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.

Eunotia elegans is a pennate diatom in the family Eunotiaceae, distinguished by its arcuate (curved) frustule with a short, marginal raphe at each pole. It inhabits acidic, soft-water lakes, peat bogs, and oligotrophic freshwater environments where it contributes to periphyton communities. The genus Eunotia is considered a useful indicator of water acidity and low ionic conductivity.
