The role of water channel proteins in facilitating recovery of leaf hydraulic concutance from water stress in Populus trichocarpa
Download2014
Gas exchange is constrained by the whole-plant hydraulic conductance (Kplant). Leaves account for an important fraction of Kplant and may therefore represent a major determinant of plant productivity. Leaf hydraulic conductance (Kleaf) decreases with increasing water stress, which is due to xylem...

The soil microbial community and grain micronutrient concentration of historical and modern hard red spring wheat cultivars grown organically and conventionally in the Black soil zone of the Canadian prairies
Download2011
Nelson, A. G., Spaner, D. M., Frick, B., Clapperton, M.J., Hucl, P. J., Thavarajah, D., Quideau, S. A.
Abstract: Micronutrient deficiencies in the diet of many people are common and wheat is a staple food crop, providing a carbohydrate and micronutrient source to a large percentage of the world’s population. We conducted a field study to compare five Canadian red spring wheat cultivars (released...

The standard centrifuge method accurately measures vulnerability curves of longvesselled olive stems
Download2015
Venturas, M.D., Sperry, J.S., Hacke, U.G., Pratt, R.B. , Jacobsen, J.S., MacKinnon, E.D.
The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested...

The Three Gorges Dam in China is the largest dam ever built. Its impacts on the biodiversity and ecological processes in the region are causing concern to ecologists worldwide. The dam and associated environmental alterations may result in a number of regional changes in terrestrial and aquatic...

Toward conservation of Canada's boreal forest avifauna: Design and application of ecological models at continental extents
Download2010
Cumming, S. G., Bayne, E., Schmiegelow, F. K. A., Fontaine, T., Song, S. J., Lefevre, K.
Abstract: Human development is increasing pressure on North America's mainly intact boreal forest. We outline the need for a comprehensive synthesis of existing data and for effective scientific tools to support conservation of this biome and of the birds that depend on it. To illustrate how...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...

Traditional kefir reduces weight gain and improves plasma and liver lipid profiles more successfully than a commercial equivalent in a mouse model of obesity
Download2018-07-01
Bourrie, Benjamin C.T., Cotter, Paul D., Willing, Ben P.
Kefir, a fermented milk beverage, has shown promise in alleviating obesity and associated metabolic dysfunction. However, microbial characteristics are variable among traditional kefirs, and commercial kefirs drastically differ from traditional kefir. This study investigated the ability of four...

Multi-scale resource selection modeling is used to identify factors that limit species distributions across scales of space and time. This multi-scale nature of habitat suitability complicates the translation of inferences to single, spatial depictions of habitat required for conservation of...

Trees Wanted - dead or alive! Host selection and population dynamics in tree-killing bark beetles
Download2011
Erbilgin, N., Gregoire, J. C., Gilbert, M., Kausrud, K. L., Skarpaas, O., Stenseth, N. C., Okland, B.
Abstract: Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing...
