Alder

The Alder (Alnus acuminata) is a species in the genus Alnus. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Pinnularia divergentissima is a large, boat-shaped freshwater diatom with strongly diverging costae radiating from the central area to the valve margin. It inhabits acidic, oligotrophic freshwater environments including mountain streams, peat bogs, and soft-water lakes. This photosynthetic diatom is a bioindicator of acidic, nutrient-poor freshwater conditions.
