Canadian beaver

Habitat

Typically found in grasslands, forests, and vegetated habitats.

Range

Widely distributed across Europe (15 countries), North America (United States), and South America (Argentina, Chile).

Aspergillus niger is a ubiquitous black-spored mold with a globally cosmopolitan distribution, recognized by its dense black conidial heads. It inhabits soil, decaying organic matter, and indoor environments worldwide across tropical, subtropical, and temperate regions. This saprotrophic fungus decomposes complex organic matter and is commercially important for citric acid production and enzyme manufacturing.

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.
