Microcystins and anatoxin-a in Arctic biocrust cyanobacterial communities
In the polar regions cyanobacteria are an important element of plant communities and represent the dominant group of primary producers. They commonly form thick highly diverse biological soil crusts that provide microhabitats for other organisms. Cyanobacteria are also producers of toxic secondary m...

In the polar regions cyanobacteria are an important element of plant communities and represent the dominant group of primary producers. They commonly form thick highly diverse biological soil crusts that provide microhabitats for other organisms. Cyanobacteria are also producers of toxic secondary metabolites. In the present study we demonstrated that biocrust-forming cyanobacteria inhabiting the Kaffiøyra Plain, the north-west coast of Spitsbergen, are able to synthesize toxins, especially microcystins (MCs, from 0.123 to 11.058 μg MC-LR per g dry weight, DW) and anatoxin-a (ANTX-a, from 0.322 to 0.633 μg ANTX-a per g DW). To the best of our knowledge, this is the first report on the presence of ANTX-a in the entire polar region. The occurrence of cyanotoxins can exert a long-term impact on organisms co-existing in biocrust communities and can have far-reaching consequences for the entire polar ecosystem. |
