I'm working on a project examining the evolution of arboreal locomotion in
quadrupedal mammals. The main focus of this study is a comparison of
substrate reaction forces and torques among species which are specialized
for arboreal locomotion and among generalists. Can anyone give me some
insight into finding quadrupedal arboreal mammals, preferably below 500g in
body mass? I think a species of dormouse might be a good place to start,
but I'm having a much harder time finding a vendor than I expected.

Thanks much,
