Autumn Snowflake

The Autumn Snowflake (Acis autumnalis) is a species in the genus Acis. It is currently classified as Least Concern on the IUCN Red List. Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Chrysolykos skujae is a chrysophyte flagellate in the genus Chrysolykos, named for the Latvian phycologist Helmut Skuja, whose foundational surveys of Swedish and Scandinavian freshwater algae during the 1940s and 1950s established the basis for modern knowledge of northern European chrysophyte diversity. The species belongs to the class Chrysophyceae and shares the genus features of a loricate or semi-enclosed flagellate cell with photosynthetic capabilities. Like other Chrysolykos species, C. skujae is found in freshwater plankton communities, particularly in oligotrophic and mesotrophic lakes of Scandinavia. The genus occupies a somewhat intermediate morphological position between strictly free-swimming chrysophyte flagellates and more rigid loricate forms. Chrysophytes in general are sensitive to water chemistry changes, particularly pH and nutrient concentrations, and serve as environmental indicators in lake monitoring. C. skujae may be capable of mixotrophic feeding, supplementing photosynthesis with phagotrophic ingestion of bacteria. The IUCN has not assessed the conservation status of this species, which is listed as Not Evaluated. The Chrysolykos genus requires more detailed molecular phylogenetic study to clarify its relationships within the chrysophyte phylogenetic tree.
