A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation
(Oxford University Press, 2019)Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) ... -
An adiponectin-S1P axis protects against lipid induced insulin resistance and cardiomyocyte cell death via reduction of oxidative stress
(Biomed Central, 2019-02-21)Background: Adiponectin exerts several beneficial cardiovascular effects, however their specific molecular mechanisms require additional understanding. This study investigated the mechanisms of adiponectin action in the ... -
Anaphase Chromosomes in Crane-Fly Spermatocytes Treated With Taxol (Paclitaxel) Accelerate When Their Kinetochore Microtubules Are Cut: Evidence for Spindle Matrix Involvement With Spindle Forces
(Frontiers, 2018-07-24)Various experiments have indicated that anaphase chromosomes continue to move after their kinetochore microtubules are severed. The chromosomes move poleward at an accelerated rate after the microtubules are cut but they ... -
A bee diversity survey in oak savannah habitats in Rondeau Provincial Park, Ontario
(Heritage Resources Centre, University of Waterloo, 2004)A survey of bee diversity was conducted in two oak savannah habitats - Oak Savannah 3 (03) and South Point (SP) - in Rondeau Provincial Park in Southern Ontario, Canada. The bee community composition of 03 and SP were ... -
Bees collect polyurethane and polyethylene plastics as novel nest materials
(Ecological Society of AmericaEcological Society of America, 2013-12-31)Plastic waste pervades the global landscape. Although adverse impacts on both species and ecosystems have been documented, there are few observations of behavioral flexibility and adaptation in species, especially insects, ... -
CAPA neuropeptides and their receptor form an anti-diuretic hormone signalling system in the human disease vector, Aedes aegypti
(Nature, 2020)Insect CAPA neuropeptides are homologs of mammalian neuromedin U and are known to influence ion and water balance by regulating the activity of the Malpighian ‘renal’ tubules (MTs). Several diuretic hormones are known to ... -
Characteristics of expanding and stable populations of garlic mustard in Carolinian parks
(Heritage Resources Centre, University of Waterloo, 2002)Garlic Mustard (Alliaria petiolata) is a short-lived monocarpic perennial introduced to North America in 1868 which reached Canada in 1879. It was first introduced to Point Pelee National Park in 1969 and Rondeau Provincial ... -
A checklist for choosing between R packages in ecology and evolution
(Wiley, 2020)The open source and free programming language R is a phenomenal mechanism to address a multiplicity of challenges in ecology and evolution. It is also a complex ecosystem because of the diversity of solutions available to ... -

Coaching for life -- my life
(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 -
Comparing motion capture cameras versus human observer monitoring of mammal movement through fence gaps: a case study from Kenya
(2016)Monitoring the movement and distribution of wildlife is a critical tool of an adaptive management framework for wildlife conservation. We installed motion‐triggered cameras to capture the movement of mammals through two ... -
Conservation Genomics of the Declining North American Bumblebee Bombus terricola Reveals Inbreeding and Selection on Immune Genes
(Frontiers Media, 2018-08-10)The yellow-banded bumblebee Bombus terricola was common in North America but has recently declined and is now on the IUCN Red List of threatened species. The causes of B. terricola’s decline are not well understood. Our ... -
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 ... -
