Covariations between Shell-Growth Parameters and the Control of the Ranges of Variation of Functionally Relevant Shell-Shape Parameters in Bivalves: A Theoretical Approach
Figure 1
Definition of two alternative sets of descriptors of the shell outline. (a) The three growth-based parameters: apical angle ; differential growth index ; dissymmetric growth index ; (b) the three functionally relevant parameters: elongation , dissymmetry , and ventral convexity .
