New paper 🐟🦑🦞🪼🐋 encouraging greater operationalisation of ecosystem- based #fisheries management and ways to account for trophic interactions. With @laurablamey.bsky.social and @csiro.bsky.social colleagues working on #EBFM #MICE link: doi.org/10.1111/faf.... thread 1/3..

Towards Implementing Multispecies Harvest Strategies That Are Robust to Interacting Populations

Another idyllic day on Brisbane/Meanjin’s north Stradbroke Island (Minjerribah) watching dolphin pods and humpback whales as they start their long journey towards Antarctic feeding grounds #WhaleWatching #BottlenoseDolphin

Blue Pacific Ocean with 2 humpback whales showing their dark blue backs and small dorsal fins above the water, most likely a mother and her calf moving close inshore in a southerly direction

Blue- green ocean water close to shore where a pod of grey bottlenose dolphins were feeding and playing. My photo shows an adult with a small calf towards centre of pic, with their large dorsal fins showing and to the right is a tip of a dolphin snout peeping above the water

Florida's 1,100 natural springs face threats from reduced flow, habitat loss, and excessive algae. Many popular springs are impaired by pollution, despite $357 million spent on restoration since 2011. A geographer explains how to restore them:

Florida’s springs are a window into the state’s groundwater system. Revitalizing them will require multiple solutions tailored to each spring.

I agree as there’s been ongoing uncertainty whether oysters are carbon positive or negative but if I understand this study it indicates an overall net benefit. My colleagues note they measured marine CO2 removal, which isn’t 1-1 with atmospheric CO2 removal, so there’s hope but still uncertainty

An excellent thought-provoking read about what we as humans should be contemplating before we resist or resign ourselves to the GenAI revolution. Just one of several great quotes:

“Promote and produce original work of value, work that’s cliché-resistant and unreplicable, work that tries”

YES! THIS on GenAI!

Please read this absolutely splendid piece of writing that had me cheering, a little bit weepy, and writing in the margins:

"An extraordinary amount of money is spent by the AI industry to ensure that acquiescence is the only plausible response. But marketing is not destiny."

What if you were immune to all viruses? 🦠🧪

A small number of people carry a rare genetic mutation that causes their bodies to produce interferons, virus-blocking proteins, all the time, keeping them immune without activating the rest of the immune system.

Just the good news we need - a nature-based solution for climate change mitigation that could be scaled up to help with carbon sequestration plus is a tasty food source - at least for those of us that like oysters #ClimateChange #CO2reduction #OysterFarming

Proceedings of the National Academy of Sciences @pnas.org · 15d

A delicious win-win: Oyster farming helps sequester carbon, not just because the bivalves lock CO2 in their shells but even more so because the oysters promote primary production and organic carbon sedimentation in the sea around them. In PNAS: www.pnas.org/doi/10.1073/...

Another critique showing that the Sala et al. 2021 estimate of carbon release by bottom trawling is ridiculous.

It estimates an increase in NW European shelf OC mineralization of 0.27 Mt C yr−1, which is an order of magnitude smaller the previous estimates.

Singing with gusto, I had a laugh photographing this New Holland honeyeater! #BirdWatching #wildoz #Nectarivore #SunshineCoastHinterland

A bird perched on a pale diagonal stem with green background from a bush.. honeyeater bird has black and white streaks on chest, yellow on wing and top of tail, white eye with black head and open bill with long tongue showing during his very loud tweeting and singing! I snapped this photo with my canon as he opened his bill.

🚨Arctic sea ice has shrunk by about 50% since 1978 🚨

This is reshaping ecosystems, accelerating global warming and threatening communities that rely on it.

A polar scientist shares what he’s seen on the ice and what’s at stake:

A walk across Alaska’s Arctic sea ice brings to life the losses that appear in climate data

A polar scientist explains the changes hunters who rely on the ice are seeing off Utqiagvik, and how those shifts are echoed in satellite data and climate models.
