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.
Physarum viride is a vibrantly coloured myxomycete (slime mould) producing small, bright yellow-green sporangia on decaying organic matter including dead wood, leaves, and litter in forest habitats. Like all Physarum species, it spends part of its life as a multinucleate plasmodium that creeps across substrates to engulf food particles. This species is found in moist woodlands across temperate and tropical zones.
