Meta-analysis of successes and failures in ecological restoration of terrestrial ecosystems
In our changing world, submitted to huge anthropic pressures, ecosystem protection needs new paradigms. Among them, ecological restoration is emerging, which aims at enhancing biodiversity and ecological services in response to human pressure. As usual in novel research areas, the information is dispersed, and there is a lack of synthesis of the data collected. The aim of my postdoctoral stay in the Instituto Pirenaico de Ecologia is to coordinate an international team/task for producing a critical meta-analysis on the real benefits provided by Ecological Restoration projects in terrestrial ecosystems according to the initial degradation and the type of restoration (biotic vs abiotic) implemented. I started this postdoctoral stay in November 2016. Step by step, and in order to avoid redundancy with recent meta-analyses, and based on the screening on > 2300 articles, my colleagues and I decided to focus this work on both the impact of the “initial degradation intensity” and the complexity of the restoration actions implemented on the recovery completeness of the ecosystem.
After a PhD focused on how to use ecological engineering tools in order to decontaminate waters contaminated by trace elements (Phytoremediation in Constructed wetlands of waters contaminated by trace elements, University of Bordeaux, France) I kept working on the general topic of eco(toxico)logy though a postdoctoral position at BIOGECO (Bordeaux, France), being funded by the city of Bordeaux. This job consists in providing innovative and sustainable tools for (phyto)managing contaminated soils (and waters) in the city of Bordeaux. In parallel, I worked on gentle remediation options (GRO) aiming at rehabilitate and restore contaminated terrestrial ecosystems (polluted by trace elements, Hydrocarbons, etc.). Recently, I focused my work more on ecological restoration actions, aiming at bringing back the (eco)systems to their initial trajectory after anthropic pressures/degradations. The meta-analysis started during my postdoctoral position at the IPE of Jaca is part of this line of investigation.
