Abstract Unraveling the functional future of marine ecosystems amid global change poses a pressing challenge. This is particularly critical in Mediterranean Sea, which highly impacted by and local drivers. Utilizing extensive mass mortality events (MMEs) datasets spanning from 1986 to 2020 across we investigated trait vulnerability benthic species that suffered MMEs induced nine distinct By analyzing changes ten ecological traits 389 species—constituting an compendium date—we identified 228 entities (FEs), defined as groups sharing same values. Our findings indicate these 55 FEs were MMEs, accentuating heightened within specific categories. Notably, more than half records showed severe impacts on calcifying larger with slower growth mostly account for tree-like massive forms. Altogether, highlight 29 extreme mortality, leading maximum increase 19.1% volume over 35 years. We also reveal 10.8% may have been temporarily lost last five years, emphasizing risk rapid transformation Sea.

Living under natural conditions of ocean acidification entails energy expenditure and oxidative stress in a mussel species

Marine Pollution Bulletin, Год журнала: 2024, Номер 203, С. 116470 - 116470

We investigated the health conditions of Mediterranean mussel Mytilus galloprovincialis recruited in CO2 vents system Castello Aragonese at Ischia Island (Mediterranean Sea). Individuals M. were sampled three sites along pH gradient (8.10, 7.7 and up to <7.4). Untargeted metabolomics biochemical endpoints related energetic metabolism, oxidative stress/damage, neurotoxicity immune defense analyzed. Corrosion valves occurred low pH. A separation metabolome was observed gradient. Metabolites belonging amino acids, nucleosides, lipids organic osmolytes significantly reduced organisms from most acidified sites. The content reactive oxygen species activity glutathione peroxidase compared ambient pH, no damage induced. Overall results suggested presence an energy cost underpinning long-term survival for this species.

Ocean Acidification Influences Site Fidelity and Seagrass Habitat Use by an Herbivorous Fish

Опубликована: Янв. 1, 2025

Ocean acidification (OA), characterised by a change in seawater chemistry and concomitant decline pH due to the uptake of increased anthropogenic CO2, will profoundly shape marine ecosystems. CO2 can act negatively (as stressor for organisms with calcareous exoskeleton) or positively direct resource primary producers like macrophytes). Consequently, herbivores may indirectly take advantage OA counteracting negative effects living under high pCO2/low conditions. Here, we investigated how influence site fidelity, habitat use, trophic behaviour patterns Sarpa salpa, main herbivorous fish associated Posidonia oceanica meadows north-western Mediterranean Sea. We assessed if influences use S. salpa comparing natural tags such as otolith muscle at vents reference sites. did not find differences elemental composition among exposed different conditions (CO2 vent vs ambient sites). However, isotopic signal showed life stages (young sub-adults), following same trend both otoliths seawater-dissolved inorganic carbon signal. Finally, found higher nutritional value P. its epiphytes consequent increase their consumption compared This separation indicates that spent more time exploiting resources vents. Our findings shed new light on food web future scenarios.

Beyond biodiversity: the role of Paramuricea clavata forests in supporting ecosystem functioning

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 18, 2025

Marine animal forests, composed of sessile suspension feeders such as gorgonians are known to host rich communities that support important ecosystem functions and services. These habitats undergoing dramatic loss due multiple pressures, with potential cascading effects on dynamics remain poorly understood. To address this critical knowledge gap, we used fine-scale data assess the role Paramuricea clavata forests in supporting biodiversity functioning at locations, a regional scale. Through functional trait analysis, compared taxonomic diversity benthic assemblages inside outside P. investigated traits consequence forest loss. Analyses revealed significant enhancements both within observed increased species richness. Trait-based investigations higher abundance colonial heterotrophic while outside, were dominated by low-longevity autotrophs, suggesting modifies environmental variables creating unique ecological conditions favor specific traits. β-diversity measurements demonstrated compositional turnover indicating provides more available niches, replacement functions. Our findings offer insights into how marine can structure communities, broader implications for understanding changing ecosystems.

High heterotrophic capacity favors Mediterranean coral success and resilience in the face of ocean acidification

Coral Reefs, Год журнала: 2025, Номер unknown

Abstract Coral ecosystems support a diverse array of marine life and healthy ecological functioning, yet they are vulnerable to decreases in ocean pH caused by anthropogenic carbon dioxide emissions. In temperate rocky reefs the Mediterranean, corals Cladocora caespitosa Astroides calycularis live at sites with ambient seawater adjacent submarine volcanic CO 2 vent low where it is more energetically demanding grow. We collected from distinct (average T 8.05) lower 7.74–7.90) quantified their physiological health heterotrophic capacity (i.e., feeding capacity). Both species had higher than site counterparts, enabling them maintain energy reserves. Our results indicate that high underlies success these two sites. Therefore, conservation coral could be strategically important maintaining reef ecosystem function resilience Mediterranean.
