Effects of Substrate Size and Orientation on Quadrupedal Gait Kinematics in Mouse Lemurs (Microcebus murinus) by Shapiro, Liza J., Kemp, Addison D., Young, Jesse W.

“…ABSTRACT As the smallest living primate, the mouse lemur is a suitable model for reconstructing the locomotor mechanisms by which primate ancestors might have…”

Morphological and functional differentiation in the lumbar spine of lorisids and galagids by Shapiro, Liza J.

“…The striking contrast in positional behavior exhibited by lorisids (slow quadrupedalism/suspension) and galagids (leaping/quadrupedalism) is well reflected in…”
