Who we are


We are a group of comparative physiologists interested in linking physiology to species distribution

Skye Butterson

BSc (Honours), Stellenbosch University (2015)
BSc, Stellenbosch University (2014)

For my Honours, I worked with Prof. Susana Clusella-Trullas associated with the Centre of Excellence in Invasion Biology. My thesis focused on transgenerational thermal plasticity in the invasive Harlequin ladybeetle, Harmonia axyridis.

Current research:

Broadly, I’m interested in the role of thermal stress in shaping species distributions. For my Masters, I’m studying the physiological mechanisms underlying local adaptation to cold stress as well as transgenerational plasticity in cold hardiness. This work uses the eastern spruce budworm, a North American boreal pest caterpillar, as a model. CV

Jarrett Blair

BSc (Honours), University of Guelph (2018)

As an undergrad, I worked with Dr. Robert Hanner and Dr. Steven Crookes on a project that used environmental DNA (eDNA) to predict habitat occupancy of Jefferson salamander (Ambystoma jeffersonianum). For my thesis, I assessed the viability of using sedimentary eDNA sampling protocols to detect Jefferson salamander populations. I also developed a novel approach for predicting Jefferson salamander habitat occupancy using a cumulative probability matrix.

Current research:

In general, I am interested in using machine learning and computer vision models to solve biological problems. For my Masters, I am working with the National Ecological Observatory Network Invertebrate Bycatch Project (NEONIB) to develop machine learning models that can identify invertebrates from pitfall trap images. I hope to be able to use this data to find spatiotemporal patterns in invertebrate morphology and predict how invertebrate community structure might change in response to climate change.

For my 4th year Honours project I am interested understanding the mechanisms of freeze tolerance in the intertidal mussel, Mytilus trossulus. In particular, I am interested in how osmolytes (which accumulate in high salinity conditions) and anaerobic by-products (which accumulate in hypoxic conditions such as low tide) influence the mussels’ seasonal freeze tolerance. 


Zeba Khan

Zeba is a fourth year Bachelor's of Science candidate studying Integrated Sciences. She is integrating topics in Biology, Physiology and Behavioural Neuroscience to understand how different species interact with their environments, especially under stress. Her directed studies research project focuses on effect of changing temperatures on the Eastern spruce budworm, Choristoneura fumiferana.


Brian Cho

I’m going into my fifth year of Biology, helping set-up the Marshall Lab in its new space. In addition, I currently have a project looking to find the distribution of heat shock protein 70 (HSP70) on sections of the Eastern Spruce Budworm through immunostaining.
