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.

Hemitrichia pardina is a myxomycete (slime mould) producing small, stalked, globose to ovoid sporangia with a yellowish to brownish peridium, growing on decaying wood and plant litter in forest habitats. Its internal capillitium threads assist in spore dispersal. This species is widely distributed across temperate and tropical forests and contributes to microbial food webs.
