Full-text available
The terrestrial and marine Port-Cros National (PCNP) was established in 1963; it was then made up only of the Archipelago of Port-Cros. Since 2012, it has been extended to include a vast land and sea area, including not only islands but also part of the mainland, the new PCNP (N-PCNP); the marine core area and the adjacent marine area cover approxi...

Potential for, and limits to, adaptation to environmental changes are critical for resilience and risk mitigation. The Mediterranean basin is a mosaic of biodiversity-rich ecosystems long affected by human influence, whose resilience is now questioned by climate change. After reviewing the different components of biological adaptation, we present t...

The Port-Cros National Park (PCNP), established in 1963, was one of the earliest terrestrial and marine parks in the Mediterranean Sea. From 2012, it engaged in a major redefinition and extension of its territory (N-PCNP—New Port-Cros National Park). This case is particularly interesting insofar as the protected area has been competently and effici...
Article
The Red Sea and Indian Ocean seagrass Halophila stipulacea entered the Mediterranean in the late 19th century via the Suez Canal. Here, we report on the discovery of a population of H. stipulacea covering 16.5 ha off the harbour of Cannes, French Riviera, France. This represents the northernmost locality of the species and a jump of 350 km to the n...

The temperate Northwest Pacific brown alga Rugulopteryx okamurae (Dictyotales, Phaeophyceae) was first discovered in 2002 in the Mediterranean Sea in the Thau coastal lagoon (Occitania, France) and then again in 2015 along the southern side of the Strait of Gibraltar, where it was assigned with invasive status. We report here on the first occurrenc...
Article
Within the frame of a natural environment impacted by anthropogenic activities, assessing and quantifying their related pressures are essential to its management and are linked to its status. However, there are no, or very few, geographical areas where thorough knowledge of human uses and sources of impact is available as a basis to quantify these...
Article
Full-text available
Dispersal is a central process that affects population growth, gene flow, and ultimately species persistence. Here we investigate the extent to which gene flow occurs between fragmented populations of the deep-water brown algae Ericaria zosteroides (Turner) Greville (Sargassaceae, Fucales). These investigations were performed at different spatial s...
Article
Full-text available
Some species of seagrasses (e.g., Zostera marina and Posidonia oceanica) have declined in the Mediterranean, at least locally. Others are progressing, helped by sea warming, such as Cymodocea nodosa and the non-native Halophila stipulacea. The decline of one seagrass can favor another seagrass. All in all, the decline of seagrasses could be less ex...
Article
Coastal marine vegetation has been recently highlighted for its highly efficient carbon storage capacity. Among the sixty-four species of seagrass, Posidonia oceanica, a Mediterranean endemic species, appears to be the most effective in carbon fixation and storage. Based on new data from the study of one of the largest P. oceanica meadows in the Me...

Article
Full-text available
The direct and indirect impact of fish farms, shellfish aquaculture, and extensive forms of aquaculture such as seeding of juvenile sea urchins, on macrophytes (seaweeds and seagrasses), is reviewed in Mediterranean benthic ecosystems. Fish farms constitute a source of organic matter and nutrients (food and fecal pellets) that causes the extirpatio...
Article
Full-text available
The management of saltmarshes, the complex ecosystem constituted by coastal wetlands and lagoons (SME – Saltmarsh Ecosystem), is often centered on the so-called ‘heritage species’ (rare, threatened and charismatic species). This ‘species-centered’ or ‘taxon-centered’ approach, a legacy from the 20th century, is fully understandable in areas where d...
Article
The saltmarshes of Hyères (Provence; France) are Mediterranean lagoons and wetlands deeply altered since Antiquity; they are an example of a socio-ecosystem characterized by industrial activities since 1848 for salt production and artisanal fishing. After the end of the industrial exploitation in 1995, saltmarshes of Hyères became property of the C...
Chapter
Macroalgae are a key component of benthic coastal ecosystems. They are sensitive to natural and anthropogenic disturbances. In the Mediterranean Sea, macroalgae can be used by environmental managers (i) to delineate biogeographic provinces (on the basis of their range), (ii) as indicators of global warming (based on changes in their distribution ar...

Jannick Olivier was born in 1948 in Bizerte (Tunisia). She was the daughter of Janine Parascandola and Guy Canton, who enlisted in the French Air Force. He went missing in action in 1954 in Indochina: at 6 years old, Jannick was fatherless. She studied biology and ecology, then regional management and planning. This dual academic background was to...
Article
Full-text available
The Mediterranean Posidonia oceanica seagrass meadows provide a variety of ecosystem services; one of them is the protection of beaches against erosion, due to the accumulation on beaches of drift dead leaves, which forms what is known as 'banquettes'. In most Mediterranean areas, the P. oceanica banquette is considered as waste that has a negative...
Article
Seagrass meadows have long been recognized for their high ecological and economic value (ecosystem services). More recently, a potential role in climate regulation, due to their ability to fix and sequester carbon, has been the focus of intensive study. In the Mediterranean Sea, the matte, a specific structure built by the seagrass Posidonia oceani...

Article
Posidonia oceanica is an iconic and highly productive Mediterranean seagrass. As most studies have focused on the fate of its production, temporal and plant part-specific variations of isotopic composition and biochemical content were overlooked. Combined seasonal and plant-part stable isotope composition and biochemical concentrations were measure...

Lost and abandoned fishing gear affects all marine habitats, both coastal and offshore habitats such as bathyal habitats, including canyons. Not only professional fishing nets, longlines and fishing traps are concerned, but also recreational fishing tackle (fishing lines, lead weights, hooks, etc.). This lost gear causes various forms of negative i...

The Posidonia oceanica seagrass meadows are very sensitive to disturbance of human or natural origin. Here we consider the losses of the seagrass localized near the lower limit of the meadow in the Bay of Hyères (France). Samples of dead matte were taken near and beyond the current lower limit of the meadow, between 26 and 37 m depth. Radiocarbon 1...

Coastal detrital sandy bottoms are an ecosystem (CDE) widespread over the continental shelf from 30 down to 100 m depth in the Mediterranean Sea. Despite the extensive surface area it covers on the continental shelf, this key ecosystem has not been considered as a habitat of European interest by the Habitat Directive of the European Union (Natura 2...

The dynamics of natural monuments such as the Posidonia oceanica reefs is poorly known. The Posidonia barrier-reef Port-Cros has served as a laboratory for Molinier and Picard back in the 1950s and enabled them to describe the process of building of P. oceanica fringing and barrierreefs, while the Saint-Florent platform-reef, mapped for the first t...

The modern biodiversity crisis, the seventh extinction, is different from the six former crises in that one species, Man, is alone responsible, rather than volcanic and astronomic events. In addition to species that have become extinct due to human activity, an increasing number of species are threatened (critically endangered, endangered, vulnerab...
