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.

Nitzschia flexa is a pennate diatom (class Bacillariophyceae) with a characteristically curved or bent raphe system that gives the genus its distinctive appearance.

As a photosynthetic microalga, it plays a foundational role in aquatic food webs and primary production.
