Tonia De Bellis

Tonia De Bellis

(Visiting Researcher)

Professor (2005 – present) – Dawson College
PhD (2002 – 2007) – Concordia University

Tonia is working on a project exploring mutualistic interactions between plants and mycorrhizal fungi in the context of biological invasions



Shaun Turney

Shaun Turney

(FRQNT Postdoc Fellow)

PhD (2014-2018) – McGill University
MSc (2012-2014) –  McGill University
BSc Honours (2008-2012) – Carleton University

Shaun is a postdoc and is exploring the determinants of community structure in ant communities. He is using existing data on the composition of ant communities in multiple regions of the world, combined with morphological data, to ask questions about the processes governing community assembly

(NSERC CREATE Scholarship; co-supervised by Tanya Handa)

PhD (2016-present) – Concordia University
MSc (2014-2016) – Universidade Estadual de Campinas
BSc Honours(2007-2012) – Universidad de El Salvador

Javier is interested in how the functional structure of ant communities varies across environmental gradients and how ant functional diversity can structure arthropod communities and influence ecosystem processes

Serena Sinno

MSc (2019-present) – Concordia University
BSc Honours (2018-2019) – Concordia University

Serena is working in the lab of Carly Ziter and in collaboration with our lab on a project related to plant-pollinator interaction in urban ecosystems.


Maggie 2019

Maggie Blondeau 

BSc Honours (2019-present) – Concordia University

Maggie studies the relationship between odonate immune response and rates of parasitism, as well as how those dynamics play out along broad-scale environmental gradients

Lab Alumni


Kelly MacDonald (CUSR Award)
BSc Honours (2018-2019) – Kelly studied the effects of fish predation on the community structure and size distribution of dragonfly larvae. She is now an MSc student with Shawn Leroux at Memorial University

Frédérique La Richelière (co-supervised by Ehab Abouheif)
MSc (2016-2018) – Frédérique investigated the evolutionary and ecological trends that lead to caste development in ant species on a global scale

François Brassard
MSc (2016-2018) – François worked on caste-specific determinants of morphological variation along abiotic gradients in North American ants

Sarah Ouimette (NSERC PGS M, co-supervised by Piero Calosi)
Msc (2016-2018) – Sarah worked on life-stage related differences in thermal tolerance of odonates and how they relate to their geographic distributions

Sergio Vega (MITACS Scholarship)
MSc (2016-2018) – Sergio’s research aimed to determine how land use affects native bee communities in Quebec blueberry fields

Katherine Hébert (NSERC PGS M, co-supervised by Virginie Millien)
MSc (2015 – 2017); BSc Honours (2012 – 2015) – Katherine investigated the mechanisms underlying the assembly of insular mammal communities across the globe. She is now doing a PhD with Dominique Gravel at University of Sherbrooke.

Daniella LoScerbo (NSERC USRA)
BSc Honours (2016-2017) – Daniella studied the effects of mite parasitism on odonate community structure

Julie Arrowsmith
MSc (2014 – 2016) – Julie worked on the maintenance of regional diversity in Odonates. Specifically, she is interested in how habitat associations might mediate the relative importance of stochastic and deterministic processes in driving among-community variation in species composition.

Sean-Anthony Di Paolo 
BSc (2012 – 2016) – Sean asked whether spatial variation in the community structure of odonate adults can be predicted by that of larvae

Victoria Pompa
BSc Honours (2012 – 2016) – Victoria was interested in comparing the functional diversity of endomycorrhizal fungi on native and invasive Maple trees.
