MODECO. A Modelife colloquium

Cette journée est dédiée aux recherches impliquant la modélisation de dynamiques écologiques, à différentes échelles et pour différents organismes (plantes, insectes, poissons, plankton...), afin de répondre à des questions d'adaptation aux changements globaux, d'évolution ou encore de conservation.

Date : mardi 16 juillet

Lieu : campus de Valrose, Nice (théâtre du Grand Château)

Horaires : 9h - 17h.

Inscription gratuite, mais obligatoire (pour les pauses cafés et le buffet du midi)

Keynote Speakers

Vasilis Dakos (CNRS, Montpellier) "Resilience, Tipping points, and Evolution"

Evidence is increasing that large scale abrupt changes in ecosystems, fisheries, oceanic circulation patterns, or even human physiology are examples of catastrophic transitions between different dynamical states typically referred to as tipping points. Recent theoretical findings suggest that distinct properties tend to rule system dynamics prior to such transitions. When quantified, these properties may be even used as indicators of loss of resilience for these systems. In this talk, I will present how we can quantify resilience and detect tipping points using examples from ecology and the climate. Lastly, I will outline some ideas on how we can expand such approaches to better understand tipping point responses in a changing but evolving world.
Vasilis Dakos is broadly interested in ecological stability, tipping points, and how eco-evolutionary feedbacks may affect ecosystem resilience under global change.

 

Damien Eveillard (Université de Nantes) "Investigating microbial ecosystems: a computational journey from co-occurrence to metabolic networks"

Ecosystems are today analyzed by emphasizing their genomic composition. However, understanding interactions within communities to predict diversity on the basis of physicochemical parameters is a fundamental pursuit of microbial ecology that still eludes us. Such a task must be achieved by dedicated computational approaches inspired by Systems Biology. First, we will present a network analysis of the global ocean to improve understandings of a biological process. Second, we will describe how to integrate heterogeneous omics knowledge to emphasize functional units at the community level. Finally, we will illustrate a quantitative modeling that considers genome-scale knowledge to predict community behaviors.

En plus des deux conférences keynote, des chercheurs et doctorants de différents laboratoires de la région (LOV de Villefranche, INRA de Sophia Antipolis, ECOMERS de Valrose, INRIA de Sophia) présenteront leurs travaux au cours de la journée.
