A bit late, but we’ve (@rachhson.bsky.social @nickdulvy.bsky.social) wrapped up our second week measuring rays across Europe. Goodbye Paris and thank you to the teams at @mnhn.fr who made it possible! 🇫🇷✨on to London 🇬🇧! @earth2ocean.bsky.social #labwork #mobulamonday #scienceinaction #womeninstem

The E2O team making waves (and measuring fins) in Hamburg! Great to see @sfubiosciences.bsky.social in action! @sfuscience.bsky.social

Just wrapped up a great week measuring rays at the Museum der Natur Zoologie @leibnizlib.bsky.social in Hamburg 🇩🇪 for @rachhson.bsky.social’s PhD, over 135 specimens measured! 🦈✨ Next stop: Paris 🇫🇷, as our whirlwind tour through Europe’s ray collections continues @nickdulvy.bsky.social

Great to be back in BC's Okanagan Valley! Saw this out the front door of a house that our BC Biodiversity Team will be staying in next week.

The @nserc-resnet.bsky.social AGM is in full swing, and last night the "Palen Lab and friends" team crushed it at trivia! #Zhouvenzz photocred: @elsongalang.bsky.social

Are you a student presenting research on invasive species at the annual AFS meeting this year? If so, please see the flyer below for a travel award opportunity 🐟! @amfisheriessoc.bsky.social @sdsufishecology.bsky.social

Yesterday I presented my ongoing thesis research at the IDEAS 2025 conference. The project has come a long way and I was excited to share my progress so far! @sfuscience.bsky.social @earth2ocean.bsky.social @nserc-resnet.bsky.social

Our PhD candidate, Britt Milner, recently had her Master's research published in the Canadian Journal of Fisheries and Aquatic Sciences! Check out the full article here: doi.org/10.1139/cjfa... #AquaticScience #salmon #WomenInScience

New research from E2O's Dulvy Lab was published in Science yesterday. Check out the thread below! #GlobalSharkTrends #MarineScience #SharksAndRays

Nick Dulvy@nickdulvy.bsky.social · 2y ago

New #GlobalSharkTrends study published in @science.org reveals #overfishing has more than halved shark & ray populations over the past 50-years causing widespread erosion of ecological function and exceptionally high extinction risk 👉Full article bit.ly/GlobalSharkTrends 🧵1/20

📢Re-introducing E2O! We’re Earth to Ocean Research Group @SFU, dedicated to ecology and conservation. Led by Drs. Reynolds, Moore, Côté, Palen, and Dulvy (L-R), our interdisciplinary and quantitative approach aims to generate meaningful insights for conservation and management. 🔗: earthtooceansfu.ca

Congratulations to Beth Oishi from the Côté Lab (@redlipblenny.bsky.social) on successfully defending her MSc thesis yesterday!

The Palen Lab is looking for a GIS Analyst! See job posting below and share with interested individuals. #geospatial #ecology #conservation #RenewableEnergy

New op-ed from @wpalen.bsky.social and the Liber Ero fellows. "The new amendments to the IAA point clearly toward a regional approach by directing federal agencies to consider 'the cumulative effects of physical activities'”. Read more: policyoptions.irpp.org/magazines/ju...

Environmental-impact reviews should take a more regional perspective

Resource projects and other industrial developments are generally evaluated in isolation, which ignores harms between landscapes and watersheds.

Yesterday at #NACCB2024 Ira Sutherland (@socialeco.bsky.social) presented the Palen Lab's work on strategic planning of renewable energy to limit cumulative impacts on the BC landscape.

This week is the North American Congress for Conservation Biology! The Palen Lab is volunteering and will also be giving a talk about their work on cumulative impacts of renewable energy.

Loving the vibes here at SFU today View over the reflecting pool in the academic quadrangle at Simon Fraser University, Burnaby campus on the unceded territory of the Coast Salish Peoples including the Squamish, Musqueam, Tsleil- Waututh, and Kwikwetlem nations

What a great weekend for E2O! The Palen & Côté labs made waves at #PEEC2024 at the Bamfield Marine Sciences Centre. Meanwhile, the Dulvy lab shared insights at #NEPSSVI at the Seattle Aquarium. From local invasive species to global protected areas, we are passionate about sharing our science! 🌊🦈

Thank you to the Invasive Species Council of BC for inviting me to share some green crab work at #invasives2024! #bcinvasives

Scientific American article by @whysharksmatter.bsky.social quotes @sharkadvocates.bsky.social “It’s been at least 15 years since scientists sounded alarm bells over the serious depletion of deepwater dogfish and gulper sharks off Europe” www.scientificamerican.com/article/deep...

One in seven species (14%) of deepwater sharks and rays is threatened with extinction - and overfishing is the main reason theconversation.com/fished-for-t...

Fished for their meat and liver oil, many remarkable deep-water sharks and rays now face extinction

Long lifespans and slow reproduction rates make deep-water sharks and rays as vulnerable to overexploitation as whales once were. We must place them under protection to avoid extinctions.
