Canadian beaver

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.

Curtobacterium ammoniigenes is a Gram-positive actinobacterium in the family Microbacteriaceae, isolated from soil and plant-associated environments. It is aerobic, rod-shaped, and motile by a single flagellum, and is capable of producing ammonia from organic nitrogen compounds. The genus Curtobacterium is commonly found in agricultural soils and the phyllosphere of various crop plants.
