I am interested in the causes and consequences of variation in species’ life histories and seasonal phenologies—particularly as these traits relate to species interactions. A primary application of my research is in understanding ways that climate change and other forms of global change affect pollinators (especially native solitary bees) and pollination. My work so far has focused mainly on bees and plants in natural habitats, but I am also interested in how better knowledge of native bee ecology can benefit agriculture.

Peter is interested in the spatial and temporal variation in interspecies interactions and how that variation influences reproductive success and evolutionary transitions in the interacting species.  He is currently studying the role of pollinators in correlated evolution between flowering phenology and floral morphology in the genus Mertensia (Boraginaceae).

Doctoral student, co-supervised by Prof. Chris Buddle (McGill), since 2015
E-mail: gail.macinnis “at”

Gail is interested in how bee diversity affects the yield and quality of agricultural food crops. She is studying pollen deposition and foraging behaviour of wild and managed bees and their efficiency as pollinators of commercial and organic strawberry crops.

Cécile AntoineCecile
Doctoral student since 2017

E-mail: cecile.antoine.31 “at”

Cécile is interested in the factors that limit populations of wild bees and hence the pollination service provided by these bees, in an agricultural environment. She is working more specifically on populations of solitary ground-nesting bees in the margins of farms fields that differ in farm management.

Sébastien is interested in the defense mechanisms used by plants to protect their pollen. He will examine the causes of the presence of plant defense compounds in pollen by comparing their effect on pollinators, pollen thieves, and pollen microorganisms, and evaluate their consequences by looking at their role in the evolution of the genus Osmia.

Gabriel is fascinated by the complexity of ecological communities. He will be examining the indirect effect of temperature on wild bee fitness through plant-pollinator phenological mismatch. To do so, he will be studying high-altitude wildflower and bee communities around the Rocky Mountain Biological Laboratory in Colorado. Gabriel likes baby goats, too (but who doesn’t?).

E-mail: mhotc015 “at”

Michelle is interested in bumble bees and the microbes that call their guts home. For her M.Sc. research she will investigate how pesticides alter the structure of bumble bee gut microbiomes, how a pesticide-exposed gut microbiome affects bumble bee fitness, and if pesticide-exposed microbiomes can recover after pesticide exposure.

Lydia is investigating the effects of drought on Colorado bees. In the past, she has worked on figuring out why solitary bee species nest when they do, and on which native and non-native plants are favoured by native bees in the city of Toronto.


Charlotte CahillCharlotte_Cahill
Honours student, 2018–19

Charlotte is interested in the factors that affect the phenology and fitness of solitary bees in alpine ecosystems. She will examine whether a non-native flower influences bees that specialize on plants in the daisy family (Asteraceae).


Marie-Ève CorbinMarie-Eve_Corbin
Honours student, 2018–19

Marie-Ève is interested in mason bee ecology and use of Osmia as orchard pollinators. Her honours project is looking at whether availability of nesting habitat predicts local abundance of Osmia bees.



Genevieve GeorgeGenna_George
Honours student, 2018–19

Genna is interested in how geographic information systems can be used in an ecological context. Her honours project uses GIS to examine how bee diversity changes across spatial scales in agroecosystems.



Leo GutierrezLeo Gutierrez
Honours student, 2018–19

Leo is finishing up his undergrad (Specialization in Biology) at the University of Ottawa. He will be working to extend our knowledge of the cavity-nesting Hymenoptera of the Yukon.
