The goal of the study presented in the paper consists in understanding the vulnerability of economic systems to a modification of the hydrology due to climate change in the Meuse river basin. The latter extends over several regions in four different countries. A transnational approach is thus necessary to keep consistency throughout the international catchment. In this paper, we begin by illustrating how a strong collaboration between scientists and water authorities of the different parts of the basin has lead to a consistent approach for conducting flood risk analysis. Hazard modeling was conducted to get flood maps in the whole basin, considering various climate scenarios. In Wallonia, accurate hydraulic simulations were performed with the fully dynamic flow model WOLF2D entirely developed at the University of Liege (Erpicum et al., 2010). The outcomes of this inundation modeling constitute suitable inputs for the subsequent exposure analysis. The latter has been performed at a meso-scale using land use maps (CORINE) and geographic database (PLI), aggregated into a set of five damage categories. Recently developed damage functions, which are the key part of the vulnerability analysis, has been chosen in relation with the damage categories indentified in the exposure analysis. To determine the value of the assets, a monetary approach has been employed, with the purpose of assessing prices per square meter for each damage category. In this paper, the focus is set on comparing several approaches to calculate the specific price of the residential damage category in Wallonia, and to compare with an existing micro-scale approach (Ernst et al., 2010).

Flood risk analysis has been undertaken in Wallonia in the framework of several national and international research projects. The analysis relies on a micro-scale procedure, which involves • hazard modelling by means of detailed 2D inundation modelling • as well as processing of high resolution topographic and land use database for vulnerability modelling. The inundation modelling is conducted using the fully dynamic flow model WOLF 2D, entirely developed at the University of Liege. The model is run on a highly accurate DEM resulting from the combination of laser altimetry and, when available, sonar bathymetry. The typical grid spacing for the simulations is kept as low as 2m, which is definitely fine enough to represent the complex flows occurring at the scale of individual buildings and streets in urbanized floodplains. In this way, both the static and dynamic impacts of the flow may be characterized for all affected assets. This approach has been extensively applied since 2003 to issue inundation maps throughout the Walloon region based on detailed 2D flow modelling. Consequently, the outcomes of such detailed inundation modelling constitute suitable inputs for the subsequent exposure analysis, performed at a micro-scale using detailed land use maps and geographic database. Eventually, based on a multidisciplinary work, the procedure may incorporate social flood impact analysis and evaluation of direct economic damage to different categories of buildings and land types. Besides detailing the characteristics and performance of the hazard modelling, the presentation will describe the flow of data within the overall risk analysis procedure and will demonstrate its applicability by means of a case study, for which three different flood protection measures have been evaluated. These include rehabilitation of an old canal, recalibration of a floodplain as well as heightening of a protection wall by means of mobile dikes. The risk-oriented analysis of these flood protection measures has lead to findings which would not have arisen from a more standard hydraulic study such as based on a design flood. The flood risk analysis procedure is now readily available for large scale applications throughout the hydrographic basins in Wallonia and, in the near future, it will be combined with catchment modelling (accounting for climate change projections) to evaluate upstream flood mitigation measures as well as for the fine tuning of reservoir management rules in the framework of adaptation strategies to climate change.

Liege is located at the heart of the Meuse basin, which covers parts of France, Belgium, Germany and the Netherlands. Considering explicitly this transnational context when conducting flood risk analysis in the area of Liege sheds light on specific features and management opportunities which might otherwise be overlooked. Within a basin-wide collaborative approach, future flood risk was estimated along the course of the Meuse and adaptation measures were evaluated, particularly for the protection of the city of Liege.

Flowering is a hot topic in Plant Biology and important progress has been made in Arabidopsis thaliana toward unravelling the genetic networks involved. The increasing complexity and the explosion of literature however require development of new tools for information management and update. We therefore created an evolutive and interactive database of flowering time genes, named FLOR-ID (Flowering-Interactive Database), that is available freely at http://www.flor-id.org. The hand-curated database contains information on 306 genes and links to 1595 publications gathering the work of more than 4500 authors. Gene function and interactions within the flowering pathways were inferred from the analysis of related publications, included in the database and translated into interactive manually drawn snapshots.

