This project was led by Thomas Gable at Northern Michigan University, and was funded by individuals on Experiment, and has produced several publications and outputs [1].
One of the cool highlights is that he found out that wolves tend to ambush beavers near their dams and streams. They will wait downstream and do a sort of stake out. Then when the beaver swims by, the wolf will grab it, because it's harder for the beavers to swim back upstream.
There's another recent publication [2] from University of Washington, where researchers threw salmon carcasses to only one side of a stream for 20 years, and they went back and compared the trees on the banks. They guessed that the nutrients from salmon carcasses (taken out of the stream by bears, wolves, etc) ended up back into the trees and actually caused the trees on one side of the river to grow faster. I bet the natural predation of wolves and beavers does something similar near dams.
Anyways, rivers and streams are cool, and I'm super happy to have funded the project and seen Thomas' map go on the front page of reddit yesterday.

- ravedave5 8y agoThanks for the extra info. This summer in the BWCA we startled a beaver on the bank, the first time I'd seen one so far out of water. It seemed quick but clumsy, it decided hiding behind a small bush was its best defense. I can see why wolves would predate them. I wonder how forest fires play into this as well. We noticed in areas that were burned ~5-15 years ago there were tons of young trees there were so many beavers.
