Happy birthday to #botanist Isabella Aiona Abbott (1919-2010), renown algae expert, celebrated seaweed cook, devoted teacher & mentor, expert on Hawaiian ethnobotany, 1st Indigenous Hawaiian woman to earn a doctorate in science & the 1st woman or person of colour to become a full professor on Stanford’s biology faculty. She literally wrote the textbook on Californian seaweed & 🧵

Linocut portrait of Isabella Aiona Abbott in indigo on cream coloured paper. She’s facing forward at a table in a shirt and sweater vest with a sheet with algae samples on the table. In my print, she is surrounded by algae of the Pacific, all of which appeared in Abbott's research publications, including several species she discovered, or based on images of specimen she personally collected or whose traditional use as food she documented. The algae are in pinks, khaki green and rust.

"How Freshwater Lake Algae Blooms are Worsened by Climate Change and Wildfire Smoke Dry Deposition"

"Visiting your local lake? There is probably much more algae on the lake this year than normal. This is why..."

Climate change kills.

‘Like an underwater bushfire’: SA’s marine algal bloom is still killing almost everything in its path

> The algal bloom in SA is a warning to coastal communities, as well as tourism, seafood and aquaculture industries. It’s a sign of what’s to come as the oceans warm.

certain parmelitic lichens, the usnea, develop a unique elasticity that allows them to resist the wind - as seen here on the summit ridge of Cap Sizun - and to grow cute tiny beards • certains lichens parmélies, les usnées, développent une élasticité singulière leur permettant de resister au vent - comme ici sur la crète sommitale du cap sizun - et se traduisant par des mini-barbes toutes cute. #lichen #fungi #algae #capsizun

Uncovering a unique light-harvesting structure in marine #algae
Photosystem II–FCPII complex found in a marine alga could shape the future of artificial #photosynthesis

high-resolution analysis of a photosynthetic complex found in , Chrysotila roscoffensis. This marine alga belongs to the #coccolithophore species known for producing calcium carbonate plates and fixing carbon at the ocean surface.

EurekAlert!Uncovering a unique light-harvesting structure in marine algaeHaptophytes—the unicellular photosynthetic marine algae—are one of the major contributors to marine biomass. Scientists at Okayama University, Japan, unveil the first high-resolution structure of the photosystem II–FCPII (photosynthetic supercomplex) in a marine haptophyte, Chrysotila roscoffensis. This discovery sheds light on the unique approach of sunlight capture and energy management by the complex, offering new insights into marine biology and potential advances in artificial photosynthesis technology.

New study reveals how competition between #algae is transforming the gulf of Maine
As the ocean warms across its temperate regions, #kelp forests are collapsing and turf algae species are taking over. This shift from dense canopies of tall kelp to low-lying mats of turf algae is driving biodiversity loss and altering the flow of energy and nutrients through reef #ecosystems.

EurekAlert!New study reveals how competition between algae is transforming the gulf of MaineNew research, led by Bigelow Laboratory scientists, shows how rapidly proliferating turf algae are waging “chemical warfare” to inhibit the recovery of kelp forests along Maine's warming coast.

Discovery suggests that #RedAlgae use colors for inter-species communication phys.org/news/2025-05-discover

"a certain kind of cells of red #algae contain bodies of tightly packed microspheres of a light-reflecting material. In the growth tips of the alga, these microspheres are all of the same size, which allows light of a single, blue color to be reflected... As the cells mature, the microspheres lose their uniform size, which causes light of all colors to be reflected, resulting in a whitish hue."

#Algae May Speed Melting of Antarctic Ice eos.org/articles/newly-discove paper: nature.com/articles/s41467-025

"On the basis of sampling and satellite images, the scientists estimated that #AlgalBlooms covered around 20% of the ice cap’s surface. The newly discovered algal communities may represent one of the largest photosynthetic habitats in #Antarctica... algae can contribute up to around 2% of the total daily melting on the ice cap."

Marine #rewilding project sees remarkable results bbc.com/news/articles/c1lp28v7

"Celebrating its 4th anniversary, Sussex #Kelp Recovery Project researchers have reported positive signs of recovery, including an increase in the populations of lobster, brown crab, angelshark and short-snouted seahorse... The project has shown the presence of oyster and honeycomb worms, as well as an increase in Atlantic mackerel, sand eels, and mullets, since the implementation of the byelaw."
