Název v původním jazyce

Morphological diversity of coiled planktonic types of the genus Anabaena (cyanobacteria) in natural populations ? taxonomic consequences

Popis výsledku v původním jazyce

Morphology of 61 planktonic populations of the genus Anabaena with coiled trichomes was studied under natural conditions. The samples were collected from Czech water bodies, representing all morphospecies that have previously been reported from the CzechRepublic. Using the Principal Component Analysis (PCA) and paired t-tests, the existence of clear morphological boundaries of these morphospecies was tested. The only clearly delimited morphospecies was A. compacta, the other morphospecies formed a morphological continuum and no clear-cut boundaries could be observed. Defined groups of morphotypes were thus proposed for practical usage, specifying also the morphological criteria (A. mendotae & A. sigmoidea, A. flos-aquae & A. spiroides, and A. circinalis & A. crassa). Identification at lower taxonomic level is not feasible based only on morphology. Moreover, A. lemmermannii taxon appears to be morphologically heterogeneous and probably needs a taxonomic revision.
