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.

Staphylococcus simiae is a coagulase-negative Gram-positive coccus in the family Staphylococcaceae, originally isolated from South American squirrel monkeys. It is an opportunistic commensal inhabiting the skin and mucosal surfaces of its primate host. Its discovery extended our knowledge of Staphylococcus diversity across non-human primate species.
