FIG. 2 in Habitat Usage, Dietary Niche Overlap, and Potential Partitioning between the Endangered Spotted Turtle (Clemmys guttata) and Other Turtle Species

FIG. 2. Biplots of d15N and d13C for four turtle species at all sites with ellipses around each species (filled squares/solid black line ¼ Kinosternon subrubrum, filled triangles/solid gray line ¼ Chrysemys picta, open circles/gray dashed line¼ Chelydra serpentina, filled diamonds/ lack dashed line ¼ Clemmys guttata). There is a large overlap in isotopic compositions for all species, resulting in no significant differences in isotopic niche space between species (see text).
