I earned my bachelor's and first master's degrees in Environmental Studies from the National University of Kyiv-Mohyla Academy in Ukraine, where I worked in the field of bioremediation. Russia's invasion interrupted my studies, and I served in the Ukrainian army for eight months. After my service, I joined the Waterloo Wetland Lab as a Summer Field Technician through a student exchange program supported by Mitacs. After an intense summer of fieldwork, I decided to pursue a second master's degree in the laboratory, and I am currently a graduate student at the University of Waterloo, working under the supervision of Dr. Rebecca Rooney. My research focuses on the dynamics of changes in wetland forage value for key waterfowl species following the removal of invasive Phragmites australis from Ramsar-designated wetlands and internationally recognized birding sites at Long Point and Big Creek National Wildlife Areas on the northern shore of Lake Erie. Invasive Phragmites australis poses a significant threat to waterfowl habitats by displacing native plant species and altering the availability of high-quality forage, as its increasing dominance in the ecosystem impacts the composition of waterfowl diets. My work aims to assess these changes to inform wetland restoration and conservation strategies.

Invasive Phragmites australis is a threat to wetland biodiversity and integrity across North America. My project is investigating the use of insect-based biological control for suppression of invasive Phragmites australis using two stem-boring moths. My research is part of the broader pilot program in North America for the biological control of invasive P. australis.

Microplastics are one the most abundant forms of aquatic pollution in the world today, with studies indicating that every level of the food web interacts with this manmade contaminant. My research focuses on how freshwater invertebrates are affected by microplastics and how they, in turn, may affect microplastics in the environment.

Urban stormwater ponds can simultaneously harbour incredible biological diversity and heavy contaminant loads, but are largely neglected by water monitoring and ecological assessment efforts. My research will help to develop a new and biologically-relevant tool for detecting the presence and concentration of pollutants in stormwater using biofilm (a.k.a. microbial slime!) sampling across a gradient of urbanization.

I will be studying carbon storage and sequestration in The Meadoway, a restored meadow along a hydro corridor in Toronto. Specifically, I will be trying to determine the degree to which turfgrass-to-meadow restoration enhances carbon storage and sequestration. Before starting here as a student, I worked in the Waterloo Wetland Lab as a technician for most of the year after finishing my undergrad in Biology also at UW. Outside of this work, I enjoy birdwatching, reading, listening to music and playing board games among other things.

My project involves using trait-based ecology to promote the active restoration of Long Point wetlands after the removal of invasive Phragmites australis. I’m hoping to help the native seed bank by creating and adding seeding prescriptions onto them to bolster their natural biotic resistance against P. australis.

Josh Pickering is a community ecologist interested in spatio-temporal trends and trophic interactions influencing bird communities. His current research focuses on evaluating long-term trends and response of breeding birds to adaptive white-tailed deer management at Long Point, Norfolk County, Ontario, Canada, following a prolonged period of deer overabundance.

It is well-known that overabundant white-tailed deer populations in North America have significant and often detrimental effects on ecosystems, yet few studies have examined the recovery of ecological communities - especially a breeding bird community - after a period of deer overabundance. It is the goal of this research to; assess trends in breeding bird species over time, evaluate community responses to changes in vegetation, local climate, and regional bird populations, and analyze regional differences to inform bird conservation efforts in Ontario.

This research at the University of Waterloo is supported by Birds Canada, Mitacs, an Ontario Graduate Scholarship (OGS), and a President's Graduate Scholarship.

My project focuses on using eDNA metabardocing to better understand biodiversity in urban ecosystems. I focus on stormwater ponds and working with the Residential development Impact Scorecard for the Environment (RISE) to induce ecological best practices in urban developments.

I am investigating the fate and effects of microplastics on freshwater algae. My research involves intensive field work during the spring and summer months at the Experimental Lakes Area (IISD-ELA), as part of a multi-disciplinary collaborative project known as PELAstics. Freshwater lakes are our greatest resources, yet they are currently inundated with plastic and microplastic pollution.
