À l’ère de l’anthropocène, l’un des plus grands défis de la modélisation trophique appliquée au milieu marin est sa capacité à coupler les multiples effets issus à la fois du changement climatique et des activités anthropiques locales, notamment le développement de l’éolien en mer. L’enjeu majeur est de réaliser des scénarios pour caractériser le c...

Coastal ecosystems provide a wide range of valuable ecosystem services (ES) for human wellbeing. Such services depend on the functioning and structure of ecosystems. Unfortunately, these ecosystems are threatened by humans, directly impairing their ability to provide these services. In order to predict such changes, we used a food web model to fore...

Food webs are complex networks of both feeding (trophic) and non-trophic interactions among species from different functional groups (primary producers, plankton, benthos, fish, birds and mammals) in ecosystems. Therefore, holistic and integrative approaches are needed to assess the ecological status of food webs and ecosystems. This model-deriv...

This poster proposes a general methodological framework to quantify the supply of marine ecosystem services (ES) in the context of offshore wind farm (OWF) development. It also highlights the interests and challenges of applying trophic modeling to characterize the marine ES. Our results show that trophic modeling is an effective tool to characteri...

Coastal ecosystems are subjected to an increasing number of anthropogenic drivers, including marine renewable energies and climate change (CC). These drivers can interact in complex ways, which may lead to cumulative effects (CEs) whose potential consequences on the ecosystems need to be addressed. We used a holistic approach—ecological network ana...

Integrative and spatialized tools for studying the effects of a wide variety of ecosystem drivers are needed to implement ecosystem-based management and marine spatial planning. We developed a tool for analyzing the direct and indirect effects of anthropic activities on the structure and functioning of coastal and marine ecosystems. Using innovativ...

Avec l’accroissement de la population humaine sur Terre, le nombre et l’intensité des activités humaines sur les littoraux ne cessent d’augmenter. Ces activités peuvent avoir des effets importants sur l’environnement et sur les écosystèmes. De plus, la grande diversité de ces activités sur les côtes fait que les écosystèmes côtiers sont presque tou...

We introduce a methodology to study the possible matter flows of an ecosystem defined by observational biomass data and realistic biological constraints. The flows belong to a polyhedron in a multi dimensional space that may make statistical exploration difficult in practice; instead, we propose to solve a convex optimization problem. Seven criteri...

In this poster we detail the use of ecological indicators (ENA indices) to study cumulative effects on the ecosystem functioning and on an emerging property: ecological resilience. This was made by modeling the food web of the extended Bay of Seine in the English Channel using Ecospace and by combining multiple approaches to simulate the potential...

Climate change is already known to cause irreversible impacts on ecosystems that are difficult to accurately predict due to the multiple scales at which it will interact. Predictions at the community level are mainly focused on the future distribution of marine species biomass using ecological niche modelling, which requires extensive efforts conce...

In an increasingly anthropogenic world, the scientific community and managers have to take interactions between the drivers of ecosystems into consideration. Tools like ecological network analysis (ENA) indices offer the opportunity to study those interactions at the ecosystem level. However, ENA indices have never been used to test the incidence o...

Species Distribution Models (SDMs) are useful tools to project potential future species distributions under climate change scenarios. Despite the ability to run SDMs in recent and reliable tools, there are some misuses and proxies that are widely practiced and rarely addressed together, particularly when dealing with marine species. In this paper,...

Environmental impact assessment (EIA) studies for offshore wind farm projects endeavour to consider the sensitivity of ecological compartments (benthos, fish, birds and marine mammals) to potential pressures/changes occurring in the ecosystem structure and functioning. EIA is expected to be conducted considering an integrated ecosystem approach, wh...

Les études d’impact environnemental menées en amont des projets éoliens offshores considèrent chaque compartiment de manière individuelle, et non pas l’écosystème dans son ensemble. La compréhension des liens trophiques et l’appréhension de l’écosystème de manière holistique est pourtant un enjeu important rapporté par les politiques publiques tell...
