genomics #bioinformatics

Guess what happened today? A government agent got in touch with me after reading my paper! See my work make a real difference in protecting species is what I've been aiming for as a conservationist. It might be just a simple e-mail, but it pumped me up to keep working hard!😊

Our new contribution to the conservation of biodiversity of sharks and rays is out to the world! ⚠️🧬🦈
🧬🦈🌊 New study reveals the urgency of regulating the trade of sharks and rays in Brazil. A Meta-Analysis of all studies using DNA based methods to track trade of elasmobranchs identified 64 species being commercialized, being 83% threatened ones (IUCN). Check the key highlights:
