The natural background levels of metallic trace elements (MTEs) in cultiva-ted soils should be known in order (i) to understand the processes in which MTEs are involved and (ii) settle a reference system dedicated to the the ap-praisal of agricultural practices, to the detection of contaminations, or to the time-course follow-up of regional values. A methodological framework has thus been set up to evaluate the importance of natural driving factors, the pe-dogeochemical background, of the spatial distribution of MTEs in soils and also to compare the current levels of MTEs content in agricultural soils from the Loamy Region with natural values. As main results from the study of parent materials, (i) lithological units are now characterized with element content signatures, (ii) the prominent part of clay, total iron, and total aluminium contents as driving factors of the content in MTEs has been measured, and (iii) the geographical homogeneity as well as the absence of spatial continuity of the cover loessic parent material have been showed up. The relations between MTEs and driving variables have been confirmed through the study of the influences of pedogenesis factors on the vertical and lateral differenciations of MTEs content in soils. It was also demonstrated that taking into account the natural volumes of soils when sam-pling facilitates the interpretation of the results and allows finer estimations of the MTEs content, even in homogeneous context. The reference values about natural and usual content in MTEs for various soil horizons that are proposed reveal a relatively weak level of man-made contamination in the Loamy Re-gion. It has also been shown that a regional reference system dedicated to the detec-tion of local contaminations gains in relevance as it integers ancillary datas as well as the local specificities of small natural regions. The spatial variability of MTEs content has been evaluated through various cartographic approaches which led to the conclusion that the Soil Map of Belgium is an extremely worthy document for geochemical mapping.

The release of mobility constraints has facilitated urban sprawl, i.e. the increasing spatial dissociation between urban cores and implantation sites of households and economic activities. The aim of this paper about the Walloon part of the Brussels metropolitan region is to analyse how housing market constraints reinforce the trend towards residential sprawl. Based on an analysis of the financial accessibility to both, the market for new housings and the market for pre-existing housings, it is here the influence of the price level decreasing with the distance from Brussels which is taken into account. Due to their limited financial resources and to this price gradient, many households are obliged to settle on remote sites in order to acquire their property goods. In relation to this phenomenon, it appears that, from a spatial as well as from a social point of view, the Brussels urban system is not able to settle the metropolitan growth on an adapted way. Indeed, new residential locations reinforce the increasing dissociation between work places and living places, which leads to a useless increase in mobility costs as well as a serious accentuation of socio-spatial segregations.

En Belgique la pratique de la prospective, entendue sous la forme d'exercices découlant des méthodes appelées dans les pays anglo-saxons «foresight», n'est pas encore à proprement parler devenue monnaie courante. Toutefois, diverses initiatives, tant au niveau fédéral qu'a différents niveaux régionaux ou subrégionaux ont vu le jour ces dernières années11. S'il existe un point commun entre ces exercices, de l'avis même de ceux qui ont eu à les mettre en oeuvre, c'est sans doute la difficulté de trouver un consensus sur les méthodes et les techniques à utiliser. Les décideurs ou les experts sont confrontés au même problème: aujourd'hui il n'existe pas un paradigme unique de la prospective mais une multitude de pratiques plus ou moins rigoureuses. Ce guide se donne pour objectif d'éclairer le lecteur sur le paysage de ces différentes pratiques en mettant l'accent sur les conditions possibilité de leur mise en oeuvre et leurs avantages respectifs. Nous espérons que ces quelques balises permettront à tous ceux qui souhaitent se lancer dans l'aventure de la prospective, à quelque niveau que ce soit en Belgique, d'éviter les errements que leurs prédécesseurs ont parfois connu et en tout cas leur permettront de faire les choix les plus opportuns en connaissance de cause.

The morphology and spatial distribution of the different types of neuromasts encountered on the trunk lateral line of the sea bass (Dicentrarchus labrax) were examined using scanning electron microscopy. The sea bass trunk lateral line exhibits a complete straight pattern. In their basic features, the two types of neuromasts present, canal and superficial, resemble what has been described in other fishes. They are similar in their general cellular organization but differ in sizes, and shapes, as well as in the densities and lengths of their hair bundles. However, the sea bass trunk lateral line distinguishes itself in several ways. For instance, the pores of the canal segments are partially obstructed due to the overlap of scales throughout the trunk. Moreover, based on the density and length of the hair bundles, two distinct areas, central and peripheral, could be distinguished within the maculae of canal neuromasts. Their cupulae are also peculiar as they possess two wing-like extensions and that their central core appears to be organized in layers instead of columns. In addition, the superficial neuromasts, up to 6 per scale, are either round or elliptical and seem to be distributed serendipitously. Finally, within the maculae of both types of neuromasts, a significant number of hair bundles do not follow the two-directional polarity pattern usually described. Although some hypotheses are proposed, the influence of these characteristics in terms of signal encoding and fish behavior is yet to be understood. [less ▲]
