peer reviewed / Pollution particularly affects coastal ecosystems due to their proximity to anthropic sources. Among those en- vironments, harbours are subjected to marine traffic but also to accidental and chronic pollution. These areas are thus exposed to complex mixtures of contaminants such as trace elements and organic contaminants which can i...
peer reviewed / Aegagropiles are conglomerations of fibre debris from Posidonia oceanica meadows that are frequently found along Medi- terranean beaches, but the plant organ from which these fibres arise remains unknown. In this study, a histological compari- son of P. oceanica organs from 3 shoots with the structure of aegagropile fibres showed th...
peer reviewed / Studies of fishway performance, at the multi-species level in large rivers, are scarce and this raises the question of the passage success of both endemic and exotic species in anthropised environments. The study was conducted in the downstream part of the River Meuse (average annual discharge = 400 m3.s-1) on a 13 km transect betwe...
peer reviewed / We report dissolved CO2, CH4 and N2O concentrations in two large East African Rift lakes, Edward (surface area 2,325 km2, average depth of 37 m) and George (surface area 273 km2, average depth of 2 m). Lake George showed modest seasonal and spatial variations, and lower partial pressure of CO2 (pCO2) (26±16 ppm, mean±standard deviat...
peer reviewed / Man-made persistent pollutants (such as PCBs, pesticides and trace metals) reach aquatic organisms through the food chains. Pollutants are ingested and assimilated by smaller organisms, and their concentration in tissues increases from prey to predators. Being at the top of the food chains, marine mammals accumulate some of the high...
peer reviewed / Among the most common contaminants in marine ecosystems, trace elements are recognized as serious pollutants. In Corsica (NW Mediterranean Sea), near the old asbestos mine at Canari, trace elements from the leaching of mine residues have been discharged into the sea for several decades. The aim of this study was to assess the levels...
peer reviewed / Marine mammals include toothed and baleen whales, as well as seals, sea lions, sea cows, sea otters and polar bears. They are adapted to an aquatic life in oceanic, coastal and riverine habitats. They range in size from sea otters to blue whales. The extreme diversity of marine mammals is related to their adaptations to different ha...
editorial reviewed / Mass bleaching events alter the ecological process of coral reefs while marine protected areas (MPAs) can increase the resilience of coral reef communities to natural disturbances, playing a role in sheltering biodiversity from climate-related impacts and in the recovery of corals from massive bleaching events. In Moorea Island...
peer reviewed / Among the different disturbances affecting coral reefs, climate change is expected to become the major cause of their degradation towards this century. In coral reefs, anomalously high sea temperatures are linked to coral bleaching events. Mass bleaching events alter the ecological process of coral reefs while marine protected areas...
