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.
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!
A number of events have occurred this past year: a federal election, a horrific plane accident, and a pandemic. A completely understandable side effect of these has been that that many research funding announcements have not been made. THAT means that the typical embargoes on publicizing the funding have effectively been extended indefinitely. However, these successes are important for the research we do, and particularly, for supporting the students who do so much of the work. So, although I cannot directly acknowledge the sources, I would like to announce…
A huge thank you to the great work by past students who have led up to this. Obviously, this does not compare to the larger events in the world, but the funding is going to make a huge difference for how 13 students spend their time this summer, and many others over coming years in the Wyeth Lab and elsewhere in the Biology Dept.
Alex Young has published his second article from his MSc. While working to adapt flourescent in situ hybridization (FISH) methods to work with Lymnaea stagnalis, two things became apparent. There’s a fair number of published protocols out there, and no one has consolidated all the variants in one location to help anyone in our position. So, he decided to do it himself – adding in the expertise of Dan Jackson, we’ve put together exactly what the title says it is: a technical review and guide to RNA FISH. Hopefully others looking to work with FISH for the first time or adapt an established protocol will find this helpful.

We are seeking a research technician to work as part of the Centre for Biofouling Research. Our fundamental and applied research program explores both marine biofouling (the growth of unwanted organisms on marine infrastructure) and novel low-toxicity approaches to antifouling (the mitigation of biofouling). The technician will help coordinate and participate in several ongoing research projects with respect to biofouling and environmentally-friendly antifouling. The technician will work under the supervision of Dr. Russell Wyeth, helping with many aspects of the CBR’s activities. The technician’s primary role will be to support the successful completion of the projects, working with both the supervisor and students to plan lab and field work, undertake sampling, and, once completed, prepare oral and written communications about the various projects. Administrative tasks in support of the supervisor will also be involved, as well as opportunities to engage with other active research projects.
