Those of the Forest - Wallace Byron Grange

This classic (1953) work on the ecology of the north woods is a delightful and very readable narrative on the life of plants and animals and their interrealtionship in the north woods. It's a tough life.  Grange was located in Wisconsin and spent his entire life studying life systems there and working to preseve their natural habitat. I thoroughly enjoyed his narrative as to how the myriad of plants and animals interacted and survived - or didn't - through the seasons in the north woods.  The book is centered on the life cycle of snowshoe rabbits or what I assme are snowshoe hares although he never used the term hare. I believe the terms are interchangable. Please corrct me if I'm wrong. While I did enljoy the book and learned plenty, one thing stood out and really bothered me. In fact, it sort of makes me question his expertise throughout the book. It's my undetstanding that the snowshoe rabbit/hare's entire life cycle is inexorably tied to that of the Canada lynx.  From what I've read and researched, the populations of the two species are totally dependent on each other. When the snowshoe hare's numbers increase, so do those of the lynx.  When the hare's populations crashes, so does the lynx population.  Nowhere in the book, other than a few passing references to the "wildcat" does Grange mention lynx.  I find this curious in book that is otherwise so detailed, seemingly authoritative and highly regarded.  Any comments on this seemingly blatant omission?

Still, I enjoyed the book and recommend it.
