Theoretical investigation on trees’ migration rates
Supervisor(s): Dominique Gravel, Isabelle Boulangeat & Nikolay Strigul

Research project

In the framework of forest dynamics, many studies showed that to understand species distribution, it is important to take into account biotic and abiotic conditions as well as dispersal phenomenon. We would like to understand what are the most important drivers determining tree's dispersal including inter/intra-species interactions and climatic conditions. Nowadays, models are wide-spread in ecology to investigate dispersion and species distribution. In this Ph.D we use the McKendrick-von Foerster equations that we have spatialised. These equations determine forest dynamics (growth, renewal, mortality and seed dispersal). The first three components are affected by light availability. It is determined through perfect plasticity approximation, a threshold equation from N. Strigul et. al. (2008). Dispersal is assessed thanks to a dispersal kernel. We expect that fecundity and long-dispersal distance (from the kernel) are the most influential parameters on migration rates. We also expect to extract some results from travelling waves, that are particular solutions. Eventually, we will investigate on a real case: sugar maple (Acer saccharum) and balsam fir (Abies balsamea).

Effect of temperature on trophic cascades

Research project

Spatial distribution of biodiversity always fascinated ecologists. What are the main drivers of species distribution and why is species richness peaking in the tropics? Understanding food webs dynamics is a key point in trying to clarify this question. Trophic cascade is a central feature of food webs and has been widely documented in diverse ecosystems. However, their strength can be highly variable and it seems that temperature plays a role in this variation by strengthening the top down effect of predators on primary producers. Temperature is an essential driver of many ecosystem processes over large biogeographical gradients and can affect food webs structure in many ways by impacting (1) organisms’ biological and chemical rates, (2) organisms’ body size and (3) species richness; and indirectly altering the strength of trophic interaction. The nature of the relationships between temperature, body size, metabolic rates and richness remains hazy and lead to conflicting results. We use a modelling approach to investigate the impact of temperature on trophic cascade through biological rates, body size and richness.

Evaluating the cumulative impacts of natural and anthropogenic stressors on the structure and function of the food web of the Estuary and Gulf of St.Lawrence
Supervisor(s): Philippe Archambault, Dominique Gravel

Research project

L’intensification de l’empreinte humaine dans l’estuaire et le golfe du Saint-Laurent (EGSL) impose une planification stratégique et systématique de l’utilisation et de l’exploitation des ressources marines. Pourtant, une évaluation systématique des impacts cumulés demeure absente de la littérature. Un nombre important d’activités historiques, actuelles et émergentes caractérisent l’utilisation humaine du Saint-Laurent. Ces activités imposent plusieurs stresseurs environnementaux affichant un chevauchement spatial croissant. Individuellement, ils peuvent affecter la structure et le fonctionnement des écosystèmes. Imposés simultanément, les stresseurs peuvent agir en synergie et entraîner des effets non-linéaires. Ces effets demeurent largement incompris et conséquemment ignorés lors d’évaluations d’impacts environnementaux, qui demeurent orientées sur des espèces ou secteurs uniques. Les effets non-linéaires peuvent s’exprimer selon divers mécanismes, notamment la propagation indirecte de perturbations engendrée par la complexité des interactions biotiques structurant les communautés. Nous suggérons ainsi qu’une compréhension de la structure des réseaux d’interactions biotiques est nécessaire à l’évaluation adéquate des impacts cumulés au sein des écosystèmes. L’objectif général de ma thèse sera d’évaluer les effets de multiples stresseurs sur les réseaux d’interactions biotiques. Les objectifs spécifiques seront 1) d’évaluer les impacts cumulés sur les écosystèmes de l’EGSL, 2) de caractériser la structure spatiale des réseaux d’interactions biotiques de l’ESGL et 3) d’évaluer les impacts cumulés sur les communautés de l’EGSL. Les résultats de cette thèse permettront d’approfondir les connaissances sur les impacts de multiples stresseurs sur les communautés, de fournir un outil performant d’évaluation des impacts cumulés et de favoriser une approche systématique et proactive de gestion des ressources naturelles.

Linking community ecology theory with new developments in statistical modelling

Research project

In recent years, there was an explosion in the development of statistical techniques especially designed to approach various problems in community ecology. These new techniques are often referred to as joint species distribution models. These developments came mainly from mathematicians and statisticians who have an interest in ecological problems but that rarely have formal training in ecology. For this reason, many of the techniques proposed until now make few links with the theories in community ecology. For my postdoctoral fellowship, I will develop the links that relates the theories in community ecology and joint species distribution models. By developing these links, it will become possible to highlight the shortcomings in joint species distribution models and thus direct the developments of novel statistical methods. In addition, a better understanding of the link between ecological theory and joint species distribution models will help ecologists better understand the direction that can be taken with these new technical developments to refine the knowledge in community ecology.

