Uppsala University was curious to see for themselves the new order of #sponges we discovered 😅

The use of historical #collections is pivotal in the understanding of today's taxonomy and biodiversity.

Our SponBIODIV partner @uu.se illustrates this with a 19th century🎩 #sponge🪸 collection from the North Atlantic 🌊.

Scientists urge caution, further assessment of ecological impacts above deep-sea mining • MBARI A new study argues that deep-sea mining poses significant risks not only to seafloor ecosystems, but also to animals in the vast midwater realm.

Their findings, published in @natureportfolio.nature.com, reaffirm earlier work by researchers including Steven Haddock of @mbarinews.bsky.social, who have urged the global community to move cautiously in the face of all the uncertainties. mbayaq.co/44cVKEa

Life Finds a Way, Even on Inactive Hydrothermal Vents - bioGraphic In the darkness of the deep sea, animals flourish on hydrothermal vents that have gone cold.

Scientists long assumed that inactive vents, without the mineral-rich plumes that make active vents so mesmerizing, didn’t host unique lifeforms.

“It turns out that we just weren’t looking very closely,” says marine biologist Jason Sylvan.

El MNCN presenta su propuesta de actividades para la Semana de la Ciencia | Museo Nacional de Ciencias Naturales Habrá un homenaje a Jane Goodall en el que Rebeca Atencia, considerada su sucesora, hablará de su experiencia con la primatóloga

Del 4 al 16 de noviembre se celebra la semana de la ciencia (si, son dos semanas aunque por el nombre parezca una)

Tienes toda la información en el enlace pero yo te recomiendo especialmente el homenaje a Jane Goodall que tendremos el jueves 12

New Zealand oceans warming 34% faster than global average, putting homes and industry at risk, report finds NZ$180bn worth of housing and $26bn of infrastructure at risk of flooding and storm damage, new government report finds

“New Zealand is bearing the brunt of these warming seas because of its position…Meanwhile, the Subtropical Front — the boundary between cold subantarctic water and warmer subtropical water…has moved 120km west…the first time a shift in large-scale ocean circulation around NZ had been observed”🧪

I signed on to this letter of support to reconsider....its essential to research and science in #Antarctica. 🧪🇦🇶

🌍 Antarctica’s krill crisis is exploding.
🦐 518,000+ tons harvested — risking whales, penguins & the fragile Southern Ocean ecosystem.
🔥 Climate change + unregulated fishing = ecological tipping point.
