The traits are listed to the left as radius (r), metatarsal (m), femur (f), tibia (t) and humerus (h) lengths (L), outer diameter (OD) and inner diameter (ID) (e.g., radius length: r(L); radius outer diameter r(OD); radius inner diameter r(ID). The percent variation for each PC heads a column listing the loadings for each trait.
