Current Students
Jessica Stolar
Ph.D. candidate (2011-)
Thesis Project
Climate change effects on rare plant and butterflies of Alberta

Jessica's research is on conservation planning in the presence of climate change. Specifically, she is using environmental niche modeling to describe current species distributions for 200+ rare vascular plants and butterflies in Alberta and projecting changes in their distribution (potential habitat) with climate change. This will be used to identify gaps in the current conservation reserve design in Alberta and to recommend important sites in Alberta for future conservation. The output of this work will be posted on the Alberta Species Conservation Atlas page.
Clayton Lamb

Jacqueline Dennett
Ph.D. candidate (2014-)
Thesis Project
Detection and translocation of rare plant species in boreal forests

Jacqueline is interested in rare plant species associated with fens in boreal Alberta. Her research is on both survey methodology for improving rare plant detectability during environmental assessments and the effectiveness of using translocations as a mitigation tool for developments.  Her work will assist with developing standardized guidelines for these practices. Jacqueline likes to joke about self-torture in choosing to study fen species but genuinely finds these environments to be some of the most beautiful in Alberta.
Federico Riva
Ph.D. candidate (2015-)
Thesis Project
Effects of forest fragmentation from situ oil sands on butterflies

Federico is studying how linear disturbances associated with in situ oil sands developments in northern Alberta affect butterfly communities, movement rates and populations of rare species such as the cranberry blue butterfly. He is broadly interested in ecology and conservation, as well as ethology and evolution. He is interested in using butterflies as a model system to assess environmental conditions and ecological processes (e.g. mimicry, cryptic species, parasitism, etc.).  Besides his scientific interests, Federico loves to play basketball, hike, travel and generally to explore new places. He also loves Italian cuisine and blues music.

Zachary MacDonald
Ph.D. candidate (2015-)
Thesis Project
Island butterfly biodiversity & biogeography

Zachary is studying what island traits (size, isolation, habitat heterogeneity, etc.) may be contributing to patterns of biodiversity (butterfly, plant and bird taxa) observed on islands occurring on Lake of the Woods, ON. The main focus of his research is on butterfly ecology—specifically on how butterflies perceive and utilize their island habitats. When dealing in matters of conservation, investigating how the taxa we wish to preserve perceive their environments is paramount. Though studying biodiversity on these naturally occurring islands, Zachary hopes to shed light on how habitat fragmentation may be affecting levels of biodiversity found on anthropogenic habitat islands, which are created through various human practices and developments. Apart from catching butterflies, Zachary enjoys both playing and coaching tennis, as well as travelling, mountain biking, backpacking, and fishing.

Angelo Filicetti
Ph.D. candidate (2016-)
Thesis Project
Forest recovery and successional trajectories on seismic lines

Angelo is studying the recovery/regeneration of seismic lines created by oil sands exploration and extraction, the largest contributor of forest fragmentation in northeastern Alberta. Seismic lines contribute to changes in biodiversity and in particular, to declines in woodland caribou. However, natural rates of recovery on seismic lines are largely unknown. Understanding where natural recovery is occurring or is arrested, as well as how fire affects these processes, is therefore a priority. Lastly, Angelo is examining the effectiveness of active restoration treatments and where they will be most beneficial.
Christopher Souliere
Ph.D. candidate (2017-)
Thesis Project
Assessing landscape carrying capacity in grizzly bears to forest harvests and wildfire through modeling and simulation

Christopher Souliere is a PhD student in the Applied Conservation Ecology (ACE) Lab at the University of Alberta. He obtained his Masters in Biology at Carleton University, which focused on simulating the detection patterns of birds flying past marine radars. His PhD research focuses on modeling and simulating grizzly bear food resource supply, distribution and behavior in the Alberta Foothills. In particular, he is examining the effects of fire and forestry clearcuts on bear food supply, as well as exploring optimization analyses that consider bottom-up factors within forest harvest planning tools. He is also interested in investigating methods that estimate population size; and developing agent-based models to simulate grizzly bear population dynamics and behavior in changing landscapes, with the aim of answering questions that remain pertinent to management objectives. Apart from research, he enjoys climbing, skiing, golf and flying RC aircraft. Prior to graduate school, he worked as a research assistant at the National Wildlife Research Centre (NWRC) in Ottawa.
Lee Hecker
Ph.D. candidate (2017-)

Lee is a PhD student who is investigating the ecology of the Ronald Lake herd of wood bison (Bison bison athabascae) in northeastern Alberta. This small herd roams a home range that expands from the oils sands north to the south eastern tip of Wood Bison National Park, putting them at the front lines of conversation biology. Specially, Lee is exploring the herd's response to anthropogenic and natural (i.e., wild fires) disturbances, the selection of specific calving grounds, and the how wood bison transform their landscape. In his spare time, Lee enjoys backpacking, diving, skiing/snowboarding, playing basketball and soccer, photography, and biking. When he is adventuring, Lee is happy.
