Through the winter months Through spring, through spring, the French Alps are covered in white snow. However, as spring progresses into summer it is when the Stoic hills begin to show signs of blushing. Some areas of the snow turn vibrant colors: deep red or rusty orange. Lemonade is pink. Locals refer to it as’sang de glacier”‘, or “glacier blood’. Some visitors go on a watermelon snow.
Actually this blush originates from an embarrassing algae. In recent times, alpine ecosystems across the globe have witnessed a return of the growth of snow algae. It’s a stunning oddly toned mixtures of these typically invisible creatures.
Even though there isn’t an adequate comprehension of what is happening to snow algae it’s most likely not a good indicator. Researchers have started to research algae from the Alps to learn more about which species are found there, how they live, and what they might do to push the edge of blooming. The first results are recently published in Frontiers in Plant Science.
Small, but powerful, algae-like plant-like bacteria are the ‘basis for all ecosystems’ declared Adeline Stewart who is a doctoral candidate studying at Grenoble Alpes University in France and the author on the research. Algae generate through their photosynthetic ability an enormous amount of the oxygen that is produced in the world and form the basis of all food webs.
But sometimes they get too much and they upset balance. It could cause poisonous red tides oily freshwater blossoms , or disturb glacial blood.Read More: Greece builds a 25-mile fence to keep out Afghan refugees
While it’s not entirely clear which blossoms it is but the color, usually red, but occasionally yellow, gray, or even green originates from the pigments and other molecules that algae of the snow use to shield themselves from UV light. These colors absorb more light which causes the snow to melt more quickly. This can alter the ecology’s dynamics and accelerate the shrinkage of glaciers.
Inspiring by the increasing number of reports about the phenomenon, scientists from a variety of alpine institutes decided to concentrate their efforts to algae species living in isolated habitats, focusing on the ones “growing right next to them,” said Eric Marechal director of the laboratory for plant biology located at Grenoble Alpes University. , said. and the leader of the project.
As a wide variety of algae thrive and flourish in the mountains, researchers started a count in different regions in the French Alps to discover the species that thrive in which areas. They collect soil samples taken from 5 mountains distributed over various heights, and then search for DNA from algal species.
The researchers found that a variety of species prefer certain heights, and they likely were able to adapt to the climates which are found there. One genus that is important, named Sanguina can reach to just 6,500 feet.
Researchers also brought a few species back to the lab to study the possibility of flowering inflorescences. The blooms of algae occur naturally. the first documented report of blood from glaciers is via Aristotle, who guessed that the snow caused hairy red worms to develop.

Human-caused causes can also exacerbate these outbreaks and cause them to become more frequent. Extreme weather, excessively hot temperatures, and the influx of nutrients from sewage and agricultural runoff all play a part in freshwater and algae in the ocean.
To determine if this is true for the blood of glaciers scientists exposed algae to a high amount of nutrients, including nitrogen and the phosphorus. So far, they’ve discovered nothing of note however, they plan to keep this test going as the researcher, Ms. Stewart said.
Its limitations in DNA samples make it clear that even this study provides only a fragmented view of the life that exists beneath and in the snow, claimed Heather Maughan, a microbiologist and research scholar at the Ronin Institute in New Jersey. But it has revealed the “incredible range’ of algae. it shows the lack of knowledge about algae, and their potential to serve as an indicator of the state of our ecosystem’ she added.
In the next year, scientists will monitor the expansion of species throughout period of time. It could affect the overall ecological health according to the researcher, Ms. Stewart said. They will also attempt to find out if patterns in temperature correlate with flower patterns, and will begin to compare species compositions with snow that is white and colorful. They hope eventually to unravel the message in blood red.
“There is so little that we are aware of,” she said. “We must go deeper.”
