| Forest management to a large extent determines the possible services that the forest can provide. Different objectives in forest management determine the rotation length and valuation of different stages in forest succession. We present a method of mapping potential forest management at 1-km resolution to inform policy, land use modeling, and forest resource projections. The presented method calculates the suitability of a location to different forest management alternatives based on biotic, abiotic, socioeconomic, and political factors. A sensitivity analysis of the resulting map to the data sources used was performed. This showed that the results are very sensitive to some data sources. The potential use of the map and the sensitivity to the availability... |

| Eliciting the economic benefits provided by protected areas is important in order to ensure that they are properly considered in policy and decision making. There are relatively few studies that provide a comprehensive overview of the economic benefits provided by European forest ecosystems, in spite of the large share of forests in the protected area system in most countries. An economic valuation of the ecosystem services supplied by the Hoge Veluwe forest in the Netherlands is presented. The Hoge Veluwe forest is one of the largest and most well-known protected areas in the country. The services included in the study are wood production, supply of game, groundwater recharge, carbon sequestration, air filtration, recreation, and nature conservation. A... |

| We present and analyze 10 case studies of participatory river-basin management that were conducted as part of the European HarmoniCOP project. The main theme was social learning, which emphasizes the importance of collaboration, organization, and learning. The case studies show that social learning in river-basin management is not an unrealistic ideal. Resistance to social learning was encountered, but many instances of social learning were found, and several positive results were identified. Moreover, 71 factors fostering or hindering social learning were identified; these could be grouped into eight themes: the role of stakeholder involvement, politics and institutions, opportunities for interaction, motivation and skills of leaders and facilitators,... |

| A Delphi survey involving experts in forest preference research was carried out to derive scores for the recreational value of 240 forest stand types across Europe. The survey was organized around four regional panels: Great Britain, Nordic Region, Central Europe, and Iberia. In each region, 60 forest stand types were defined according to five forest management alternatives (FMAs) on a continuum of management intensity, four phases of development (establishment, young, medium, and adult), and three tree species types (conifer, broadleaved, and mixed stands of conifer and broadleaved). The resulting scores were examined using conjoint analysis to determine the relative importance of the three structural attributes (FMA, phase of development, and tree... |

| A large number of occurrences of the highly pathogenic avian influenza (HPAI) H5N1 virus in wild birds were reported in Europe. The relationship between the occurrence pattern and environmental factors has, however, not yet been explored. This research uses logistic regression to quantify the relationships between anthropogenic or physical environmental factors and HPAI H5N1 occurrences. Our results indicate that HPAI H5N1 occurrences are highly correlated with the following: the increased normalized difference vegetation index (NDVI) in December; intermediate NDVI in March; lower elevations; increased minimum temperatures in January; and reduced precipitation in January. A predictive risk map of HPAI H5N1 occurrences in wild birds in Europe was generated... |

| Le congrès annuel de l'EAS (European Aquaculture Society) a rassemblé pendant 4 jours 531 chercheurs, producteurs et responsables institutionnels de 47 nationalités. Il a donné lieu à la présentation de 105 communications orales et de 274 posters. La thématique générale du congrès était construite sur le thème général suivant: Biotechnologies for quality. Il s'agissait de montrer que les biotechnologies, qui font parfois peur au consommateur comme au citoyen, constituent un outil privilégié de développement de l'aquaculture, y compris dans les aspects de développement durable. De fait, aujourd'hui, les attentes du grand public restent centrées autour des notions de qualité, sécurité, bien-être et santé animale. Le représentant de la Commission européenne a... |

| The "French Maritime Economic Data" report is periodically published by Ifremer since 1997. It presents an economic assessment of the French maritime activities, their position in the national economy and in the world competition, as well as the significance of non market public services. Maritime activities in the industrial sector are assessed using a standard metrics to facilitate the periodical update of the report: turnover, gross value added, employment, number of enterprises, exports. These indicators are expressed at national level. The public sector is described by annual budgets, number of staff and personnel costs, broken down into the different public policy functions. Regional indicators are provided on activities whenever relevant and... |

| This report includes a qualitative and descriptive approach of the oyster and mussel industries in the European Community. This report compares the structure of production, the marketsn the professional organisation, competition for the resource, legislation and support systemat the community levell. Technical and statistical datas are summarized to représent the structure of the industry, the trade flows and the main evolutions of the two industries in the EC. A summary of the county reports gives an overview of the present state of the industry in each country and suggest a first evaluation of constraints and prospects. [NOT CONTROLLDED OCR] |

| The so-called 8.2 ka event represents one of the most prominent cold climate anomalies during the Holocene warm period. Accordingly, several studies have addressed its trigger mechanisms, absolute dating and regional characteristics so far. However, knowledge about subsequent climate recovery is still limited although this might be essential for the understanding of rapid climatic changes. Here we present a new sub-decadally resolved and precisely dated oxygen isotope (5180) record for the interval between 7.7 and 8.7 ka BP 10(3) calendar years before AD 1950), derived from the calcareous valves of benthic ostracods preserved in the varved lake sediments of pre-Alpine Mondsee (Austria). Besides a clear reflection of the 8.2 ka event, showing a good... |

| The present distribution of the slipper limpet Crepidula fornicata in Europe is described in detail for each country, and an overview provided thanks to new information. Main observations of introduction and spread, obtained from the literature, are discussed. For most of them, we observe that both aspects are due to oyster harvesting and farming. ln the most heavily infested areas (France, England, the Netherlands), activities of dredging, harvesting and oyster farming have been disrupted. In France, these activities are so much hampered that treatment methods are now developed. |

| The first phase of the assessment of halieutic resources in the west of Europe was realised thanks to the Fisheries authority for the European Communities Commission. Different operations were carried out: - Creation of a data capture and extraction software. - Carrying out of a programmed trawling cruise in the area located between 48'35 N and the Capbreton canyon, from 15 m deep to 600 m. 132 30-minutes-stations were conducted and enabled the sampling of the main captured species as well as the collection of a large biological material. - Analysis of the trawling results through kriging. This method should facilitate the analysis of the distributions of the main halieutic populations. - Analysis of the yield and size/age distributions for the most... |

| We provide data on nutrient export for 28 rivers in southwestern Europe and analyze long-term changes in the context of anthropogenic pressures and regulation policies. Special attention is given to seasonal variations, because the integrated annual values that are usually provided do not allow us to establish comparisons with seasonal phytoplankton dynamics. The eutrophication risk associated with river inputs is addressed by means of an indicator (Index of Coastal Eutrophication Potential, ICEP, Billen and Garnier, Mar Chem 106:148–160, 2007). An overview of the temporal evolution and the intra-annual variability of the ICEP is discussed for specific rivers and integrated coastal regions. The annual dynamics of the eutrophication indicator is analyzed to... |
