Covarying Shell Growth Parameters and the Regulation of Shell Shape in Marine Bivalves: A Case Study on Tellinoidea
Figure 5
The ventral convexity K plotted against the growth-based parameters α and ρ, for 36 species within the genus Donax (a) and 49 species within the genus Tellina (b)—black triangles: apical angle α (°/100); grey dots: differential growth index ρ. The increase of α and decrease of ρ with growing K for Donax are highly significant () and significant (), respectively. For Tellina, the trends are not significant ( for both).
