Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.

Nitzschia angularis is an elongated, pennate freshwater diatom with angular poles and a distinctive raphe positioned along the keel of the frustule. It inhabits eutrophic to mesotrophic freshwater environments including rivers, ponds, and nutrient-enriched lakes. This photosynthetic diatom is associated with moderately enriched freshwater conditions.
