Background The rising temperature of the world's oceans has become a major threat to coral reefs globally as severity and frequency mass bleaching mortality events increase. In 2005, high ocean temperatures in tropical Atlantic Caribbean resulted most severe event ever recorded basin. Methodology/Principal Findings Satellite-based tools provided warnings for reef managers scientists, guiding both timing location researchers' field observations anomalously warm conditions developed spread...
The Sargassum Watch System processes satellite data and feeds results to a Web portal, giving decision makers timely information on seaweed location warnings for potential beaching events.
Biodiversity loss and climate change have severely impacted ecosystems livelihoods worldwide, compromising access to food water, increasing disaster risk, affecting human health globally. Nature-based Solutions (NbS) gained interest in addressing these global societal challenges. Although much effort has been directed NbS urban terrestrial environments, the implementation of marine coastal environments (blue NbS) lags. The lack a framework guide decision-makers practitioners through initial...
The brown alga Cystoseira baccata harvested along the Atlantic coasts of Morocco yielded seven new meroditerpenoids (1−4) and derivatives (5−7), whose chemical structures were elucidated mainly by 2D NMR mass spectrometry. Surprisingly, for all these compounds, which possess a bicyclo[4.3.0]nonane ring system, trans fusion bicyclic system was deduced stereochemical studies even though such compounds isolated from species are known to have typical cis orientation bridgehead methyls....
Coral reefs of Mayotte (342 km2), seagrass beds (7.6 km2) and mangroves (8.5 provide important ecosystem services which the most are coastal protection, fish biomass production, carbon sequestration water purification. The quantity quality these have been decreasing steadily for several years should continue to do so if no action is taken contain anthropogenic pressures. coral cover fringing barrier reef has thus declined, respectively, by 60% in 15 15% 8 years. pioneer front Sonneratia...
Submerged marine surfaces are rapidly colonized by fouling organisms. Current research is aimed at finding new, non-toxic, or least environmentally benign, solutions to this problem. Barnacles a major target organism for such control as they constitute key component of the hard community. A range standard settlement assays available screening test compounds against barnacle cypris larvae, but generally provide little information on mechanism(s) action. Towards end, quick and reliable...
Although sponges are important components of benthic ecosystems the Caribbean Sea, their diversity remained poorly investigated in Lesser Antilles. By organizing a training course Martinique, we wanted both to promote taxonomy and provide first inventory sponge on this island. The was like naturalist expedition, with field laboratory classroom nearby. Early-career scientists environmental managers were trained taxonomy. We gathered unpublished data conducted an at 13 coastal sites. explored...
Coastal marine ecosystems ensure fundamental hydro-ecological functions and support high levels of biodiversity, besides being an important resource for local populations. These biocenosis have been increasingly threatened by human pressures (e.g. pollution, overfishing) along with climate change, which may a dramatic impact on them. The National Park Banc d'Arguin (PNBA) in Mauritania, one the biggest parks Western Africa, is RAMSAR zone (classified UNESCO since 1989) that plays major role...
Coral reefs have undergone profound ecological changes over recent decades. Areas formerly covered by scleractinian coral species are now often overgrown macroalgae. In Martinique (West Indies), this phenomenon has lead to the colonisation of numerous algae, amongst which Sargassum is one most prominent. This study focuses on potential defence molecules produced polyceratium. The hexane dipping method was employed extract surface fresh material, and their bioactivities were assessed against...
Our societies are actively seeking solutions to address the crises of biodiversity loss and climate change. In this context, European Horizon 2020 project MaCoBioS (2020-2024) supports effective integrated management conservation strategies for marine coastal ecosystems face goals were: better understand inter-relations between change, biodiversity, functions services in ecosystems; assess vulnerability socio-ecological systems under change scenarios; evaluate effectiveness Nature-based...
Interconnected societal challenges such as climate change, biodiversity loss and food security demand immediate coordinated action across local to global scales, guided by coherent policies management mechanisms. Reflecting on the critical need address challenges, Nature-based Solutions in marine coastal environments, known blue NBS, have emerged an important part of response strategy. Blue NBS integrate actions protect restore ecosystems while managing human impacts, embedding nature people...
Cystophloroketals A–E (1–5), five new phloroglucinol–meroditerpenoid hybrids, have been isolated together with their putative biosynthetic precursor, the monocyclic meroditerpenoid 6, from Mediterranean brown alga Cystoseira tamariscifolia. They represent first examples of meroditerpenoids linked to a phloroglucinol through 2,7-dioxabicyclo[3.2.1]octane moiety. The chemical structures, including absolute configurations, were elucidated on basis extensive spectroscopic analysis (HR-ESIMS, 1D...
Abstract Marine coastal ecosystems are crucial to human populations in reducing disaster risk. Least Developed Countries particularly vulnerable the effects of climate change, such as sea‐level rise and storm surges. The Mauritanian coast, West Africa, ranks among most worldwide rise, communities National Park Banc d’Arguin (PNBA) at Here, we assessed service protection PNBA by (1) mapping marine with Sentinel‐2 imagery determining their spatial wave height attenuation rates; (2) assessing...
