Pelagic microbes have adopted distinct strategies to inhabit the pelagial of lakes and
oceans and can be broadly categorized in two groups: free‐living, specialized oligotrophs …

As revealed by genome sequencing, the biology of prokaryotes with reduced genomes is
strikingly diverse. These include free-living prokaryotes with∼ 800 genes as well as …

Although many source waterbodies face nitrogen pollution problems, the lack of organic
electron donors causes difficulties when aerobic denitrifying bacteria are used to treat micro …

Background Genomes of bacteria and archaea (collectively, prokaryotes) appear to exist in
incessant flux, expanding via horizontal gene transfer and gene duplication, and contracting …

Permafrost thawing leads to the formation of thermokarst ponds that potentially emit CO2
and CH4 to the atmosphere. In the Nunavik subarctic region (northern Québec, Canada) …

Transplantation experiments and genome comparisons were used to determine if lineages
of planktonic Polynucleobacter almost indistinguishable by their 16S ribosomal RNA (rRNA) …

Endosymbioses between bacteria and eukaryotes are enormously important in ecology and
evolution, and as such are intensely studied. Despite this, the range of investigated hosts is …

Endosymbiosis plays an important role in ecology and evolution, but fundamental aspects of
the origin of intracellular symbionts remain unclear. The extreme age of many symbiotic …

Taxonomy is the science of defining and naming groups of biological organisms based on
shared characteristics and, more recently, on evolutionary relationships. With the birth of …

The thecate amoeba Paulinella is a valuable model for understanding plastid
organellogenesis because this lineage has independently gained plastids (termed …
