Bacterial dominance of phototrophic communities in a High Arctic lake and its implications for paleoclimate analysis / Dermot Antoniades, and 7 others.
Title: | Bacterial dominance of phototrophic communities in a High Arctic lake and its implications for paleoclimate analysis / Dermot Antoniades, and 7 others. |
Author(s): | Antoniades, Dermot. |
Date: | 2009. |
In: | Polar Science. (2009.), Vol. 3(3) (2009) |
Abstract: | Investigates phototrophic communities in meromictic, perennially ice-covered Lake A, on Ellesmere Island in Canadian High Arctic using pigment analysis supplied by high performance liquid chromatography. Analysis shows that Lake A has distinct phototrophic communities in its oxic and anoxic layers. Pigment analyses indicate that phototrophic biomass in upper, oxic waters is dominated by picocyanobacteria, while in lower, anoxic layer photosynthetic green sulphur bacteria are dominant. |
Notes: | Polar Science. Vol. 3(3) :147-161 (2009). In special issue Kanda MERGE. |
