Algae Bloom: 'Blood Message' of Snow Algae on Mountains

214

For the past few years, the slopes of the Alps mountains of France have started showing dark colors in the summer season. During this, the snow there sometimes turns red, sometimes orange or pink. Local people call it 'Song de Glacier' or 'Glacier Blood' and people walking in the mountains have also started calling it 'Watermalen Snow'.



Warning of deteriorating ecology and shrinking glaciers, snow turning red in the Alps mountains

According to scientists, the snow at a high altitude is being formed due to the rapid growth of algae (algae bloom). That's why the snow is changing color in the Alps mountains. Their blood message can range from destroying the ecosystem to accelerating the rate of glacier shrinkage.

Researchers say that although algae blooms are natural, human factors may also be responsible. This is the reason why survey and sampling work has started on algae present in the Alps.

This research, developed this week in Frontiers in Plant Science, has also yielded some preliminary findings. The author of the research, Adeline Stewart, says that algae are plant-like bacteria that are the basis of the entire ecology.

Due to their photosynthetic prowess, they produce the bulk of the world's oxygen and form the basis of the food chain. But sometimes they themselves grow too much quantitatively. This worsening imbalance causes it to release blood-red toxins, which appear as glacier blood or watermelon snow.
