Green staghorn coral may be more likely to survive ocean warming if crabs are around https://phys.org/news/2025-02-green-staghorn-coral-survive-ocean.html

"predation by #starfish led to wounds that bled mucus, which in turn attracted the hoof-clawed #crab... the #crabs fed on the mucus but did not harm the coral... they also fed on nearby #seaweed, typically the vectors for infectious #bacteria, which led to infection prevention in the #corals... coral that were protected by the crabs were 60% less likely to suffer tissue loss"

Tide’s out, dinner’s up: why Wales is at the forefront of a #seaweed revolution - https://www.theguardian.com/travel/2024/nov/10/wales-seaweed-revolution-coastal-foraging-trip-pembrokeshire "Food, fertiliser, fuel … seaweed has been a life force for centuries. On a coastal foraging trip in Pembrokeshire, we discover it’s now behind a new green initiative, too"

Do Not Pin Your Hopes for Guilt-Free Hamburgers on Seaweed

"I did the math, and it doesn’t add up.
#Seaweed doesn’t just fail to reduce emissions as well as promised. It sucks the air out of productive debate. Hoping for any simple solution to hack complex food system problems distracts us from both the complexity and the magnitude of the changes necessary. Red algae, in other words, is a red herring."

Integrated physiological response by four species of #Rhodophyta to submarine groundwater discharge reveals complex patterns among closely-related species https://www.nature.com/articles/s41598-024-74555-6

"successful species of #algae can quickly change the concentration of dissolved substances inside their cells to match external changes. This ability to regulate internal water pressure is crucial for survival"

Fishers & scientists unite to restore #seaweed populations on Chilean coast https://news.mongabay.com/2024/10/fishers-scientists-unite-to-restore-seaweed-populations-on-chilean-coast/

"The disappearance of the seaweed has formed ocean deserts. Its absence has not only reduced #biodiversity but also deprived the area of the ecosystem services that they provide. Despite considerable challenges, the project already shows signs of hope... At the last observation, after two months of crop repopulation, there were more than 2,000 repopulated seedlings between the two species."

Black kelp fly (Coelopa frigida). There were uncountable numbers of these so I find it surprising that there are fewer than 300 observations (in North America) on iNaturalist. People just don't care about flies like they should.

🌊🍙MOTHER OF THE SEA🍘✨

Kathleen Mary Drew-Baker (キャスリーンメアリードリューベイカー 1901-57) is not well known in her homeland, but in Japan she has become a national hero, remembered at Sumiyoshi-jinja in Uto (宇土-Kumamoto Prefecture) as the savior of the seaweed industry.

On April 14th Japan's nori farmers travel to pay their respects to Drew-Baker's memorial overlooking the Ariake Sea, a huge bay filled with seaweed farms.

Going deeper for healthy offshore reefs in Storm Bay https://phys.org/news/2024-07-deeper-healthy-offshore-reefs-storm.html

#Scientists have used high-tech underwater #robots to take a closer look at the deep offshore reefs on the east coast of Bruny Island in #Tasmania and have revealed the seabed #biodiversity there for the first time... #seaweed cover dominates the shallower depths of these reefs, and #sponges, #corals, and other seabed #animals are more prevalent below 40 meters.

Here's my final Harbour Walls print. Yes I gave it a name. I think this is a pretty accurate representation of the colours.

There are 24 in the edition and it will be available in my shop later today.

It's easily my most ambitious print to date, in fact my next few will be half the number of layers. My son kept telling me that 12 layers was too many and I should reduce them.

The world’s fourth mass #CoralBleaching is underway, but well-connected #reefs may have a better chance to recover https://theconversation.com/the-worlds-fourth-mass-coral-bleaching-is-underway-but-well-connected-reefs-may-have-a-better-chance-to-recover-230755

"#Corals remain healthier and recover faster if they are surrounded by #fish that eat different types of #seaweed, such as #parrotfish, #surgeonfish and #rabbitfish. #SeaCucumbers also are important reef partners. They feed on #bacteria and other organic materials in ocean sediments, cleaning up the area around #CoralReefs."

Happy birthday to #botanist Isabella Aiona Abbott (1919-2010), renown algae expert, celebrated seaweed cook, devoted teacher and mentor, expert on Hawaiian ethnobotany, the first Indigenous Hawaiian woman to earn a doctorate in science and the first woman or person of colour to become a full professor on Stanford's biology faculty. 🧵1/n

Secrets of #sargassum: Scientists advance knowledge of #seaweed causing chaos in the Caribbean and West Africa
https://phys.org/news/2024-05-secrets-sargassum-scientists-advance-knowledge.html paper: https://www.pnas.org/doi/10.1073/pnas.2312173121

"floating mats of sargassum have long been present in the North #Atlantic. However, since 2011, a population has established between West Africa and South America, and increased in size to form 'the great Atlantic sargassum belt'—a 9,000km-long bloom, visible from space and estimated to weigh 35 million tons."
