Comparative phylogeography of the western Indian Ocean reef fauna 5
Borsa, Philippe; Durand, Jean-dominique; Chen, Wei-jen; Hubert, Nicolas; Muths, Delphine; Mou-tham, Gerard; Kulbicki, Michel.
Assessing patterns of connectivity at the community and population levels is relevant to marine resource management and conservation. The present study reviews this issue with a focus on the western Indian Ocean (WIO) biogeographic province. This part of the Indian Ocean holds more species than expected from current models of global reef fish species richness. In this study, checklists of reef fish species were examined to determine levels of endemism in each of 10 biogeographic provinces of the Indian Ocean. Results showed that the number of endemic species was higher in the WIO than in any other region of the Indian Ocean. Endemic species from the WIO on the average had a larger body size than elsewhere in the tropical Indian Ocean. This suggests an...

A DNA barcode reference library of French Polynesian shore fishes 5
Delrieu-trottin, Erwan; Williams, Jeffrey T.; Pitassy, Diane; Driskell, Amy; Hubert, Nicolas; Viviani, Jeremie; Cribb, Thomas H.; Espiau, Benoit; Galzin, Rene; Kulbicki, Michel; De Loma, Thierry Lison; Meyer, Christopher; Mourier, Johann; Mou-tham, Gerard; Parravicini, Valeriano; Plantard, Patrick; Sasal, Pierre; Siu, Gilles; Tolou, Nathalie; Veuille, Michel; Weigt, Lee; Planes, Serge.
The emergence of DNA barcoding and metabarcoding opened new ways to study biological diversity, however, the completion of DNA barcode libraries is fundamental for such approaches to succeed. This dataset is a DNA barcode reference library (fragment of Cytochrome Oxydase I gene) for 2,190 specimens representing at least 540 species of shore fishes collected over 10 years at 154 sites across the four volcanic archipelagos of French Polynesia; the Austral, Gambier, Marquesas and Society Islands, a 5,000,000 km(2) area. At present, 65% of the known shore fish species of these archipelagoes possess a DNA barcode associated with preserved, photographed, tissue sampled and cataloged specimens, and extensive collection locality data. This dataset represents one...

Remote High-Definition Rotating Video Enables Fast Spatial Survey of Marine Underwater Macrofauna and Habitats 5
Pelletier, Dominique; Leleu, Kevin; Mallet, Delphine; Mou-tham, Gerard; Herve, Gilles; Boureau, Matthieu; Guilpart, Nicolas.
Observing spatial and temporal variations of marine biodiversity from non-destructive techniques is central for understanding ecosystem resilience, and for monitoring and assessing conservation strategies, e.g. Marine Protected Areas. Observations are generally obtained through Underwater Visual Censuses (UVC) conducted by divers. The problems inherent to the presence of divers have been discussed in several papers. Video techniques are increasingly used for observing underwater macrofauna and habitat. Most video techniques that do not need the presence of a diver use baited remote systems. In this paper, we present an original video technique which relies on a remote unbaited rotating remote system including a high definition camera. The system is set on...

Comparison of visual census and high definition video transects for monitoring coral reef fish assemblages 5
Pelletier, Dominique; Leleu, Kevin; Mou-tham, Gerard; Guillemot, Nicolas; Chabanet, Pascale.
Monitoring fish and underwater habitats, particularly in and around marine protected areas (MPAs) requires non-destructive observation methods. This is generally achieved by divers conducting underwater visual censuses (UVC), but video-based techniques are now being used more often to observe underwater macrofauna and habitats. A comparison of these two techniques is relevant with the development of high-definition (HD) video, which constitutes a substantial improvement over previously available video resolutions at limited extra cost. We conducted a paired observation experiment involving both HD video and UVC in an MPA located in the New Caledonian lagoon, which is a highly diversified coral reef ecosystem. We compared three techniques for counting fish...
