Fall 2013
Species invasions are increasing worldwide and are impacting populations, communities, and ecosystems. Non-native species that are ecosystem engineers, such as earthworms, may be particularly likely to have large impacts due to their ability to modify both biological and physical characteristics...

All species’ ranges are the result of successful past invasions. Thus, models of species’ invasions and their failure can provide insight into the formation of a species’ geographic range. Here, we study the properties of invasion models when a species cannot persist below a critical population...

Predictions for climate change include movement of temperature isoclines up to 1000 meters per year, and this is supported by recent empirical studies. This paper considers effects of a rapidly changing environment on competitive outcomes between species. The model is formulated as a system of...

Deciphering the molecular mechanisms underlying the pathobiology of esophageal squamous cell carcinoma
DownloadFall 2015
Esophageal squamous cell carcinoma (ESCC) is one of the most lethal cancers worldwide, largely due to a high frequency of tumor invasion/metastasis, chemoresistance and recurrence. In this study, we explored from different perspectives the molecular mechanisms behind these aggressive features of...

McCauley, E., Lewis, Mark A., Lutscher, F.
The question how aquatic populations persist in rivers when individuals are constantly lost due to downstream drift has been termed the “drift paradox.” Recent modeling approaches have revealed diffusion-mediated persistence as a solution. We study logistically growing populations with and...

Effects of Resistance Training Frequency on Physical Functioning and Quality of Life in Prostate Cancer Survivors: A Pilot Randomized Controlled Trial
DownloadSpring 2015
Background: Resistance training (RT) improves physical functioning and quality of life in prostate cancer survivors but the optimal frequency of RT is unknown. Methods: A pilot randomized controlled trial was conducted to estimate the potential effects of 12 weeks of supervised RT for 3 days/week...

Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...

Mechanisms regulating Poa pratensis L. and Festuca campestris Rybd. within the foothills fescue grasslands of southern Alberta
DownloadFall 2011
Invasion of non-native species such as Poa pratensis L. has become a serious threat to the conservation of bunch grass communities including foothills fescue grasslands in Alberta, Canada. Conservation efforts are currently limited by a poor understanding of the ecological mechanisms responsible...
