The investigations of Working Group 3 of COST Action E43 focused on assessing the ability of NFI's to report harmonized estimates of forest biodiversity indicators using NFI data. Four related factors motivated the investigations. Firstly, the importance of forest biodiversity for the economic, environmental, and social well-being of earth's civilizations is gaining wide international acceptance. Secondly, this acceptance has led to numerous international forest sustainability and biodiversity agreements that require periodic reports of estimates of indicators. Thirdly, the ability to report comparable estimates is impeded by the variety of sampling designs, plot configurations, selected variables, and measurement protocols used by the NFIs of different countries. Fourthly, the features of individual NFIs have evolved in response to unique ecological, economic, topographic, and climatic characteristics, and desire of the individual countries to retain the features. The general conclusion of these motivating factors is that apart from substantial standardization of NFIs, the best method for facilitating comparable reporting is to develop harmonization methods. Working Group 3 undertook a four-phase approach to developing methods for harmonizing estimates of biodiversity indicators using NFI data. The first phase entailed evaluating the importance of biodiversity variables and the feasibility of assessing them using NFI data. The conclusion of this phase was the selection of 17 biodiversity variables that were both important and feasible, grouping of them into seven essential features, and construction of common reference definitions for the variables. The second phase entailed evaluation of the agreement among NFIs with respect to the common definitions and measurement practices. The third phase entailed development of bridges (Stahl et al submitted) for converting estimates of forest biodiversity indicators obtained using national definitions to estimates consistent with the reference definitions. The fourth phase entailed construction of a common database of NFI data contributed by NFIs participating in COST Action E43 and testing of reference definitions and bridges developed by Working Group 3. The following chapters provide details and specific results for the four phases. [less ▲]

L’utilisation de l’allométrie hauteur-diamètre globale ou régionale en milieu tropical pourrait avoir des conséquences importantes dans les estimations de biomasse et des stocks de carbone. L’objectif de ce travail est d’identifier les variations de l’allométrie hauteur-diamètre au sein de deux types de forêts (forêt sempervirente et forêt semi-décidue) au sud du Cameroun et d’examiner leurs conséquences sur les estimations de biomasse. Le diamètre et la hauteur ont été mesurés sur un total de 521 arbres appartenant à 15 espèces et couvrant une gamme de diamètre de 10 à 240 cm. Une calibration des mesures non destructives et destructives de la hauteur a été réalisée sur 60 arbres. Dix modèles allométriques ont été ajustés sur ces données. Le meilleur modèle a été sélectionné avec Akaike Information Criterion (AIC). L’allométrie hauteur-diamètre au niveau des sites et entre les espèces a montré une tendance asymptotique (Modèle de Michaelis-Menten). Pour un même diamètre, les arbres étaient plus hauts dans les forêts semi-décidues que dans les forêts sempervirentes. Les différences de biomasse entre les deux types de forêts sont dues par les variations de l’allométrie hauteur-diamètre. Les variations de l’allométrie hauteur-diamètre sont donc d’une extrême importance dans les estimations de biomasse et des stocks de carbone des forêts denses humides tropicales d’Afrique centrale.

The legal regime of selective distribution agreements consists basically of four conditions enshrined in Article 175 of the Guidelines of the European Commission on Vertical Restraints. As such, any selective distribution scheme must comply with these four conditions to be exempted from the application of Article 101 TFEU. In our opinion, the interpretation generally accepted of the second condition, which touches upon the selection of the distributors on the basis of objective criteria, refers to a unilateral conduct, and not to an agreement between undertakings. In practice, this means that the scope of application of Article 101 TFEU has been artificially broadened and encompasses conducts which in fact constitute unilateral decisions of the undertakings.

Background: Crohn's disease (CD) is a polygenic multifactorial heterogeneous disease. Anti-Saccharomyces Cerevisiae antibodies (ASCA) correlate highly with CD and are present in 50-80% of patients. The reason for ASCA positivity or negativity in CD is unknown. The aim of our work was to analyse clinical, epidemiological and genetic characteristics in ASCA + or ASCA- CD patients. Methods : 113 patients with CD were tested for ASCA (IgA and IgG) by using a commercial kit (Medipan Diagnostica). Age, gender, systemic manifestations, familial form of disease, age at diagnosis, location and behaviour of the disease, smoking habit as well as genotyping for -308 TNF gene polymorphisms were determined. Results : 38.9% CD patients were negative for both IgA and IgG ASCA while 61.1% were ASCA positive (respectively IgA and IgG : 31.9%; IgA only : 9.7%; IgG only : 19.5%). The only significant difference between ASCA+ and ASCA- patients was for smoking habit : there were 29% smokers in ASCA+ versus 50% in ASCA- CD patients (P = 0.03). This low proportion of smokers was more prominent in ASCA IgA+ patients than in isolated ASCA IgG+ patients (25.6% versus 45.5%) and was minimal in patients with high titers of ASCA IgA (0/8). Logistic regression showed smoking habit still borderline for significance (P = 0.057). Conclusions : Our results suggest a negative association between smoking and ASCA positivity in CD. This association was more prominent for ASCA IgA+. It indicates that smoking habit should be taken into account when analysing ASCA status in CD patients and may suggest an influence of smoking on immunization against intestinal material. [less ▲]

The colossal negative magnetoresistance Delta rho observed in La0.6Y0.1Ca0.3MnO3 at B=1 T shows an unusual, nearly perfect symmetry (around the peak temperature T-0=160 K), suggestive of a Curie-Weiss-dominated transport mechanism in this material both above and below the field-dependent Curie temperature T(C)equivalent to T-0. Attributing this symmetry to strong magnetic fluctuations below T-C (which are triggered by the Y substitution and cause a "bootstrap" destruction of the ferromagnetic phase), the data are interpreted in terms of the nonthermal spin hopping and magnetization-dependent charge carrier localization scenario leading to Delta rho=-rho(s)(1-e(-gamma M2)), with the magnetization M(T,B)=CB/\ T-T-C(B)\(nu). The separate fits through all the data points above and below T-C yield C(+)similar or equal to 2C(-) and nu(+)similar or equal to nu(-)similar or equal to 1, in agreement with the predictions of the Landau mean-field theory.
