Photoinhibition and Recovery in Lake Akan Marimo

Caption

The marimo (Aegagropila brownii), a nationally designated Special Natural Monument of Japan, inhabits Lake Akan in Hokkaido, where environmental conditions fluctuate drastically with the seasons. Of particular concern is the period immediately after ice melt in early spring (right), when low water temperatures coincide with strong sunlight, posing a risk of severe damage to photosynthetic activity.
