Canvis ambientals i modelació antròpica del territori entre l'època ibèrica i l'alt medieval a Catalunya: aportacions de la palinologia

[spa] En los últimos años ha aumentado el interés arqueológico por los cambios territoriales de época histórica. Asimismo, el número de registros polínicos ha aumentado sensiblemente. A pesar de que la falta de marcos cronológicos fiables impone límites a las interpretaciones sobre antropización, el presente artículo pretende realizar una síntesis de los cambios paleoambientales documentados entre los siglos VIII aC y XII dC, haciendo especial referencia a las transformaciones humanas del entorno. Este conjunto de datos polínicos hace evidente una intervención humana al inicio del periodo ibérico, presión que se intensifica durante el iberismo Pleno con la expansión de actividades agrícolas. El mundo romano significa una explotación del espacio menos extensiva, si bien el el siglo VII dC se produce una extensión de los pastos tanto en sectores elevados del Pirineo como de litoral catalán que modifica profundamente el paisaje. [eng] The archaeological interest on the environmental changes during historical times has increased during the last decades. In accordance, a number of palynological from NE Spain records has been recently published. Despite chronological frame works are not yet enough reliable, this paper proposes a synthesis of landscape changes from VIIIth century BC to XIIth century AD. Palynological data suggest the presence of human impacts at ghe beginning of iberic times. Humans pressure, mainly farmning activities, intensified during iberian times. Roman times record a less extensive land use but at the IVth century AD, grazing expanded at regional scale. Pastures expanded again at VIIth century AD, reaching high altitudes in the Pyrenees while at littoral plains, meadows were used for grazing. This period resulted in a deep change of the Catalan lansacapes.

Caracterització i propostes de gestió i conservació dels estanyets de Pals i les closes fondes (Pals, Baix Empordà)

En aquest article es presenten els resultats de l ’estudi dut a terme a tres ullals localitzats a la plana del Baix Ter, al municipi de Pals, coneguts com els estanyets de Pals. S'ha analitzat la fisicoquímica de les aigües de cadascun dels estanyets, s'ha inventariat la vegetació i s ’ha estudiat la població íctica i la presència d'amfibis. Malgrat que es tracta d'un espai reduït, els estanyets de Pals i el sector de les Closes Fondes actuen com a veritables zones humides, amb vegetació i fauna pròpies d'aquests amenaçats indrets. Les anàlisis de les aigües han revelat una situació tròfica classificada a mig camí entre la mesotròfia i l'eutròfia. Segons aquests resultats s'han elaborat unes propostes de gestió i conservació per a aquest indret que inclouen la seva preservació mitjançant acords de custòdia, la creació de zones tampó, la gestió de la vegetació i l ’aplicació de programes de seguiment de la qualitat de les aigües

Landscape Systems and Human Land-Use Interactions in Mediterranean Highlands and Littoral Plains during the Late Holocene: Integrated Analysis from the InterAmbAr Project (North-Eastern Catalonia).

The main goal of the InterAmbAr reseach project is to analyze the relationships between landscape systems and human land-use strategies on mountains and littoral plains from a long-term perspective. The study adopts a high resolution analysis of small-scale study areas located in the Mediterranean region of north-eastern Catalonia. The study areas are distributed along an altitudinal transect from the high mountain (above 2000m a.s.l.) to the littoral plain of Empordà (Fig. 1). High resolution interdisciplinary research has been carried out from 2010, based on the integration of palaeoenvironmental and archaeological data. The micro-scale approach is used to understand human-environmental relationships. It allows better understanding of the local-regional nature of environmental changes and the synergies between catchment-based systems, hydro-sedimentary regimes, human mobility, land-uses, human environments, demography, etc.

Crustacean and aquatic insect assemblages in the Mediterranean coastal ecosystems of Empord`a wetlands (NE Iberian peninsula)

Coastal wetlands are characterized by high biodiversity, which is one of the main criteria considered when establishing protection policies or when proposing adequate management actions. In this study, the crustacean and aquatic insect composition of the Empord`a wetlands is described. These two faunal groups contribute highly to the total biodiversity in these wetlands but are seldom considered when managing natural areas. A selection (84 sampling points) of all water body types present in the Empord`a wetlands were sampled monthly (surber and dip net with a 250 μm mesh). Sampling was carried out during 3 surveys (1991-92, 1996-97 and 1999-2000). A rich fauna of 125 crustacean and 295 aquatic insect taxa was identified. We characterized each water body type using the most abundant species and the relative species richness of the taxonomic groups. A classification of the water body types, according to similarity between inventories, groups the brackish and hyperhaline systems in one cluster and the various freshwater systems in another one. Among freshwater systems, lotic waters and freshwater wetlands have a high similarity, whereas rice fields and freshwater springs have a low similarity

Organic carbon and nutrient (P, N) concentrations of water and sediment in several aquatic environment types of a Mediterranean coastal wetland (Empordà Wetlands, NE Iberian Peninsula)

Total sediment and water organic carbon and nutrient (nitrogen and phosphorus) concentrations of different environment types of a Mediterranean coastal wetland (temporary and brackish, temporary and freshwater, semi-permanent and brackish, and permanent and brackish basins) were analysed during two hydroperiods. A nitrogen limitation was found for both sediment and water. The total organic carbon concentration of the water was significantly related to the water level, which varies throughout the hydroperiods. In contrast, the total organic carbon concentration of the sediment was not related to water level. However, significant differences in total organic carbon of the sediment were found between hydroperiods. On the other hand, total organic carbon of the sediment varied spatially, being higher in temporary brackish basins with lower sand content, and lower in permanent and semi-permanent brackish basins with higher sand content

Technological trampolines for new venture creation in Catalonia: the case of the University of Girona

Recent trends in technology transfer show an intensification of spin-off creation as a modality of university research commercialisation, complementary to the conventional ones, contract research and licensing. In this paper we analyse the evolution, objectives, resources and activities of a specialised unit –Technological Trampoline (TT) - in charge of new venture creation at the University of Girona (Catalonia-Spain). Based on two theoretical frameworks, Resource-based-view and Institutional Theory, we adopt a multi-dimensional approach to study the strategy of spinning-off new ventures at the University of Girona in terms of resources and activities, how this process is organised and if the outputs fit with this UdG’s objectives and the local environment. Our main contribution is an in-depth analysis of the spin-off creation unit with special emphasis on its variety of resources and activities. The results have a series of implications and recommendations at both university and TT level.

Milk, from medicine to food Mediterranean Europe: Catalonia, 19th-20th centuries

The spread of milk consumption was a significant change in the diet of Europeans, however it is one that has not been greatly studied with regard to the populations of Mediterranean Europe. In this article we shall analyse the ain circumstances that conditioned that process in Catalonia between the middle of the 19th century and 1936. In our study we shall argue that the consumption of milk in this area was only relevant in the 19th century in situations of illness or old age, and that it subsequently increased and acquired a new significance as a result of various factors. In particular, we shall emphasise: (a) the scientific advances in microbiology and nutrition, (b) the activities carried out by doctors and various public institutions to promote the consumption of fresh milk, and (c) the technological innovations in the milk producing sector. In Appendix 1 we show two maps representing the main territorial references that we shall mention.
