Rising lake temperatures are threatening unique marimo, a type of spherical green algae, by creating unfavorable conditions for their growth and survival. Marimo thrives in cool, low-temperature aquatic environments. As the water temperatures increase due to climate change, it becomes less suitable for marimo. Higher temperatures can disrupt their ecological niche, potentially leading to reduced growth rates and the degradation of their spherical shape. This, in turn, jeopardizes the unique and delicate ecosystem that marimo creates in these cold-water environments.
