Harvesting effects on tropical invertebrate assemblages in New Caledonia

Despite the importance of invertebrate resources for Pacific coral reef islands, few studies have specifically addressed the effects of harvesting on invertebrate assemblages including targeted and non-targeted species. The impacts of recreational ha...

Evolution geochimique et exemple d'amenagement des mangroves au Senegal (Casamance)

The mangroves of Senegal are limited to the inlet of the Casamance - a river with very low discharge - and to the Sine-Saloum. The mineralogical and geochemical analysis of sediments (derived from 30 deep bore-holes) shows the thickness of the mangro...

Mining in New Caledonia : environmental stakes and restoration opportunities

New Caledonia is a widely recognised marine and terrestrial biodiversity hot spot. However, this unique environment is under increasing anthropogenic pressure. Major threats are related to land cover change and include fire, urban sprawling and minin...

Données économiques maritimes françaises 1998

The purpose of this book is to value the economic significance of marine-related activities in France. Each industrial, or public non-commercial, sector is characterized by key figures relating to annual turnover, value added, employment and budget. ...

Bathymay : la structure sous-marine de Mayotte révélée par l'imagerie multifaisceaux

La campagne Bathymay, effectuée en 2004 à bord du N/O Marion Dufresne 2 , a permis de réaliser le premier levé bathymétrique complet de la pente insulaire de Mayotte. L'analyse préliminaire de la morphologie révèle l'existence de nombreux can...

Fisheries in the Pacific : the challenges of governance and sustainability

"Fisheries in the Pacific : The Challenges of Governance and Sustainability" is a multidisciplinary book, which examines various aspects of coastal and oceanic fisheries in Pacific waters. These interrelated fisheries sectors are critical for regiona...

Considering reefscape configuration and composition in biophysical models advance seascape genetics

Previous seascape genetics studies have emphasized the role of ocean currents and geographic distances to explain the genetic structure of marine species, but the role of benthic habitat has been more rarely considered. Here, we compared the populati...

Contrasted ecological niches shape fungal and prokaryotic community structure in mangroves sediments

Mangroves are forest ecosystems located at the interface between land and sea where sediments presented a variety of contrasted environmental conditions (i.e. oxic/anoxic, non-sulfidic/sulfidic, organic matter content) providing an ideal ecosystem to...
