Covariations between Shell-Growth Parameters and the Control of the Ranges of Variation of Functionally Relevant Shell-Shape Parameters in Bivalves: A Theoretical Approach
Table 2
Consequences on the magnitude of variations , , and of the functionally relevant parameters , , and , according to the type of covariation between growth-related parameters , , and . Arrows pointing upward (resp., downward) stand for widened (resp., narrowed) ranges of variations; the sign “=” stands for a nonaffected range of variations as compared to what would be these ranges in case of mutual independence between , , and .
