Range

Found across Europe (6 countries). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Chrysosphaerella coronacircumspina is a colonial chrysophyte alga in the genus Chrysosphaerella, family Chromulinaceae. Its compound specific epithet corona-circumspina (Latin: crown of surrounding spines) references the distinctive arrangement of silica spines forming a ring or crown around each cell in the colony. Each cell in a Chrysosphaerella colony bears both flat siliceous scales and long, projecting spines, with the spine arrangement being species-specific and taxonomically diagnostic. The colonial organization is held together by organic matrix material, creating a spherical or semi-spherical aggregate visible under light microscopy. C. coronacircumspina is found in freshwater phytoplankton communities in Scandinavia, consistent with the broader distribution of Chrysosphaerella in cold-temperate and subarctic lakes. The silica structures produced by Chrysosphaerella cells are deposited in lake sediments upon cell death, creating millennial-scale paleoenvironmental archives. Chrysophytes are sensitive to lake acidification, nutrients, and temperature, making them useful climate proxies in paleolimnological research. The species has not been assessed for conservation status by the IUCN and is listed as Not Evaluated.

Eurasian badger

Eurasian badger (Meles meles) 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.
