On goodness-of-fit measure for dendrogram-based analyses.

Clustering methods are widely used tools in many aspects of science, such as ecology, medicine, or even market research, that commonly deal with dendrogram-based analyses. In such analyses, for a given initial dissimilarity matrix, the resulting dendrogram may strongly vary according to the selected clustering methods. However, numerous dendrogram-based analyses require adequate measurement for assessing of which of the clustering methods preserves most faithfully the initial dissimilarity matrix.

[Phytoplankton ecology along the French coasts: inter-site comparison].

The aim of this study is to characterize the large-scale geographical structures of microphytoplankton communities along French coasts. Once the temporal variability component shared by all sampled coastal sites was identified, and seasonal succession of microphytoplankton communities was described. A between-site analysis, using multiable comparison methods (STATIS), allowed the identification of three large areas according to the temporal variability patterns of microphytoplankton populations.

Triacylglycerol and fatty acid compositions of French virgin olive oils. Characterization by chemometrics.

There is no data concerning the fatty acid and triacylglycerol composition of French virgin olive oil. Thus, these compositions were determined using 564 samples coming from four olive harvests (1998-1999 to 2000-2001). Among these 564 samples, 372 came from the four main French cultivars (Aglandau, Cailletier, Picholine, and Salonenque) and from both of the oldest French protected designations of origin: "Nyons" (cv.
