    Stakeholder perceptions in fisheries management - Sectors with benthic impacts
    Soma, K. ; Nielsen, J.R. ; Papadopoulou, N. ; Polet, H. ; Zengin, M. ; Smith, C.J. ; Eigaard, O.R. ; Sala, A. ; Bonanomi, S. ; Burg, S.W.K. Van Den; Piet, G.J. ; Buisman, E. ; Gümüş, A. - \ 2018

    The capture fishing sector causes direct and indirect impacts on benthic habitats and associated fauna and flora. Effectiveness of new mitigation measures depends on fishermen's perceptions; their acceptance of, and compliance to, those measures. Accordingly, by means of Advisory Councils (ACs), fisheries stakeholders are encouraged by the Common Fisheries Policy (CFP) reform to contribute to policy formulations. Still, the CFP reform remains unclear about how to possibly incorporate perceptions of specific conservation measures and objectives in practice. Against this background, this article aims at exploring a systematic multi-criteria approach that provides information about stakeholder preferences for objectives reflecting on what is more important to aim for (‘what’), mitigation measures as strategies for reaching their objectives (‘how’), and accountability options that can enhance trust in the people who carry out management (‘who'). The approach applies a pairwise comparison approach to elucidate the stakeholder preferences, and to estimate the relative importance of the different options. It is conducted in the Black Sea, the Mediterranean Sea, the Baltic Sea, and the North Sea. The outcomes of the questionnaire survey succeed in transparently reflecting a diversity of preferences. It is advised that in order to inform the CFP, the ACs develop a user-friendly attractive online version of this approach that can reach multiple stakeholders across Europe and facilitate updates on a continuous basis. In this way the ACs could better facilitate bottom-up participation in fisheries management by representing a wide range of stakeholder perceptions.

    Ecoinformatics - European vegetation archive (EVA) - Grassland vegetation - Phytosociology - Relevé - Romanian grassland database (RGD) - Splot - Turboveg - Vegetation classification - Vegetation-plot data
    This report describes the Romanian Grassland Database (RGD), registered under EU-RO-008 in the Global Index of Vegetation-Plot Databases (GIVD). This collaborative initiative aims to collect all available vegetationplot data (relevés) of grasslands and other open habitats from the territory of Romania to provide them for science, nationally and internationally, e.g. via the European Vegetation Archive (EVA) and the global database "sPlot". The database mainly contains vegetation-plots from not only wet, mesic, dry, saline, alpine and rocky grasslands, but also other vegetation types like heathlands, mires, ruderal, segetal, aquatic and cryptogamdominated vegetation. Currently, 21,685 relevés have mainly been digitised from literature sources (90%), while the remainder comes from individual unpublished sources (10%). We report on the background and history of the RGD, explain its "Data Property and Governance Rules" under which data are contributed and retrieved, and outline how the RGD can contribute to research in the fields of vegetation ecology, macroecology and conservation.

    Biological traits - European shelf - Infauna - Unimpacted assemblages
    There is an implicit requirement under contemporary policy drivers to understand the characteristics of benthic communities under anthropogenically-unimpacted scenarios. We used a trait-based approach on a large dataset from across the European shelf to determine how functional characteristics of unimpacted benthic assemblages vary between different sedimentary habitats. Assemblages in deep, muddy environments unaffected by anthropogenic disturbance show increased proportions of downward conveyors and surface deposit-feeders, while burrowing, diffusive mixing, scavenging and predation traits assume greater numerical proportions in shallower habitats. Deep, coarser sediments are numerically more dominated by sessile, upward conveyors and suspension feeders. In contrast, unimpacted assemblages of coarse sediments in shallower regions are proportionally dominated by the diffusive mixers, burrowers, scavengers and predators. Finally, assemblages of gravelly sediments exhibit a relatively greater numerical dominance of non-bioturbators and asexual reproducers. These findings may be used to form the basis of ranking habitats along a functional sensitivity gradient.
    Growth of European eel in a Turkish river at the southern-eastern limit of its distribution
    Yalcin-Ozdilek, S. ; Gumus, A. ; Dekker, W. - \ 2006
    The bulletin of the European Ichthyological Society 2 (2006)2. - ISSN 1565-7396 - p. 55 - 64.
    European eel, Anguilla anguilla L., has a wide distribution from polar to arid climates. The growth and sex in eels from the River Asi, which is in the most arid region of the species distribution, and at a temperature of 21-27 ºC close to the experimentally determined optimum for the eel were examined. A total of 315 European eels were collected between January 1997 ¿May 1998 and April 2003. Growth was fast, with a high asymptotic length. Temperature is the main factor driving to growth; apparently, growth does not cease during the hot, arid summer. Since these fastest growing stocks will be of major significance for overall dynamics of the whole population, further studies of these southern eels will be required.
