New online! Bending back the curve of shark and ray biodiversity loss
Bending back the biodiversity loss curve of sharks and rays. The loss of sharks and rays to date has involved serial depletion of the largest, most evolutionary and functionally distinct species, and the increasing prevalence of smaller-bodied species that have benefited from release from predation.
New paper out today in @natrevbiodiv.nature.com by the #GlobalSharkTrends team: Bending back the curve of shark & ray biodiversity loss;

Successfully wrapped up our third and final week measuring rays in Europe at the Natural History Museum in London 🇬🇧 huge thank you to @nhm-london.bsky.social for hosting, and thank you @amandasodysseys.bsky.social and @nickdulvy.bsky.social for helping me measure 309 rays representing 123 species!
Three researchers in white lab coats stand smiling in a specimen room, holding a Mobula thurstoni specimen. Behind them are shelves lined with tall glass jars containing preserved fish.

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 🇬🇧!

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

Always glad to celebrate my sisters in STEM! Happy International Day of Women & Girls in Science 👩🔬🦈- Grateful for the incredible women who have supported me and for all the amazing women scientists blazing trails and making a difference every day. #WomenInScience #WomenInSTEM @rachhson.bsky.social
Dive into the exciting work of the Earth to Ocean Research Group! Follow our brilliant students, research assistants, lab managers, postdocs, and faculty as they explore, discover, and make waves in science. 🌊✨

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

Was my great pleasure to spend two weeks here at the South African Institute for Aquatic Biodiversity measuring #metabolic #morpholgy traits of rays w/ @earth2ocean.bsky.social @sfuscience.bsky.social grads. Here is
@jaymatsushiba.bsky.social to
give you a sense of the size of the collection...
My research uses publicly available data to assess how well marine protected areas cover shark and ray species ranges. I focus on identifying gaps in protection & prioritizing areas to protect species most at risk of extinction.
Let’s connect on sharks, spatial conservation, and the future of MPAs!✨
🌊👋 Hi Everyone! thought I would take a second to introduce myself! I'm Amanda Arnold, a PhD student with @nickdulvy.bsky.social in the @earth2ocean.bsky.social research group at Simon Fraser University in Vancouver, Canada.
I've made a starter pack of scientists who study sharks and rays, and environmental advocates who work to protect them.
Follow these fine folks, and let me know if I missed anyone! 🧪🦑🌎

Phew! after 2 weeks working @NRF_SAIAB its a wrap. We measured 25+ #MetabolicMorphology traits from 43 sharks & 240 ray specimens, spanning 60 species, from endemic catsharks, skates & electric rays to pelagic and deepsea sharks
Thanks to @SFUResearch & @NSERC_CRSNG 🧪🦈🌎
@vanderwright.bsky.social @rachhson.bsky.social good thing we don’t go outside cause apparently we’re terrible at spotting sharks
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! 🌊🦈
Happy #International_Womens_Day to these amazing scientists who provide me with *constant* support in the lab @rachhson.bsky.social @hannahvwatkins.bsky.social

New analysis on #SharksintheDark funded by @SharkRayFund shows one in seven deepwater sharks and rays are threatened with extinction, more than twice the number reported a decade ago. 🦑🌍🐟

A global fishing prohibition below 800 m would provide 30% vertical refuge for 30% of threatened deepwater sharks and rays. 🦑🌍🐟

Rachel and Amanda Arnold thrilled to find super cute SF mako shark
Its just like unwrapping a birthday pressie, opening tank of preserved shark and ray specimens at California Academy of Sciences
Super excited to welcome new PhD student Rachel Aitchison to the Earth to Ocean Research group at Simon Fraser University. She's working on "Metabolic morphology of rays"
