Improving the accuracy of protein secondary structure prediction using structural alignment
Download2006
Gallin, W.J., Wishart, D.S., Montgomerie, S., Sundararaj, S.
Background: The accuracy of protein secondary structure prediction has steadily improved over the past 30 years. Now many secondary structure prediction methods routinely achieve an accuracy (Q3) of about 75%. We believe this accuracy could be further improved by including structure (as opposed...

Fossil seedlings and seeds of an extinct Cercidiphyllum-like plant occur in the Paskapoo Formation (Late Paleocene) at Joffre Bridge near Red Deer, Alberta. Cotyledon and early seedling leaf stages are preserved in growth position. Morphological details of seedlings and seeds support a close...

In situ fossil seedlings of a Metasequoia-like taxodiaceous conifer from Paleocene river floodplain deposits of central Alberta, Canada
Download1999
Stockey, R.A., Faldner, A.B., Rothwell, G.W.
Fossil seeds and seedlings of a Metasequoia-like taxodiaceous conifer occur in Paleocene deposits at the Munce’s Hill and Gao Mine localities of central Alberta, Canada. Compression/impression specimens are preserved in upright growth positions among seedlings of the cercidiphyllaceous dicot...

In vivo and in vitro evaluation of Beauveria bassiana pathogenicity for western flower thrips, Frankliniella occidentalis [MSc Dissertation]
Download2007
Western flower thrips, Frankliniella occidentalis, are major pests in greenhouses. The fungus Beauveria bassiana is a safer alternative to use of chemical insecticides against this insect; and evaluating isolates for high virulence has usually involved in vivo studies. My approach examines in...

Independent evolution of leaf and root traits within and among temperate grassland plant communities
Download2011-01-01
In this study, we used data from temperate grassland plant communities in Alberta, Canada to test two longstanding hypotheses in ecology: 1) that there has been correlated evolution of the leaves and roots of plants due to selection for an integrated whole-plant resource uptake strategy, and 2)...

In barley (Hordeum vulgare L.), alcohol dehydrogenase (ADH) and lactate dehydrogenase (LDH) are induced by anaerobiosis in both aleurone layers and roots. Under aerobic conditions, developing seeds of cv Himalaya accumulate ADH activity, which survives seed drying and rehydration. This activity...

Induction of microsomal membrane proteins in roots of an aluminum-resistant cultivar of Triticum aestivum L. under conditions of aluminum stress
Download1994
Basu, U., Basu, A., Taylor, G. J.
Three-day-old seedlings of an Al-sensitive (Neepawa) and an Al-resistant (PT741) cultivar of Triticum aestivum were subjected to Al concentrations ranging from a to 100 mu M for 72 h. At 25 mu M Al, growth of roots was inhibited by 57% in the Al-sensitive cultivar, whereas root growth in the...

Induction of Vacuolar ATPase and Mitochondrial ATP Synthase by Aluminum in an Aluminum-Resistant Cultivar of Wheat
Download2001
Hamilton, C. A., Taylor, G. J., Good, A. G.
Two 51-kD aluminum (Al)-induced proteins (RMP51, root membrane proteins of 51 kD) were recently discovered in an aluminum-resistant cultivar of wheat (Triticum aestivum) cv PT741 (Basu et al., 1994a). These proteins segregate with the aluminum resistance phenotype in a segregating population...

1999
Two instances of infanticide and cannibalism in polar bears (Ursus maritimus) were observed in SE Svalbard, at Hopen Island. In the first, an adult male killed three young cubs at a den site and consumed one of them. In the second, an adult male actively pursued, killed, and consumed a dependent...

Influence of subhumid climate and water table depth on groundwater recharge in shallow outwash aquifers
Download2008
Smerdon, B.D., Mendoza, C.A., Devito, K.J.
[1] Hypothetical one-dimensional models of unsaturated flow were used to estimate the probability of groundwater recharge to shallow, glacial outwash aquifers. Simulations were supported by field data, previous three-dimensional modeling, and cross-sectional models of water table response to...
