On the basis of two parallel data sets refering to phenological events in open scrubs and pastures at two sites (Balaguer and Vic), the authors present a comprehensive report of the phenology of these Mediterranean communities. Four main phenophases (vegetative growth, flowering, fruiting and resting) were recorded monthly in 11 communities over 15 months. The results allow comparisons to be drawn between localities and communities, both at community and species levels, and to consider the effects of contemporary climatic data. This yielded useful information on general trends and on the particular responses of each community type to their corresponding constraints.

The first part of a general survey of the vegetation of Catalonia andAndorra, this paper reports all the phytocoenological associations and subassociations recorded in this area. For each community, we provide the correct name and usual synonyms, its typification (where appropriate), all the references including relevés, and the most outstanding features of its structure, species composition, ecology, distribution and diversity. Moreover, associations and subassociations are ordered appropriately in a syntaxonomic scheme. Syntaxonomic ranks are considered in a fairly broad, conservative sense. This classification established 101 associations, which correspond to the classes Lemnetea, Zosteretea, Potametea, Littorelletea, Montio-Cardaminetea, Phragmiti-Magnocaricetea, Scheuchzerio-Caricetea, Isoeto-Nanojuncetea and Molinio-Arrhenatheretea.

Hygronitrophilous plant communities of Pyrenaean Catalonia and its vicinities. The following communities have been recognized: Alliance Bidention tripartitae: Xanthio italici-Polygonetumpersicarine O. Bolòs 1957, Bidentetum tripartitae W. Koch 1926 (= Polygono hydropiperis-Bidentetum tripartitae Lohm. in Tx. 1950) and Myosoto aquaticae-Bidentetum frondosae, ass. nova. Alliance Convolvulion sepium: Arundini-Convolvuletum sepium (Tx. and Oberd.) O. Bolòs 1962, Oenothero glaziovianae-Asteretum pilosi O. Bolòs and R. Masalles 1983 and Oenothero biennis-Helianthetum tuberosi,ass. nova.

Se aportan datos referentes a dos comunidades de la alianza Primulion intricatae en que participa el subarbusto Salix pyrenaica: Dryado-Salicetum pyrenaicae Chouard ex Vanden Berghen 1970 y Carici-Geetum pyrenaici Chouard ex Vanden Berghen 1970. Ambas se conocían de áreas más atlánticas de la cordillera pirenaica, y principalmente dentro de territorio francés, si bien se disponía de muy pocos inventarios fitosociológicos concretos. En el valle de Aran, aparecen localmente en los afloramientos calizos, y contienen diversos táxones poco comunes o raros en los Pirineos, como por ejemplo Arctostaphylos alpina. Además, ambas comunidades muestran un carácter relativamente particular en comparación con las afines descritas previamente. Por ello, se propone considerarlas como sendas nuevas subasociaciones: Dryado- Salicetum pyrenaicae salicetosum reticulatae, subass. nov., y Carici-Geetum pyrenaici anthyllidetosum boscii, subass. nov.

Como contribución al conocimiento de la flora supraforestal pirenaica y a la política de protección medioambiental, presentamos una relación de los táxones cormofíticos raros o amenazados, existentes en el piso alpino de los Pirineos dentro de los territorios que dependen administrativamente de la Generalitat de Cataluña, Andorra y el departamento de los Pyrénées- Orientales. Dichos táxones se agrupan en seis subapartados, según su área de distribución y su grado de rareza en el territorio considerado. Las plantas especialmente raras o vulnerables se señalan mediante un asterisco situado a continuación del nombre científico. Para la mayoría de los táxones aportamos datos más concretos referentes a distribución y frecuencia.

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.
