Pools of aquatic plants and benthic invertebrates were collected along with 47 individuals from three cyprinid fish species (Barbus barbus, Gobio gobio, Rutilus rutilus) at a site in the Rhone River (France). Carbon and nitrogen isotopic ratios (delta C-13 ...
Urban stormwater discharges during wet weather has always been a sensitive issue to deal with. By inducing combined sewer overflows, substantial impacts on receiving water are commonly feared. Aware of this problematic situation, the VSA already created th ...
The bioavailability of metals was estimated in three river sediments (Sens,e, Scarpe, and DeA >> le Rivers) impacted by different levels of Cu, Cd, Pb, and Zn (Northern France). For that, a combination of geochemistry and biological responses (bacteria and ...
Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial homeost ...
Dispersion of larval offspring is of fundamental ecological importance to sessile marine organisms. Photosymbiotic planulae emitted by many reef-forming corals may travel over large distances before settling to form a new colony. It is not clear whether th ...
Sediments are an essential component of fluvial ecosystems. They are also quite often a cause of disturbance for fluvial works, such as dams or locks. In order to manage these disturbances without causing adverse impacts downstream, managers should have in ...
Mitochondria are the main producers of ATP, the energy currency of the cell, and they perform a wide array of other fundamental functions. These organelles are essential not only for cellular metabolism, but also for organismal physiology and lifespan. A r ...
The roundworm Caenorhabditis elegans (C. elegans) is a powerful model organism for addressing fundamental biological questions related to human disease and aging. Its life cycle consists of an embryo stage, four larval stages that can be clearly distinguis ...
The Drosophila larval nervous system is radically restructured during metamorphosis to produce adult specific neural circuits and behaviors. Genesis of new neurons, death of larval neurons and remodeling of those neurons that persistent collectively act to ...
The occurrence of chronic or delayed toxicity resulting from the exposure to sublethal chemical concentrations is an increasing concern in environmental risk assessment. The Fish Embryo Toxicity (FET) test with zebrafish provides a reliable prediction of a ...
