Fig. 4 in Covariation In Shapes Between The Sternum And Pelvis In Aquatic Birds With Different Locomotor Modes

Fig. 4. Covariation between lateral projections of the sternum and pelvis estimated with the standard PLS analysis. Phylogenetic relationships are projected onto the PLS1 morphospace. Grey wireframe represents mean shape. Species points are marked by locomotor categories (FP — foot-propelled divers, WP — wingpropelled divers, SSW — surface swimmers) and numbers: 1 — Cygnus cygnus, 2 — Cygnus olor, 3 — Cygnus melancoryphus, 4 — Chen caerulescens, 5 — Anser erythropus, 6 — Branta ruficollis, 7 — Branta bernicla, 8 — Alopochen aegyptiaca, 9 — Tadorna ferruginea, 10 — Aix sponsa, 11 — Aix galericulata, 12 — Mergellus albellus, 13 — Mergus merganser, 14 — Bucephala clangula, 15 — Phalacrocorax carbo, 16 — Phalacrocorax pelagicus, 17 — Phalacrocorax atriceps, 18 — Pelecanus crispus, 19 — Eudyptes chrysolophus, 20 — Porphyrio porphyrio, 21 — Fulica atra, 22 — Gallinula chloropus, 23 — Podiceps cristatus, 24 — Aethia psittacula, 25 — Uria aalge, 26 — Alca torda.
