Morphometric approach in defining the surface area of the thallus in multicellular alga Callithamnion corymbosum (J. E. Smith) Lyngb

The multicellular alga Callithamnion corymbosum was chosen as a model for the estimation of its surface area. Here we present the equations to calculate the surface area (S2, cm2) at the axis (0k) as well as at different levels of the branching (k). We provide regression equations, defining the relation between surface areas of the second- (S2) and third-order (S3) branches to the length of the axial structures of the corresponding orders of the branching ( l 02, l 03, см): l ogS2 = -0.702 + 1.105 log l 02; l ogS3 = -0.728 + 1.564 log l 03.
