Managing the cumulative impacts of land uses in the Western Canadian Sedimentary Basin: A modeling approach.
Download2003
Wasel, S., Schneider, R., Boutin, S., Stelfox, J.
This case study from northeastern Alberta, Canada, demonstrates a fundamentally different approach to forest management in which stakeholders balance conservation and economic objectives by weighing current management options from the point of view of their long-term effects on the forest....

Manipulation of host food availability and use of multiple exposures to assess the crowding effect on Hymenolepis diminuta in Tribolium confusum
Download2008
Walsh, J.G., Wong, Y.C., Shostak, A.W.
We studied the ‘crowding effect’ in Tribolium confusum infected with Hymenolepis diminuta. Manipulations included age and number of parasites, and diet, sex, age and number of exposures of hosts. Volume per parasite was unaffected until an intensity of at least 5–10 parasites per host, then...

Mannitol at clinical concentrations activates multiple signaling pathways and induces apoptosis in endothelial cells
Download1998
Vandorpe, D.H., Izumo, S., Malek, A.M., Goss, G.G., Jiang, L., Alper, S.L.
Background and Purpose—Hyperosmotic mannitol therapy is widely used in the clinical setting for acute and subacute reduction in brain edema, to decrease muscle damage in compartment syndrome, and to improve renal perfusion. Though beneficial rheological effects commonly are attributed to...

Sexual reproduction and dispersal are often coupled in organisms mixing sexual and asexual reproduction, such as fungi. The aim of this study is to evaluate the impact of mate limitation on the spreading speed of fungal plant parasites. Starting from a simple model with two coupled partial...

Organisms are constantly making tradeoffs. These tradeoffs may be behavioural (e.g., whether to focus on foraging or predator avoidance) or physiological (e.g., whether to allocate energy to reproduction or growth). Similarly, wildlife and fisheries managers must make tradeoffs while striving for...

Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). I. Differential pH Induced by Winter Cultivars in Nutrient Solutions.
Download1985
Twenty winter cultivars of Triticum aestivom L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-') for 14 days. Exposure to s increased root growth of the most tolerant cultivar, while both root and shoot growth were depressed in all other cultivars. On the...

Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). II. Differential pH Induced by Spring Cultivars in Nutrient Solutions.
Download1985
Twenty spring cultivars of Traticum aestivum L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-l) for 14 days. Root growth and shoot growth were depressed in all cultivars grown with A1; however, symptoms of A1 toxicity were most evident on roots. Based on...

Wishart, D.S., Psychogios, N., Young, N., Xia, J.
Metabolomics is a newly emerging field of ‘omics’ research that is concerned with characterizing large numbers of metabolites using NMR, chromatography and mass spectrometry. It is frequently used in biomarker identification and the metabolic profiling of cells, tissues or organisms. The data...

MetaboMiner – semi-automated identification of metabolites from 2D NMR spectra of complex biofluids
Download2008
Tang, P., Wishart, D.S., Xia, J., Bjorndahl, T.C.
Background One-dimensional (1D) 1H nuclear magnetic resonance (NMR) spectroscopy is widely used in metabolomic studies involving biofluids and tissue extracts. There are several software packages that support compound identification and quantification via 1D 1H NMR by spectral fitting...
