Madelaine Anderson (Ph.D. Student)

Broadly, I am interested in how plant communities and landscapes are impacted by global change. Growing up, I spent all my summers in northern Canada, which inspired curiosity about and passion for northern ecosystems. The Arctic tundra biome is changing quickly with major implications on biodiversity, climate, and humans. My doctoral research is situated within the Arctic portion of the Canadian Airborne Biodiversity Observatory (CABO) project. Working with CABO and Team Shrub, led by Isla Myers-Smith and based out of the University of Edinburgh, I will explore biodiversity change in the tundra biome using remote sensing approaches and field-based surveys. I will ask questions about linking tundra plant spectral signatures to tundra plant phenology, plant traits and biodiversity.

Tadhg Carroll (Postdoc, Leverhulme Centre for Anthropocene Biodiversity, co-supervised with Maria Dornelas & Chris Thomas)

I am interested in all aspects of Ecology, but my work has focused to date on Community Ecology. My research at the Leverhulme Centre for Anthropocene Biodiversity focuses primarily on investigating biodiversity change in contemporary ecological assemblages. Biodiversity is complex, and needs to be viewed in many different ways in order to understand how it has changed in the past, or to have any hope of predicting future trajectories. I’m keen to uncover processes underlying biodiversity change, as well as documenting various aspects of empirical trends over time. Current lines of research include attempts to understand adaptive dynamics in ecological communities, and if and how rare species become common and common species become rare. I also have a deep interest, and gradually growing skillset, in Applied Bayesian Statistics and how such techniques can be used to tease knowledge out from nature.

Charlotte Brown (Postdoc)

I am a plant community ecologist who uses a blend of field observations and experiments to investigate the factors underlying the wide-ranging responses of species to environmental shifts and global change. I am particularly interested in how this variation in species responses can scale up to impact larger-scale community and ecosystem dynamics, particularly species interactions. I am driven by overarching concepts rather than being confined to particular ecosystems, leading me to work in a diverse range of environments such as grasslands, deserts, and forests .

During my postdoc at the Université de Sherbrooke, I am examining the climatic drivers of species' phenological shifts and how variation in species sensitivities, both in magnitude and to particular climatic events, impact current and future species interactions, flowering synchrony, and overall community structure.

Najwa Houmam (M.Sc. Student)

Je suis intéressée par la biodiversité des plantes et comment les écosystèmes répondent aux changements climatiques, pour mieux comprendre comment ces changements peuvent affecter le calendrier phénologique. Pour ma maîtrise, je vais effectuer un travail de terrain dans le Parc national du Mont Mégantic, Québec. Je vais utiliser la photographie en temps réel et autres méthodes pour répondre aux questions suivantes : (i) Comment les changements climatiques peuvent impacter la phénologie des arbres à travers le temps et l’espace? (ii) Comment les relations phénologie-climat varient-elles d'une espèce à l'autre et d'un environnement à l'autre?

I have broad interests in plant biodiversity and how ecosystems respond to climate change, with a particular focus on the timing of biological events (phenology). For my Master's degree, I will conduct field work in Parc national du Mont Mégantic, Quebec. Using repeat photography and field validation, I will address the following questions: (i) What is the impact of climate change on tree leaf phenology over space and time? (ii) How do phenology-climate relationships vary across species and environments?




Anna Crofts (Ph.D. student)

I am a field ecologist, broadly interested in how plant abundance and distributions are changing in response to global change and, in turn, how these changes in plant community composition influence ecosystem properties. During my BSc, at the University of British Columbia, I was hired as an alpine ecologist research assistant which sparked my interest in plant ecology, specifically related to elevational gradients. My MSc, at Memorial University of Newfoundland and Labrador, examined how biotic interactions affect boreal conifer recruitment at alpine treeline.

In 2019, I began my PhD working as a part of the Canadian Airborne Biodiversity Observatory (CABO), an interdisciplinary research initiative aimed at examining major drivers of plant biodiversity across Canada through spectranomics. Spectranomics is a novel approach to quantifying plant taxanomic and functional diversity, which uses airborne hyperspectral images to identify plant species and quantify foliar traits. I will lead the field-based biodiversity survey in Parc national du Mont Mégantic, Québec. For my doctoral research, I ask: (i) can remotely-sensed, hyperspectral data quantify forest community properties, and in turn, (ii) how do forest community properties vary across climate (elevation) and resource extraction gradients?

