Événement de mortalité massive chez les gorgones : conséquence d’une vague de chaleur exceptionnelle
From
medpan
L’été 2022 a été particulièrement mortel pour les gorgones pourpres (Paramuricea clavata) en Méditerranée Nord-Occidentale. En effet, des températures exceptionnelles ont été enregistrées dans les eaux méditerranéennes françaises, impactant l’écosystème de manière irrémédiable.

The establishment of multiple zones offering different protection levels within a Marine Protected Area (MPA) can minimize social conflicts while maintaining associated biodiversity benefits such as fish population replenishment. Parrotfishes are among one of the most ecologically important reef fishes; yet extremely overexploited worldwide. In this context, well-designed priority management areas allowing no fishing activity (no-take zones) could help recover fish species, such as parrotfishes, through a MPA zoning process.

Human visitation disrupts natural determinants of breeding seabird communities on coral reef islands
Abstract: Coral Reef Islands (CRIs) support key colonies of tropical seabirds, whose long-term sustainability is under growing threat from climate change and small-scale, island-specific pressures such as invasive species or human disturbance. Unlike most compartments of reef ecosystems, CRI seabirds have been poorly studied from a biogeographical perspective, which questions the relevance of existing conservation policies. Here, we investigate the effects of ecological, geographical and anthropogenic drivers on the diversity and abundance of CRI seabird communities, using survey data acquired over the 2000–2023 period in 100 CRIs of New Caledonia, South-western Pacific.
