Well, it’s official: I am now Professor. I wasn’t going to make a big deal out of the promotion, but the news was circulated on Friday and the various notes of congratulations have been nice to receive. The best consequence, though, was the (complete) surprise Zoom call this morning with 18 current and former students (including some who I haven’t had a conversation with for a long time). It was just a quick call organized by Ella Maltby (true to form, the Wyeth Lab social organizer) and it was very cool to see everyone, even if briefly. It was such a surprise (nice work, Carmen, asking for technical help with Zoom!) that I was pretty flustered.
So this post is to do what I didn’t do very well in the Zoom call… A massive THANK YOU to all my students, current and past, whose enthusiasm, dedication, creativity, tolerance, etc etc. has helped me along the way as well as my family, department, and colleagues far and wide. Thank you, I couldn’t have done it alone.
The Biology Department at St. Francis Xavier University (Antigonish, Nova Scotia) is seeking a research technician to conduct weekly monitoring of pathogens in wastewater. As part of a province-wide project with several Nova Scotian universities, we will be applying a newly developed protocol that effectively and safely detects specific pathogens in wastewater. All work will be conducted in Antigonish, an on-the-job training for the sampling and measurement protocols will be provided.
This was a collaboration led by Jim Williams and his students Megan Fraser and Tyler Winsor. And it is the first ever botanical study RCW been part of. With our analysis and stats help, they showed that sediment from Boat Harbour that predates its conversion into an industrial waste treatment lagoon can effectively support the growth of both cord grass and eel grass. These are promising results for the planned restoration of Boat Harbour (or A’se’k to give its Mi’kmaq name) once the industrial sediment layer has been removed.

A new first for the Wyeth Lab: a publication as a direct consequence of a conversation at the Canadian Society of Zoologists meeting. We (Shelby Brown [Wyeth Lab alumn] and RCW) have helped out Laura Eliuk and Jillian Detwiler with some video analysis of snail behaviours. The primary result: some interesting changes in how attractive one species of snail is to another species of snail, depending on whether the first snail is infected by a parasite that is also a parasite of the second snail! As you might expect: the parasite seems to make the first host more attractive to the second host. The implication, thus, is host-behaviour modification via a chemical cue! Looking forward to more productive work in this collaboration!

Great work from everyone in the lab last week. Methods and more presentations, but not using PowerPoint. Instead, we used Zoom + Google Jamboard (because whiteboard options in Zoom and Teams had limitations). Mock deployments, presenting graphs or activity heat maps, and nervous system structure were all covered. It was a great way to delve deeper into our advance prep for lab and field work (and also thesis defenses). Forcing the use of just a few images and some simple drawing helps foster a bit more of a story-telling approach, and was great at helping to spot gaps in planning.
It’s that time of year again, when we both welcome new faces into the WyethLab and our field research projects really ramp up. Although the pandemic restrictions mean we haven’t yet been able to actually do any lab or field work yet, lots of preparation is still happening as everyone works remotely. This summer, 14 lab members are making great use of MS Teams and working together on several different projects:
Two students are working on snail neuroethology: Carmen will be testing for electrophysiological reponses of chemosensory neurons, while new student Donica is working in collaboration with Roger Croll on catecholamine neuroanatomy.
Meanwhile, Ella (lobster toxicology) and Areej (snail navigation behaviour) are moving closer every day to defending their MSc theses.
And also an extra thank you to Chelsie Hall, project manager working behind the scenes to help keep things on the straight and narrow!
My name is Donica Larade and I am from Halifax, Nova Scotia. I just graduated May 2021 with a degree in biology at StFX. This is my second year working in the Wyeth lab as a research assistant. In the gastropod neuroanatomy group, I am currently working on two projects analyzing neurotransmitter distribution in the gastropod nervous system. Using immunohistochemistry, I’ve been labelling catecholamines in sea slug Tritonia exsulans and pond snail Lymnaea stagnalis, and I am thankful to help with furthering our understanding. I’m happy for the opportunity to have this experience, and will hopefully continue my work on invertebrates in the future.
