Trophic Relations of the Red-Necked Grebe on Lakes in the Western Boreal Forest: A Stable-Isotope Analysis.
Download2004
Tonn, W. M., Klatt, P. H., Paszkowski, C. A., Gingras, B. A., Wilcox, K.
We compared trophic ecology of grebes inferred from stable-isotope analysis to that from gut contents, and compared isotopic ratios of Red-necked Grebes (Podiceps grisegena) from lakes differing in their food webs. Analyses of different grebe tissues (egg yolk and albumen, pectoral and leg...

Tumour-stromal interactions: Integrins and cell adhesions as modulators of mammary cell survival and transformation
Download2001
Chrenek, Micah A., Weaver, Valerie M., Wong, Paul
Stromal–epithelial interactions modulate mammary epithelial cell (MEC) growth and apoptosis by influencing cell adhesion and tissue organization. Perturbations in the mammary stroma and cell adhesion characterize breast tumors and underlie the altered tissue organization, disrupted tissue...

Two New Species of Pseudogymnoascus with Geomyces Anamorphs and Their Phylogenetic Relationship with Gymnostellatospora
Download2006
Rice, Adrianne V., Currah, Randolph S.
Two new psychrophilic Pseudogymnoascus species with Geomyces anamorphs are described from a Sphagnum bog in Alberta, Canada. Pseudogymnoascus appendiculatus has long, branched, orange appendages and smooth, fusoid to ellipsoidal ascospores with a faint longitudinal rim. Pseudogymnoascus...

Ultraviolet-ozone treatment reduces levels of disease-associated prion protein and prion infectivity
Download2009
Gilbert, P., Pedersen, J., McKenzie, D., Johnson, C.J., Aiken, J.M.
Background: Transmissible spongiform encephalopathies (TSEs) are a group of fatal neurodegenerative diseases caused by novel infectious agents referred to as prions. Prions appear to be composed primarily, if not exclusively, of a misfolded isoform of the cellular prion protein. TSE infectivity...

Sponges are important but often-neglected organisms. The absence of classical animal traits (nerves, digestive tract, and muscles) makes sponges challenging for non-specialists to work with and has delayed getting high quality genomic data compared to other invertebrates. Yet analyses of sponge...

Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, Genetics
Download2013-01-01
Hamelin, Richard C., Tsui, Clement K.M., Bohlmann, Jörg, DiGuistini, Scott, Dhillon, Braham, Feau, Nicolas, Wang, Ye
Sexual reproduction in fungi is regulated by the mating-type (MAT) locus where recombination is suppressed. We investigated the evolution of MAT loci in eight fungal species belonging to Grosmannia and Ophiostoma (Sordariomycetes, Ascomycota) that include conifer pathogens and beetle symbionts....

Unique and Overlapping Expression Patterns among Members of Photosynthesis-Associated Nuclear Gene Families in Arabidopsis
Download2008
Sawchuck, M. G., Scarpella, E., Head, P., Donner, T. J.
Light provides crucial positional information in plant development, and the morphogenetic processes that are orchestrated by light signals are triggered by changes of gene expression in response to variations in light parameters. Control of expression of members of the RbcS and Lhc families of...

Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...

Unveiling trade-offs in resource selection of migratory caribou using a mechanistic movement model of availability
Download2015-01-01
Guillaume, Bastille-Rousseau, Jonathan R., Potts, James A., Schaefer, Mark A., Lewis, Hance E., Ellington, Nathaniel D., Rayl, Shane P., Mahoney, Dennis L., Murray
Habitat selection is a multi-level, hierarchical process that should be a key component in the balance between food acquisition and predation risk avoidance (food–predation trade-off). However, to date, studies have not fully elucidated how fine- and broad-scale habitat decisions by individual...
