Harden, J.W., Payne, N., Friedli, H.R., Radke, L.F., Crock, J., Flannigan, M.D., Turetsky, M.R.
With climate change rapidly affecting northern forests and wetlands, mercury reserves once protected in cold, wet soils are being exposed to burning, likely triggering large releases of mercury to the atmosphere. We quantify organic soil mercury stocks and burn areas across western, boreal Canada...

The role of historical fire disturbance in the carbon dynamics of the pan-boreal region: A process-based analysis
Download2007
Apps, M., Zhuang, Q., Burnside, T.J., Shvidenko, A., Flannigan, M., McAllister, J., Wirth, C., Clein, J.S., Balshi, M.S., Kurz, W.A., Kicklighter, D.W., Harden, J., McGuire, A.D., Kasischke, E., Melillo, J.
Wildfire is a common occurrence in ecosystems of northern high latitudes, and changes in the fire regime of this region have consequences for carbon feedbacks to the climate system. To improve our understanding of how wildfire influences carbon dynamics of this region, we used the process-based...

Structural and Biochemical Changes in Loblolly Pine (Pinus taeda L.) Seeds During Germination and Early-Seedling Growth. I. Storage Protein Reserves
Download1997
Abstract: Quantitative and qualitative changes in the storage proteins of loblolly pine (Pinus taeda L.) seeds were followed during germination and early-seedling growth and were correlated with light-microscopic observations. In both the megagametophyte and the embryo, the cells of tissues from...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...

Welz, M., Faulkner, S.G., Tonn, W.M., Schmitt, D.R.
Industrial development, including geophysical exploration and mining, has increased use of explosives in and near fish habitat. To protect fish and their incubating eggs, Canadian blasting guidelines contain maximum allowable limits for overpressure and peak particle velocity (PPV). Although many...
