The vertical (altitudes at 0.1; 0.3; 0.6; 0.9 and 1.2 m above mean sea level - MSL) distribution of Cyanobacteria in the supralittoral zone Cape Kilse-Burun (Meganom Peninsula) was characterized. A total 20 species have been recorded; their number various altitudes varied from 6 to 9 (minimal MSL). As for systematic composition, Oscillatoriophycidae subclass were found on entire range altitudes...

Microcystins (MCs) are potent hepatotoxins, and their presence in water bodies poses a threat to wildlife and human populations. Most of the available information refers to plankton, and much less is known about microcystins in other habitats. To broaden our understanding of the presence and environmental distribution of this group of toxins, we conducted extensive sampling throughout Spain, un...

Cyanobacteria from underexplored and extreme habitats are attracting increasing attention in the search for new bioactive substances. However, cyanobacterial communities from tropical and subtropical regions are still largely unknown, especially with respect to metabolite production. Among the structurally diverse secondary metabolites produced by these organisms, peptides are by far the most f...

A highly divergent 16S rRNA gene was found in one of the five ribosomal operons present in a species complex currently circumscribed as Scytonema hyalinum (Nostocales, Cyanobacteria) using clone libraries. If 16S rRNA sequence macroheterogeneity among ribosomal operons due to insertions, deletions or truncation is excluded, the sequence heterogeneity observed in S. hyalinum was the highest obse...

Winter snowpack is an important source of moisture that influences the development biological soil crusts (BSCs) in desert ecosystems. Cyanobacteria are photosynthetic organisms BSCs. However, responses cyanobacterial community BSCs to snowpack, snow depth and melting still unknown. In this study, we investigated composition diversity under different treatments (doubled snow, ambient removed sn...
