Daily precipitation concentration across Europe 1971-2010

Daily Precipitation Concentration Index (CI) was used in this paper to investigate the statistical structure of daily precipitation across Europe based on 530 daily rainfall series for the period 1971-2010. Annual CI shows a North- West to South-East gradient (excluding Turkey and Greece). The same gradient is also observed in winter, spring and autumn, while in summer the gradient is North-South. Highest annual and seasonal daily concentrations of rainfall were detected in the western Mediterranean basin, mainly along Spanish and French coastlands. Latitude and distance from the sea seems to play a major role on spatial CI distribution; at subregional scale also relief plays an important role. The Mann-Kendall test did not identify uniform significant pattern in temporal trend across Europe for 1971-2010 period. The only broad areas with increasing annual and seasonal CI values are located in northern and south-western France and northern coastlands of the Iberian Peninsula. This findings suggest that daily precipitation distribution has not significantly changed during the 1971-2010 over Europe.

Nesticus baeticus sp. n., a new troglobitic spider species from south-west Europe (Araneae, Nesticidae)

A new troglobitic species, Nesticus baeticus sp. n. (♂♀), inhabiting the karst landscapes of the high part of the Cazorla, Segura and Las Villas Natural Park (NE Jaén, Spain) where it has been found in 8 caves is diagnosed and described, its distribution and habitat are also analyzed.The new species belongs to the Iberian species group that includes Nesticus luquei, Nesticus lusitanicus and Nesticus murgis. Evolutionary relationships of the Iberian Nesticus species are discussed on the basis of morphological and molecular data (cox1 and rrnL).

L'état de la gouvernance des fédérations sportives européennes : enseignements et recommandations pour une "meilleure" gouvernance du sport en Europe

Cette thèse de Doctorat s'intéresse à la gouvernance du sport et plus particulièrement à la gouvernance des fédérations sportives européennes. Elle part du triple constat du manque de réflexion académique sur Popérationnalisation du concept de gouvernance du sport en unités de mesure, de l'intérêt croissant de l'Union européenne, du Conseil de l'Europe et de la Confédération suisse pour la réforme des organisations sportives internationales, ainsi que du faible attrait académique pour l'analyse d'un ensemble de fédérations sportives européennes. Elle a pour objectif principal de décrire l'état de la gouvernance d'un ensemble de fédérations sportives européennes (27) opérant en Europe. Cet objectif se décline en quatre questions principales : 1) Quelles sont les définitions et les dimensions de la gouvernance et de la gouvernance du sport dans une approche prescriptive ? 2) Comment mesurer la gouvernance du sport en Europe ? 3) Comment la gouvernance du sport est-elle mise en oeuvre par les fédérations sportives européennes ? 4) Comment améliorer la gouvernance du sport en Europe ? En reconnaissant la nature hybride d'une organisation sportive et optant pour les approches prescriptives de la gouvernance, la revue de la littérature présente les enseignements de la corporate governance, de la gouvernance des organisations à but non lucratif, de la gouvernance démocratique et de la gouvernance du sport. Celle-ci révèle notamment l'existence d'une constellation de prescriptions, applicables à un ensemble généralement non défini d'organisations sportives en Europe. La gouvernance du sport est ensuite définie par : « Les mécanismes par lesquels une organisation sportive de nature hybride agissant dans un système complexe et un environnement composés de multiples parties prenantes, notamment publiques et privées, est induite à modifier son comportement, ses structures et modes organisationnels afin de satisfaire leurs attentes multiples et divergentes tout en cherchant à préserver son autonomie ». Elle est déconstruite en trois dimensions, six composantes, et 39 indicateurs mesurant de façon originale quantitativement et qualitativement la mise en oeuvre de la gouvernance du sport. En nous appuyant sur une analyse de contenu et une série d'entretiens directifs, les résultats basés sur 1525 unités d'analyse montrent une image encourageante des fédérations sportives européennes, notamment en termes de formalisation des procédures démocratiques, et de publication d'informations biographiques. Cette image tend cependant à s'assombrir lorsque les indicateurs mesurent la transparence budgétaire et comptable, la mise en place d'une politique de développement environnemental, ou l'imposition d'une limite de mandat pour les membres du Conseil d'Administration. Ces résultats conduisent à la formulation de plusieurs recommandations conceptuelles, méthodologiques et empiriques permettant finalement de contribuer à une « meilleure » gouvernance du sport en Europe qu'actuellement (2014).

Defining ecologically relevant water quality targets for lakes in Europe

1. The implementation of the Water Framework Directive requires EU member states to establish and harmonize ecological status class boundaries for biological quality elements. In this paper, we describe an approach for defining ecological class boundaries that delineates shifts in lake ecosystem functioning and, therefore, provides ecologically meaningful targets for water policy in Europe. 2. We collected an extensive data set of 810 lake-years from nine Central European countries, and we used phytoplankton chlorophyll a, a metric widely used to measure the impact of eutrophication in lakes. Our approach establishes chlorophyll a target values in relation to three significant ecological effects of eutrophication: the decline of aquatic macrophytes, the dominance of potentially harmful cyanobacteria and the major functional switch from a clear water to a turbid state. 3. Ranges of threshold chlorophyll a concentrations are given for the two most common lake types in lowland Central Europe: for moderately deep lakes (mean depth 3–15 m), the greatest ecological shifts occur in the range 10–12 lg L 1 chlorophyll a, and for shallow lakes (<3 m mean depth), in the range 21–23 lg L 1 chlorophyll a. 4. Synthesis and applications. Our study provides class boundaries for determining the ecological status of lakes, which have robust ecological consequences for lake functioning and which, therefore, provide strong and objective targets for sustainable water management in Europe. The results have been endorsed by all participant member states and adopted in the European Commission legislation, marking the first attempt in international water policy to move from physico-chemical quality standards to harmonized ecologically based quality targets.

Upper Eocene-Lowermost Miocene charophyte succession in the Ebro Basin (Spain). Contribution to the charophyte biozonation in Western Europe

A charophyte succession has been established in nineteen sections and eight isolated outcrops from the Ebro Basin, ranging from the Priabonian ro the Aquitanian. Most assemblages were recovered fmm continuous sections and their abundance and diversity allow to define a new zonal scheme for the Upper Eocene-Lower Miocene of Europe. The new zonation includes nine subdivisions, based on the distribution of thirty-two species and directly correlated with the mammal standard levels. Changes in diversity, occurring mainly in the Middle and Upper Oligocene, have been related to climatíc variations. A new species, Chara sp. A. is also described and figured.

Prostate Cancer Unit Initiative in Europe: A position paper by the European School of Oncology.

The Prostate Cancer Programme of the European School of Oncology developed the concept of specialised interdisciplinary and multiprofessional prostate cancer care to be formalized in Prostate Cancer Units (PCU). After the publication in 2011 of the collaborative article "The Requirements of a Specialist Prostate Cancer Unit: A Discussion Paper from the European School of Oncology", in 2012 the PCU Initiative in Europe was launched. A multiprofessional Task Force of internationally recognized opinion leaders, among whom representatives of scientific societies, and patient advocates gathered to set standards for quality comprehensive prostate cancer care and designate care pathways in PCUs. The result was a consensus on 40 mandatory and recommended standards and items, covering several macro-areas, from general requirements to personnel to organization and case management. This position paper describes the relevant, feasible and applicable core criteria for defining PCUs in most European countries delivered by PCU Initiative in Europe Task Force.
