Surface ocean pH is likely to decrease by up 0.4 units 2100 due the uptake of anthropogenic CO 2 from atmosphere. Short-term experiments have revealed that this degree seawater acidification can alter calcification rates in certain planktonic and benthic organisms, although effects recorded may be shock responses long-term ecological are unknown. Here, we show response calcareous seagrass epibionts elevated partial pressure aquaria at a volcanic vent area where habitat has been exposed high...
This synopsis focuses on the effects of climate change Mediterranean seagrasses, and associated communities, contribution main species, Posidonia oceanica, to mitigation through its role sequestering carbon dioxide. Whilst regression seagrass meadows is well documented, generally linked anthropogenic pressures, global warming could be a cause new significant regressions, notably introduction exotic rise Sea-Surface Temperature (SST), relative sea level. Seagrass communities also affected by...
To avoid photodamage, photosynthetic organisms have developed mechanisms to evade or dissipate excess energy. Lumen overacidification caused by light-induced electron transport triggers quenching of excited chlorophylls and dissipation energy into heat. In higher plants participation the PsbS protein as sensor low lumenal pH was clearly demonstrated. Although light-dependent is a property all organisms, large differences in amplitude kinetics can be observed thus raising question whether...
Abstract Spread of alien species (AS) is a serious threat to marine habitats and analysis principal descriptors their occurrence pivotal set reliable conservation strategies. In order assess the susceptibility biological invasions, dataset was gathered 3899 from 29 phyla, taken 93 sites located along Italian coast in period 2000–2012. total, 61 AS belonging 11 phyla have been recorded. Invertebrates were most represented (63%). Alien found all examined (EUNIS, level 2), although they showed...
PERSEUS project aims to identify the most relevant pressures exerted on ecosystems of Southern European Seas (SES), highlighting knowledge and data gaps that endanger achievement SES Good Environmental Status (GES) as mandated by Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, a meta-analysis existing literature pressure/impact/knowledge summarized in tables related MSFD descriptors, discriminating open waters from coastal areas. comparative assessment...
Abstract. The temporal dynamics of three seagrasses, Posidonia oceanica, Cymodocea nodosa and Zostera marina , was studied in different areas the Adriatic Sea by analysing phenological parameters biomass trends compartments seagrass systems. For this purpose, samplings were conducted 1997 once per season at each station, Otranto (southern Sea) Grado (northern Sea). Structural plant differed among seagrasses both absolute values seasonal variability. P. oceanica largest plant, showing highest...
Abstract. Submarine volcanic vents are being used as natural laboratories to assess the effects of increased ocean acidity and carbon dioxide (CO2) concentration on marine organisms communities. However, in vicinity other factors addition CO2, which is main gaseous component emissions, may directly or indirectly confound biota responses high CO2. Here we for first time expression antioxidant stress-related genes seagrass Posidonia oceanica stress levels species. Our hypothesis that unknown...
The effects of climate change are likely to be dependent on local settings. Nonetheless, the compounded global and regional stressors remain poorly understood. Here, we used CO2 vents assess how ocean acidification seagrass, Posidonia oceanica, associated epiphytic community can modified by enhanced nutrient loading. P. oceanica at ambient low pH sites was exposed three levels for 16 months. response experimental conditions assessed combining analyses gene expression, plant growth,...
Abstract The introduced green alga Caulerpa racemosa var. cylindracea grows along a broad depth range (from very shallow to 60 m depth) in the Mediterranean basin. In present work, photoacclimation capacity of this invasive variety was investigated summer, season its maximum spread. Natural populations from Gulf Naples (Italy) were analyzed for photoresponse on two scales light variability: spatial scale (at three stations gradient, 0.3 20 and temporal (on shallowest meadow, sunrise sunset)....
Studies regarding macroalgal responses to ocean acidification (OA) are mostly limited short-term experiments in controlled conditions, which hamper the possibility scale up observations long-term effects natural environment. To gain a broader perspective, we utilized volcanic CO2 vents as "natural laboratory" study OA on Sargassum vulgare at different time scales. We measured photosynthetic rates, oxidative stress levels, antioxidant contents, enzyme activities, and activities of metabolic...
Fucales (Phaeophyceae) are ecosystem engineers and forest-forming macroalgae whose populations declining dramatically. In the Mediterranean Sea, Cystoseira sensu lato (s.l.)-encompassing genera stricto, Ericaria, Gongolaria-is most diverse group, many species have been shown to be locally extinct in areas, resulting a shift toward structurally less complex habitats with consequent loss of functions services. this study, we report on extensive occurrence healthy dense marine forests formed by...
