Habitat & Geographic Range

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).

Common Mountain Bush-cricket

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

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.

Common Mountain Bush-cricket

The Common Mountain Bush-cricket (<em>Antaxius pedestris</em>) is an insect in the genus <em>Antaxius</em>, belonging to the family Tettigoniidae within the order Orthoptera. This species is classified as Least Concern on the IUCN Red List, suggesting its populations are currently stable. It is typically found across virtually all terrestrial and freshwater habitats within its range. As a bush-cricket, <em>Antaxius pedestris</em> belongs to a group characterized by long antennae, typically exceeding body length, and the ability to produce sound through stridulation — rubbing the wings together. Bush-crickets are generally omnivorous, feeding on plant material, small invertebrates, and occasionally other insects. The "mountain" designation in its common name reflects an association with elevated, rocky or montane habitats, which are typical for members of this genus in Europe. Detailed biological traits such as average lifespan, body dimensions, and weight are not widely documented for this species in available records. Further taxonomic and ecological research may better define the full distribution and habitat preferences of this species.