Sabine St-Jean (M.Sc. Student)

Les changements climatiques ont le potentiel de désynchroniser les phénologies d’espèces interdépendantes, comme les plantes et leurs pollinisateurs. Fleurir plus tôt est souvent considéré comme un avantage en conférant une saison de croissance plus longue, mais peut aussi entraîner des coûts comme une insuffisance de pollinisateurs tôt au printemps. Les taux vitaux des plantes, par exemple la production de graines, pourraient s’en trouver affectés. Mon objectif est donc d’évaluer l’effet de la date de floraison des plantes printanières sur leur pollinisation et sur leur reproduction, tout en dressant le portrait de la biodiversité des pollinisateurs le long du gradient d’élévation du Mont-Mégantic.

 Climate change has the potential to alter the synchrony in the phenologies of interdependent species, like plants and their pollinators. Flowering earlier is often considered as an advantage by offering a longer growing season but may also entail costs such as insufficient pollination in early spring. Vital rates of plants, such as seed production, could be affected. Thus, my objective is to evaluate the effect of flowering dates of spring ephemerals on their pollination and on their reproduction, as well as to characterize the pollinator biodiversity along the altitudinal gradient on Mont Megantic

Guillaume Tougas (M.Sc. Student)

J'entame ma maitrise avec l'objectif de mieux comprendre les impacts des changements environnementaux sur nos forêts locales et de contribuer à la planification de la conservation des espèces végétales du Québec. La fréquence et l’intensité de certaines épidémies de pathogènes forestiers sont appelées à augmenter avec les variations dans le climat. Dans cet optique, j’étudierai notamment l'évolution de la maladie corticale du hêtre au parc national du Mont-Saint-Bruno par télédétection à partir d'imagerie hyper-spectrale aérienne. Ce projet est inclus dans CABO (Canadian Airborne Biodiversity Observatory). J’y utiliserai la technologie hyper-spectrale afin de tenter de détecter les stades de la maladie au sein des couronnes d’arbres individuels à partir de variations dans la composition chimique des feuilles.

The objectives of my master’s degree are to better understand climate change impacts on our local forests and to contribute to plant species’ conservation planning in Québec. The frequency and the intensity of many forest diseases are increase due to climate warming. With this in mind, I will study the progression of beech bark disease (BBD) in Mont-Saint-Bruno National Park using remote sensing with aerial hyperspectral imagery. This project is part of the Canadian Airborne Biodiversity Observatory (CABO). I will use hyperspectral technology in an attempt to detect the different BBD stages within the crowns of individual trees from variation in leaf chemical composition. 

Audrey Lafrenaye (Ph.D. student)

Depuis plusieurs années, je m’intéresse aux interactions entre les insectes et les plantes. Au cours de ma maîtrise et de mon parcours professionnel, j’ai concentré mes recherches sur le contrôle des ravageurs en agriculture. Pour mon projet de doctorat, qui a débuté en février 2024, je vais me pencher sur les interactions entre les plantes et leurs pollinisateurs le long du gradient altidudinal au Mont-Mégantic, Québec. Mon objectif principal est de mieux comprendre l'impact des changements climatiques sur le succès reproducteur des plantes ainsi que sur leurs pollinisateurs en milieu forestier. À travers mes travaux, j'espère apporter des contributions significatives à la prédiction des effets du réchauffement planétaire, afin d'orienter efficacement les efforts de conservation des écosystèmes forestiers.

For several years, I have been interested in interactions between insects and plants. During my master's degree and professional journey, I have focused my research on pest control in agriculture. For my doctoral project, which began in February 2024, I will investigate the interactions between plants and their pollinators along the altitudinal gradient at Mont-Mégantic, Quebec. My primary objective is to better understand the impact of climate change on the reproductive success of plants and their pollinators in forest environments. Through my work, I hope to make significant contributions to predicting the effects of global warming, in order to effectively guide efforts in conserving forest ecosystems.
