A global molecular phylogeny yields insights into the dispersal and invasion history of , a butterfly genus with remarkable dispersal abilities.
Proc Biol Sci

Department of Biological Sciences, University of Manitoba, Winnipeg, Manitoba, Canada.
The nymphalid butterfly genus has remarkable dispersal abilities. Occurring on every continent except Europe and Antarctica, are often among the only butterflies on remote oceanic islands. The biogeography of has been controversial, plagued by taxonomic disputes, small phylogenetic datasets, incomplete taxon sampling, and shared interspecific mitochondrial haplotypes.

The demographic history of a species can have a lasting impact on its contemporary population genetic structure. Northeastern Pacific (NEP) populations of the rocky shore gastropod have very little mitochondrial DNA (mtDNA) sequence diversity and show no significant population structure despite lacking dispersive planktonic larvae. A contrasting pattern of high mtDNA diversity in the northwestern Pacific (NWP) suggests that may have recently colonized the NEP from the NWP via stepping-stone colonization through the Aleutian-Commander Archipelago (ACA) following the end of the last glacial 20,000 years ago.

How health advocates and industry actors attempt to assert their authority as a strategy of influence in policymaking remains underexplored in the health governance literature. Greater exploration of the kinds of authority sources used by health actors vis-à-vis market actors and the role ideational factors may play in shaping access to these sources provides insight into advocates' efforts to exert influence in policy forums. Using the trade domain in Australia as a case study of the way in which the commercial determinants of health operate, we examined the different ways in which health, public interest and market actors assert their authority.

Faculty of Medicine, University of Ottawa, Ontario, Canada.
Objectives: A structured, reflection-based electronic portfolio program (ePortfolio), with novel faculty development initiative, involving 'shadow coaches', was shared with the newly formed Ottawa-Shanghai Joint School of Medicine (OSJSM). OSJSM is a partnership between Shanghai Jiao Tong University and the University of Ottawa. As the world's first Sino-Canadian Joint Medical School, OSJSM introduced North American undergraduate medical curriculum to China.

The goal of this study was to evaluate survival of important viral pathogens of livestock in animal feed ingredients imported daily into the United States under simulated transboundary conditions. Eleven viruses were selected based on global significance and impact to the livestock industry, including Foot and Mouth Disease Virus (FMDV), Classical Swine Fever Virus (CSFV), African Swine Fever Virus (ASFV), Influenza A Virus of Swine (IAV-S), Pseudorabies virus (PRV), Nipah Virus (NiV), Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Swine Vesicular Disease Virus (SVDV), Vesicular Stomatitis Virus (VSV), Porcine Circovirus Type 2 (PCV2) and Vesicular Exanthema of Swine Virus (VESV). Surrogate viruses with similar genetic and physical properties were used for 6 viruses.
