Range

Distributed across Brazil, 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 bergenensis is a unicellular marine haptophyte named after Bergen, Norway, near where it was first described, reflecting the strong tradition of phycological research centered on the Norwegian coast. It belongs to the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae — a group of golden-brown microalgae distinguished by possession of a haptonema alongside two flagella. The haptonema is a flagella-like appendage unique to haptophytes that functions in prey capture and temporary substrate attachment. C. bergenensis is a nanoplankton species inhabiting coastal marine and occasionally brackish waters, and has been documented from Norwegian and Swedish coastal regions as well as from South American waters including Brazil, indicating a broader distribution than its type locality might suggest. In oligotrophic to mesotrophic marine environments, Chrysochromulina species including C. bergenensis contribute to picoeukaryotic and nanoeukaryotic primary production. The cell surface is ornamented with siliceous or organic scales whose morphology is species-diagnostic. Mixotrophy — the ability to both photosynthesize and ingest particulate food — is common across the genus and likely occurs in this species. C. bergenensis has not been assessed under IUCN Red List criteria and is classified as Not Evaluated. In ecological terms, haptophytes occupy key roles in oceanic carbon export, nutrient cycling, and as prey items for heterotrophic protists and copepods in temperate and boreal Atlantic food webs.

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.
