Elise Deschenes

Student Speaker | Étudiant.e
La composition des espèces dans les communautés varie dans le temps et l’espace le long de gradients environnementaux (climat, perturbation, etc.). Nonobstant, plusieurs questions demeurent quant aux mécanismes expliquant les assemblages d’espèces, la coexistence des espèces... Read More →

Ella Martin

Student Speaker | Étudiant.e
Biotic interactions are predicted to be stronger towards the tropics due to latitudinal gradients in climate, productivity, and biodiversity. This hypothesis is often tested using seed predation as a measure of biotic interactions, and previous studies have supported the prediction... Read More →

Lotte Skovmand Jensen

Student Speaker | Étudiant.e
Plants are constantly defending themselves against herbivory and coping with their surroundings. When we think of a defense, thorns and spines come to mind. However, a diverse system of chemical compounds is also produced by the plants to survive in their environment. These compounds... Read More →

Aliénor Stahl

Student Speaker | Étudiant.e
I will be presenting the main goals of the first two chapters of my PhD. They focus on predicting the abundance of lake fish from food web structure. The first chapter is a proof-of-concept and the second one is an application to a known dataset, combined with a comparison of several... Read More →

Antonio Rodriguez-Campbell

Student Speaker | Étudiant.e
Darwin theorized that species interaction intensity increases towards the Tropics and lowland ecosystems, leading to important implications for conservation under climate change. These biotic interactions are often measured with predation rates on seeds and occasionally invertebrates... Read More →

Dominique Caron

Student Speaker | Étudiant.e
Le maintien de l’intégrité des écosystèmes passe par la protection des organismes vivants, mais également le réseau d’interactions reliant ceux-ci. Malheureusement, les données d’interactions entre espèces sont souvent rares, biaisées et hautement incertaines. Il est... Read More →
