I am from Kingston, Ontario and am going into the fifth year of my undergraduate degree at St.FX. I am taking my major in Biology and my minor in Climate and the Environment. I love travelling, horseback riding and being outdoors. This past year, I began analyzing biofouling data as a Wyeth Lab volunteer. This summer, I will be switching gears and working on a lobster foraging project instead which I hope to do a directed studies project on in the fall. I am very excited for this opportunity and look forward to spending another summer in the lovely town of Antigonish.
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 $400,000, 3 year project to study foraging behaviour in the American Lobster, in response to both natural prey and baits used in the fishery.
- A $500,000 infrastructure project to get us a new laser-scanning confocal microscope for the Biology Dept at StFX
- A $235,000, 5 year grant to explore the neuroethology of navigation in aquatic gastropods.
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.

Congratulations to Wyeth Lab alumn Aaron Cogger, accepted into the Master’s of Marine Management program at Dalhousie University. Aaron worked on a couple different lobster projects. First, with collaborator Jim Williams on juvenile-adult interactions, and then helping Ella Maltby with her MSc research on toxicology of lobsters. Aaron completed his undergraduate in the Aquatic Resources program at StFX and also an Eleuthera internship in the Bahamas before taking this next step in his career.
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.
This position is offered through the CleanTech Internships program, so more details and applications are available here: Environmentally-Safe Antifouling Research Technician

In collaboration with Dr. Iain McGaw at Department of Ocean Sciences (DOS), Memorial University of Newfoundland (MUN), I am now accepting applications for a funded PhD student position to start September 1, 2020 (or earlier).
Kieran Murphy just tweeted out a great thread sharing more of the adventure (and misadventure) behind his MSc research. He did indeed find something “really quite important” and deserves a ton of credit! Check it out on twitter, or the full thread here.
[Thanks to Darius Kazemi’s spooler for helping to put thread together here in one place.]
A thread by Kieran Murphy
We got it done, my first publication😄
Thanks to the sea gods! 🧜♀️🧜♂️
A lot goes into all peer reviewed work, so here’s a thread about some of the fun stuff, the grunt work, and mess ups behind the clean-cut read about an invasive sea squirt in Nova Scotia (doi.org/10.3354/meps13…)
The Hard Graft
Location, location, location!
We monitored an invasive sea squirt called the vase tunicate on the coast of Nova Scotia and tested if its variable abundance was related to water conditions (i.e. temperature, salinity and pH)
To monitor sea squirts, one needs settlement collectors, many, many settlement collectors!
You need a solid vehicle (StFX Biology truck RIP) or many flashy rental cars to fill up with gear and to drive all around the coast of NS (approx 3,500 km) once a month from May to October in 2014 and 2015
Attach all of the settlement collectors and environmental data loggers to floating docks at 15 different field sites. Also return to photograph the settlement collector plates, upload data logger info and calibrate loggers
When I locked the car keys in the trunk
Yeah, it’s a trunk because I was in Canada ae!
Or when the data loggers got biofouled (ironic right?) or inexplicably corroded
P.S. copper wire and mesh are your friends to counter pesky data logger biofouling!
Or when one of your floating docks goes missing!!!
Don’t worry, there it is
Holy moly, did I see some heckin good sunrises and sunsets though!
And what aboot that wildlife (terrestrial………..EWWW!)
Aquatic (at least partially)………..CUTE!
I lived in a winter wonderland (hell) for three whole winters!
Crazy fall colours 🍁🍁🍁
Fall = Autumn
Looked at settlement plate images like this for days….weeks….no, months, counting how many critters were where and when
Got to work, no matter the conditions.
Nothing could keep me from grabbing a hot cup of filter coffee that’s been simmering on the hotplate for hours and counting those squares of sessile invertebrate filth
And at the end of the day, we discovered something quite important:
while temperature and salinity are good predictors of vase tunicate presences/absence distribution, they do not predict the abundance of the species very well
This could have important implications for the monitoring and distribution modelling of other sessile marine invertebrates
If you can’t access the paper, please just DM me for a copy
And don’t forget folks, always be sun🌞and sea🌊 safe!
Alex Young has published the first (of hopefully three!) articles from his MSc. This first one is a key step for a new way to explore the peripheral nervous system of gastropods. Working with transcriptome data shared by Dan Jackson and with Carmen Landry‘s help in the lab, Alex established which genes have highly stable gene expression in the pond snail, Lymnaea stagnalis, and therefore which would be effective as a reference when studying the relative expression levels of other genes (such as genes expressed in neurons – that’s manuscript number two in the works).

Wyeth lab alumn Kieran Murphy has just published his first two peer-reviewed articles. The first documents his (massive) efforts during his MSc to survey both abundances of the invasive vase tunicate Ciona intestinalis and potentially corresponding environmental conditions. His goal was to test whether temperature, salinity, etc. could explain variations in the abundances of this species around Nova Scotia. The result? No clear links between abiotic conditions and population growth patterns, which has implications for predicting and managing the spread of this nuisance species. The second is an exciting new collaboration that developed as an offshoot from his MSc. Ping Ni from Aibin Zhan‘s group used Ciona collected by Kieran and his temperature data to discover temperature-linked epigenetic changes in an invasive species. Congrats to Kieran and Ping!
A huge thanks to Michelle, Areej and new volunteers Sarah and Sam. We wrapped up this year’s data collection on our biofouling and antifouling projects. Eight separate surveys spread across 3 sites meant an 11 hour day and trailer full of deployment frames by the end of it. Fantastic weather offset the stinkiness!
