Diver assessments can reveal much about coral reef condition, but fieldwork is expensive and challenging. To address this limitation to effective reef assessment, we identified predictive relationships between diver measurements of reef condition collecte…

Seabirds have been particularly affected by invasive non-native species, which has led to the implementation of numerous eradication campaigns for the conservation of these keystone and highly vulnerable species. Although the benefits of eradication of in…

Considered as a transitional object, the comforting power of the teddy bear has often been asserted in many past studies without knowing its underlying determinants. Through a participatory study conducted during the European Researchers' Night, this stud…

Marine protected areas (MPAs) are among the most effective management responses to human environmental impacts. However, their capacity to sustain biodiversity and associated ecosystem services under climate change is uncertain. Understanding how climate …

Since the 1980s, the Common Fisheries Policy (CFP) has shaped European fisheries. It has often been criticised for being too prescriptive and, above all, for failing to protect either fishermen or ecosystems. The last reform dates back to the early 2010 s…

From 2014 to 2021 during the cyclone seasons, extensive monitoring of the hydrodynamics within a variety of lagoons of New Caledonia was conducted as a part of the PRESENCE project (PRESsures on coral Ecosystems of New CalEdonia). The PRESENCE project is …

The silvertip shark, Carcharhinus albimarginatus, is a coral reef-associated shark with a wide distribution across the Indo-Pacific. Yet, unlike common reef shark species, limited knowledge exists on its movement patterns. Here, we tracked 28 individuals …

The blue shark Prionace glauca is a top predator with one of the widest geographical distributions of any shark species. It is classified as Critically Endangered in the Mediterranean Sea, and Near Threatened globally. Previous genetic studies did not rej…

The present study contributes to update the checklist of Lanternfishesspecies of the genus Diaphus known to occur in the tropical southwestern Pacific. The findings are based on material collected from six recent oceanographic cruises of RV Alis in the C…

Global change is altering interactions between ecological disturbances. We review interactions between tropical cyclones and fires that affect woody biomes in many islands and coastal areas. Cyclone-induced damage to trees can increase fuel loads on the g…

The present study characterized complete mitochondrial genome of Blue-spotted maskray, Neotrygon indica and studied the evolutionary relationship of the species within the Dasyatidae family. The total length of the mitogenome was 17,974 bp including 37 ge…

Updated information on the spatial distribution of mangrove forests is of high importance for management plans. Yet, access to mangrove distribution maps is limited, even-though remote sensing data is currently freely available and deep learning algorithm…

Traditional fishery management schemes have gained increasing recognition worldwide. It can be explained by a better compliance to ancient cultural practices, still rooted in present-day coastal communities despite globalization and modern livelihoods. Th…

Pelagic fauna is expected to be impacted under climate change according to ecosystem simulations. However, the direction and magnitude of the impact is still uncertain and still not corroborated by observation-based statistical studies. Here we compile a …

Study region: The eastern coast of New Caledonia (SW Pacific).Study focus: The HydroThiem hydrological observatory is devoted to the study of the impact of invasive ungulate species and bushfires on water resources, erosion and water quality in a catchmen…

Tropical reefs and the fish relying on them are under increasing pressure. Shallow-reef fish provide important ecological information in addition to sustaining fisheries, tourism and more. Although empirical metrics of fish biomass are widely used in fish…

Pelagic fauna is expected to be impacted under climate change according to ecosystem simulations. However, the direction and magnitude of the impact is still uncertain and still not corroborated by observation-based statistical studies. Here we compile a …

Knowledge of the status of the black-lipped pearl oyster Pinctada margaritifera populations is critical for the sustainability of the French Polynesia black pearl farming industry. Indeed, this activity relies on collection of spat settling out of the wat…

The morphology of an individual can improve its ability to escape predators and ultimately its chances of survival. Sicydiine fishes reproduce in rivers, and their larvae develop in the sea. Once juveniles arrive in rivers, they face numerous predatory fi…

Rainfall projections from the Coupled Model Intercomparison Project (CMIP) models are strongly tied to projected sea surface temperature (SST) spatial patterns through the "warmer-gets-wetter" mechanism. While these models consistently project an enhanced…

Coral reefs around the world are under threat from anomalous heat waves that are causing the widespread decline of hard corals. Different coral taxa are known to have different sensitivities to heat, although variation in susceptibilities have also been o…

The Western Indian Ocean (WIO) is comprised of productive and highly diverse marine ecosystems that are rich sources of food security, livelihoods, and natural wonder. The ecological services that species provide are vital to the productivity of these eco…

At a time when protecting the environment is urgent, dealing with inherent uncertainties in the responses of biodiversity to disturbances is essential. This study promotes a promising tool to assess the vulnerability of species assemblages to guide protec…

For more than a decade, high-throughput sequencing has transformed the study of marine planktonic communities and has highlighted the extent of protist diversity in these ecosystems. Nevertheless, little is known relative to their genomic diversity at the…

Toxic seaweed dermatitis is caused by toxins of the marine cyanobacterium Lyngbya majuscula after sea bathing in some tropical area. This rarely described irritant dermatitis results in papular and bullous lesions, mainly in the genital area but severe oc…

Correctly delimiting species and populations is a prerequisite for studies of connectivity, adaptation and conservation. Genomic data are particularly useful to test species differentiation for organisms with few informative morphological characters or lo…

We re-evaluated the diversity of Lobophora using an integrative taxonomic approach based on a broad sampling across French Polynesian archipelagos. Our results show that French Polynesia supports at least 37 Lobophora species of which similar to 57% (21) …
