Assessing patterns of morphological and physiological trait variations across heterocytous cyanobacteria at cellular and population levels

Heterocytous Cyanobacteria show high trait variation at the cellular, organismal, and population levels. Members of this group can produce specialized cells such as akinetes and heterocytes that influence their ecology, including bloom development and population survival. This study characterizes pa...
