Morphological description of the southeastern Cyprus outer shelf and slope regions (eastern Mediterranean)

We present here the first results of the analysis and interpretation of the swath bathymetry and side scan sonar data collected along the southeastern outer shelf and upper slope regions of the Cyprus insular margin (offshore Cape Greco). The resultant bathymetric model and the derivatives (e.g.: slope, aspect, benthic position index) are presented and analyzed in order to describe the morphology of the seabed and the main geomorphological features through quantitative indicators including morphometric indexes and statistical descriptors. The presence of deep sea coral communities (Dendrophylia ramea) in a particular location of the surveyed area is also discussed and tentatively related to the landscape morphology where the colonies are settle

Curling: Content-ubiquitous resolution and delivery infrastructure for next-generation services

CURLING, a Content-Ubiquitous Resolution and Delivery Infrastructure for Next Generation Services, aims to enable a future content-centric Internet that will overcome the current intrinsic constraints by efficiently diffusing media content of massive scale. It entails a holistic approach, supporting content manipulation capabilities that encompass the entire content life cycle, from content publication to content resolution and, finally, to content delivery. CURLING provides to both content providers and customers high flexibility in expressing their location preferences when publishing and requesting content, respectively, thanks to the proposed scoping and filtering functions. Content manipulation operations can be driven by a variety of factors, including business relationships between ISPs, local ISP policies, and specific content provider and customer preferences. Content resolution is also natively coupled with optimized content routing techniques that enable efficient unicast and multicast-based content delivery across the global Internet

The Deep‐water corals of Cyprus: Environmental settings and ecological features (CYprus Cold‐corals Levantine SeA, Eastern MEditerraneaN: CYCLAMEN)

The recently started research project CYCLAMEN (CYprus Cold-corals Levantine SeA, Eastern MEditerraneaN), will conduct the first detailed study of cold-water coral communities in eastern Cypriot waters. Cold-water coral habitats have been found during exploratory surveys. The 2-yr long project will include the environmental characterization of the area, as well as the study of the spatial distribution of cold-water coral communities. In addition to the study of the biology of the coral species, genetic and eco-physiological studies will be included. This project is the first of its kind in Cyprus and will additionally have an associated scientific outreach programme in order to bring these ecosystems, still poorly known, to the general public. The project is led by the Spanish Institute of Oceanography (IEO), and relies on the participation of research Institutions in Cyprus: The Cyprus Institute (CyI) and the NGO Enalia Physis Environmental Research Centre (EPERC); France: Aix-Marseille University – Mediterranean Institute for Biodiversity & Ecology (AMU-IMBE); Greece: The Hellenic Centre for Marine Research (HCMR); Mónaco: Centre Scientifique de Monaco (CSM); United Kingdom: National Oceanography Centre (NOC), and Spain: Universitat de Barcelona (UB). Here we present the conceptual frame of the project, the background knowledge and the first obtained results in the oceanographic cruise carried out in summer 2015

Tackling the lionfish invasion in the Mediterranean. the EU-LIFE RELIONMED Project: progress and results

The lionfish invasion in the Western Atlantic has been characterised as one of the most ecologically harmful marine fish introductions to date; associated with habitat modifications, and severe impacts on native communities. In the Mediterranean, lionfish followed similar expansion trends and raised significant concerns among the scientific community due to its potential to cause devastating ecological and socioeconomic impacts. The coastal ecosystems of Cyprus, near the Suez Canal, are amongst the first Mediterranean waters to be affected by the lionfish invasion. Cyprus sentinel location offers therefore, an ideal site for the development of an early warning and rapid response system of marine bioinvasions. RELIONMED (Preventing a LIONfish invasion in the MEDiterranean through early response and targeted REmoval) is a four-year project, funded by the EU LIFE instrument, aiming to make Cyprus the first line of defence against the invasion of lionfish in the Mediterranean. The project has started successfully on September 2017 with a number of early (preparatory) project actions including stakeholder consultation and baseline assessment of social awareness, biological analyses of a small lionfish sample, and the development of a lionfish risk assessment following the guidelines of the Regulation 1143/2014 to include the species in the EU IAS priority list. Forthcoming project’s actions strongly rely on citizen scientists’ and stakeholders’ participation and RELIONMED aims to develop the capacity and tools for control of lionfish, particularly in priority habitats. Preliminary results such as early maturity, high growth rates, generalist diet, and reproduction throughout the year indicate that lionfish can become a ferocious invader for the basin and RELIONMED calls for regional collaborations and coordinated management measures against lionfish invasion in the basin

