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.

Orbilia comma is a minute discomycete fungus producing tiny, translucent to pale yellowish cup-shaped fruiting bodies on decaying wood and plant debris in humid forest settings. It belongs to a genus of small, inconspicuous fungi that play a role in decomposing organic material on the forest floor. Near Threatened, its status reflects sensitivity to woodland management changes and habitat loss.
