Vertical distribution of microbial communities in a perennially stratified Arctic lake with saline, anoxic bottom waters
Meromictic lakes are useful biogeochemical models because of their stratified chemical gradients and separation of redox reactions down the water column. Perennially ice-covered meromictic lakes are particularly stable, with long term constancy in their density profiles. Here we sampled Lake A, a deep meromictic lake at latitude 83°N in High Arctic Canada. Sampling was before (May) and after (A...
متن کاملThe vertical distribution of phytoplankton in stratified water columns.
What determines the vertical distribution of phytoplankton in different aquatic environments remains an open question. To address this question, we develop a model to explore how phytoplankton respond through growth and movement to opposing resource gradients and different mixing conditions. We assume stratification creates a well-mixed surface layer on top of a poorly mixed deep layer and nutr...
متن کاملSeasonal and vertical distribution of putative ammonia-oxidizing thaumarchaeotal populations in an oligotrophic lake
The discovery of Archaea carrying an amoA gene coding for the A-subunit of ammonia monooxygenase gave a boost to studies aimed at detecting this gene under diverse conditions. Despite numerous studies describing the archaeal amoA gene abundance and richness in different habitats, the understanding of the freshwater ecology of potentially 5 archaeal ammonia-oxidizers, recently positioned in the ...
