En 1986, la mission de recherche des Terres australes et antarctiques françaises (TAAF) cherche un moyen de développer la connaissance de la faune et de la flore des fonds marins en terre Adélie, délaissée depuis près de trente ans. Une campagne de plongée est rganisée pour la première fois.
Article
The Kerguelen Islands are part of the French Southern Territories, located at the limit of the Indian and Southern oceans. They are highly impacted by climate change, and coastal marine areas are particularly at risk. Assessing the responses of species and populations to environmental change is challenging in such areas for which ecological modelli...

Conceived as a baseline for the management and conservation of the marine protected area of the French Southern Territories (réserve naturelle nationale des Terres australes françaises), the checklist of marine macroalgae of the Kerguelen Islands was updated based on an extensive review of the literature and scientific databases, from the first rep...

La décision d'extension des aires protégées portant leur part à 30% du territoire d'ici 2022 a provoqué une démarche d'éco-régionalisation (RNN-TAF) incluant l'état des lieux des connaissances sur le benthos. La 1ère expédition scientifique à St-Paul est celle de la Novara (1857), plus de 300 ans après qu'Amsterdam a été aperçue par Magellan. Très...
Article
Daily weather regimes are defined around the Kerguelen Islands (Southern Ocean) based on daily 500 hPa geopotential height anomalies derived from the ERA5 ensemble reanalysis over the period 1979-2018. Ten regimes are retained as significant. Their occurrences are highly consistent across reanalysis ensemble members. Regimes show weak seasonality a...

Members of the trochoidean genus Margarella (Calliostomatidae) are broadly distributed across Antarctic and sub-Antarctic ecosystems. Here we used novel mitochondrial and nuclear gene sequences to clarify species boundaries and phylogenetic relationships among seven nominal species distributed on either side of the Antarctic Polar Front (APF).

• 1. The coralligenous habitat was studied at the large Mediterranean scale, by applying a standardized, non‐destructive photo‐sampling protocol, developed in the framework of the CIGESMED project. • 2. The results provided evidence to support the following statements: (a) the assemblage pattern is not homogeneously distributed across the four Medi...
Conference Paper

One of the current challenges in today's ecology research is to understand and quantify the effects of climate changes on biodiversity. In order to detect possible trends in biodiversity patterns, it is necessary to conduct long-term observations in various and representative environments. This is always challenging, even more difficult in marine h...

In the current context of climate change, sea-surface temperature variation, sea level rise and latitudinal shifts of currents and hydrological fronts are expected to affect marine biodiversity of the sub-Antarctic Islands, particularly in coastal waters. Characterising the impacts of climate change on marine communities requires recording environm...
Conference Paper
Full-text available
In the Kerguelen Islands, the multiple effects of climate change are expected to impact coastal marine habitats. Species distribution models (SDM) can represent a convenient tool to predict the biogeographic response of species to climate change but biotic interactions are not considered in these models. Nevertheless, new species interactions can e...

Les suivis à long terme sont un des outils indispensables à la définition de l’état de santé des écosystèmes et à leur gestion. Si le benthos côtier animal est relativement bien connu, il n’en est pas de même pour la flore marine des îles Kerguelen. Les macroalgues étant un élément très important du benthos, mais aussi mal connu, le programme Prote...

Les habitats marins côtiers des îles subantarctiques françaises concentrent une biodiversité originale qui est aujourd'hui confrontée à des changements environnementaux dont les effets sont encore mal cernés. Comprendre l'impact de ces changements et la réponse des écosystèmes implique de mieux les connaître mais aussi d'établir un suivi régulier e...

Hard substrata Monitoring Settlement Scientific diving A B S T R A C T We investigated the validity of Autonomous Reef Monitoring Structures (ARMS) as monitoring tools for hard bottoms across a wide geographic and environmental range.

Coralligenous habitats are bioconstructed, emblematic habitats of the Mediterranean Sea, which display a remarkably complex tridimensional structure and are considered as one of the most important biodiversity hotspots of the Mediterranean Sea. In order to assess the specific diversity of these habitats we sampled small surfaces (10 cm 2) of these...

Article
The understanding of ecosystem services is essential to support sustainable use and preservation of ecosystems. Coralligenous habitats, main contributors of the Mediterranean marine biodiversity, are yet understudied in term of services provided. This study presents an original small-scale approach to investigate the services provided by coralligen...

Coralligenous habitats are emblematic biogenic constructions of the Mediterranean Sea built-up in dim light conditions by organisms from various phylogenetic groups such as calcareous coralline algae (CCA), bryozoans, polychaetes, cnidarians, mollusks, sponges, crustaceans and foraminiferans (Ballesteros 2006). The resulting framework harbors micro...

The Mediterranean basin is a region of high biodiversity, marine and terrestrial, with important endemism. This diversity has faced long-lasting, strong and increasing human demographic pressure. The relatively more recent effects of climate change are well visible in the Mediterranean basin, with for example, heat wave and summer-drought related m...

In a world of declining biodiversity, monitoring is becoming crucial. Molecular methods, such as metabarcoding, have the potential to rapidly expand our knowledge of biodiversity, supporting assessment, management, and conservation. In the marine environment, where hard substrata are more difficult to access than soft bottoms for quantitative ecolo...

One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some marine benthic species to move, adapt or go extinct. The marine benthic species inhabiting the Antarctic upper continental shelf...

Marine life of the Southern Ocean has been facing environmental changes and the direct impact of human activities during the past decades. Benthic communities have particularly been affected by such changes although we only slowly understand the effect of environmental changes on species physiology, biogeography, and distribu- tion.

Species flocks (SFs) fascinate evolutionary biologists who wonder whether such striking diversification can be driven by normal evolutionary processes. Multiple definitions of SFs have hindered the study of their origins. Previous studies identified a monophyletic taxon as a SF if it displays high speciosity in an area in which it is endemic (crite...

We assess biogeographical patterns, population structure and the range of species in the pulmonate genus Siphonaria across the sub-Antarctic. We hypothesized that locally endemic cryptic species will be found across the distribution of these direct-developing limpets in the sub-Antarctic. The sub-Antarctic coasts of the Southern Ocean including Sou...

The one thing in common “archaeological”, “biodiversity” or “social systems” studies share is that data production is both expensive and few automated. Long time series and / or large spatial surveys are difficult to conduct, since it is necessary to use several observers. The robustness and reproducibility of the observation are also harder to get...

The differential response of marine populations to climate change remains poorly understood.

Increasing atmospheric carbon dioxide concentration alters the chemistry of the oceans towards more acidic conditions. Polar oceans are particularly affected due to their low temperature, low carbonate content and mixing patterns, for instance upwellings. Echinodermata were hypothesized to be at risk due to their high-magnesium calcite skeleton. H...