The Becco locality (Liège province), belongs to the Theux tectonic window and represents a proximal, probably fluvial, environment corresponding to a channel infill. We present here a preliminary report of the fossil assemblage discovered at the locality. The Becco site has yielded a diverse flora of early seed plants including Moresnetia zalesskyi, Dorinnotheca streeli and Condrusia sp. This assemblage, characteristic of the Belgian Famennian, highlights the diversity of early spermatophytes in the country. Becco has also delivered a rich vertebrate fauna with antiarch, groenlandaspid and phyllolepid placoderms, diplacanthiform acanthodians, as well as actinopterygians and various sarcopterygians. The fossiliferous assemblage of Becco resembles those of several Devonian tetrapod- bearing localities, including that of Strud in Belgium, and could therefore provide a favorable palaeoecological setting in the search for early tetrapods.

1. L'Escargot de Bourgogne (Helix pomatia L.) héberge dans son tube digestif une flore chitinolytique abondante, sujette à des variations quantitatives et qualitatives. 2. En utilisant un milieu gélosé à la chitine, de pH 7 à 7,5, on peut isoler en moyenne; par gr. de contenu intestinal, 500.000 à 1 million de bactéries chitinolytiques. Cette flore bactérienne, dont les Actinomycètes, les Myxobactéries et les Champignons filamenteux chitinolytiques sont pratiquement absents, est très différente de celle du sol ou des végétaux, dans laquelle ces organismes dominent au contraire. Comme cela se passe chez les organismes supérieurs, les conditions propres au milieu intestinal de l'Escargot sélectionnent une flore bactérienne particulière. La plupart des microorganismes chitinolytiques, ingérés, à partir du milieu extérieur, restent dans l'incapacité de se multiplier dans le tube digestif, ou même y sont détruits. Inversément, dans les excréments expulsés, les bactéries chitinolytiques qui ont pullulé in vivo sont rapidement supplantées par d'autres microorganismes, semblables à ceux du sol. 3. La flore chitinolytique du tube digestif, mise en évidence sur milieu à la chitine ajusté au pH 5.5, qui est celui du milieu intestinal de l'Escargot, est plus abondante et plus constante que sur ce même milieu au pH7. Elle est surtout concentrée dans l'intestin moyen, entre l'estomac et la première anse intestinale. 4. Pendant les périodes de repos de l'Escargot (léthargie estivale), les bactéries chitinolytiques se déveloippent abondamment sur les parois du tube digestif et y restent adhérentes. En effet, les broyats aseptiques d'estomacs et d'intestins d'Escargots en estivation prolongée sont très riches en bactéries chitonolytiques (10 à 100 millions par gr. d'organes) tandis que le contenu intesqtinal lui-même est pauvre. Lorsque l'Escargot se réalimente, la richesse particulière des broyats en bactéroies chitinolytiques diminue rapidement. 5. La flore bactérienne chitinolytique intestinale est sujette à des variations qualitatives. Il existe cependant un type bactérien, constant chez tous les Escargots examinés, qui constitue en moyenne 70% des microorganismes chitinolytiques isolés. C'est un bâtonnet de petite taille, Gram-négatif, non sporulant, à extrémités arrondies, doué de motilité, formant à la surface des milieux gélosés à la chitine des colonies plates, rugueuses, transparentes, non pigmentées, à bords sinueux ou découpés, dont le centre punctiforme est légèrement bombé bet d'aspect muqueux. -- Depuis que l'on sait, par les travaux de Karrer et de ses collaborateurs, que le liquide intestinal de l'Escargot de Bourgogne contient une chitinase et une cellulase, on a coutume d'admettre, sans preuves expérimentales d'ailleurs, que ces deux ferments sont secrétés par l'hépatopancréas. Florkin et Lozet ont montré récemment qu'une cellulase est produite par certaines bactéries de l'intestin de l'Escargot, et que la multiplication in vitro de ces bactéries est favorisée par l'addition aux milieux de culture des sucs digestifs de l'hôte. Les présentes recherches montrent l'existence, dans le tube digestif de l'Escargot, d'une flore chitinolytique susceptible de sécréter une chitinase. [less ▲]
