Rob Belanger
Research Associate (2018-)

Rob is collaborating and coordinating field and academic research related to bison ecology in northern Alberta. He is collaborating with First Nations, Metis, provincial and federal governments, and forestry and energy industries to achieve science and Traditional Knowledge-based bison and ecosystem conservation and management. He is coordinating with undergraduate and graduate students to answer questions regarding bison movement and habitat use, bison-abiotic-biotic interactions, and ecosystem pattern and fluctuation. Outcomes of bison research will contribute to improved knowledge of bison ecology, and better conservation and management practices. Rob recently completed a Masters degree with the ACE Lab, and stayed on to continue his research on bison ecology. Rob enjoys backcountry hiking excursions and is an avid cyclist, and is an advocate ot voluteering and collaborating with conservation organizations.
Jacqueline Dennett
Research Associate (2019-)

Jacqueline's focus is on culturally valued vascular plants in the Oil Sands Area, working with Indigenous communities and other partners to develop research projects focused on conservation and mitigation for these species in a rapidly changing, fragmented landscape. Her work includes developing online plant atlas' for species such as pitcher plant, as well as partnering in community-driven projects. She was previously involved in the Terrestrial Vascular Plant Monitoring Project for the Lower Athabasca, and completed her PhD in Conservation Biology at the University of Alberta in 2018.
Federico Riva
Post-Doctoral Fellow (2019-)

Federico's PhD, supervised by Scott Nielsen and John Acorn, revealed many responses in butterfly behaviour, diversity, and distribution to the habitat fragmentation associated with in-situ oil sands. He is now expanding his research to incorporate a strong spatial focus by including elements of landscape ecology and systematic conservation planning, while remaining fond of community ecology, biodiversity theory, and (of course) butterflies.

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
Ph.D. candidate (2014-)
Thesis Project
Population Regulation and Habitat Selection of Grizzly bears

Clayton's research is on population regulation and habitat selection of grizzly bears. In particular, he is interested in examining how spatial and temporal factors affect regional patterns in population density, including patterns in huckleberry, and how these factors interact to regulate grizzly bear populations. When not collecting grizzly bear hair, he spends his time in the backcountry hunting, fishing and backpacking.

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.
Laureen Echiverri
Ph.D. Candidate (2017-)

Project Title: Seismic lines and their edge effects on understory vegetation. 


Laureen is studying the edge effects of seismic lines on understory vegetation in Alberta's boreal forest. Her thesis examines how these linear corridors affect the richness, composition, and population dynamics of the understory vegetation in the adjacent forest. In addition, she explores how regeneration on these linear clearings might be improved.
Amy Macleod
M.Sc. student (2015-)
Thesis Project
Sympatric relationships between grizzly & black bear in Glacier National Park, Montana

Amy is interested in ecology and conservation of Rocky Mountain bears, her masters is focused on using DNA and stable isotope analysis to investigate the diet of bears in Glacier Park, Montana. In her spare time, she can be found hiking with her dog, cross country skiing, and traveling.
Thea Carpenter
M.Sc. student (2015-)
Thesis Project
Songbird responses to in situ energy extraction in lowland boreal forests

Over the past few years Thea has had the opportunity to take part in projects that involve traipsing under mature pine, blundering through willow thickets, tromping over old spruce downfall, and squelching in peatlands to monitor boreal songbird populations.  She is keen to gain a better understanding of how we can apply ecological principles to further the conservation and management of these captivating habitats.  In particular, she is interested in mechanisms driving songbird responses to habitat modification by anthropogenic disturbances.

Graeme Nordell
M.Sc Student (2018-)

Graeme is working to compile data on invasive plant species in the fragmented forests of northern Alberta. Through existing vegetation counts and his own examination of soil seed banks, he hopes to demonstrate the extent to which these linear disturbances may act as corridors of invasion. When Graeme isn't stretching his nature-legs, he loves board games, craft beer, and going to the movies. If anyone can't remember the name of "that one actor who was in that movie about the thing", he's the guy to ask!
Connor Nelson
M.Sc student (2018-)

Connor is studying linear disturbances caused by oil exploration in the boreal forest of northeastern Alberta, and how they effect the local pollinator communities. He is gathering a wide variety of insect samples with the hope of understanding how these disturbances impact the behavior and community structure of the pollination networks in the area. Connor is broadly interested in entomology, evolution, and ethology, but beyond research, he enjoys teaching, hiking, and cooking!
