Isle Royale would be a good candidate for this kind of study. It's a small island in the middle of Lake Superior that has its own isolated wolf population. They take a lot of data from the wolf and moose populations, and it wouldn't be surprising if they had some way to track/estimate weight. I know the research facilities there were the target of severe budget cuts several years ago. It's a shame, because this is an example of where other, unrelated research would benefit from the basic research of an environment mostly untouched by humans. http://en.wikipedia.org/wiki/Isle_Royale http://en.wikipedia.org/wiki/Isle_Royale
