CEEB | Conservation, Ecology, Evolution and Behaviour
We study how an incredibly diverse set of organisms from microorganisms to animals make their way in the world using observation, experiments, and theory. Our world-renowned research spans from microcosms to the entire globe. This breadth enables a more complete and integrated view of biological systems, which is reflected in our undergraduate courses, graduate courses and our research. We strive to cut across traditional research areas, build upon foundational science, and inform conservation and management.

Rowan Barrett, Associate Professor

Office: Redpath Museum | Email: rowan.barrett [at]

My work is motivated by a desire to understand the genetic basis of adaptation to changing environments. My research group uses empirical approaches in population genetics, evolutionary ecology, and molecular biology to ask questions about the reciprocal interactions between ecological and evolutionary processes in a variety of key study systems, including stickleback fish, deer mice, Anolis lizards, and microbes.

graham bell

Graham Bell, Professor

Office: Redpath Museum, 201 | Email: graham.bell [at]

I work in the field of experimental evolution, using micro-organisms as model systems. This approach enables me to study the dynamics of natural selection in real time. Most of my work has been done in the laboratory, but I also conduct field experiments to achieve greater realism. I have recently conducted a series of experiments to investigate ‘evolutionary rescue’, the recovery of stressed populations through natural selection.

Gregor Fussmann, Professor & Chair

Office: Stewart Biology, N8/15 | Email: gregor.fussmann [at]

People in the Fussmann lab are interested in the ecology and evolution of populations and communities. To study eco-evolutionary dynamics we use aquatic model organisms and conduct controlled experiments in the laboratory and in the field. We believe that this approach, combined with mathematical modelling, will contribute to a better understanding of the dynamics of real ecosystems such as lakes and streams.

Andrew Gonzalez, Professor

Office: Stewart Biology, N3/2 | Email: andrew.gonzelez [at]

We study the causes and consequences of biodiversity change: 1) global change impacts on biodiversity and ecosystems, 2) rapid evolution in changing environments, and 3) the application of network science to the conservation of biodiversity at regional scales. We test and develop theory with experiments in the field and lab, and use large databases to synthesize knowledge.

The lab’s long-term research goals are to advance our understanding of the structure and functioning of lakes and to quantify how these ecosystems have responded to the accelerated rate of change introduced by human activities since the Industrial Revolution. To achieve these goals, our group develops, scrutinizes and integrates data from different sources: lake surveys, time series and field experiments.

Frédéric Guichard, Professor

Office: Stewart Biology, N8/14 | Email: frederic.guichard [at]

Theoretical ecology and complex system theories applied to coastal ecosystems and marine reserve design. We study the emergence of large scale properties of species assembly and ecosystem function from local interactions among individuals. We adopt a multidisciplinary approach involving mathematical and computational tools, field experiments and the analysis of large datasets.

Mélanie Guigueno, Assistant Professor

Office: Stewart Biology, N7/3 | Email: melanie.guigueno [at]

We combine field and laboratory approaches to examine ecology’s influence on behaviour, cognition, and the brain with both proximate and ultimate approaches. We incorporate fine-scale brain measurements, such as neurogenesis. Much of our work is on spatial memory in the context of avian brood parasitism, migration, and foraging ecology.

anna hargreaves

Anna Hargreaves, Assistant Professor

Office: Stewart Biology, N6/1 | Email: anna.hargreaves [at]

Evolutionary ecology of species distributions and species interactions. We tackle topics of theoretical and conservation interest, including: local adaptation and dispersal evolution at range edges; how these affect range stability and responses to global change; geographic patterns in biotic interactions and biodiversity. Research emphasizes field experiments (usually with plants because they're the best), complemented by data synthesis and lab experiments.

Behavioural plasticity allows some animals to cope with environmental change better than others. In birds, we can measure differences in plasticity by the frequency with which novel foods or novel searching and handling techniques are incorporated in the diet and feeding repertoire. Our lab uses this measure, innovation rate, to test predictions on the ecology, evolution and mechanisms, both neural and behavioural, of opportunism and intelligence.

Virginie Millien, Associate Professor

Office: Redpath Museum | Email: virginie.millien [at]

My research focuses on the patterns of variation and evolution of biodiversity in a changing environment. I am particularly interested in the study of the effects of climate warming, habitat fragmentation, or isolation on small mammal diversity, and the consequences on the emergence of Lyme disease in southern Quebec.

laura pollock

Laura Pollock, Assistant Professor

Office: Stewart Biology, N3/11A | Email: laura.pollack [at]

We study how and why biodiversity is distributed from local assemblages to global species pools. To do this, we use predictive modelling that draws from a range of subfields (macro-ecology, community ecology, biogeography and phylo-geography) and data (traits, phylogenies, experts). We also work to use this multi-dimensional biodiversity knowledge in conservation planning.

Catherine Potvin, Professor

Office: Stewart Biology, S3/27 | Email: catherine.potvin [at]

We study forest conservation and climate change, specifically the conservation of social-ecological landscapes, biodiversity and ecosystem function and landscape-level carbon stocks to inform environmental policy. Our current research spans from remote sensing to capacity building and conflict resolution. Working with the Indigenous Emberá of Panama since 1994, we have developed participatory approaches to integrate the human dimension into biological analysis.

simon reader

Simon Reader, Associate Professor

Office: Stewart Biology, N7/12 | Email: simon.reader [at]

Animal behaviour, behavioural ecology and behavioural neuroscience: We study the mechanisms, development, and evolution of behaviour, with a focus on social cognition and learning. In particular, we study how diverse patterns of environmental variability shape reliance on different information sources, the neurocognitive mechanisms underlying social learning, and the evolutionary consequences of behavioural flexibility. Much of this work is with fish.

Anthony Ricciardi, Professor

Office: Redpath Museum | Email: tony.ricciardi [at]

Our lab investigates the causes and consequences of biological invasion, focusing on freshwater ecosystems. We address fundamental questions such as why some species are highly successful invaders, what makes an ecosystem vulnerable to invasion, and how invasive species alter their environment. Our recent work explores the effects of climate change on the success and impact of introduced fishes.

The interface between plant physiology and ecosystem nutrient cycling - what physiological and chemical traits and controls shape plant nutrient uptake? And how do these plant traits drive ecosystem processes such as soil nutrient availability, productivity and trace gas emissions?

jennifer sunday

Jennifer Sunday, Assistant Professor

Office: Stewart Biology, N8/3 | Email: jennifer.sunday [at]

We are interested in understanding how species distributions respond to environmental change, through direct effects, adaptive capacities, and biotic interactions. We use macroecology, natural experiments, and controlled experiments informed by theory to build a predictive understanding of how population and communities will respond further to climate change.
