Spatial patterns and biodiversity of algae assemblages, and the effect of environmental factors on species composition were studied in an ephemeral pristine stream. Samples were taken along a longitudinal stream transect beginning at the source. At each sampling site, different types of substrates were collected and water chemistry investigated. A total of 109 infrageneric algal taxa were identified with diatoms being the most diverse group (85 taxa). Characteristic diatom species included: Chamaepinnularia soehrensis, Diadesmis laevissima, D. paracontenta, Eunotia exigua agg., E. incisa, E. ursamaioris, Fragilariforma virescens, Microcostatus krasskei, Pinnularia silvatica agg., and P. subcapitata agg. In addition, green algae of the Chlococcaceae agg., and Klebsormidium flaccidum were also abundant. Composition of algal assemblages were primarily influenced by the type of substratum (20.5% variance explained, p = 0.001) and by the spatial distance from the stream origin (3.0%, p < 0.05). Variation in species composition explained by conductivity, pH, temperature and nitrogen was relatively low (10.1%).

More about this publication?
  • Nova Hedwigia is an international journal publishing original, peer-reviewed papers on current issues of taxonomy, morphology, ultrastructure and ecology of all groups of cryptogamic plants, including cyanophytes/cyanobacteria and fungi. The half-tone plates in Nova Hedwigia are known for their high quality, which makes them especially suitable for the reproduction of photomicrographs and scanning and transmission electron micrographs.
