Les Aires Marines Protégées (AMPs) sont reconnues comme des outils efficaces de conservation et de gestion des ressources. L'efficacité des AMPs, définie comme le degré d'accomplissement de leurs objectifs, est très variable. Certaines caractéristiques des AMPs (âge) expliquent une partie de cette variabilité, mais une autre partie reste encore inexpliquée. En appliquant la Science de l’Organisation (OS, discipline qui étudie l’organisation) aux AMPs, d'autres facteurs qui affectent l'efficacité...

In the Arctic, shallow sea-floor communities have been documented to shift abruptly from an invertebrate-dominated state to a state with high macroalgal abundance. Climate warming, resulting in increased water temperatures and decreased sea ice cover, could trigger such regime shifts in benthic ecosystems, but the underlying mechanisms are not clear. To gain a better understanding, a mechanistic model of algal growth and interspecific competition was applied in two marine ecosystems in northwest...

Exposure to contaminants, such as Persistent Organic Pollutants (POPs), is currently considered a serious anthropogenic threat to marine predators and their food webs. Exposure to contaminants by marine wildlife is mainly related to their trophic ecology, distribution and movements. However, the contribution of these biological features to pollutant levels remains poorly understood in most marine predators, including seabirds. New methodologies, including dietary and geographic tracers, such as ...

Gobies (Gobiidae, Actinopterygii) are small, predominantly cryptic, marine, brackish and freshwater fishes. They abundantly inhabit coastal waters, although their occurrence is far from being mapped due to their inconspicity, often hidden lifestyle and a lack of commercial use. Information about distribution of many species is therefore still rather poor. Many species are known only from a few locations scattered throughout the Mediterranean Sea and the Atlantic. This suggests that most species ...
