Protist diversity and phylogeny

A technique is presented to stain, squash, and enumerate thecate dinoflagellate chromosomes using a cellulose incubation and propionocarmine stain. Chromosome numbers for six freshwater armored dinoflagellates (Peridinium cinctum (O.F.M.) Ehrenberg, P. inconspicuum Lemm., P. limbatum (Stokes) Lemm., P. volzii Lemm., P. willei Huit.‐Kaas, and Peridiniopsis polonicum (Wolosz.) Bourrelly) range from 41 (P. inconspicuum) to 210 (P. cinctum). Evidence is presented for dinoflagellate aneuploidy in culture.
