Found a nice vitricolous lichen yesterday in New York. I'm assuming it's some sort of rock shield (Xanthoparmelia) but not sure which one. Per Harris (2004) there are 15 different species in the state. #lichen #glass #nature #fungi #algae #inaturalist inaturalist.org/observations/2

first Prototaxites fossil was discovered in 1843, scientists haven't been sure whether they were a plant, fungus or even a type of . However, chemical analyses…suggested they were likely a giant ancient fungus.

…Prototaxites might not have been a humongous after all — rather, it may have been an entirely different and previously . The study has not yet been peer-reviewed.

Kubota Garden is a Japanese Garden in the southeast corner of Seattle, Washington. Created in 1927 by Fujitaro Kubota, Kubota Garden is all the more impressive, not only for its beauty, but for the fact that Mr. Kubota was able to create it despite the discrimination endured by Asian Americans during the early 20th century. Worse yet, in 1942, Fujitaro Kubota and his family were sent to Minidoka Internment Camp (a.k.a. Minidoka Concentration Camp). Amazingly, after being released from internment at the end of World War II, Fujitaro Kubota went back to creating his extraordinary garden.

Autotrophs are organisms which use pigments for photosynthesis by absorbing light at specific wavelengths. The dominant chlorophyll-a absorbs #light in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why #algae is green. Phycocyanin, an accessory #pigment in #cyanobacteria, absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.

#DomoicAcid can also accumulate in #shellfish & small #fish that feed on the #algae, leading to poisoning in larger #marine animals & humans who consume contaminated #seafood.

Addressing the urgent need to monitor the impact of harmful #AlgalBlooms on #MarineSpecies requires collective strategies. The destructive #California #wildfires, which have contaminated our #oceans & are threatening #MarineLife, serve as a critical call to action for collaborative efforts to protect marine environments….

#Crisis On The Coast: #DomoicAcid Poisoning Strands 140 #SeaLions & 50 #Dolphins On #California Beaches
The recent influx of #marine #wildlife affected by domoic acid poisoning off the coast of Southern California underscores a critical #environmental crisis, w/≧140 sea lions suffering from this debilitating poison & reports of at least 50 stranded dolphins along local beaches.

Pink snow tints the edges of Antarctica english.elpais.com/science-tec

"The #algae that covers Mount Reina Sofía in patches is Sanguina nivaloides, a species first described in 2019. The meaning of its scientific name in Latin is eloquent: blood in the snow. Each creature has a single cell, about 20 thousandths of a millimeter in size, with a molecule inside that gives it its characteristic red color: #astaxanthin... the same pigment that produces the color of salmon"
