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

Diversity and association of psychrophilic bacteria in Antarctic sea ice.
The bacterial populations associated with sea ice sampled from Antarctic coastal areas were investigated by use of a phenotypic approach and a phylogenetic approach based on genes encoding 16S rRNAExpand

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 molecular phylogenetic survey of sea-ice microbial communities (SIMCO).
16S rDNA clone library analysis was used to identify bacterial biodiversity in a variety of sea-ice microbial communities (SIMCO). DNA was extracted from seven Antarctic sea-ice samples and oneExpand

Marine bacterial microdiversity as revealed by internal transcribed spacer analysis
A growing body of evidence suggests analysis of 16S rRNA gene sequences provides only a conservative estimate of the actual genetic diversity existing within microbial communities. We examined theExpand

High level of intergenera gene exchange shapes the evolution of haloarchaea in an isolated Antarctic lake
Significance Horizontal gene exchange across species boundaries is considered infrequent relative to vertical inheritance that maintains species coherence. However, haloarchaea living in hypersalineExpand

Microbial diversity at Mitchell Peninsula, Eastern Antarctica: a potential biodiversity “hotspot”
Abstract Mitchell Peninsula is located towards the East of the Windmill Islands in eastern Antarctica. It is an ice-free polar desert, and knowledge of its soil microbial taxonomic composition isExpand

Evidence for tropical endemicity in the Deltaproteobacteria Marine Group B/SAR324 bacterioplankton clade
The fine-scale phylogeny of the deeply branching Deltaproteobacteria Marine Group B/SAR324 (MGB/SAR324) bacterioplankton clade was analyzed using partial 16S rRNA gene sequence and internalExpand

The marine mammal microbiome: current knowledge and future directions
Marine mammals are globally significant because of their sensitivity to environmental change and threatened status, often serving as ‘ecosystem sentinels’. Disease is a major cause of marinemammalExpand

Capturing Greater 16S rRNA Gene Sequence Diversity within the Domain Bacteria
ABSTRACT A large proportion of “universal” 16S PCR primers lack sequence homology to many of the “candidate” divisions, severely limiting bacterial diversity assessments. We designed a primer setExpand
