Fig. 1: Principal component analysis of the duck breeds’ skeletal and soft tissue parameters.

From: Testing the form-function paradigm: body shape correlates with kinematics but not energetics in selectively-bred birds

Fig. 1

Linear skeletal measurements are presented in (a), and final skin segment volumes in (b), where each point represents a distinct individual. The biplots in both panels represent variable correlations with each principal component, note that these have been offset from 0,0 and increased in size (doubled), for legibility. Variable abbreviations are as follows, for a: THL thigh length, SHL shank length, TML tarsometatarsal length, PEL pes length, HLL total hindlimb length, HUL humeral length, FAL forearm length, CML carpometacarpal length, MAL manus length, FLL total forelimb length, NEL neck length, SHW shoulder width, HPW hip width, GAL gleno-acetabular length, STL sternum length. For b: HDSV head volume, NSV neck volume, TOSV torso volume, HUSV humeral volume, FSV forearm volume, MASV manus volume, THSV thigh volume, SSV shank volume, MTSV tarsometatarsal volume, PSV pes volume.
