Some #weird #algae growing over everything in the low #creek #green #photography

University of Missouri: Lab-grown algae removes microplastics from water. “In a recent study, [Professor Susie] Dai used genetic engineering to create a new kind of algae that produces a volatile natural oil called limonene — the same chemical that gives oranges their refreshing scent. Limonene makes the new algae water-repellent. Because microplastics are also water-repellent, the two come […]

ARCTIC MEAL
Course 1 // Kelpsalad, kelp kaviar, coral flan, soya aged egg yolk, smoky wasabi foam

For each course of the dinner, we identified a selection of key ingredients that formed the foundation of the dish. Complementary ingredients were then carefully chosen to complete and refine each course.

In northern and Arctic regions, #ALGAE are strongly affected by climate change. Rising sea temperatures, melting sea ice, and ocean acidification alter light conditions, nutrient cycles, and habitats. Ice-dependent microalgae lose their living space as sea ice retreats, while COLD-WATER #KELP FORESTS are stressed by warming and increased storm activity.

ARCTIC COLD-WATER #CORALS are affected by the climate crisis through a combination of environmental and human-driven changes. Rising ocean temperatures disrupt the narrow thermal tolerance of these corals, negatively affecting their growth and reproduction. At the same time, ocean acidification, which is particularly pronounced in cold waters, hampers the formation of their calcium carbonate skeletons and weakens existing reef structures.

WHEAT farming in northern regions is threatened by the climate crisis mainly through more frequent extreme weather. Warmer winters reduce snow cover, which exposes winter wheat to frost damage. Increased rainfall causes waterlogging and fungal diseases, while heat waves during summer shorten grain filling and lower yields. We used the #wheat to create the coral flans.

We served SWEDISH WHITE WINE with the course. Due to global warming, it is now possible to grow wine in southern Sweden.

🧊 As a result of global warming, the West Antarctic Ice Sheet is shrinking. During earlier interglacials, a similar behaviour had an unexpected result on algae growth in the adjacent Southern Ocean, a new study by scientists from the University of Oldenburg, published in Nature Geoscience, reveals.

High-contrast image of dried algae draped over rocks and dirt in a dry creek bed. The algae formed while there was water in the creek, and as the water evaporated, the algae draped over the rocks and dirt. In this image, the algae looks like white fibers forming a tight net. The dirt and rocks under the algae are very dark. On top of everything are strands of dry grass. Laguna Lake Open Space, San Luis Obispo, California

Great to see #algae recognised - but missing the call to #climateaction

Not moss (everyone’s favorite) but something much like it.

A wet rock face covered with bright green algae draping downward all over it, lit up by angled sunlight. There are areas where the gray rock and sand are seen through gaps in the algae, and it’s also got dark shadows in divots and crevasses all across the rock, alternating between the mossy coverings of the algae.

#GreatGreenWall 2.0: #China is #geoengineering #deserts with blue-green #algae
These specially selected strains of #cyanobacteria can survive extreme heat and drought for long periods, according to China Science Daily on Thursday. When rain finally comes, they spring to life, spreading rapidly and forming a tough, biomass-rich crust over the sand. This living layer stabilises the dunes and creates the perfect foundation for future plant growth.

Earth-like #planets orbiting small, red #stars known as M-dwarfs are often considered the right size and at the right distance from their sun to harbor #life.

However, these worlds may not have the right kind of light to support multicellular organisms.

Here on Earth, #plants and #bacteria turn sunlight into energy through #photosynthesis, releasing oxygen as a byproduct.

During the Great Oxidation Event around 2.3 billion years ago, significant quantities of #oxygen began to accumulate in our #atmosphere, eventually reaching levels capable of supporting multicellular life.

According to our understanding, a similar process would have to occur on other planets for complex life to start evolving.

#Photosynthesis requires a specific kind of light from 400 to 700 nanometers that plants, #algae and #cyanobacteria need to thrive.

Although it was known that light from M-dwarf stars like TRAPPIST-1 is mostly #infrared, which falls outside this range, what was unknown was how this would slow down the evolutionary clock.

By comparing light from these red stars to our own sun and modeling the oxygen production of various #bacteria, redearchers calculated that because these stars produce so little usable energy, the accumulation of oxygen would be far too slow.

Potentially, on a #planet like TRAPPIST-1e, it would take 63 billion years in a worst-case scenario to reach the oxygen levels seen on Earth through photosynthesis.

"Heavy rainfall triggers turbulence that stirs the lakebed, resuspending dormant algal cells and nutrients... The #algae form concentrated columns of biomass that begin to climb... After a delay of one to two days, these plumes hit the surface and expand, finally becoming visible... By detecting these ghost plumes as they leave the sediment, water managers can shift to proactive prevention"

RE: https://ecoevo.social/@DrPlanktonguy/115554189599941981

When large quantities of brown #algae are repeatedly #washedashore over an extended period, my first question as an acarologist is naturally which interesting, and possibly phoretic, terrestrial #organisms, such as mites, are specifically #adapted to these #conditions. But these algae are a phenomenon with #ecological #repercussions that must be understood. It is particularly interesting, thus, that it is the #phosphorus content that affects #symbiotic #cyanobacteria, which promote algal growth
