Hats off to Environment Canada, the Department of Fisheries and Oceans, and the Canadian Coast Guard for putting on a great open house today at the Canadian Centre for Inland Waters (CCIW)! Most of my lab (see picture below) agreed to a “lab outing” to the CCIW. I had always wanted to see what research occurs at CCIW, which is a building nestled directly under the Burlington Skyway in southern Ontario:
With the yoke of information control (http://www.macleans.ca/news/canada/when-science-goes-silent/) lifted following the election of a new government in 2015 (http://www.macleans.ca/society/unmuzzled-government-scientists-ready-to-discuss-a-decade-of-work/), it was amazing to see the enthusiasm in the faces of the scientists working hard to assess environmental impacts of human influences on wildlife, plants, and the ecosystems around us. Why these scientists were ever bureaucratically muzzled is beyond me.
Here we are looking pleased with ourselves:
Most of the lab in attendance. From Left to Right: Justin Bridgeman, Nicholas Skakich, Glenn Tattersall, Curtis Abney, and Philip Bartel. Susan Wang not in photo as she was still having conversations with researchers inside the building.
We even receive visitors badges that reminded me of a strange 1980s sci-fi show:
On the trip home, we even were stopped by the lift bridge, something I usually avoid when driving the QEW:
All told, I was extremely impressed with the open house put on by CCIW and wish to thank them for opening their doors to the public. Keep up the good work!
A couple of significant events occurred in the past couple of weeks in the lab, and I wanted to note them here.
My MSc student, Curtis Abney found out he is a recipient of an Ontario Graduate Scholarship for his research on the thermal biology of garter snakes. Congratulations, Curtis!
My MSc student, Justin Bridgeman, who is busy attending conferences this summer, received a travel support fellowship to attend the Fisheries Society of the British Isles annual meeting this July! Congratulations, Justin!
Last month, Canadian Nuclear Laboratories invited a number of researchers to witness the nightly roosting of chimney swifts in one of their ventilation stacks! They were kind enough to allow me to film using my thermal camera the gathering of over 1000 birds at ~8:45pm one evening. Now, if only I can find the time to help with writing code to help them count the birds entering the chimney! Here is a brief video and a link to CNL’s facebook site:
Congratulations to Susan Wang, MSc student working in my lab and co-supervised with Dr. Janet Koprivnikar (Ryerson University) for successfully defending her thesis on:
“Behavioural Thermoregulation and Energetics in Two Intermediate Hosts of Trematode Parasites”
Thank you for all members of the examining committee for their hard work and interesting defence discussions:
External Examiner: Dr. Carl Lowenberger, Simon Fraser University
Committee Members: Dr. Gaynor Spencer, Dr. Robert Carlone, Dr. Dorina Szuroczki
Her time in the lab was far too short, but we are proud of her accomplishments and for her hard work on an interesting project. Because of Susan, I can safely say that we can readily do interdisciplinary research! Ecological physiology of disease and host:parasite interactions is a fun topic and I’m glad to have had this project taking place in my lab and grateful for Janet Koprivnikar for funding, intellectual, and logistic support, collaboration, and supervision at every step.
Brock University’s Brock News has written up a great piece on Anne Yagi’s (an MSc student in my lab) research. Anne has worked for the Ministry of Natural Resources for a number of years and joined my lab to pursue questions into the overwintering physiology of snakes. The article below covers the Conservation Physiological approach she has been taking to understand neonatal rattlesnakes in a sensitive population. Hopefully we’ll be publishing on this soon. Congratulations Anne!
Following the CSZ meeting, a very kind graduate student from University of Winnipeg, Ana Breit, agreed to drive Justin and myself up to Narcisse, Manitoba on the last afternoon of the meeting. I brought the thermal camera with me, so I could document the spring emergence of garter snakes, and the writhing reproductive orgy that is customary at this field amazing site.
Here are some sample images in visual, thermal and thermal video:
Many thanks to the people at Nature north for maintaining this site: http://www.naturenorth.com/spring/creature/garter/Narcisse_Snake_Dens.html
My student, Justin Bridgeman and myself were the representatives from my lab this year. Unfortunately, I forgot to take photos of him speaking or of me defending my student, Katlyn Dundas’s poster.
For posterity, though, here are the clips from the CSZ program book:
Winnipeg was a great host city and the meeting was excellent. Always good to catch up with fellow Canadian scientists.
I just found out that the CNRS (Centre Nationnal de la Recherche Scientifique) did a write-up about work conducted during my 3 month sabbatical at the Université de Lyon with very hospitable colleagues, Dr. Löic Teulier, Dr. Damien Roussel, and Dr. Yann Voituron:
How I miss those guys.
They let me camp out in their lab for 3 months (Sept 2015-December 2015), helped me with renting a place in Lyon, and generally introduced me to the French attitude and ethic and their love of cheese and fine wine.
At long last, years of hard work in the field of Drosophila research has met with the fruition of this publication…maybe one day I will blog about the challenges of associated with this field of research. Now is not the time, but suffice to say, I will say this….if a paper on fruit fly phenotype is published and nothing about the husbandry, nutrition, and rearing conditions are provided, the research should be taken with huge grain of salt. Context is everything.

At long last, I’ve spent time fixing some sloppiness in my R package, Thermimage, as well as added functions for importing and exporting thermal images and videos. Partly still beta testing it on github for the time being but will eventually upload it CRAN once finalised.
Meanwhile for those using thermal imaging but frustrated at not being able to import or analyse images in an open source environment, consider trying this out:
Here is the proof of the exported raw file imported into ImageJ:
