Sam, PhD student

Who am I and what is my fieldwork project?

I’m Sam. I’m a PhD Candidate in Dr. Orihel’s QE3 Research Group. I study the exposure and effects of microplastics to larval amphibians. Amphibians are some of the most sensitive vertebrates on the planet with 40% of species considered at risk. Pollution has been identified as a factor affecting their declines. Yet there is very limited knowledge on the effects of one of the most widespread pollutants: Microplastics. I use outdoor mesocosm experiments to mimic environmentally relevant conditions as I expose tadpoles to microplastics. We follow the tadpoles throughout their development to assess route of exposure, microplastic body burden, development, behavioural effects, growth, and possible mortality. Canada is currently working on their plastic management plan and these data can be used to inform policy and regulations that will help protect some of our most sensitive species.

What was the best part of fieldwork?

There are so many parts of fieldwork that I love. From the beautiful scenery, to the adorable tadpoles, to getting to spend an entire day in a canoe. But what I really love is how fieldwork makes me think. I can plan for months in advance and when it comes to the actual field days there will always be a new challenge or puzzle to figure out using the materials on hand. Every day is something different and it brings out a sense of adventure.

What was the most challenging part of fieldwork?

Both my field seasons were during difficult times in the pandemic. Because of the many restrictions and the more remoteness of fieldwork, it was extremely isolating and I often was only able to see one labmate at a distance outside. This time was difficult for many people, and I had a hard time being away from family and friends for months at a time with limited service. We had long days and were tired and sore by evening. I found that taking the time to enjoy my surroundings, my frogs, and the exciting parts of fieldwork helped and after 4 months of hard work I was even able to take vacation! Appreciate your time in the field, you will miss it when you’re stuck in the lab counting plastics.
