Chameleon #shrimp can adapt camouflage to invasive #algae species https://phys.org/news/2025-01-chameleon-shrimp-camouflage-invasive-algae.html

Adaptation in the Anthropocene: How behavioural choice and colour change enables chameleon #prawns to camouflage on non-native #seaweeds https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.14217

"Depending on the algae they are in, they can turn red, green, brown or transparent... The new results also show that they can camouflage themselves in algae from other oceans with which they did not evolve together."

There was many types of #ClamShells & much #diversity of beautiful & edible #seaweeds washed up on highbanks, post windstorm.
There's over 100 different types of seaweeds found along the coasts of Vancouver Island. There's 6 types of clams found on beaches of the island.

Admiring #seaweeds.

#SeagrassMeadows are rapidly expanding near inhabited islands in #Maldives https://phys.org/news/2024-05-seagrass-meadows-rapidly-inhabited-islands.html

"Currently, nutrient inputs seem to be creating just the right conditions for #seagrasses. But if nutrients continue to increase, there is a risk that the seagrasses will be outcompeted by #seaweeds and smothered... the future of this Maldivian success story may therefore largely lie in our hands."

Seaweeds of the World: A Guide to Every Order

A lavishly illustrated guide to the seaweed families of the world
Seaweeds are astoundingly diverse. They're found along the shallows of beaches and have been recorded living at depths of more than 800 feet; they can be microscopic or grow into giants many meters long.

Check out our new paper “Air-sea carbon dioxide equilibrium: Will it be possible to use seaweeds for carbon removal offsets?” Here, we explain why quantifying air-sea CO2 equilibrium and linking this process to seaweed carbon storage pools is the critical step needed to verify CDR by discrete seaweed beds and nearshore and open ocean aquaculture systems prior to their use in carbon trading.

"With climbing atmospheric CO2, huge amounts of this gas are absorbed by the #oceans, making the waters more and more acidic. This affects a huge number of marine animals and plants alike, but its impact on fleshy #seaweeds around the coast may have knock-on effects across the #FoodWeb, and make our #beaches much less pleasant

The only way to prevent this #acidification of the oceans is to stop releasing so much CO2 into the air, the experts say."

Short walk on Seven Mile Beach this afternoon. Lots of #seaweeds and other sea creatures. Anyone with proper names for these? I know bull kelp and the sea squirts.

#Urchin grazing of kelp gametophytes in #warming oceans: Reina Veenhof et al. https://onlinelibrary.wiley.com/doi/10.1111/jpy.13364

"#Seaweed grazers often get a bad rap for causing devastating loss in #kelp and seaweed habitats. Here, we highlight a positive impact... Small grazers may fulfil an important role in seaweed reproduction, by making sure microscopic gametophytes in the big #ocean can find each other and make babies."

Very excited for this.
