Populations of animals are composed of individuals that differ in ecologically relevant behaviors. Building evidence also suggests that individuals occupy different social niches. Here, in a mark-recapture experiment, we show evidence of an interacting effect of behavior and social niche on survival in the wild: bold individuals had higher survival if they were initially captured in groups while shy, inactive individuals had higher survival if they were initially captured when alone.

Methodology/principal Findings: In order to improve our understanding of this lineage, we have completely sequenced the genomes of two members of this order, Methanocorpusculum labreanum Z and Methanoculleus marisnigri JR1, and compared them with the genome of a third, Methanospirillum hungatei JF-1.
Background: Staphylothermus marinus is an anaerobic, sulfur-reducing peptide fermenter of the archaeal phylum Crenarchaeota. It is the third heterotrophic, obligate sulfur reducing crenarchaeote to be sequenced and provides an opportunity for comparative analysis of the three genomes.

In this commentary, we provide a personal overview of the conceptual history of microbiology and molecular biology over the course of the last hundred years, emphasizing the relationship of these fields to the problem of evolution. We argue that despite their apparent success, all three reached an impasse that arose from the influence of dogmatic or overly narrow perspectives. Finally, we describe how recent developments in microbiology are realizing Beijerinck's vision of a field that is fully integrated with molecular biology, microbial ecology, thereby challenging and extending current thinking in evolution.
