| Abstract | The biogeographic distribution of Lingulodinium machaerophorum - cyst of the corresponding red tide forming motile dinoflagellate Lingulodinium polyedrum - is delineated by the ratio between summer salinity and temperature (S/T). The confinement to this ratio can be related to a physicochemical process which determines the morphological variation of the cyst and inhibits formation of the cyst outside the range of tolerable S/T ranges. This finding has far reaching implications for studies on harmful algal blooms, paleoclimate reconstructions using dinoflagellate cysts, interpretation of evolutionary trends and palaeobiogeographical zonations and possibly also of other plankton groups. |
