Could European marine conservation policy benefit from systematic conservation planning?

1. The Natura 2000 network of protected areas aims to assure the long-term survival of Europe’s most valuable and threatened species and habitats. Yet, evidence shows that the present network fails to represent effectively the biodiversity of the region. 2. Priority areas for conservation of coastal and offshore biodiversity features in the Greek Ionian Sea were identified, based on the principles of systematic conservation planning (SCP). SCP is a transparent method for the design ofMPA networks and is considered more efficient and successful in representing the biodiversity of a region. 3. The prioritization software Marxan was used and three scenarios with different sets of targets for 17 (high and low priority) conservation features were produced. These scenarios explicitly took into account socio-economic factors expressed as a single cost metric, weighting different economic sectors in proportion to their contribution to the GDP of the region. Then results were compared with the existing Natura 2000 sites in terms of goal achievement, area requirements, and cost. 4. The solutions produced by the systematic approach demanded less area and lower cost to achieve the goals set, when the selection of all Natura 2000 sites was not forced. Existing Natura 2000 sites alone failed to achieve conservation goals for some EU priority and other important coastal and offshore habitats and species of the Mediterranean Sea. 5. It is suggested that the use of systematic conservation planning and related computational tools could benefit the selection of European marine priority areas, especially in the context of ecosystem-based marine spatial management.JRC.H.1-Water Resource

Proposing a network of marine protected areas in the central Ionian archipelagos and the Korinthiakos gulf

We identified priority areas for conservation to complement the existing marine protected areas (MPAs) in the Central Ionian Archipelagos and the Korinthiakos Gulf, Eastern Mediterranean, based on the principles of systematic conservation planning. This transparent method for the design of MPA networks is considered more efficient and successful in representing the biodiversity of a region. In order to apply systematic conservation planning we used the computational tool Marxan. Our objective was to provide adequate protection for the biodiversity of the study area while minimizing the impact on the socioeconomically important human activities in the area. We used 17 conservation features (species and habitats) as well as surrogates for three fishing sectors and tourism to estimate the socioeconomic cost, as inputs in our analyses. After classifying our features into two categories (high and low priority), we created three scenarios with different targets for our conservation features: low (60% and 20%), medium (70% and 40%) and high (80% and 60%). The low target scenario demanded the protection of 24% of the study area, the medium 34% and the high 45%. The proposed network of MPAs should be subjected to zoning and adaptive management, supported by solid monitoring and evaluation of previous management decisions.JRC.H.1-Water Resource

Inner ionian archipelagos and adjacent gulfs: ecological mapping for the needs of ecosystem-based marine spatial

Mapping of ecosystem components (natural and socioeconomic) is a prerequisite for ecosystem-based marine spatial management (EB-MSM). To initiate the process of EB-MSM in the Inner Ionian Archipelagos and adjacent gulfs, the main relevant ecosystem components were mapped based on existing spatial information and expert judgment. The natural components mapped included habitat types and species of conservation importance, according to national and European legislation and international agreements. Main human activities/pressures related to fisheries, aquaculture, tourism, and industry were also mapped. A substantial overlapping between ecological features and human activities was identified, confirming the need for a well planned approach of managing marine space in order to mitigate conflicts for marine resources and to conserve marine ecosystems and their associated goods and services.JRC.H.1-Water Resource

Ecological mapping and data quality assessment for the needs of ecosystem-based marine spatial management: case study Greek Ionian Sea and the adjacent gulfs

Mapping of ecosystem components (natural and socioeconomic) is a prerequisite for ecosystem-based marine spatial management (EB-MSM). To initiate the process of EB-MSM in the Greek Ionian Sea and the adjacent gulfs, the main relevant ecosystem components were mapped based on existing spatial information and expert judgment. The natural components mapped included habitat types and species targeted for conservation, according to national and European legislation and international agreements. Main human activities/pressures related to fisheries, aquaculture, tourism, and industry were also mapped. In order to assess the quality of data used to map ecosystem components and therefore take into consideration the inherent uncertainty, an assessment of 5 semi-quantitative data indicators based on a pedigree matrix was conducted. Through this qualitative approach we gained information related to the sources, acquisition and verification procedures, statistical properties, and temporal & geographical correlation, along with the collection process quality of the ecosystem components under study. A substantial overlapping between ecological features and human activities was identified, confirming the need for a well-planned approach to marine space management, in order to mitigate conflicts for marine resources and conserve marine ecosystems and their associated goods and services.JRC.H.1-Water Resource

Epidemiological characteristics and outcomes from 187 patients with COVID-19 admitted to 6 reference centers in Greece: an observational study during the first wave of the COVID-19 pandemic

Introduction: Epidemiological data from patients with COVID-19 has been recently published in several countries. Nationwide data of hospitalized patients with COVID-19 in Greece remain scarce. Material and methods: This was an observational, retrospective study from 6 reference centers between February 26 and May 15, 2020. Results: The patients were mostly males (65.7%) and never smokers (57.2%) of median age 60 (95% CI: 57.6–64) years. The majority of the subjects (98%) were treated with the standard-of-care therapeutic regimen at that time, including hydroxychlo-roquine and azithromycin. Median time of hospitalization was 10 days (95% CI: 10–12). Twenty-five (13.3%) individuals were intubated and 8 died (4.2%). The patients with high neutrophil-to-lymphocyte ratio (NLR) ( > 3.58) exhibited more severe disease as indicated by significantly increased World Health Organization (WHO) R&D ordinal scale (4; 95% CI: 4–4 vs 3; 95% CI: 3–4, p = 0.0001) and MaxFiO2% (50; 95% CI: 38.2–50 vs 29.5; 95% CI: 21–31, p < 0.0001). The patients with increased lactate dehydrogenase (LDH) levels ( > 270 IU/ml) also exhibited more advanced disease compared to the low LDH group ( < 270 IU/ml) as indicated by both WHO R&D ordinal scale (4; 95% CI: 4–4 vs 4; 95% CI: 3–4, p = 0.0001) and MaxFiO2% (50; 95% CI: 35–60 vs 28; 95% CI: 21–31, p < 0.0001). Conclusion: We present the first epidemiological report from a low-incidence and mortality COVID-19 country. NLR and LDH may represent reliable disease prognosticators leading to timely treatment decisions
