BACKGROUND Although polychaetes are one of the dominant taxa in marine communities, their distributions and taxonomic diversity are poorly understood. Recent studies have shown that many species thought to have broad distributions are actually a complex of allied species. In Canada, 12% of polychaete species are thought to occur in Atlantic, Arctic, and(More)
Theoretical development in the field of community ecology needs ground proofing with empirical tests. In addition, these tests need to be continuously updated. Cottenie (2005) linked observed metacommunities to theoretical models based on whether environmental and/or spatial effects in the observed metacommunity significantly explain community structure.(More)
The last decade has seen an increase in the frequency and breadth of application of molecular tools, many of which are beginning to shed light on long-standing questions in biogeography and evolutionary history of marine fauna. We explore new developments with respect to Arctic marine invertebrates, focusing on molecular taxonomy and phylogeography—two(More)
This paper investigated the supramolecular properties and accessibility of fibres regenerated from cotton-based waste garments and compared to typical lyocell fibres. The supramolecular and accessibility properties of the cotton-based waste garments fibres regenerated from three sources (waste denim garments, easy care finished cotton fabrics and a blend of(More)
As changes to Canada’s marine biodiversity loom and the tools for assessing biodiversity advance, it becomes increasingly important to have baseline information about a region’s species so that future comparisons can be made. The polychaetes represent a conspicuous component of benthic communities in Canadian marine waters, yet information on species(More)
Species diversity influences the productivity and stability of plant communities, but its effect on the evolution of species within those communities is poorly understood. In this study, we tested whether species diversity and soil type influence selection on physiology in switchgrass (Panicum virgatum). Plants were grown in 0.33–0.55 ha plots in eight(More)

A simple reduction/labelling/extraction protocol has been developed to fractionate cortical matrix proteins from filament proteins in wool. Through differential labelling of cysteine residues their relative accessibility in the wool fibre has been investigated. This has allowed the preliminary development of a map of the chemical functionality that is(More)
