волк

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.

Pelonema tenue is a slender, colorless filamentous bacterium in the order Achroonematales, found in the stratified, oxygen-depleted layers of freshwater lakes and brackish water bodies. It forms straight or slightly curved trichomes of narrow diameter in microaerobic to anaerobic zones. As a chemoheterotrophic organism, it participates in carbon cycling in hypolimnetic waters.
