A prior long-term and complex evaluation of the already available data on the geophysical prospecting during the first season work carried out at 2006, at the archaeological site of Tchinguiz Tepe of Termez, took place to decide the strategy to follow during the campaign of 2007. This previous evaluation of the information, on one hand, leaded to the decision to increase the geophysical prospecting at Tchinguiz Tepe, on the other hand, to decide the exact location of areas where the archaeological interventions.would carry out. The main objective at the beginning of this new season was to crosscheck the reliabilityof the measurements and, at the same time, to establish the unknown up to the present archaeologicaland chronological sequence of Tchinguiz Tepe. Meanwhile, the geophysical prospecting also wasextended to the outskirts of the city were the localisation of an unknown up to now Buddhist Monasterywas possible.

The International Pluridisciplinary Archaeological Expedition in Bactria (IPAEB) was created in 2006.The name underlines the international character of the team (which includes Uzbeks, Spanish, French, British and Greek members), the presence of specialists from various fields apart from archaeology and the fame of Bactria1.

This year the development of our project can be divided into two main clearly different parts, on one hand the laboratory work, where the sampled ceramic individuals has been prepared and analyzed and the elaboration of the data obtained during the excavation of 2007 has been finished and, on the other hand, the field work developed at the archaeological site during this specific year (2008).In the mark of the analytical work a significant number of ceramic individuals (144) from the different stratigraphical units from various areas of the excavation of Termez and Tchinguiz Tepe sampled duringthe new and previous field works has been archaeometrically characterized. This specific material includedindividuals dated into the Hellenistic and Sassanian period, which has been confirmed by C14dating upon organic samples.At the same time, in the mark of the field work of 2008 the archaeological record, already started tobe under study during the excavation of 2007, has been completed and two new archaeological recordshave been registered on of which is located in the area of Tchinguiz Tepe. For the archeological studythe information of the previous geophysical prospecting has been indisputably taken into considerationand the same methodology has been applied to crosscheck the latter archaeological results.

279 paires de bases du gène du Cytochrome b ont été séquencés pour 16 individus appartenant aux différentes formes chromosomiques de S. araneaus des Alpes occidentales, à S. coronatus et à S. granarius, laquelle a conservé un caryotype primitif. Trois clones principaux ont été identifiés: CC correspond à S. coronatus, CV caractérise la rae chromosomique Valais de S. araneaus, à l'exception des individus capturés aux Houches près de Chamonix, et CA est commun à tous les autres A. araneaus analysés. S. granarius ne montre que de très faibles différences avec le groupe CA, ce qui est en contradiction avec les données de la caryologie. Le fait que le clone CA soit caractéristique d'individus de la race Valais aux Houches, alors qu'une correspondance claire entre race chromosomique et clone de mtDNA est relevée dans les zones de contact entre la race Vaud (clone CA) et la race Valais (clone CB), suggère que les contact entre la race Vaud (clone CA et la race Valais (clone CB); suggère que les chromosomes Valais ont pénétré les populations Acrocentriques par introgression, tandis qu'au Haslital, la race Valais a progressé en repoussant la race Vaud sans qu'il y ait eu échange génétique

In August 2008, reactivation of the Little Salmon Lake landslide occurred. During this event, hundreds of conical mounds of variable size and composition formed in the deposition zone. The characteristics of these landforms are described and a potential mechanism for their formation is proposed. A preliminary slope stability analysis of the 2007 Mount Steele rock and ice avalanche was also undertaken. The orientation of very high persistence (>20 m long) structural planes (e.g., faults, joints and bedding) within bedrock in the source zone was obtained using an airborne-LiDAR digital elevation model and the software COLTOP-3D. Using these discontinuity orientation measurements, kinematic, surface wedge and simple three-dimensional distinct element slope stability analyses were performed.
