The genomic basis of trophic strategy in marine bacteria
Many marine bacteria have evolved to grow optimally at either high (copiotrophic) or low (oligotrophic) nutrient concentrations, enabling different species to colonize distinct trophic habitats inExpand

Cold-adapted enzymes.
By far the largest proportion of the Earth's biosphere is comprised of organisms that thrive in cold environments (psychrophiles). Their ability to proliferate in the cold is predicated on a capacityExpand

Responses to Stress and Nutrient Availability by the Marine Ultramicrobacterium Sphingomonas sp. Strain RB2256.
Sphingomonas sp. strain RB2256 was isolated from Resurrection Bay in Alaska and possibly represents the dominant bacterial species in some oligotrophic marine environments. Strain RB2256 has aExpand

Cold-adapted archaea
Many archaea are extremophiles. They thrive at high temperatures, at high pressure and in concentrated acidic environments. Nevertheless, the largest proportion and greatest diversity of archaeaExpand

The role of planktonic Flavobacteria in processing algal organic matter in coastal East Antarctica revealed using metagenomics and metaproteomics.
Heterotrophic marine bacteria play key roles in remineralizing organic matter generated from primary production. However, far more is known about which groups are dominant than about the cellularExpand

Global biogeography of SAR11 marine bacteria
The ubiquitous SAR11 bacterial clade is the most abundant type of organism in the world's oceans, but the reasons for its success are not fully elucidated. We analysed 128 surface marine metagenomes,Expand

Virophage control of antarctic algal host–virus dynamics
Viruses are abundant ubiquitous members of microbial communities and in the marine environment affect population structure and nutrient cycling by infecting and lysing primary producers. AntarcticExpand

A metagenomic assessment of winter and summer bacterioplankton from Antarctica Peninsula coastal surface waters
Antarctic surface oceans are well-studied during summer when irradiance levels are high, sea ice is melting and primary productivity is at a maximum. Coincident with this timing, the bacterioplanktonExpand

A metaproteomic assessment of winter and summer bacterioplankton from Antarctic Peninsula coastal surface waters
A metaproteomic survey of surface coastal waters near Palmer Station on the Antarctic Peninsula, West Antarctica, was performed, revealing marked differences in the functional capacity of summer andExpand

An integrative study of a meromictic lake ecosystem in Antarctica
In nature, the complexity and structure of microbial communities varies widely, ranging from a few species to thousands of species, and from highly structured to highly unstructured communities.Expand
