<p><strong><em>MedSens </em>abstract</strong></p>
<p>Citizen science (CS) projects may provide community-based ecosystem monitoring, expanding our ability to collect data across space and time. However, the data from CS are often not effectively integrated into institutional monitoring programs and decision-making processes, especially in marine conservation. This limitation is partially due to difficulties in accessing the data and the lack of tools and indices for proper management at intended spatial and temporal scales. <em>MedSens</em> is a biotic index specifically developed to provide information on the environmental status of subtidal rocky coastal habitats, filling a gap between marine CS and coastal management in the Mediterranean Sea. The <em>MedSens</em> index is based on 25 selected species, incorporating their sensitivities to the pressures indicated by the European Union’s Marine Strategy Framework Directive (MSDF) and open data on their distributions and abundances, collected by trained volunteers (mainly scuba divers, but also free divers and snorkelers) using the Reef Check Mediterranean Underwater Coastal Environment Monitoring (RCMed U-CEM) protocol. The species sensitivities were assessed relative to their resistance and resilience against physical, chemical, and biological pressures, according to benchmark levels and a literature review. The <em>MedSens</em> index was calibrated on a dataset of 33,021 observations from 569 volunteers (2001 to 2019), along six countries’ coasts. A free and user-friendly QGIS plugin allows easy index calculation for areas and time frames of interest. The <em>MedSens</em> index was applied to Mediterranean marine protected areas (MPAs) and the management and monitoring zones within Italian MPAs. In the studied cases, the <em>MedSens</em> index responds well to the local pressures documented by previous investigations.</p>
<p><em>MedSens</em> converts the data collected by trained volunteers into an effective monitoring tool for the Mediterranean subtidal rocky coastal habitats. <em>MedSens</em> can help conservationists and decision-makers identify the main pressures acting in these habitats, as required by the MSFD, supporting them in the implementation of appropriate marine biodiversity conservation measures and better communicate the results of their actions. By directly involving stakeholders, this approach increases public awareness and the acceptability of management decisions, enabling more participatory conservation tactics.</p>

Manuale EcoDiver M.A.C. Guida al Monitoraggio dell'Ambiente Costiero Mediterraneo
No full textLa conservazione e gestione dell'ambiente, sia terrestre sia marino, richiede una dettagliata conoscenza della distribuzione degli organismi presenti sul territorio, del loro valore ecologico, delle possibili azioni dell'uomo che possono minacchiarli e dei cambiamenti climatici in corso. Queste conoscenze sono alla base di una corretta pianificazione deli interventi di tutela e protezione ma anche dei programmi di educazione e sensibilizzazione della popolazione, elemento chiave in qualunque politica di conservazione. Purtroppo, per quel che riguarda l'ambiente marino, i livelli di conoscenza del territorio e di sensibilizzazione delle persone sono spesso molto ridotti, Il protocollo di Monitoraggio dell'Ambiente Costiero (M.A.C.) coinvolge i subacquei nella tutela dei fondali marini sia attraverso l'opera di divulgazione e sensibilizzazione sia tramite la collaborazione con i ricercatori e i gestori delle coste. Il protocollo prevede il censimento e monitoraggio nel tempo di alcune specie marine, facilmente riconoscibili e scelte come indicatori dello stato di salute dei nostri mari, delle possibili manacce e dei cambiamenti in atto, sia a livello locale sia globale

Sinularioside, a triacetylated glycolipid from the Indonesian soft coral Sinularia sp., is an inhibitor of NO release
No full textChemical analysis of the Indonesian soft coral Sinularia sp. (order Alcyonacea, family Alcyoniidae) afforded
a known glucosylcerebroside of the sarcoehrenoside-type and sinularioside (2), a new naturally triacetylated
glycolipid containing two a-D-arabinopyranosyl residues and a myristyl alcohol unit. Their
complete stereostructures were solved by interpretation of MS and NMR data along with CD analysis
of degradation products. Sinularioside proved to moderately inhibit LPS-induced NO release, providing
interesting clues into the poorly understood structure–activity relationships for anti-inflammatory
glycolipids
Sponge cell cultivation: Optimization of the model Petrosia ficiformis (Poiret 1789)
No full textSponge cells represent a unique model for the study of the molecular evolution of animal metabolism and of the ancestral processes of biomineralization. Among various sponge culture models, the most promising ones are based on the primmorph technique, which allows the production of 3D sponge cell aggregates, easily reared in a laboratory setting.
The effects of three supplements (silicate, iron, RPMI medium) on cell proliferation, silicatein β production and HSP70 activation in Petrosia ficiformis primmorphs were investigated, as well as the relevance of endogenous spicule retention during the early phases of primmorph formation. The results show that retention of endogenous spicules together with cells during the re-aggregation phase dramatically improves primmorph formation, very likely acting as an “interactive scaffold” for cell homing and/or mediating cell adhesion signals. Furthermore, in contrast to the standard technique whose yield in terms of biomass growth is significantly lower, the addition of silicate, iron and RPMI in the early phases of primmorph formation in a restricted concentration range, as well as their maintenance during long time cultivation, gives a dramatic boost to primmorph growth. In conclusion, our examination highlights certain aspects of the P. ficiformis primmorph preparation protocol, whose implementation improves the yield and growth of sponge cells
