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.

Suillus amabilis is a mycorrhizal bolete mushroom in the family Suillaceae, forming symbiotic associations with conifers, particularly pines. It produces colorful fruitbodies with a slimy cap surface and pores instead of gills on the underside, characteristic of the genus. Its mycorrhizal relationship is essential for nutrient exchange between fungus and host tree in forest ecosystems.
