Short summary
Morphology of dinoflagellate cysts (which are valuable tools in deciphering past environmental and climate changes) depends not only on genetics, but also on a range of environmental factors. We review frequently occurring (Black Sea) morphotypes and propose use of matrices to record gradual variation between endmember forms as a pragmatic approach until cyst–theca studies and genetic sequencing can demonstrate relationships between genetically and environmentally controlled morphotypes.
