- AbstractBiologists have distinguished 3 phytogeographical areas in the alpine range: the external Alps, intermediate and internal Alps; however, their respective limits have not yet been determined. This problem has been studied in the Dauphine Alps, on a latitude with Grenoble. The interpretations put forward are based on a statistical analysis of 274 phytoecological samples and over 300 herbaceous and ligneous species. These samples involved beech-fir and fir-spruce stands and were distributed along a W-E transect from Chartreuse to Briancon. This selection was made due to the fact that the beech, the fir and the spruce are heavily represented in the Dauphine Alps and constitute the main species found in most mountainous populations. FAA (factorial agreement analysis) and HAC (hierarchic ascending classification) carried out on the total data resulted in the determination of phytogeographic characteristics of each type of population. In addition, sample analysis via the mutual information method resulted in a characterization of the various sectors and subsectors using herbaceous species with a well established distribution and ecology. The validity of the divisions which the authors had proposed in a former study is discussed (Cadel and Pautaou, 1984): the division of the internal Alps into 2 subsectors is corroborated by multidimensinal analysis; however, the division of the intermediate Alps into 2 subsectors is not as clear-cut.
