On the importance of the choice of wind stress forcing to the modeling of the Mediterranean Sea circulation
Download1998
Myers, Paul G., Josey, Simon, Haines, Keith
A 1/4° degree ocean general circulation model is used to examine the role that four different wind stress climatologies play on the circulation of the Mediterranean. The wind stress climatologies examined are those derived from numerical weather prediction models (National Meteorological Center...

Veit, R. R., Banks, J. E., Holmes, E. E., Lewis, M. A.
Most of the fundamental elements of ecology, ranging from individual behavior to species abundance, diversity, and population dynamics, exhibit spatial variation. Partial differential equation models provide a means of melding organism movement with population processes and have been used...

Background. It has been suggested that the routine use of statins preoperatively would reduce the risk of postoperative infection. We conducted this study to explore whether preoperative statin use was associated with infection after cardiac surgery (recipients of which have a higher-than-average...

Nisbet, Roger, Anderson, Kurt E., McCauley, Edward, Lewis, Mark A.
Much ecological research involves identifying connections between abiotic forcing and population densities or distributions. We present theory that describes this relationship for populations in media with strong unidirectional flow (e.g., aquatic organisms in streams and rivers). Typically,...

Rough fescue (Festuca campestris Rydb.) is an ecologically and economically important native plant species within grasslands of southwest Alberta. This is also a region where wildfires have become prevalent over the last decade. While the risk of long-term damage from fire may be determined by...

Slaughter, S., Bostrom, A.M., Cummings, G.G., Morgan, D.G., Estabrooks, C.A., Norton, P.G., Squires, J.E.
Background: Defining what constitutes a resident care unit in nursing home research is both a conceptual and practical challenge. The aim of this paper is to provide evidence in support of a definition of care unit in nursing homes by demonstrating: (1) its feasibility for use in data collection,...

The genetic signature of rapid range expansions: How dispersal, growth and invasion speed impact heterozygosity and allele surfing
Download2014-01-01
Lewis, Mark A. , Coltman, David W. , Goodsman, Devin W., Cooke, Barry
As researchers collect spatiotemporal population and genetic data in tandem, models that connect demography and dispersal to genetics are increasingly relevant. The dominant spatiotemporal model of invasion genetics is the stepping-stone model which represents a gradual range expansion in which...

Goodsman, Devin W., Lewis, Mark A.
Dispersal can push population density below strong Allee thresholds ensuring the demise of small founding populations. As a result, for isolated populations of dispersing organisms, the minimum founding population size that enables establishment can be quite different from the Allee threshold. 2....

The relationship between body mass index, treatment, and mortality in patients with established coronary artery disease:a report from APPROACH.
Download2009
Padwal, R. A., Sharma, A., Kalanta-Zadeh, K., Oreopoulos, A., Norris, C.M., McAlister, F. A., Ezekowitz, J., Fonarow, G.C.
Our objective was to examine the association between body mass index (BMI) and survival according to the type of treatment in individuals with established coronary artery disease (CAD). Methods and results: Patients with CAD were identified in the Alberta Provincial Project for Outcome Assessment...

Tracing an Invasion : Phylogeography of Cactoblastis cactorum ( Lepidoptera : Pyralidae ) in the United States Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Simonsen, T. J., Brown, R. L.
Abstract: The adventive cactus moth Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), a widely used biological control agent for Opuntia Mill. cacti, was detected in Florida in 1989. Since then, it has spread along the Atlantic and Gulf Coasts of southeastern United States, threatening...
