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.

Sphingobium amiense is a Gram-negative aerobic rod with the ability to degrade nonylphenol and related endocrine-disrupting compounds. It has been isolated from activated sludge and polluted soil environments. This bacterium plays a role in the degradation of synthetic surfactants and phenolic pollutants in wastewater treatment systems.
