El mantenimiento de los bienes culturales como garantía para su conservación

La conservación del Patrimonio se debe basar fundamentalmente en la preservación. Cuando se trata de obras expuestas a la intemperie no resulta viable implantar medidas preventivas que permitan controlar las condiciones ambientales que influyen de manera determinante en el desarrollo de los procesos de deterioro. En estos casos, la conservación preventiva se debe centrar en mantener en buen estado los materiales de construcción y los elementos arquitectónicos, tanto estructurales como funcionales o de protección y en la aplicación de programas de mantenimiento. Este tipo de actuaciones permiten la detección precoz de los daños evitando un agravamiento de la patología y son, además, un mecanismo que rentabiliza las inversiones económicas que las instituciones encargadas de la tutela de los bienes culturales dedican a su restauración. Por otra parte, las labores de control y mantenimiento permiten evaluar la idoneidad de los tratamientos y de las soluciones adoptadas.The Conservation of Cultural Heritage must be based mainly upon preservation. When it comes to in situ outdoor works, it is not possible to apply preventive measures to control the environmental conditions that influence the deterioration process. In these cases, preventive conservation must be focused on maintaining both the structural and functional construction materials and the architectonical elements in a good state, or in protection and also implementation of maintenance programs. These kinds of actions will allow the early detection of damage, avoiding the worsening of the pathology. They will also make profitable the economic investment made for the restorations works by institutions responsible for the protection of cultural heritage. On the other hand, control and maintenance actions allow the assessment of the suitability of the adopted treatments and solutionsA conservação do Património deve-se basar fundamentalmente na preservação.

Aquatic macrophytes in Doñana protected area (SW Spain) : an overview

A big portion of the Doñana protected areas corresponds to wetlands; in them aquatic macrophytes are the main primary producers and play also other important ecological functions. Nevertheless, they are inconspicuous organisms and their importance in these ecosystems does not seem to be well reflected in the bibliography about this natural area. This paper reviews the most significant information gathered about this group of organisms in this protected area, provides an updated catalogue of this group of plants, and offers some considerations related with this topic.Una gran parte de los espacios protegidos de Doñana corresponde a humedales, en ellos los macrófitos acuáticos son los principales productores primarios, realizando además otras importantes funciones ecológicas. Sin embargo, son organismos poco conspicuos y su importancia en estos ecosistemas no parece estar reflejada en las publicaciones existentes relativas a este espacio natural. Este artículo recopila la información más significativa sobre este grupo de organismos en este espacio protegido, proporciona el catálogo actualizado de este grupo de vegetales y ofrece algunas consideraciones relativas al tema

Salt lakes of La Mancha (Central Spain): A hot spot for tiger beetle (Carabidae, Cicindelinae) species diversity

The tiger beetle assemblage of the wetlands of La Mancha (central Spain) comprises nine species: Calomera littoralis littoralis, Cephalota maura maura, Cephalota circumdata imperialis, Cephalota dulcinea, Cicindela campestris campestris, Cicindela maroccana, Cylindera paludosa, Lophyra flexuosa flexuosa, and Myriochila melancholica melancholica. This assemblage represents the largest concentration of tiger beetles in a single 1º latitude / longitude square in Europe. General patterns of spatial and temporal segregation among species are discussed based on observations of 1462 specimens registered during an observation period of one year, from April to August. The different species of Cicindelini appear to be distributed over space and time, with little overlapping among them. Three sets of species replace each other phenologically as the season goes on. Most of the species occupy drying or dried salt lakes and salt marshes, with sparse vegetation cover. Spatial segregation is marked in terms of substrate and vegetation use. Calomera littoralis and M. melancholica have been observed mainly on wet soils; C. circumdata on dry open saline flats; C. dulcinea and C. paludosa in granulated substrates with typical halophytic vegetation; C. maura is often present in man-modified areas. Cephalota circumdata and C. dulcinea are included as species of special interest in the list of protected species in Castilla–La Mancha. Conservation problems for the Cicindelini assemblage arise from agricultural activities and inadequate use of sport vehicles. Attempts at restoring the original habitat, supressing old semi-industrial structures, may affect the spatial heterogeneity of the lakes, and have an effect on Cicindelinae diversity.This study was possible thanks to the support from the Fundación Global Nature through the European Life European Community Project Humedales de La Mancha (LIFE10 NAT/ES/000563), Spanish Ministry of Agriculture, Food and Environment and to the facilities provided by the Museo Nacional de Ciencias Naturales (MNCN-CSIC).Peer reviewe
