Distributed across Norway and Sweden.

gray wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Chrysochromulina throndsenii is a marine haptophyte alga named in honor of a Scandinavian researcher, reflecting the strong tradition of haptophyte taxonomy in Norwegian and Swedish phycological institutions. The species belongs to the family Prymnesiaceae and shares the characteristic features of the genus: a biflagellate cell body, a haptonema of variable length, and a surface coat of organic scales arranged in overlapping layers. Scale ultrastructure observed under electron microscopy provides the species-specific diagnostic characters essential for accurate identification within this morphologically conservative genus. C. throndsenii is documented from marine coastal waters, consistent with the broader distribution of Chrysochromulina species in temperate North Atlantic environments. As a photosynthetic nanoflagellate, it contributes to primary production and participates in the microbial loop as both a producer and potential mixotrophic consumer of bacteria. The significant role of haptophytes in the marine carbon and sulfur cycles underscores their ecological importance despite their microscopic size. The conservation status of C. throndsenii has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Expanded molecular surveys will be necessary to fully understand its distribution and evolutionary relationships.

gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
