ReAS: Recovery of Ancestral Sequences for Transposable Elements from the Unassembled Reads of a Whole Genome Shotgun
Download2005
Ye, C., Wang, J., Li, S., Li, R., Wong, G.K.S., Ye, J., Yang, H., Han, Y., Yu, J.
We describe an algorithm, ReAS, to recover ancestral sequences for transposable elements (TEs) from the unassembled reads of a whole genome shotgun. The main assumptions are that these TEs must exist at high copy numbers across the genome and must not be so old that they are no longer...

Residual tree retention ameliorates short-term effects of clear-cutting on some boreal songbirds
Download2001
Hannon, S. J., Norton, M. R., Tittler, R.
Abstract: Retention of residual trees in \"cutblocks,\" logged blocks of forest, has been proposed as a method to conserve songbirds in landscapes fragmented by clear-cut logging. We examined songbird communities in the boreal mixed-wood forest of Alberta, Canada, to investigate the effect on...

Simulated Livestock Soil Compaction, Plant Defoliation and Litter Removal Effects on Extracellular Enzyme Activity and Vegetation Across a Moisture Gradient in Southern Alberta, Canada
DownloadSpring 2020
Barszczewski, Sara Janina Bodnar
Preservation of grasslands is vital for the continuation of the numerous ecosystem goods and services (EG&S) provided by these ecosystems, including forage for livestock, nutrient cycling, carbon sequestration and habitat for flora and fauna. All EG&S in grasslands are supported by microbial...

The APETALA-2-Like Transcription Factor OsAP2-39 Controls Key Interactions between Abscisic Acid and Gibberellin in Rice
Download2010
Rothstein, Steven J., Bi, Yong-Mei, Zhu, Tong, El-kereamy, Ashraf, Beatty, Perrin H., Yaish, Mahmoud W., Good, Allen G.
The interaction between phytohormones is an important mechanism which controls growth and developmental processes in plants. Deciphering these interactions is a crucial step in helping to develop crops with enhanced yield and resistance to environmental stresses. Controlling the expression level...

The biosphere as an increasing sink for atmospheric carbon: estimates from increased nitrogen deposition
Download1993
Estimates of carbon uptake and storage based on global nitrogen deposition, C:N ratios for typical terrestrial ecosystems, and recent ecosystem-scale nutrient studies indicate that 1.0- 2.3 Gt C yr-1 of carbon storage may be stimulated by anthropogenically caused increases in nitrogen deposition...

Lepage, B. A., Currah, R. S., Stockey, R. A.
The middle Eocene Princeton chert locality in southern British Columbia, Canada, contains one of the best-preserved permineralized Tertiary floral assemblages known in North America. The quality of pres- ervation of the vascular plant and fungal remains is exquisite because anatomical and...

The potential of aspen clonal forestry in Alberta: breeding regions and estimates of genetic gain from selection
Download2012
Brouard, J.S., Hamann, A., Gylander, T., Thomas, B.R.
Background: Aspen naturally grows in large, single-species, even-aged stands that regenerate clonally after fire disturbance. This offers an opportunity for an intensive clonal forestry system that closely emulates the natural life history of the species. In this paper, we assess the potential of...

The root distribution, architecture, transpiration and root sapflow dynamics of mature trembling aspen (Populus tremuloides) growing along a hillslope
DownloadFall 2013
The objectives of this study were to explore comparative controls by atmospheric and belowground variables governing transpiration of trembling aspen (Populus tremuloides) growing along a water limited hillslope. Vertical and horizontal root distribution, intra- and inter-clonal root connections,...
