Congrats to Katherine P who led this manuscript as well as Kylie, Lexie, Ally, and Emmerson who all shared in the work. Using an image time series of macroscopic marine inverts, we show that even a single dose of ultraviolet light can reduce or delay marine biofouling. In addition, by adding an analysis of the new settlers immediately before and after the ultraviolet treatment, we show that the mechanism of action is probably direct toxicity of the ultraviolet light for those new settlers.

Dynamic Biofouling Research Technician Position Available

NOTE: this position has been filled

The Wyeth Lab and Centre for Biofouling Research (CBR) at St. Francis Xavier University is seeking a research technician. 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 develop and coordinate a new dynamic testing system that incorporates water flow into our field work. Real-world conditions for marine infrastructure typically includes water movement over surfaces colonized for biofouling: ship hulls during vessel travel, aquaculture pens during tidal flow, etc. The technician will contribute to designing, prototyping and operating a dynamic test system that generates flow over novel antifouling technologies. The technician will work under the supervision of Dr. Russell Wyeth. Activities working towards completion of the project will entail working with both the supervisor and students to plan and implement field work, undertake sampling, and, once completed, prepare oral and written communications about the project. Interaction with industry members and other stakeholders will also be expected. Administrative tasks in support of the supervisor will also be involved, as well as opportunities to engage with other active research projects.

Note: position is subject to final budgetary approval once a candidate is selected  

Duties and responsibilities

• materials management

a busy Wyeth lab

Lots going on this summer in the lab and field! The lobster foraging group (Grace, Aidan, Gavin , James, and Laura) are continuing to use underwater video and audio to record how different types of lobster bait and natural prey affect foraging responses and other behaviours in American lobsters. The biofouling group (Ally, Kristyn and Kylie) are busy testing the effectiveness and validating the low toxicity of graphene-based antifouling coatings (formulated by our industry collaborators, GIT) as well as continuing to explore the relative effectiveness hourly vs daily cycles of UV-light as an antifoulant. The gastropod neuroethology group (Makayla, Kali, and Noah) are tackling three different projects with pond snails: how they move in response to fine scale odour and flow stimuli, testing electrophysiological responses to food odours in the lips, and some more work on the neuroanatomy of the cephalic sensory organs (to take advantage of our department’s brand new confocal microscope).

Kali Hudson

My name is Kali Hudson and I am from Antigonish, Nova Scotia. I’m going into my fourth year at StFX planning to graduate with an Advanced Major in Biology and a minor in Psychology. I love sharing my passion for science and I spent the last two years working as a science outreach leader with X-Chem Outreach. This is my first summer researching with the Wyeth Lab as part of the gastropod neuroethology project, where I will be using electrophysiological techniques to study the nervous system of the great pond snail, Lymnaea stagnalis. This project is a perfect intersection of my interests in biology and psychology and I’m so excited to be involved!

Aidan McGowan

My name is Aidan McGowan, and I am from Annapolis Royal, Nova Scotia. I am going into my second year at StFX, where I am taking a BSc in Biology. This is my first summer working with the Wyeth lab, specifically assisting with the Lobster Foraging group. I am grateful to be a part of this lab, as it is extending my knowledge, as well as firsthand experience with collecting data out in the field. It has also cemented my plan in wanting to eventually become a marine biologist. I hope to continue with the Wyeth Lab throughout my BSc as it would be a great asset for my degree and future research ​opportunities.

James Hanlon

My name is James Hanlon, I grew up in Cambridge, Ontario but now live in Linwood, Nova Scotia. I am going into my second year here at StFX and will be majoring in Biology. I enjoy playing guitar and being outdoors whether it be camping or fishing I love the fresh air. I will be working on the lobster foraging project this summer with Wyeth Lab for my first foray into the world of research, excited to learn many skills and techniques. I hope doing research will help me ascertain what I’m passionate about and help guide me towards a future I enjoy. I’m delighted to be a part of Dr. Wyeth’s team this summer and hope I can work with such amazing people in the future as well.

Noah Ruscica

My name is Noah Ruscica and I’m from Aurora, Ontario and I just finished my first year at StFX pursuing an Honours in Biology with a minor in Chemistry! I am extremely excited to be working with the Wyeth Lab and cannot wait to develop and strengthen all my skills throughout this summer, and hopefully many more. As a member of the Gastropod Neuroanatomy team, I will be studying the nervous system of pond snails and performing electrophysiological experiments with the goal of gaining insight on how this organism’s behaviour is influenced by its sensory organs. With my true passion of understanding and learning more about the crossover between the central sciences, this project presents the perfect opportunity for me to develop, demonstrate and learn new and interesting skills that will benefit me in both my research and academic fields!

Kristyn Boutilier

My name is Kristyn Boutilier and I am from Antigonish, Nova Scotia. I recently graduated from StFX in May 2022 with a Bachelor of Science in Biology with Distinction. I’m excited to begin my second summer working with the Wyeth Lab on the biofouling project; doing research on environmentally friendly antifouling treatments for marine vessels. I love spending time outside and near the ocean, and I’m very interested in pursuing a future research career in marine biology or ecology. Working with the Wyeth lab has given me the amazing opportunity to learn and experience research in a hands-on setting, and I’m very grateful for the insight into future career paths it has provided.
