Fécondités individuelle et par recrue du homard européen Homarus gammarus (L.) des cotes françaises ArchiMer
Latrouite, Daniel; Morizur, Yvon; Raguenes, Gerard.
Several relationships between the fecundity and the weight or the size of females have been studied for three different (based on "eye-index") stages of incubation. The relationship between the average weight of eggs at the beginning of incubation and the size of the females shows that the egg size varies according to the female's size. Loss of eggs during incubation has been studied ; the average loss between the two extreme stages of incubation is around 27%. This is a lowered value of what accurs during the whole incubation period. Egg losses are greater for small females than for big females. The annual frequency of spawning and size at first maturity have been determined in for differents fishing effort than by the commercial size.

Further Development of Organic Farming Policy in Europe, with Particular Emphasis on EU Enlargement Organic Eprints
The EU-CEE-OFP project will identify how the complementary development of Organic Farming in both existing EU states, Switzerland, and in Central and Eastern European (CEE) Accession states can be fostered through policy design and innovation. Addressing the issue of complementarity requires a detailed knowledge of present conditions at both production and policy levels. At the production level, it is necessary to gather data on the structure and development of the OF sector. At the policy level, it is necessary to know the existing policy measures and their impacts on that structure in order to identify policy instruments that are successful or have the desired impacts. Having decided what is successful and from a scientific perspective desirable, one...

Genetic patterns in European Geometrid Moths revealed by the Barcode Index Number (BIN) System Naturalis
Hausmann, A.; Godfray, H.C.J.; Huemer, J.; Mutane, M.; Rougerie, R.; Nieukerken, E.J. van; Ratnasingham, S.; Hebert, P.D.N..
Background: The geometrid moths of Europe are one of the best investigated insect groups in traditional taxonomy making them an ideal model group to test the accuracy of the Barcode Index Number (BIN) system of BOLD (Barcode of Life Datasystems), a method that supports automated, rapid species delineation and identification. Methodology/Principal Findings: This study provides a DNA barcode library for 219 of the 249 European geometrid moth species (88%) in five selected subfamilies. The data set includes COI sequences for 2130 specimens. Most species (93%) were found to possess diagnostic barcode sequences at the European level while only three species pairs (3%) were genetically indistinguishable in areas of sympatry. As a consequence, 97% of the European...

Global warming and the change of butterfly distributions: a new opportunity for species diversity or a severe threat (Lepidoptera)? Naturalis
Ryrholm, N..
Global warming and the change of butterfly distributions: a new opportunity for species diversity or a severe threat (Lepidoptera)? In order to assess the influence of climatic changes on the distribution of insects, the ranges of nonmigratory European butterfly species have been studied. This study revealed that the northern limits of 32 (64%) of 52 species have expanded northwards during the 20th century. The southern limits of ten (25%) of 40 species have retracted northwards. The example of the Peacock butterfly (Inachis io) is given to illustrate the response to climatic changes of a species of which the range is not restricted by habitat choice. The northern limit of its range shows a considerable shift to the north during warm periods, and a...

Growing under the common agricultural policy: the institutional development of organic farming in Central and Eastern European countries from 2004 to 2012 Organic Eprints
Jahrl, Ingrid; Moschitz, Heidrun; Stolze, Matthias.
This paper analyses the institutional development of organic food and farming from 2004 to 2012 in six European countries: Austria, Bulgaria, Czech Republic, Estonia, Hungary and Romania. Based on document analysis and expert interviews with key informants on organic farming development in each country; similarities and differences in the development of the organic sector were analysed to evaluate if countries gaining accession to the EU at different times undergo similar organic sector development. Furthermore, the development of the organic sector was explored against the background of increasing involvement of the mainstream agricultural sector in organic farming development. To conclude, the uptake and support of organic farming by mainstream...

GROWING UNDER THE COMMON AGRICULTURAL POLICY - THE INSTITUTIONAL DEVELOPMENT OF ORGANIC FARMING IN CENTRAL AND EASTERN EUROPEAN COUNTRIES FROM 2004-2013 Organic Eprints
Moschitz, Heidrun; Jahrl, Ingrid.
The EU accession process has triggered the development of organic food and farming in countries accessing the EU. EU organic farming legislation needed to be transposed in these countries, and with that the regulations on organic farming support. Yet, such support has to find its way from the state to the single farmer, and farmers need markets and customers to sell their produce. Institutions need to be put in place that can act as channels for flows of knowledge and resources. The goal of this paper is to analyse the mid- to long-term impacts of the EU accession as external trigger for organic farming development. We will focus on the institutional development in selected countries that accessed the EU in 2004: Czech Republic, Hungary and Estonia,...

