Shifts in bacterial community structure during succession in a glacier foreland of the High Arctic.

abstract：:The molecular diversity and community structure of bacteria from the gut of the termite Reticulitermes speratus were analyzed by the sequencing of near-full-length 16S rRNA genes, amplified by polymerase chain reaction. The results of the analysis of 1344 clones indicated a predominance of spirochetes in the gut. Spir...
