(Association of Universities and Colleges of CanadaAssociation of Universities and Colleges of Canada, 2005-11)Juggling a demanding academic career with family responsibilities – sound familiar? I nearly called it quits. Instead, I called a coach -
Determining an appropriate fire frequency for restoration and maintenance of oak savannas in Pinery Provincial Park.
(Society for Ecological Restoration, 2004-08)Oak Savanna habitat is globally rare. Prescribed burning is currently a widely-adopted management approach for restoring and maintaining these communities. We examined patterns of habitat recovery in the largest existing ... -
Determining appropriate fire frequencies for oak savannas in two Ontario Provincial Parks
(Heritage Resources Centre, University of Waterloo, 2004)Prescribed burning is a popular management tool in many prairie and savanna restorations. In Ontario's globally rare oak savanna plant communities it is viewed as a means of restoring historic disturbance regimes essential ... -
The Dimerization Interface in VraR is Essential to Induction of the Cell Wall Stress Response in Staphylococcus aureus: A potential Druggable Target
(BMC, 2019)Background Staphylococcus aureus remains a medical challenge in the treatment of bacterial infections. It has acquired resistance to commonly used antibiotics, and to those considered to be the last weapons in treating ... -
The Distribution and Abundance of Fire-scarred Trees in Pinery Provincial Park, Ontario, Canada
(Heritage Resources Center, University of Waterloo, 2006)Pinery Provincial Park contains one of the largest remaining tracts of globally rare oak (Quercus) savanna habitat. A prescribed burn plan has reintroduced fire for conservation management. We asked how closely the burn ... -
DOES CONSIDERATION OF THE WIND FIELD IMPROVE PREDICTIONS OF ZOOPLANKTON ABUNDANCE IN HARP LAKE, ONTARIO?
(2013-02-14)The predictability of zooplankton abundance under wind-driven currents has rarely been explored and further study can help improve the understanding of zooplankton communities in aquatic ecosystems. In this study, we sought ... -
