Après une introduction sur la nature delavégétation, l'ouvrage traite dela variabilité delavégétation dans le temps: processus des changements, fluctuations, régénération et changements cycliques, successions primaires, successions secondaires
Various aspects of both allogenic and autogenic processes in riparian vegetationdynamics are discussed here; in particular how plants may promote bank stability and sedimentation, and river island development. Riparian restoration often fails

L'A. étudie les directions de recherche, les développements récents en paléoclimatologie à partir des données polliniques (cartographie synoptique), et les travaux concernant les processus sous-jacents dela réponse delavégétation aux changements
climatiques. Il donne les controverses, les hypothèses et les nouvelles approches sur la détermination des transformations delavégétation au Quaternaire (Holocène).

This research deals with approaches and concepts for a fruitful integration of dynamic models and GIS. It gives an overview of the current state of GIS and the characteristics of dynamic models. It is focussed on the concepts behind an integration
of dynamic models and GIS. The different case-studies in this work serve as examples of the techniques and concepts described earlier. These case-studies refer to water balance situations of large river basins with respect to their sensitivity to climatic
This article analyses species origins, dispersal, and island vegetationdynamics of the Kingdom of Tonga in the South Pacific. It demonstrates that species–area relationships are significant for all plant species and for ancient and modern
archipelagos of Samoa and Fiji. It concludes that plant dispersal spectra vary significantly according to island topography, geology,vegetation types, and plant species origins.

interglacial vegetation developed there after about 9000 yr B. P. Late-Quaternary vegetation has been in dynamic equilibrium, with a relatively constant flora, south of 33N on upland interfluves along the northern Gulf Coastal Plain, peninsular Florida
Defining the spatial and temporal limits of vegetational processes such as migration and invasion of established communities is a prerequisite to evaluating the degree of stability in plant communities through the late Quaternary. The interpretation
of changes in boundaries of major vegetation types over the past 20,000 yr offers a complementary view to that provided by migration maps for particular plant taxa. North of approximately 43N in eastern North America, continual vegetational disequilibrium has
resulted from climatic change, soil development, and species migrations during postglacial times. Between 33 and 39N, stable full-glacial vegetation was replaced by a relatively unstable vegetation during late-glacial climatic amelioration| stable

River, Italy. The study period (2004-2009) of increasing flow disturbance allows the exploration of vegetationdynamics within the river's active corridor under changing flow conditions. The analysis demonstrates the utility of ASTER data
for investigating vegetationdynamics along large fluvial corridors and reveals both spatial and temporal variations in the expansion, coalescence, and erosion of vegetated patches within the study reach. It is illustrated that the rate of growth of riparian trees
is crucial to their ability to contribute actively to river corridor dynamics.
