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.

Katagnymene spiralis is a marine, nitrogen-fixing cyanobacterium that forms spiral or coiled filament bundles in tropical and subtropical open ocean environments. It contributes to marine nitrogen cycling through biological nitrogen fixation. Its conservation status is not evaluated.