Integrative evaluation of forest biomass removals for bio-energy, on biodiversity and ecosystems functioning.
Supervisor(s): Dominique Gravel, Isabelle Aubin

Research project

Synthesizing the diversity of responses of the different organisms of a community into global patterns that capture the relevance of those changes to ecosystem processes is a major challenge in biodiversity science. One approach for capturing multiple taxa and their associated processes is to consider ecological communities as networks of interacting species and processes (Reiss et al. 2010). The goal of Idaline’s project is to develop a new multi-trophic way of assessment of community responses to disturbances. This method will be applied to the problematic of forest biomass removals in the context of bioenergy. In this project, we will first describe this ecological network using a theoretical model adapted to the context of biomass removal. To understand the food web functioning, a theoretical model of the soil food web will be created taking into account the vegetation, the fauna, and the microbes. The species composing the model will be chosen according to the species inventoried by the collaborators in the experimental site. One of the main problems in developing soil food webs model is to assess the interactions between the species, because we lack a lot of informations about species diet. That's why we will use, in an original and mechanistic way, species traits matching to infer the interactions. With this model we can do simulations of functional groups removals and calculate metrics that represent the network functions. We can then know what are the keystone species that maintain particular functions, or umbrella species on which numerous species depend. In the last chapter of this project, key taxa response, their interactions and their impacts on important ecosystem processes will be integrated within a response and effect traits framework. The theoretical knowledge developed in the 1st component will be used as framework to help understand patterns observed in the field.

Knowledge Transfer in Statistical Relational Learning with Applications to Theoretical Ecology
Supervisor(s): Dominique Gravel, Timothée Poisot

Research project

My thesis focuses on a problem called transfer learning, which in layman's terms could be described as the capacity to automatically transfer knowledge between different tasks. It comes naturally to us, e.g. we use what we learned for walking when learning to run, but almost all machine learning algorithms build models from nothing. It is especially important in statistical relational learning, where learning a model from data is hard, often impossible, due to the number of possibilities. I hope to apply these new techniques to ecology, which has struggled to find integrative (and predictive) models of biodiversity.

Diversity Stability relationship in forest ecosystems
Supervisor(s): Igor Drobyshev, Yves Bergeron, Dominique Gravel

Research project

Biodiversity has been shown to stabilize ecosystem productivity through time, suggesting it may be critical to ecosystems sustainability in the face of environmental fluctuations. Both theory and grassland experiments have suggested that the asynchrony of species response to environmental fluctuations was the primary mechanism underlying the stabilizing effect of diversity. However, the variability of response within species may modulate the stabilizing effect of the asynchrony of species response. My Ph.D. project aims to determine whether tree species diversity stabilizes the productivity of temperate and boreal forests of Eastern Canada. We are particularly interested in the mechanisms at the origin of the variability of individuals' response to environmental fluctuations and in the role of these mechanisms in the stabilizing effect of diversity. Individuals being not well defined in grassland plants, the variability of individuals' response to environmental fluctuations cannot be estimated in grassland communities. For this reason, we investigated the diversity stability relationship in forest ecosystems, where individuals (i.e. trees) are easily identifiable. Our work could help better understand the mechanisms underlying the stabilizing effect of diversity and thus could help implement adapted management strategies to increase ecosystems stability in the face of environmental fluctuations.

Metabolic response of pitcher plant (Sarracenia purpurea) bacterial communities from a latitudinal gradient when exposed to a temperature gradient
Supervisor(s): Dominique Gravel, Timothée Poisot

Research project

The impact of climate change on ecosystems is a concern of growing importance. Modifications in the global temperatures may influence species repartition by a translation of their ecological niche and cause a change in ecosystems’ structure. Temperature is an important aspect of ecological niche and affects the metabolism greatly. Consequently, in 2004, Brown et al. elaborated the metabolic theory of ecology (TME) which incorporate the concepts of metabolism, temperature ant body size together. Therefore, the purpose of this research is to attest the application of this theory on the metabolic response form of a community. Hence, different bacterial communities from pitcher plants (Sarracenia purpurea) were sampled along a latitudinal gradient et will be exposed to different temperatures. Their metabolism will be determined according to their maximal growth rate. The expected results are that each individual response will take the shape of a bell curve that will fit under an exponential curve. If the results are concluding, the TME could be a precious tool to anticipate ecosystems transformations, modifications in the services they provide us and could allow a better administration of them.

Integrating forest dynamic and management under climate change
Supervisor(s): Dominique Gravel, Robert Bradley

Research project

It is well known that climate change will modify the distribution of trees over the coming decades and many studies have already showed responses for some species. However, the potential of forest management to mitigate climate change impacts on forest dynamics remains poorly understood. The overall goal of my PhD is to develop a decision-make tool to improve management strategies that take climate change into account. I will build a model that represents forest dynamics at different spatial and temporal scales, and the effect of natural and anthropogenic disturbances (e.g. climate change, forest management). The model will be parametrized from a forest inventory database and we will focus on tracking uncertainty using Bayesian methods. By quantifying trees migration rate under climate change in different forest management scenarios, we expect to find a positive effect of forest management on accelerating forest migration towards the north. In addition, we expect a better understanding of the synergetic interactions between human actions and forest dynamics.
