Europe counts marine life

Over 500 marine scientists are working together within the framework of MarBEF - a European network of excellence, which started in March 2004. Of all the seas, the European seas are among the most studied in the world. By bringing this expertise and knowledge together, MarBEF aims at a better understanding of long-term and large-scale distribution patterns and functionalities of biodiversity across marine ecosystems. To inventory this wealth of marine life, the European Register of Marine Species (ERMS), at this moment containing nearly 30,000 species names, is adopted and will serve as the reference list and taxonomic backbone within MarBEF. ERMS has been put into a relational database and will be maintained and regularly updated online by a consortium of taxonomic experts. The taxonomic register will be supplemented with biogeographic, ecological and socio-economic information, together with species illustrations, original descriptions and vernacular names. When available, links will be provided with other online species information systems. EurOBIS, the European node of the Ocean biogeographic Information System, is a distributed system that integrates individual datasets on biogeographic information into one large consolidated database and provides the end-user with a fully searchable geographic interface. EurOBIS already captures and freely communicates over 350,000 distribution data from 14,000 species, online. When combining these data with biological, physical, chemical and geologic data, our understanding of the ecosystem will greatly improve, resulting in better ecosystem-based management plans. The Flanders Marine Institute is taking a leading role in these major European data integrating projects within MarBEF and has recently developed online tools for ERMS and EurOBIS (http://www.marbef.org/data)

DIMAS Development of an integrated database for the management of accidental spills. Part 2. Global change, ecosystems and biodiversity - SPSDII: final report

DIMAS is a 2-year project executed by three Belgian partners (EURAS, VLIZ and Ghent University) and funded by the SPSD II research program of the Belgian Science Policy (BELSPO). Several shipping accidents in Belgian territorial waters, made the various government agencies involved aware of the need to develop tools to assess the risks and impact on marine resources in the case of an accidental release of hazardous substances. DIMAS aims at the protection of the North Sea and Western Scheldt in case of accidental spills from ships. In the present project, a relational database is developed, providing reliable, easy to interpret and up-to-date information on marine specific issues. The database contains the latest information on effects (acute and chronic), absorption, distribution, bioaccumulation/biomagnification, GESAMP hazard profiles and physico-chemical properties for a selection of priority substances and is publicly available (www.vliz.be/projects/dimas). The selection of the substances is based on criteria such as occurrence on priority lists, volumes transported over sea, frequency of involvement in accidental spills and frequency of transports over sea. The first beneficiaries of this database are the people directly involved in the first phase of a containment plan for an accidental spill. The final indirect beneficiaries are the general public (scientists, journalists, general public, etc.) who will be better informed about the potential impact to man and the environment

A census of fishes and everything they eat: how the Census of Marine Life advanced fisheries science

The Census of Marine Life was a 10-year, international research effort to explore poorly known ocean habitats and conduct large-scale experimentation with new technology. The goal of Census 2010 in its mission statement was to describe what did live in the oceans, what does live in the oceans, and what will live in the ocean. Many of the findings and techniques from census research may prove valuable in making a transition, which many governments have publicly endorsed, from single-species fisheries management to more holistic ecosystem management. Census researchers sampled continental margins, mid-Atlantic ridges, ocean floor vents and seeps, and abyssal plains and polar seas and organized massive amounts of past and new information in a public online database called the Ocean Biogeographic Information System (www.iobis.org). The census described and categorized seamount biology worldwide for its vulnerability to fishing, advanced large-scale animal tracking with acoustic arrays and satellite archival tags, and accelerated species identification, including nearshore, coral reef, and zooplankton sampling using genetic barcoding and pyrotag sequencing for microbes and helped to launch the exciting new field of marine environmental history. Above all, the census showed the value of investing in large-scale, collaborative projects and sharing results publicly

Ceramic production in the Kur River Basin (Fars, Iran) during the middle to late second millennium bce: a geochemical and technological characterization.

A total of 119 middle to late second millennium bce pottery samples from six sites in the Kur River Basin (Fars, Iran) were examined to characterize these ceramics and reconstruct their manufacturing technology and the origin of the primary materials. For this, a combined study of handheld XRF and thin‐section petrography was performed. The geochemical signatures of these ceramics were defined and interpreted in their archaeological and geological framework, resulting in the determination of different production processes and clay types used for four ceramic wares (Middle Elamite, Qaleh, Shogha and Taimuran) and the identification of possible outcrops used for Shogha–Taimuran production

Evidence for long-term sensitization of the bowel in patients with post-infectious-IBS.

Post-infectious irritable bowel syndrome (PI-IBS) is a common gastrointestinal disorder characterized by persistent abdominal pain despite recovery from acute gastroenteritis. The underlying mechanisms are unclear, although long-term changes in neuronal function, and low grade inflammation of the bowel have been hypothesized. We investigated the presence and mechanism of neuronal sensitization in a unique cohort of individuals who developed PI-IBS following exposure to contaminated drinking water 7 years ago. We provide direct evidence of ongoing sensitization of neuronal signaling in the bowel of patients with PI-IBS. These changes occur in the absence of any detectable tissue inflammation, and instead appear to be driven by pro-nociceptive changes in the gut micro-environment. This is evidenced by the activation of murine colonic afferents, and sensitization responses to capsaicin in dorsal root ganglia (DRGs) following application of supernatants generated from tissue biopsy of patients with PI-IBS. We demonstrate that neuronal signaling within the bowel of PI-IBS patients is sensitized 2 years after the initial infection has resolved. This sensitization appears to be mediated by a persistent pro-nociceptive change in the gut micro-environment, that has the capacity to stimulate visceral afferents and facilitate neuronal TRPV1 signaling

Choline-stabilized orthosilicic acid supplementation as an adjunct to calcium/vitamin D3 stimulates markers of bone formation in osteopenic females: a randomized, placebo-controlled trial.

BACKGROUND: Mounting evidence supports a physiological role for silicon (Si) as orthosilicic acid (OSA, Si(OH)4) in bone formation. The effect of oral choline-stabilized orthosilicic acid (ch-OSA) on markers of bone turnover and bone mineral density (BMD) was investigated in a double-blind placebo-controlled trial. METHODS: Over 12-months, 136 women out of 184 randomized (T-score spine < -1.5) completed the study and received, daily, 1000 mg Ca and 20 microg cholecalciferol (Vit D3) and three different ch-OSA doses (3, 6 and 12 mg Si) or placebo. Bone formation markers in serum and urinary resorption markers were measured at baseline, and after 6 and 12 months. Femoral and lumbar BMD were measured at baseline and after 12 months by DEXA. RESULTS: Overall, there was a trend for ch-OSA to confer some additional benefit to Ca and Vit D3 treatment, especially for markers of bone formation, but only the marker for type I collagen formation (PINP) was significant at 12 months for the 6 and 12 mg Si dose (vs. placebo) without a clear dose response effect. A trend for a dose-corresponding increase was observed in the bone resorption marker, collagen type I C-terminal telopeptide (CTX-I). Lumbar spine BMD did not change significantly. Post-hoc subgroup analysis (baseline T-score femur < -1) however was significant for the 6 mg dose at the femoral neck (T-test). There were no ch-OSA related adverse events observed and biochemical safety parameters remained within the normal range. CONCLUSION: Combined therapy of ch-OSA and Ca/Vit D3 had a potential beneficial effect on bone collagen compared to Ca/Vit D3 alone which suggests that this treatment is of potential use in osteoporosis.
