Stratford, Kevin, Williams, Richard G., Myers, Paul G.
The role of the thermohaline circulation in controlling export production, oxygenation of deep waters, and hence possible sapropel formation in the eastern Mediterranean is examined using a simple nutrient-cycling model. The model is driven by velocity fields from a general circulation model and...

Nitrogen (N) is the most important factor limiting crop productivity worldwide. The ability of plants to acquire N from applied fertilizers is one of the critical steps limiting the efficient use of nitrogen. To improve N use efficiency, genetically modified plants that overexpress alanine...

The overall objective of this study was to measure the major nitrogen pools and fluxes in nutrient- and peat-rich, vegetated marshes and fens surrounding shallow ponds in the Western Boreal Plain (WBP) of Canada. Within the same peatland-pond complex, marshes and fens did not differ from each...

Neural networks modelling of stream nitrogen using remote sensing information: model development and application
DownloadFall 2009
In remotely located forest watersheds, monitoring nitrogen (N) in streams often is not feasible because of the high costs and site inaccessibility. Therefore, modelling tools that can predict N in unmonitored watersheds are urgently needed to support management decisions for these watersheds....

Planktonic responses to nitrogen and phosphorus deposition - a natural alpine pond experiment
DownloadFall 2010
Several lines of evidence suggest small alpine lakes and ponds are sensitive to nitrogen deposition. Paleolimnological studies, nutrient bioassays, and mesocosm experiments show the positive effects of nitrogen on aquatic alpine primary producers. In particular, alpine pond ecosystems have been...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...

The sucrose-nonfermenting-1 related kinase 1 (SnRK1) protein complex is a heterotrimeric serine/threonine protein kinase complex conserved in eukaryotes that acts as a regulator of carbon metabolism and energy homeostasis. The objective of this study was to determine if the SnRK1 protein complex...

Large polycyclic aromatic nitrogen containing asphaltene model compounds, with molecular weights from 535 to 702 g/mol, were catalytically hydrogenated and hydrodenitrogenated in the presence of a commercial NiMo/γAl2O3 catalyst in a stainless steel batch reactor at 370 °C and 17.9 MPa total...
