I regard myself as a theoretician/data scientist motivated by a strong desire to apply the results of abstract investigations to tangible challenges such as the impact of land-use change on ecological networks.
During my PhD, I investigated the relationship between biotic interactions and species co-occurrence. Species's range limits are indeed not only affected by abiotic factors (such as precipitations and temperature), but they also are determined by the biological context. Although this was first suggested years ago, researchers are still struggling to find adequate approaches that appropriately include all of these factors which are key towards accurate predictions of tomorrow's biodiversity. I have found some promising research avenues to elucidate the conditions under which biotic factors cannot be neglected to predict species' distribution. In the post-doctoral project I have started in June of 2017, I am striving to apply the results of my PhD on the fish communities of the Ontario's lakes.

2019-04-01  | The inherent multidimensionality of temporal variability: How common and rare species shape stability patterns Jean-François Arnoldi, Michel Loreau, Bart Haegeman 10.1101/431296 Recommended by Kevin Cazelles and Kevin Shear McCann based on reviews by Frederic Barraquand and 1 anonymous reviewer Diversity-Stability and the Structure of Perturbations In his 1972 paper “Will a Large Complex System Be Stable?” [1], May challenges the idea that large communities are more stable than small ones. This was the beginning of a fundamental debate that still structures an entire research area in ecology: the diversity-stability debate [2]. The most salient strength of May’s work was to use a mathematical argument to refute an idea based on the observations that simple communities are less stable than large ones. Using the formalism of dynamical... |
