Micrographs of metaphyton mat materials at 100x (A) and 400x (B) magnification. Mats were a complex assemblage of several different species of filamentous cyanobacteria as well as unicellular microalgae, bacteria, protists, and sediments.

Total ion chromatogram of a crude biomass extract and the extracted ion chromatogram for dihydroanatoxin-a at 168.138 m/z (A). The EIC had two peaks eluting between 0.6 and 1.4 min, which correspond to the naturally-occurring isomers as shown by Puddick et al. . The mass spectrum (B) shows dhATX eluting at 0.77 min, which had a parent ion at 168.1386 m/z using electrospray ionization in positive mode. The observed mass of analytes was within 0.5 ppm of the calculated mass (168.1383 u) for [dhATX + H]+.
