Long‐term experimental drought alters floral scent and pollinator visits in a Mediterranean plant community despite overall limited impacts on plant phenotype and reproduction

Journal of Ecology, Volume 110, Issue 11, Page 2628-2648, November 2022., 2022
In the Mediterranean Basin, climate change is causing an intensification of drought intensity and frequency. Our community‐level in situ measures showed that drought altered floral scent with changes in plant–pollinator interactions and limited impacts on plant reproduction. We discuss why the context of our study—an exceptionally wet year—may have led

Climate Change and Weather Extremes in the Eastern Mediterranean and Middle East

Reviews of Geophysics, Volume 60, Issue 3, September 2022., 2022
Abstract Observation‐based and modeling studies have identified the Eastern Mediterranean and Middle East (EMME) region as a prominent climate change hotspot. While several initiatives have addressed the impacts of climate change in parts of the EMME, here we present an updated assessment, covering a wide range of timescales, phenomena and future ...

Sensitivity to the sources of uncertainties in the modeling of atmospheric CO₂ concentration within and in the vicinity of Paris [PDF]

Atmospheric Chemistry and Physics, 2021
The top-down atmospheric inversion method that couples atmospheric CO2 observations with an atmospheric transport model has been used extensively to quantify CO2 emissions from cities. However, the potential of the method is limited by several sources of

Analysis of atmospheric CO2 variability in the Marseille city area and the north-west Mediterranean basin at different time scales

Atmospheric Environment: X, 2023
This study presents the first analysis of the variability of atmospheric CO2 in the area of the Marseille city (France). It addresses the role of anthropogenic emissions, natural fluxes and atmospheric boundary layer height (ABLH) dynamics on CO2 ...
