More on Theoretical Morphospace and Its Relation to Freshwater Gomphonemoid-cymbelloid Diatom (bacillariophyta) Lineages


All forms from hypothesized gomphonemoid-cymbelloid lineages were constructed using three-dimensional (3D) parametric equations with the same boundary intervals for all forms. To construct a theoretical morphospace, the absolute value of the Riemann sum of differences between pairs of forms in terms of surfaces in the x-, yand z-directions was determined… (More)