Growth Trends in European Organic Food and Agriculture Organic Eprints
Willer, Helga; Schaack, Diana; Bteich, Marie Reine.
In Europe today, organic agricultural land, operators4 and markets5, in almost all countries, continue to develop and grow. Furthermore in a global context Europe continues to be a forerunner in organic agriculture. This positive development in Europe and in particular in the European Union (EU) is due to a number of reasons, including strong consumer demand, legal protection and requirements for organic production and labelling as set out in EU and national legislation, and the development of private organic standards. In addition, policy support measures, such as conversion and maintenance payments for organic production and other relevant measures, provided for in most countries under the Common Agricultural Policy (CAP), Rural Development Programmes...

How organic farmers practice conservation agriculture in Europe Organic Eprints
Peigne, Joséphine; Casagrande, Marion; Payet, Vincent; David, Christophe; Sans, F. Xavier; Blanco-Moreno, José M.; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beechman, Annelies; Willekens, Koen; Luik, Anne; Matt, Darja; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among...

How to improve collection on organic agriculture in the countries of Central and Eastern Europe Organic Eprints
Willer, H.; Lernoud, J..
Annually, the Research Institute of Organic Agriculture FiBL collects data on key indicators of organic agriculture in European Union such as area, production and trade data among national data sources (for trade data) and Eurostat (for area, production and operator data; Eurostat 2018). Data are compiled in a MySQL database, and quality checks are carried out following the ORMACODE of the EUfunded OrganicDataNetwork (OrganicDataNetwork et al 2014), much of which is based on Eurostat’s Statistics Code of Practice (Eurostat 2011). Checks include the comparison against the previous year, the neighbouring countries, and the overall total. In case of inconsistencies, data providers are asked for clarification. FiBL publishes the data annually in collaboration...

Influence de l'azote et du phosphore sur la croissance et la toxicité de Prorocentrum lima (Ehrenberg) Dodge ArchiMer
Morlaix, Martine; Lassus, Patrick.
Very few attempts have been made in order to investigate the role of nutrients on cellular growth and toxin production in dinoflagellates associated with DSP (Diarrhetic Shellfish Poison). Some preliminary results are presented here, aiming at a better knowledge of inorganic nitrogen and organic phosphorus effects upon division rate and toxin content of Prorocentrum lima (PL2V spanish strain). Nitrogen have a positive effect on growth rate, up to a threshold value of 880muM.l-1. Above this threshold the rate decreases. There is no effect on toxin content since okadaic acid and DTX1 cell contents remain low (4.8 +/- 0.5 pg.cell.-1) and steady. Phosphorus effect upon division rate follows a non-linear relationship, whereas cellular toxic content is inversely...

Institutions and Policy Development for Organic Agriculture in Western Balkan Countries: a Cross-Country Analysis Organic Eprints
Hamade, Mr. Kanj; Midmore, Prof. Peter; Pugliese, Dr. Patrizia.
This paper uses a comparative qualitative approach to study the dynamic of institutional changes occurring in the organic movement, State agricultural institutions and policies, and in the organic supply chain, in six Western Balkan countries. It shows that the ‘Michelsen path’ (Michelsen et al., 2001) is identifiable in these countries, but in a different sequence. Additionally, a number of common trends are identified in the organic sector of the countries studied, leading to a converging trajectory in institutions and policy development for organic agriculture.

Is the machecoul fault the source of the ∼M6 1799 Vendée earthquake (France)? ArchiMer
Kaub, C; Geoffroy, Laurent; Bollinger, L; Perrot, Julie; Le Roy, Pascal; Authemayou, C.
The ∼M6 1799 Bouin earthquake is considered as one of the largest earthquakes to have struck Western France. However, the seismogenic source potentially responsible for this event remain marginally documented. We present results from a focused offshore-onshore multidisciplinary survey in its meizoseismal area in order to identify the fault segments that potentially ruptured during this earthquake. Based on macroseismic data and the geology, we focused our study on the so-called Machecoul Fault as a potential source of the 1799 Bouin event. Our survey includes extensive high-resolution seismic reflection, high resolution bathymetry and a one-year seismological survey. These data were combined with existing topography, onshore gravity data and drill data to...

Koberwitz (Kobierzyce): In the footsteps of Rudolf Steiner Organic Eprints
Paull, John.
“Now once again we have made a great step forward!” exclaimed Rudolf Steiner on the drive back from Koberwitz. Koberwitz (now Kobierzyce, Poland) can fairly be regarded as the birthplace of biodynamic agriculture. Rudolf Steiner delivered eight lectures at the Koberwitz Chateau (Schloss Koberwitz) in German in the summer of 1924 (7-16 June). There were 111 attendees, 30 women and 81 men, who came from six countries: Germany, Poland, Austria, Switzerland, France, and Sweden. The audience included farmers, estate managers, doctors, priests, teachers, artists, and engineers who all came to hear Steiner’s vision for agriculture. A witness observed “Seldom have I seen him so joyfully moved after the completion of a task as in this moment after the agricultural...
