Shape variation among ecotypes and treatments and its correlation to survival rate. A relative warp analysis describing the first two axes; RW1 and RW2. Circles illustrate individuals of the S-ecotype while triangles illustrate E-ecotype snails. Shading indicates treatment group. Larger symbols represent individuals that survived the natural transplant experiment. Deformation grids for each ecotype are ordered from the top for "Crab", "Control" and "Wave" treatments in each ecotype.
