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.

Fuligo leviderma is a myxomycete (plasmodial slime mould) in the family Physaraceae, producing pale, smooth-coated aethalia on decaying wood and plant litter in moist forest environments. Like other Fuligo species, it passes through a conspicuous plasmodial stage before forming the spore-bearing aethalium. Its conservation status is not evaluated.
