Ce premier inventaire des poissons marins du sommet du Mont La Pérouse a été réalisé sur la base de films et de photographies effectués par des plongeurs, équipés de recycleurs, opérant entre-60 m et-140 m de profondeur. Un total de 147 espèces appartenant à 36 familles a ainsi été recensé. La structure du peuple-ment est surtout marquée par de nom...

The choice of ecological monitoring methods and descriptors determines the effectiveness of a program designed to assess the state of coral reef ecosystems. Here, we comparer the relative performance of the traditional Line Intercept Transect (LIT) method with three methods derived from underwater photogrammetry: LIT on orthomosaics, photoquadrats...

Understanding colonization of new habitats and ecological successions is key to ecosystem conservation. However, studies on primary successions are scarce for reef-building corals, due to the rarity of newly formed substratum and the long-term monitoring efforts required for their long life cycle and slow growth rate. We analysed data describing th...

Structural complexity plays a key role in the functioning of coral reef ecosystems. Reef-building corals are major contributors to this complexity, providing shelter and food for numerous invertebrates and fish species. Both structural complexity and shelter capacity of reefscapes are determined by several components such as spurs and grooves, slop...

Seamounts are potential reservoirs for marine biodiversity and actually studied for large sea animals. Here we provide information regarding benthic dinoflagellates commonly found in shallow waters, that occur in -61 to -120m depth.
Article
Ostreopsis mascarenensis is a toxic dinoflagellate described from the Indian Ocean based only on morphology, without molecular data. Morphological features of Ostreopsis have poor taxonomic value, and the addition of genetic data would ensure correct species identification. The present study reinvestigated field samples from Réunion Island and the...

Climate change constitutes a new threat to the sustainability of coral ecosystems. The vulnerability of a coral ecosystem to climate-related hazards can greatly increase when it suffers from chronic anthropogenic disturbances (wastewater discharges, eutrophication). These indeed reduce the ability of coral reefs to withstand these hazards (resistan...

Article
Coral reef degradation due to environmental change, including anthropogenic disturbances, is a major concern worldwide. Detecting and assessing both temporal and spatial changes in benthic cover is a crucial requirement to inform policy makers and guide conservation measures. Here, we introduce a spatial approach based on high resolution multispect...
Chapter
Coping with climate change is a crucial issue for coral reef monitoring. This chapter advocates a holistic approach based on a Driver–Pressure–State–Impact–Response (DPSIR) model in order to build a dashboard of indicators. Coral reefs should be studied as a social ecological system, which means to (a) monitor the ecosystem and the socio-system in...
Article
Four amateur naturalists and underwater photographers established sixty first records and discovered three species probably new to science at Reunion Island (Indian Ocean) between January 2010 and January 2016, although the marine environment of this island has been studied for some forty years by professional scientists. These results were achieve...

Recent volcanic lava flows extending into the ocean represent an ideal opportunity to study the long-term successional development of marine floral assemblages on the bare new substratum. We describe the floral assemblages of nine lava flows of different ages (prehistoric to 2007) at Piton de la Fournaise (Reunion Island, Indian Ocean) based on a s...

Recent surveys conducted on Reunion Island coral reefs revealed an atypical manifestation of black band disease on the main framework building coral, Porites lutea. This BBD manifestation (PorBBD) presented a thick lighter-colored band, which preceded the typical BBD lesion. Whilst BBD aetiology has been intensively described worldwide, it remains...

Benthic surveys were conducted on submerged lava beds of varying age off the east coast of Reunion in 2011. Scuba-mediated collecting and photography was undertaken within depth zones at 10 sites on four pre-1977 lava beds and those formed in 1977, 2002, 2004 and 2007. Sponges (23 species in 18 genera and 17 families), octocorals (20 species in 9 g...
