Evolution on a volcanic conveyor belt: using phylogeographic reconstructions and K–Ar‐based ages of the Hawaiian Islands to estimate molecular evolutionary rates
The Hawaiian Islands form as the Pacific Plate moves over a ‘hot spot’ in the earth’s mantle where magma extrudes through the crust to build huge shield volcanos. The islands subside and erode as theExpand
Whole genome-based population biology and epidemiological surveillance of Listeria monocytogenes
TLDR
This work demonstrates the urgent need to monitor Lm strains at the global level and provides the unified approach needed for global harmonization of Lm genome-based typing and population biology. Expand
Multistate outbreak of listeriosis associated with cantaloupe.
TLDR
Raw produce, including cantaloupe, can serve as a vehicle for listeriosis, and this outbreak highlights the importance of preventing produce contamination within farm and processing environments. Expand
MITOCHONDRIAL-DNA VARIATION AND EVOLUTIONARY RELATIONSHIPS IN THE AMAKIHI COMPLEX
TLDR
Genetic distances and the pattern of relationships among amakihi taxa indicate that species status for H. v. chloris and H. stejnegeri may be warranted, and the relationships within the chloris-stejnegersi-parvus clade generally are consistent with the previously proposed model of double invasion.

Identification of Vibrio Isolates by a Multiplex PCR Assay and rpoB Sequence Determination
TLDR
The PCR assay provides a simple, rapid, and reliable tool for identification of the major Vibrio pathogens in clinical samples, and rpoB sequencing provides an additional identification tool for other species in the genus Vibri. Expand
Comparative Genomics of Vibrio cholerae from Haiti, Asia, and Africa
TLDR
A strain from Haiti shares genetic ancestry with those from Asia and Africa, and is thought to be the first of its kind in the world. Expand
Cryptic genetic variation and paraphyly in ravens
TLDR
The findings suggest that the common raven may have formerly consisted of two allopatric groups that may be in the process of remerging, and is likely to harbour cryptic genetic variation. Expand
Evolutionary Dynamics of Vibrio cholerae O1 following a Single-Source Introduction to Haiti
TLDR
Intensive mutational processes can account for virtually all of the observed genetic polymorphism, with no demonstrable contribution from horizontal gene transfer (HGT), and no evidence that environmental strains have played a role in the evolution of the outbreak strain. Expand
Genomic Comparison of Escherichia coli O104:H4 Isolates from 2009 and 2011 Reveals Plasmid, and Prophage Heterogeneity, Including Shiga Toxin Encoding Phage stx2
TLDR
Comparative genome analysis indicates that, while the Georgian strains are the nearest neighbors to the 2011 outbreak isolates sequenced to date, structural and nucleotide-level differences are evident in the Stx2 phage genomes, the mer/tet antibiotic resistance island, and in the prophage and plasmid profiles of the strains; and multiphenotype analysis showed that 2009EL–2071 possessed higher resistance to polymyxin and membrane-disrupting agents.

TLDR
Primers are reported that can be used to enzymatically amplify and sequence the entire control region of mitochondria1 DNA in at least two passerine families, and partial segments in additional oscine families. Expand
