Introduction
I am a community and ecosystem ecologist studying wetlands and floodplain ecosystems. My research projects include studies on ecosystems and landscape restoration and management with special focus on dynamics and functionality of natural and anthropogenic ecosystems, conservation status assessment, bioindication and control of invasive species. I am mostly an experimental ecologist that employs field, lab meso-and micro-cosm studies. I’m also interesting in environmental and rural law.

Conference Paper
Stormwaters in urban catchments are known to be contaminated with fine particles, trace metals, nutrients, hydrocarbons, etc., which are a source of environmental degradation. Yet, the Water Framework Directive (2000/60/CE) imposes to meet a “good status” for every water body in Europe. That is why the city of Strasbourg (Eastern France) has built...
Conference Paper
Full-text available
The main goal of the Water Framework Directive (2000/60/CE) is the achievement of a “good status” for every water body in Europe. In this purpose, the city of Strasbourg (Eastern France) has built in 2012 three stormwater constructed wetlands (SCW) between the outflow of three urban residential catchments and the Ostwaldergraben, a small urban rive...
Conference Paper
En milieu urbain, les rejets urbains par temps de pluie (RUTP) se sont mués en un véritable enjeu d’urbanisme. Dans cette optique, de nombreuses communes développent des réseaux décentralisés de gestion des RUTP appelés techniques alternatives (TA). L’Eurométropole de Strasbourg (EMS) a lancé en 2011 la construction de TA de type zones humides arti...
Conference Paper
En milieu urbain, l’imperméabilisation de la plupart des surfaces empêche les eaux pluviales (EP) de s’infiltrer à leur arrivée au sol. De plus, l’urbanisation croissante rend parfois obsolètes certains réseaux unitaires qui ont tendance à trop solliciter les déversoirs d’orages lors d’événements pluvieux. C’est ainsi que les rejets urbains par tem...

In Europe, large rivers have been greatly impacted by engineering and hydraulic works. The Upper Rhine channelization has notably led to a disconnection between the main channel and its floodplain and side channels. Between 1998 and 2006, unprecedented restoration projects led to the reconnection of nine Rhine side channels to the main channel or t...
Article
The role of within-species genetic variability and ecotypes has been poorly documented in research on water bioindication. Some studies already show that macrophytes could present genetic lineages with different optima for specific water parameters. In the present study, we tested this assumption on Potamogeton coloratus Hornem., a macrophyte descr...
