De nombreux travaux montrent que les évolutions urbaines contemporaines s’inscrivent dans un processus de recomposition des villes induit par la mobilité facilitée et par la banalisation de la conduite automobile. Dans le cadre de cet article, nous traitons cette thématique en étudiant, pour le contexte belge, comment le relâchement des freins à la mobilité interfère avec les logiques résidentielles des familles en formation. Un bilan sur la situation contemporaine est d’abord dressé. Nous y présentons les principaux liens entre choix résidentiels, classes d’âges et parcours de vie. Nous y analysons aussi les relations entre, d’une part, le constat de l’étalement périurbain et, d’autre part, la pression foncière à laquelle les ménages en formation ont à faire face. En seconde partie, la situation contemporaine est confrontée aux évolutions des cinq dernières décennies. Ces analyses réalisées pour la région urbaine de Liège permettent de combiner les trois grilles explicatives du moment du cycle de vie, de l’effet du renouvellement des générations et de l’impact du contexte socio-économique. De ce travail, nous relevons que la mobilité facilitée conduit à dilater les inscriptions démographiques. Comme les groupes sociaux, les groupes démographiques sont, en effet, de plus en plus spatialement ségrégés dans une région urbaine très largement recomposée par la mobilité automobile. [less ▲]

Le livre reprend 10 contributions issues d'un colloque organisé en 2004 à Bruxelles. Il aborde les relations entre mobilité et temporalité qui conjuguent deux préoccupations contemporaines s'alimentant l'une l'autre. D'une part la question des mobilités et d'autre part la question du temps (du discours sur son accéleration à celui de son individualisation). [less ▲]

This study performed in the Patapedia River (Quebec, Gaspesie) was designed to examine the space utilization and mobility patterns of individual Atlantic salmon parr over short time scales with frequent detections of position. In August 2004, n = 7 radio-tagged Atlantic salmon parr were located every 20 min during 10 tracking periods chosen to take into account the dawn, day, dusk and night periods. Parr showed important inter individual variability in space utilization and mobility patterns, occupying large home ranges (123 to 5602 m(2)) and sometimes migrating 2 km upstream in the river. No differences were observed in the mean distance travelled among the four daily periods by individual fish, but the estimated home ranges utilized during the four daily periods overlapped only partially, demonstrating that parr partly occupy different areas of the river during different parts of the daily cycle. The results suggest that an intense survey on a small number of fish may contribute to a complementary comprehension of space utilization and mobility patterns of Atlantic salmon parr when viewed in association with results from studies surveying larger number of fish at lower frequency.

Vertical matter transfer processes (bioturbation and <2μm translocation) in soils and their dynamics are up to now poorly constrained although they are responsible for the temporal evolution of the ecosystem services. In order to better constrain and quantify these processes, a kinetic quantification of the involved transfers based on vertical profiles of 210Pb (xs), 10Be and 137Cs has been developed for Luvisols in which soluble transfers could be neglected. The range of applicability of this type of approach was nevertheless not tested. In this work, we analyzed 210Pb (xs), 10Be and 137Cs in soils exhibiting gradients of organic matter, pH and < 2 μm fraction (Podzol, Andosol Ferralsol, Leptosol). Acidic soils and large organic matter contents were considered. The depth distribution of the studied isotopes was then interpreted as a function of the organic matter content, the soil pH and its < 2 μm fraction. This demonstrates that 10Be and 137Cs losses occur under soluble form in the Podzol, especially under forest, more acid, for the latter. Soluble 10Be transfers were also identified in the Andosol when they were considered as negligible in the Leptosol. For 210Pb (xs), soluble transfers are also probable for soils with pH less than 5.5 (Andosol and Ferralsol) and strong affinity for organic matter has been demonstrated. Thus, under acidic conditions and low < 2 μm fraction, soluble transfer cannot neglected anymore. [less ▲]

Adult roach Rutilus rutilus (L.) (N = 24; 19.9-36.1 cm FL) from three highly fragmented Belgian rivers were tagged with surgically implanted radio transmitters. Their seasonal movements were observed from March to August 2004 (circum reproduction period) in river stretches delimited by two physical barriers. In the three rivers, roach displayed similar patterns of movements which were mainly influenced by the date of observation (movements increased in late April-May) and water temperature (travel distances were more important when water temperature ranged between 10 degrees C and 14 degrees C). Roach sometimes cleared physical obstacles. The mean distances travelled in each river were relatively short (max. 2.5 km) and mainly influenced by the length of the study reach, which was delimited by physical barriers. [less ▲]
