In the context of coral reef decline, mesophotic coral ecosystems (MCEs, 30-150 m) offer hope for the recovery of degraded euphotic reefs. The Deep Reef Refuge Hypothesis (DRRH) postulates the potential of mesophotic reefs to reseed euphotic reefs. This h…

Foraging is a key function in the animal kingdom. Foraging in groups drives food patch discovery through social information transfer that maximizes an individual's foraging success through either cooperation or competition in response to congener presence…

Context Historically, humpback whales migrating past Aotearoa New Zealand (NZ) were linked to western South Pacific wintering grounds and Antarctic feeding grounds. As populations have recovered, research has focused on contemporary connectivity patterns …

Fishers' spatial knowledge encompasses a diverse array of social, ecological, technical, experiential, and learning knowledge derived from local environmental and sociocultural contexts. In this study, we used a transdisciplinary framework to shed light o…

Coastal marine megafauna faces increasing threats from habitat degradation, climate change, and human activities, making conservation efforts crucial for their survival. The New Caledonian dugong population was reclassified as Endangered on the IUCN Red L…

La présente note a pour objectifs de synthétiser les données acquises lors de missions ornithologiques effectuées au cours des cinq dernières décennies sur l'île Walpole, d'identifier les menaces avérées ou potentielles sur son avifaune marine et de p…

Spanning 1.3 million square kilometres, the Natural Park of the Coral Sea ranks among the largest marine protected areas on Earth. A true sanctuary of biodiversity, it harbours virtually untouched coral reefs, around 20 remote islets, and a vast expanse o…

Marine functional connectivity underpins biodiversity and ecosystem functions, ensuring resilience in marine and land-sea interface ecosystems. Research on this topic has advanced rapidly in recent decades, as reflected in the growing body of primary lite…

Since 2007, presence of mapiko and beaches of natural detrital accumulations composed mainly of giant clam valves are legal criteria to formally identify atoll lagoons where giant clam mariculture should be ecologically sustainable and authorized in the E…

The ubiquity of microplastics in the marine environment has been highlighted in recent years, yet the extent of microplastic pollution in coastal areas, especially off the coast of Japan, remains unclear. Here we provide a comprehensive data set of microp…

While the seaweed industry is developing worldwide, the untapped diversity of species in New Caledonia offers many opportunities for value-added products that can stimulate the local blue economy. However, human activities and the particular geology of th…

Madagascar harbors a rich marine biodiversity, yet detailed knowledge of its fish species remains limited. Of the 1689 species listed in 2018, only 22% had accessible cytochrome oxidase I (COI) sequences in public databases. In response to growing pressur…

The skin microbiome plays a vital role in the health of marine mammals, serving as a protective barrier and interacting with the host's immune system. There is limited knowledge about the skin microbiome of dugongs (Dugong dugon), a vulnerable species wit…

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-t…

Mass coral bleaching events are increasing in severity and frequency globally. In 2023, the wider Caribbean region experienced the longest period of marine heatwave ever recorded. Twelve sites around Martinique island, Eastern Caribbean, were surveyed in …

Each austral summer, tropical cyclones (TCs) threaten South Pacific Island nations, causing potential socioeconomic impacts. Located on the eastern edge of the South Pacific convergence zone, French Polynesia (FP) faces highly variable cyclone exposure, e…

Mesophotic coral ecosystems (MCEs), occurring between 30 and 150 m depth, are increasingly recognized for their ecological importance, yet they remain underexplored, particularly in the southwestern Indian Ocean. During benthic surveys conducted at depths…

Entanglements in fishing gear are a significant threat to cetaceans worldwide and a concern for large whales in US waters. Yet, entanglement events are infrequently observed, and their lethal and sublethal impacts are likely underestimated. Photographic a…

Aim The variety of coral taxa and environmental cues triggering broadcast spawning gave rise to contrasting theories about coral reproduction synchrony. Here, we shine a new light on this synchrony across oceans by highlighting how environmental cues modu…

Pacific islands are exposed to coastal hazards, particularly storm surges resulting from low pressure, extreme winds, and waves. While coral reefs naturally protect shorelines from incident waves, the diversity of reef geomorphologies induce various coast…

Despite their drastic impacts on coral reefs, outbreaks of the coral-feeding seastar crown-of-thorns starfish (COTS), Acanthaster, have remained a scientific enigma. Significant efforts in coral reef conservation science have been dedicated to identifying…

Les récifs coralliens sont les écosystèmes hébergeant la plus forte biodiversité de la planète et sont essentiels pour des millions de personnes à travers le monde. Cependant, sous l'action des effets du changement climatique et de diverses perturbations …