The Case of Lionfish (Pterois miles) in the Mediterranean Sea Demonstrates Limitations in EU Legislation to Address Marine Biological Invasions

The European Regulation (EU) 1143/2014 on Invasive Alien Species entered into force in 2015, with the aim to fulfill regional and international biodiversity goals in a concerted manner. To date, the Regulation listed 66 Invasive Alien Species (IAS) that are subject to legal controls. Only one of these is marine. A recent lionfish (Pterois miles) invasion has been closely monitored in the Mediterranean and a detailed risk assessment was made about the profound impacts that this invasive fish is likely to have on the fisheries and biodiversity of the region. In 2016–21, lionfish rapidly became dominant predators along Eastern Mediterranean coasts, yet the process for their inclusion on the EU IAS list has been lengthy and is ongoing. There is an urgent need to learn from this experience. Here, we recommend improvements to the Regulation 1143/2014 and the risk assessment process to protect marine ecosystems and secure the jobs of people that rely on coastal resources.</jats:p

Tracking a mass mortality outbreak of pen shell Pinna nobilis populations: A collaborative effort of scientists and citizens

A mass mortality event is devastating the populations of the endemic bivalve Pinna nobilis in the Mediterranean Sea from early autumn 2016. A newly described Haplosporidian endoparasite (Haplosporidium pinnae) is the most probable cause of this ecological catastrophe placing one of the largest bivalves of the world on the brink of extinction. As a pivotal step towards Pinna nobilis conservation, this contribution combines scientists and citizens' data to address the fast- and vast-dispersion and prevalence outbreaks of the pathogen. Therefore, the potential role of currents on parasite expansion was addressed by means of drift simulations of virtual particles in a high-resolution regional currents model. A generalized additive model was implemented to test if environmental factors could modulate the infection of Pinna nobilis populations. The results strongly suggest that the parasite has probably dispersed regionally by surface currents, and that the disease expression seems to be closely related to temperatures above 13.5 degrees C and to a salinity range between 36.5-39.7 psu. The most likely spread of the disease along the Mediterranean basin associated with scattered survival spots and very few survivors (potentially resistant individuals), point to a challenging scenario for conservation of the emblematic Pinna nobilis, which will require fast and strategic management measures and should make use of the essential role citizen science projects can play

Plasma leptin and insulin-like growth factor I levels during acute exacerbations of chronic obstructive pulmonary disease

<p>Abstract</p> <p>Background</p> <p>Recent studies have provided evidence for a link between leptin and tumor necrosis factor-alpha (TNF-α). Insulin-like growth factor I (IGF-I) mediates the metabolic effects of growth hormone (GH). The GH axis is believed to be suppressed in chronic obstructive pulmonary disease (COPD). The aim of this study is to find out whether acute exacerbations of COPD are followed by changes in plasma leptin and insulin-like growth factor I (IGF-I) levels and furthermore, whether these changes are related to systemic inflammation.</p> <p>Methods</p> <p>We measured serum leptin, IGF-I, TNF-α, interleukin 1β (IL-1β), interleukin 6 (IL-6) and interleukin 8 (IL-8) levels in 52 COPD patients with acute exacerbation on admission to hospital (Day 1) and two weeks later (Day 15). 25 healthy age-matched subjects served as controls. COPD patients were also divided into two subgroups (29 with chronic bronchitis and 23 with emphysema). Serum leptin and IGF-I were measured by radioimmunoassay and TNF-α, IL-1β, IL-6 and IL-8 were measured by ELISA.</p> <p>Results</p> <p>Serum leptin levels were significantly higher and serum IGF-I levels significantly lower in COPD patients on Day 1 than in healthy controls (p < 0.001). A positive correlation was observed between leptin and TNF-α on Day 1 (r = 0.620, p < 0.001). Emphysematous patients had significantly lower IGF-I levels compared to those with chronic bronchitis both on Day 1 and Day 15 (p = 0.003 and p < 0.001 respectively).</p> <p>Conclusion</p> <p>Inappropriately increased circulating leptin levels along with decreased IGF-I levels occured during acute exacerbations of COPD. Compared to chronic bronchitis, patients with emphysema had lower circulating IGF-I levels both at the onset of the exacerbation and two weeks later.</p
