Article
Full-text available
Ocean acidification (OA) refers to the worldwide decrease of average pH of surface seawaters due to increasing emissions of anthropogenic carbon dioxide (CO2) since the industrial revolution. OA severely affects marine life, from effects on single species to whole ecosystems, due to the physiological stress of low-pH/high-pCO2 environments. However...

Article
Full-text available
Climate change is causing an increase in the frequency and intensity of marine heatwaves (MHWs) and mass mortality events (MMEs) of marine organisms are one of their main ecological impacts. Here, we show that during the 2015–2019 period, the Mediterranean Sea has experienced exceptional thermal conditions resulting in the onset of five consecutive...
Article
This study aimed to assess the combined effects of ocean acidification (OA) and pollution to the polychaete Syllis prolifera inhabiting the CO2 vent system of the Castello Aragonese (Ischia Island, Italy). We investigated the basal activities of antioxidant enzymes in organisms from the acidified site and from an ambient-pH control site in two diff...
Article
Savalia savaglia is an ecosystem engineer listed as Near-Threatened by the IUCN, even though effective management and proper monitoring efforts to assess its distribution is still lacking. The record of large, long-established colonies can indicate the occurrence of areas with limited human local pressure. These areas may be considered as proxies f...
Article
Anthropogenic stressors are predicted to alter biodiversity and ecosystem functioning worldwide. However, scaling up from species to ecosystem responses poses a challenge, as species and functional groups can exhibit different capacities to adapt, acclimate, and compensate under changing environments. We used a naturally acidified seagrass ecosyste...
Technical Report
Full-text available
It is reported the record of a conspicuous population (several hundreds) of the non-native heterobranch mollusc Lamprohaminoea ovalis (previous Haminoea cyanomarginata) along the coast of the Argentario peninsula (Italy), one of the northernmost location of occurrence for this Red Sea alien species in the Mediterranean Sea.
Article
As the ocean warms, the thermal tolerance of marine invertebrates is key to determining their distributional change, where acclimation to low pH may impact the thermal range of optimal development. We compared thermal tolerance of progeny from a low pH-acclimated sea urchin (Arbacia lixula) population from the CO 2 vents of Ischia (Italy) and a nea...

Considering the pivotal role played by erosive organisms in the marine habitat and the scanty knowledge of this phenomenon in the Mediterranean Sea, the present study aimed to identify the pioneer excavating organisms occurring in the first stages of bioerosion, providing the first estimation of their rate of erosion along the North Adriatic Sea. B...
Article
Full-text available
Ocean acidification (OA), one of the main climate-change-related stressors linked to increasing CO2 concentration in the atmosphere, is considered an important threat to marine biodiversity and habitats. Studies on CO2-vents systems, naturally acidified environments that mimic future ocean scenarios, help to explore the sensitivity of species and t...
Conference Paper
Full-text available
A major goal of global environmental change research is to determine the effects of the main drivers on species and communities, and whether organism’s biological responses persist and are maintained at levels that are similar to, or different from today. To this purpose, several studies were conducted on marine hydrothermal vents, unique extreme e...

Abstract The Nereid Platynereis dumerilii (Audouin and Milne Edwards (Annales des Sciences Naturelles 1:195–269, 1833) is a marine annelid that belongs to the Nereididae, a family of errant polychaete worms. The Nereid shows a pelagobenthic life cycle: as a general characteristic for the superphylum of Lophotrochozoa/Spiralia, it has spirally cleav...
Article
Full-text available
Ocean acidification has been broadly recognised to have effects on the structure and functioning of marine benthic communities. The selection of tolerant or vulnerable species can also occur during settlement phases, especially for calcifying organisms which are more vulnerable to low pH–high pCO2 conditions. Here, we use three natural CO2 vents (C...

Effects of ocean acidification (OA) on the plant phenology and colonization/settlement pattern of the hydrozoan epibiont community of the leaves of the seagrass Posidonia oceanica have been studied at volcanic CO2 vents off Ischia (Italy). The study was conducted in shallow Posidonia stands (2.5–3.5 m depth), in three stations on the north and thre...
Article
We report the description of nine new taxa of sabellid polychaetes belonging to the genus Amphiglena, of which diversity in the Mediterranean Sea has been widely underestimated. Examined material derived from both new collections along the Italian coast, including four CO 2 vents/hydrothermal systems, and from a re-examination of older material pre...
Conference Paper
Acidificazione e riscaldamento globale degli oceani rappresentano i drivers dei maggiori cambiamenti negli ecosistemi marini (Sabine et al. 2004), a danno soprattutto degli organismi calcificatori (Fabry et al. 2008). Le Isole Eolie rappresentano un laboratorio naturale idoneo per elaborare modelli e scenari per lo studio della Carbon Capture and S...
Article
Ocean acidification (OA) may induce major shifts in the structure and function of coastal marine ecosystems. Studies in volcanic CO2 vents, where seawater is naturally acidified, have reported an overall simplification of fish assemblages structure, while some primary producers are likely to increase their biomass under elevated concentration of CO...

The spionid polychaete Pseudopolydora paucibranchiata (Okuda, 1937) was originally described from Japan and has since been reported as a non-indigenous species in soft bottom communities in the Northeast Pacific, the Mediterranean Sea, around Europe, Australia, Brazil, and Florida. The diagnostic features of the adults are palps with ramified yello...
Article
High pCO2 habitats and their populations provide an unparalleled opportunity to assess how species may survive under future ocean acidification conditions, and help to reveal the traits that confer tolerance. Here we utilize a unique CO2 vent system to study the effects of exposure to elevated pCO2 on trait‐shifts observed throughout natural popula...

The alien seagrass Halophila stipulacea has invaded the Mediterranean Sea from the Red Sea more than 120 y ago, and first recorded in the western Mediterranean Sea in 1995 (Vulcano island, Sicily). The species has further expanded ∼110 nautical miles northward, reaching the harbour of Palinuro (Tyrrhenian Sea, Italy) in 2006, which currently repres...
Article
Ocean acidification (OA) influences the production of volatile organic compounds (VOCs) by seagrass leaves and their associated epiphytes. We hypothesize that the perception of "odour" produced by seagrass leaf epiphytes will change with seawater acidification, affecting the behaviour of seagrass-associated invertebrates. To test this hypothesis, w...
