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.

Pinnularia divergentissima is a large, boat-shaped freshwater diatom with strongly diverging costae radiating from the central area to the valve margin. It inhabits acidic, oligotrophic freshwater environments including mountain streams, peat bogs, and soft-water lakes. This photosynthetic diatom is a bioindicator of acidic, nutrient-poor freshwater conditions.
