Under the influence of both environmental perturbations (e.g., wind-driven processes, freshwater influence, unbalanced nutrient levels) and biotic interactions (e.g., competition, predation, facilitation), phytoplankton species exhibited specific survival strategies such as investment on growth, adaptation and tolerance of species to environmental stresses, silicification and resource specialization. These strategies have led to more speciose communities, higher productivity, functional redundancy and stability in the last decade. Our results revealed that the unbalanced nutrient reduction facilitated\ Phaeocystis\ blooms and that anthropogenic climate warming and nitrate reduction may threaten the diatom communities of the eastern English Channel in a near future. Our results provide strong support for biogeographical historical and niche-based processes in structuring the phytoplankton community in this temperate region.

Because of their location, coastal ecosystems are directly influenced by human activities.

Twelve sampling stations distributed in eight ecosystems of Western Europe were monitored during two decades for physico-biogeochemical parameters (temperature, salinity, concentrations of dissolved oxygen, nutrients and particulate material). The study encompasses a large diversity of temperate coastal ecosystems regarding geomorphology, trophic status, tidal regime, river influence, turbidity, and so on. Time-series analysis coupled with standardised 3-mode Principal Component Analyses, Partial Triadic Analyses and correlations were used to assess bi-decadal variability and ecosystems trajectories, and to detect the large-scale, regional and local drivers.

The\ bi-decadal changes are related to changes in large-scale and regional climate; detected through proxies of temperature and atmospheric\ circulation, as well as through river\ discharge. Ecosystem trajectories usually move towards an increase in temperature, salinity and/or a decrease in chlorophyll-a, nutrients and particulate matter. However, the magnitude of change, the year-to-year variability and the sensitivity to the 2001 and 2005 changes vary among the ecosystems.

Extreme events such as heat waves have increased in frequency and duration over the last decades. Under future climate scenarios, these discrete climatic events are expected to become even more recurrent and severe. Heat waves are particularly important on rocky intertidal shores, one of the most thermally variable and stressful habitats on the planet. Intertidal mussels, such as the blue mussel Mytilus edulis, are ecosystem engineers of global ecological and economic importance, that occasionally suffer mass mortalities. This study investigates the potential causes and consequences of a mass mortality event of M. edulis that occurred along the French coast of the eastern English Channel in summer 2018. We used an integrative, climatological and ecophysiological methodology based on three complementary approaches. We first showed that the observed mass mortality (representing 49 to 59\% of the annual commercial value of local recreational and professional fisheries combined) occurred under relatively moderate heat wave conditions. This result indicates that M. edulis body temperature is controlled by non-climatic heat sources instead of climatic heat sources, as previously reported for intertidal gastropods. Using biomimetic loggers (i.e. {\textquoteright}robomussels{\textquoteright}), we identified four periods of 5 to 6 consecutive days when M. edulis body temperatures consistently reached more than 30 {\textdegree}C, and occasionally more than 35 {\textdegree}C and even more than 40 {\textdegree}C. We subsequently reproduced these body temperature patterns in the laboratory to infer M. edulis thermal tolerance under conditions of repeated heat stress. We found that thermal tolerance consistently decreased with the number of successive daily exposures. These results are discussed in the context of an era of global change where heat events are expected to increase in intensity and frequency, especially in the eastern English Channel where the low frequency of commercially exploitable mussels already questions both their ecological and commercial sustainability.
