Amerikanischer Biber

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.

Gelbhaarige Bergratte

The common bunomys (<em>Bunomys chrysocomus</em>) is a small rodent species found in diverse terrestrial and aquatic habitats, including tropical forests and adjacent ecosystems. This species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population without immediate conservation concerns. As a member of the family Muridae, the common bunomys is an endemic rodent of Sulawesi, Indonesia, where it typically inhabits montane forest environments at moderate to high elevations. The species often forages on the forest floor, feeding on seeds, fruits, fungi, and invertebrates. Its diet and foraging behavior make it an important contributor to seed dispersal and nutrient cycling in its native forest ecosystems. The common bunomys is typically nocturnal and solitary in its habits, as is characteristic of many rodents in its genus. Biological traits of this species remain poorly documented in the scientific literature.
