Biography

I have had the rare privilege to turn my childhood fascination into a career. I grew up catching snakes, turtles and toads in the forests and creeks near my house. As a professor, I have the opportunity to share my passion for these animals and their conservation with students in the classroom and in the field.

I did my undergraduate degree at the University of Guelph. There I met herpetologists Ron Brooks and Jim Bogart, and so began my formal training in herpetology. I did my MSc under Ron’s supervision at Guelph, studying the population ecology of Spotted Turtles at their northern range limit. In the summers, I taught biology to kids at a canoe-tripping camp, and so got to combine my interests in biology, teaching, and the outdoors.

Between my MSc and PhD, I worked as a Lab Coordinator in the Cryobiology Lab at Miami University in Oxford, Ohio, USA. I worked with Rick Lee and Jon Costanzo, and their graduate and undergraduate students. I learned a whole new set of skills and gained an appreciation for physiological-ecology and the incredible adaptations that herps have for surviving winter.

After three years in the Cryo Lab, I decided it was time for me to return to graduate school, to answer the questions about latitudinal variation in turtle life histories that arose during my MSc research. So I left Ohio and moved to South Carolina to study the population ecology of Spotted Turtles at their southern range limit. I worked under the supervision of Tim Mousseau, an ex-pat Canadian, at the University of South Carolina in Columbia.

After completion of my PhD, I moved to Long Island, New York to live with my husband, Dr. Thomas Merritt who was doing a post doc at Stony Brook University (he is now a CRC here at Laurentian in the Department of Chemistry & Biochemistry). While in New York, I worked as an Adjunct Professor at Long Island University and as a research associate at Applied Biomathematics.

Then, in spring 2004, I was offered the faculty position here at Laurentian University, and so I moved back home to Ontario after 8 years in the USA. I have been a professor at Laurentian since July 2004.

Research

Research Program

My research program combines field and lab-based approaches, and basic and applied science. Projects in my lab address questions in the areas of evolutionary ecology and conservation biology of reptiles, including examination of the adaptive significance of life history variation, and the application of these data to mitigation and recovery actions. Recent and current research examined/examines variation in the life history and ecology of federally-listed turtle and snake species, with emphasis on demography, maternal investment, road ecology, spatial ecology and habitat selection. The physiological research examines questions about the adaptive bioenergetic, fitness, and thermoregulatory consequences of certain behaviours, particularly summer and winter dormancy, in reptiles.

Our research is funded primarily by NSERC and the Ontario MNRF through the Species at Risk Research Fund (SARRF) and the Species at Risk Stewardship Fund (SARSF). We have also received support from Environment Canada's Habitat Stewardship Program (HSP) and the Canadian Wildlife Federation. We are grateful to our partners, especially Ontario Parks, for their financial and in-kind support. 


Team Litzgus Research News

September 2018: The Litzgus Lab is just back from the CHS meeting in Kamloops, BC.  The Team presented 7 talks and 5 posters - wow!  It was a nice reunion of past and current lab members; an academic family spanning from 2007 to present.  

September 2018: The Litzgus Lab welcomes the new school year with new MSc student, Carter R, joining the Team. Carter comes from the Rollinson Lab at UofT, and has been part of the crew working on the long-term turtle study at the WRS in Algonquin Park.

July 2018: Exciting news from NSERC! Our CRD grant with Bruce Power was funded. We are looking for a new MSc student to start in January 2019 to undertake this project examining how changes in lake levels impact turtle spatial ecology and nest site selection.

May 2018: The Litzgus Lab and collaborators welcome four new graduate students: Cory T, Tharusha, Jonathan, and Matt M have joined the Team!

March 2018: Jackie received the Laurentian Research Excellence Award at the Research Week Gala and Awards Ceremony. Jackie also received a Mentorship Award from Magnetawan First Nation for her contributions to their long-term Species At Risk program.
Thanks to to the Team for their amazing contributions to these honours -- I couldn't get here without you!  

January 2018: More good news from NSERC!  We received an Engage Grant to begin a new partnership with Brookfield Renewable to examine the impacts of wind turbines on herp communities on the Prince Windfarm in SSM.  This will be the MSc project of Cory Trowbridge, starting in May.  

November 2017: Jackie has been using her sabbatical time to try her hand at creative writing.  She published a couple of articles in the online magazine called The Conversation.  One of her articles, about turtle hibernation, received over 80,000 reads in less than a week!  https://theconversation.com/the-secret-to-turtle-hibernation-butt-breathing-86727

September 2017: Team Litzgus, including the 2 newest members Gabby and Cory K, journeyed to the Prairies, to attend the CHS meeting in Brandon, MB.  The lab gave 2 talks and 4 posters.  Damien won best student talk and Steven won best student poster.  Holy cow!  Congrats to the Team, again!

August 2017: Litzgus lab members, former and present, attended the TSA/IUCN meeting in beautiful Charleston, SC.  The trip south started with a visit to Jackie's dissertation field site, Beidler Forest, where we caught one of her original study animals, female spotted turtle #6 (http://sc.audubon.org/news/reunion-under-trees).  The lab gave 3 talks and 2 posters at the meeting.  Steven won best student poster and Patrick won best student talk!  Amazing!  Congrats to Team Litzgus for doing Laurentian and Canada proud at this very international meeting! 

April 2017: Great news from NSERC!  Another 5 years of Discovery Grant funds secured.
