The Mediterranean Sea is the second largest biodiversity hotspot on earth, with over 700 identified fish species facing numerous threats. Of more than 6000 taxa assessed for IUCN Red List, a minimum of 20% are threatened extinction.

Quantifying co‐extinctions and ecosystem service vulnerability in coastal ecosystems experiencing climate warming

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(7)

Published: July 1, 2024

Abstract Climate change is negatively impacting ecosystems and their contributions to human well‐being, known as ecosystem services. Previous research has mainly focused on the direct effects of climate species services, leaving a gap in understanding indirect impacts resulting from changes interactions within complex ecosystems. This knowledge significant because loss food web can lead additional losses or “co‐extinctions,” particularly when most impacted by are also that play critical roles persistence provide Here, we present framework investigate relationships among vulnerability change, web, overall these systems services face climate‐induced losses. To do this, assess robustness webs associated climate‐driven extinctions eight empirical rocky intertidal webs. Across webs, find highly connected not vulnerable change. However, directly more than which results service provision collapsing before Overall, robust they show combining with offer predictions about co‐extinctions for future persistence. conclusions limited data availability quality, underscoring need comprehensive collection linking interaction networks vulnerabilities

Chronicles of Kyphosus in the Mediterranean Sea: new records and complete mitogenomes support the scenario of one expanding fish species

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: July 24, 2024

The Mediterranean Sea is a biodiversity hotspot, being home to vast array of marine species. Furthermore, seawater warming facilitating the arrival and spread new thermophilic species, posing severe threat biodiversity. Among species currently extending their range increasing in abundance waters, sea chubs (genus Kyphosus ) are one most enigmatic. One challenge arises from high phenotypic similarity between two congeneric documented basin: vaigiensis sectatrix . Their resemblance has often led identification challenges, resulting incorrect or omitted species-level classifications. Therefore, despite growing presence these fish Mediterranean, it remains unclear whether only both experiencing demographic increase extension. To date, there have been 26 reports individuals Sea, 24 separate papers. Here, we reviewed history genus basin provided 13 records multiple localities along coasts. In addition, sequenced entire mitogenomes specimens, assessed phylogenetic relationships with published mitochondrial DNAs around world, conducted detailed morphological meristic analyses on them, allowing us provide accurate identifications. Our results indicate that K. expanding its while still very rare sporadically reported. Notably, our mitogenome data likely came Atlantic no evidence support an entrance through Red any other anthropogenic vector.

Climate change has presented a serious problem in recent times, which is why new approach being sought terms of aquacultural food quality. In this study, the influence temperature increase (by 2 °C) and pH decrease 0.2) was investigated on queen scallop, Aequipecten opercularis (Linnaeus, 1758). Furthermore, effect food-enriched diet with probiotic culture Lactiplantibacillus plantarum I assessed climate-changed conditions. Scallops’ morphometric parameters were measured before experimental setup after one month kept controlled Morphometric included elongation index, compactness convexity density condition meat yield, gonadosomatic adductor muscle hepatosomatic index.

Abstract Marine heat waves (MHWs) have increased in frequency and intensity worldwide, causing mass mortality of benthic organisms loss biodiversity shallow waters. The Mediterranean Sea is no exception, with populations habitat-forming octocorals facing the threat local extinction. mesophotic zone, which less affected by MHWs, may be ecological importance conservation strategies for these species. However, our understanding response octocoral holobionts to changes seawater temperature remains limited. To address this knowledge gap, we conducted a study on an iconic octocoral, red coral Corallium rubrum sampled at 60 m depth 15 °C. We exposed colonies temperatures they occasionally experience (18 °C) that could occur end century if global warming continues (21 °C). also tested their extremely cold warm (12 °C 24 Our results show high tolerance C. two-month long exposure ranging from 12 21 as colony showed signs tissue loss, reduced feeding ability, stress-induced gene expression, or disruption host-bacterial symbioses.

Climate change risks on key open marine and coastal Mediterranean ecosystems

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 24, 2024

Mediterranean open marine and coastal ecosystems face multiple risks, due to climate change, that impact their unique biodiversity. To assess these risks evaluate confidence levels, we adopt the scenario-based approach of Intergovernmental Panel on Climate Change (IPCC), relying a review literature projecting changes in Sea ecosystems. The main drivers environmental change are sea level rise, ocean warming acidification. Similar global conditions, all high under scenarios, with being more strongly impacted than For ecosystems, risk levels expected become very already once exceeds 0.8°C respect 1976–2005 period. A few (e.g., coralligenous rocky coasts) have greater adaptive capacity others, probably because long evolutionary history this presence variety climatic hydrological conditions. Overall, higher observed projected rates Mediterranean, compared trends, for variables such as seawater temperature pH, (particularly coastal) be ocean.
