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 2
Statistically significant covariances between growth-based parameters. (a) Interspecific variations within the genus Donax (36 species): a negative covariance between and (, ; no covariance between and : , ). (b) Intraspecific variations within the Donax trunculus (51 individuals): a positive covariance between and (, ; no covariance between and : , ).
