Kabin, Konstantin, Marchand, Richard, Lu, J. Y., Rankin, Robert, Tikhonchuk, Vladimir T.
It is shown that perpendicular gradients in shear Alfvén wave (SAW) dispersion regulate the localization of wave power on nightside geomagnetic L-shells where narrow Field Line Resonances (FLRs) form. We estimate the timescale for this process, ω0tc = 1/equation image, and demonstrate that it is...

Transcriptional regulation of lipid metabolism: A key determinant of pancreatic ß-cell function
Download2005
Fatehi-Hassanabad, Zahra, Chan, Catherine B.
Background Optimal pancreatic β-cell function is essential for the regulation of glucose homeostasis in both humans and animals and its impairment leads to the development of diabetes. Type 2 diabetes is a polygenic disease aggravated by environmental factors such as low physical activity or a...

Tropical forest restoration within Galapagos National Park: application of a state-transition model
Download2005
Wilkinson, S.R., Schmeigelow, F.K.A., Naeth, M.A.
Current theory on non-equilibrium communities, thresholds of irreversibility, and ecological resilience suggests the goal of ecological restoration of degraded communities is not to achieve one target, but to reestablish the temporal and spatial diversity inherent in natural ecosystems. Few...

Understory responses to mechanical restoration and drought within Montane forests of British Columbia
Download2005
Bork, E. W., Newman, R. F., Page, H. N.
Pre- and post-thinning relationships between forest overstorey and understorey characteristics at sites in both the Interior Douglas-fir (IDF) and Ponderosa Pine (PP) biogeoclimatic zones in the East Kootenay region of southeast British Columbia were investigated to quantify understorey responses...

Fagan, William F., Lewis, Mark A., Neubert, Michael G., Aumann, Craig, Apple, Jennifer L., Bishop, John G.
Here we study the spatial dynamics of a coinvading consumer‐resource pair. We present a theoretical treatment with extensive empirical data from a long‐studied field system in which native herbivorous insects attack a population of lupine plants recolonizing a primary successional landscape...

Which resources should be used to identify RCT/CCTs for systematic reviews: a systematic review.
Download2005
Cramer, K., Hartling, L., Wiebe, N., Klassen, T. P., Crumley, E. T.
Background Systematic reviewers seek to comprehensively search for relevant studies and summarize these to present the most valid estimate of intervention effectiveness. The more resources searched, the higher the yield, and thus time and costs required to conduct a systematic review. While there...

Wolves Influence Elk Movements: Behavior Shapes a Trophic Cascade in Yellowstone National Park
Download2005
Fortin, D., Beyer, H. L., Smith, D. W., Boyce, M. S., Mao, J. S., Duchesne, T.
A trophic cascade recently has been reported among wolves, elk, and aspen on the northern winter range of Yellowstone National Park, Wyoming, USA, but the mechanisms of indirect interactions within this food chain have yet to be established. We investigated whether the observed trophic cascade...
