Schneider, Richard R, Bayne, Erin M
Ecosystem distributions are expected to shift as a result of global warming, raising concerns about the long-term utility of reserve systems based on coarse-filter ecosystem representation. We tested the extent to which proportional ecosystem representation targets would be maintained under a...

Short-term plant community responses to warming and defoliation in a northern temperate grassland
Download2011
Cahill, Jr. J. F., Bork, E. W., Chang, S. X., Deutsch, E. S.
Abstract: Little is known about the short-term impacts of warming on native plant community dynamics in the northern Canadian prairies. This study examined the immediate effects of elevated temperature and defoliation on plant community diversity, composition, and biomass within a native rough...

Simulated impacts of relative climate change and river discharge regulation on sea ice and oceanographic conditions in the Hudson Bay Complex
Download2021-01-01
Lukovich, Jennifer V., Jafarikhasragh, Shabnam, Myers, Paul G., Ridenour, Natasha A., de la Guardia, Laura Castro, Hu, Xianmin, Grivault, Nathan, Marson, Juliana, Pennelly, Clark, Stroeve, Julienne C., Sydor, Kevin, Wong, Karen, Stadnyk, T. A., Barber, D. G.
In this analysis, we examine relative contributions from climate change and river discharge regulation to changes in marine conditions in the Hudson Bay Complex using a subset of five atmospheric forcing scenarios from the Coupled Model Intercomparison Project Phase 5 (CMIP5), river discharge...

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...

Temperature-dependent Allee effects in a stage-structured model for Bythotrephes establishment
Download2011-01-01
Young, J. D., Yan, N. D., Lewis, Mark A., Wittmann, M. J.
Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

Temporal variability in area burned for the Province of Ontario, Canada during the past 200 years inferred from tree-rings
Download2006
Tardif, J., Flannigan, M.D., Girardin, M.P.
Area burned variability in the province of Ontario, Canada, was inferred from 25 tree ring width chronologies covering A. D. 1781-1982 and distributed largely across the Boreal Shield. The area burned estimates account for 39.5% of the variance in the actual area burned recorded from 1917 to 1981...

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...
