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).

Predator-mediated effects of herbivores on tundra nesting birds
Supervisor(s): Joël Bêty , Dominique Gravel

Research project

Global changes, particularly pronounced in the Arctic, threaten biodiversity and transform Arctic terrestrial communities. One of these transformations, observed at the circumpolar scale, is the explosion of geese populations. As geese reach record population levels, lemming cycles are fading in several parts of the Arctic and shorebird populations are experiencing marked declines at the circumpolar scale. Geese, lemmings and shorebirds share common predators and are therefore closely linked through indirect trophic interactions. Shared predation can affect species abundance and coexistence at the community level through a variety of indirect effects (e.g. apparent mutualism, apparent competition). Despite a large number of studies on trophic interactions involving shorebirds, predator-mediated effects of herbivores on shorebirds remain poorly understood. By adopting a multi-sites approach combined with long-term ecosystem monitoring, this thesis addresses predator-prey interactions and their potential indirect impact on shorebirds experiencing significant population declines. The main objective of my project is to determine the role of indirect trophic interactions on Arctic shorebirds. This project combines a theoretical and empirical approach in collaboration with researchers working in various sites at a circumpolar scale (Canada, Norway and Greenland). This project also relies on long-term ecosystem monitoring datas (>25 years) from Bylot Island (NU). Understanding indirect interactions is necessary to maintain the ecological integrity of protected ecosystems and to preserve Arctic biodiversity. How species interact have fascinated and continue to generate great interest among the scientific community and the relative simplicity of the Arctic vertebrate community provides an ideal theoretical framework to address these questions.

Effect of temperature on trophic cascades
Supervisor(s): Dominique Gravel

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
Supervisor(s): Dominique Gravel

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.

Macro-evolution of food webs on Galapagos Islands
Supervisor(s): Dominique Gravel , Christine Parent

Research project

The theory of island biogeography, initially elaborated by MacArthur and Wilson (1963), inspired many scientists on their research on population dynamics and insular community assembly. What began as a pretty simple theory putting in relation immigration, extinction and distance between the island and the mainland to explain species richness of an island rapidely got adapted by a few reserchers to try and obtain a macroevolution model on islands. However,whether it is by immigration, speciation or extinction, the variation of species composition always modifies, with more or less impact, community assembly and the species distribution on a given territory. Therefore, an important question to ask is how the already existing foodweb networks react to these new species arrivals or extinctions. How did these networks evolved to what we know today, and how will they react in the futur to the modifications caused by the global warming ? Given it’s rich historical character for the study of evolution, the Galapagos Islands archipelago will be used as my experimental playground since there is an important documentation existing on the species occurences on each island. With these data, the network structure will be infered, and put in relation with the age of the island to try to determine the influence of the evolutinary period on the network complexity.

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 forest 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.
