Se ha realizado un inventario de los hornos de cal en la Finca Buixcarró, término municipal de Bocairente (Valencia), situada en el Parque Natural de la Sierra de Mariola. Para localizar los hornos, se ha contado con la colaboración del responsable técnico y también se fotointerpretarán mediante la aplicación Google Earth, con tal de encontrar los hornos. Para ello se elaborará una capa de puntos con formato *.kml, posteriormente introduciremos en al GPS, mediante el software (MapSource). Se muestreó la finca en búsqueda de hornos y se georreferenció cada uno de ellos mediante la utilización de un dispositivo GPS, generando un waypoint con su X-Y correspondiente. Una vez georreferenciados los hornos de la finca con formato *.gpx, se elaboró la cartografía correspondiente. Se utilizará GPSBabel y QuantumGis para elaborar la cartografía de los hornos de cal. Se han registrado un total de 24 hornos de cal, de los cuales el 60% presentan un estado de degradación bastante elevado. Se han identificado 20 categorías de usos del suelo, siendo el bosque mixto (Pinus halepensis – Quercus ilex) y el pinar carrasco (Pinus halepensis) las coberturas que mayor superficie ocupan. El inventariado de estas infraestructuras contribuye a la conservación del patrimonio material y cultural de este espacio natural protegido.

The knowledge of the distributional patterns of saproxylic beetles is essential for conservation biology due to the relevance of this fauna in the maintenance of ecological processes and the endangerment of species. The complex community of saproxylic beetles is shaped by different assemblages that are composed of species linked by the microhabitats they use. We evaluate how different the species distribution patterns that are obtained can be, depending on the analyzed assemblage and to what extent these can affect conservation decisions. Beetles were sampled using hollow emergence and window traps in three protected areas of the Iberian Peninsula. Species richness, composition, and diversity turnover were analyzed for each sampling method and showed high variation depending on the analyzed assemblage. Beta diversity was clearly higher among forests for the assemblage captured using window traps. This method collects flying insects from different tree microhabitats and its captures are influenced by the forest structuring. Within forests, the assemblages captured by hollow emergence traps, which collect the fauna linked to tree hollows, showed the largest turnover of species, as they are influenced by the characteristics of each cavity. Moreover, the selection of the forest showing the highest species richness strongly depended on the studied assemblage. This study demonstrates that differences in the studied assemblages (group of species co-occurring in the same habitat) can also lead to significant differences in the identified patterns of species distribution and diversity turnover. This fact will be necessary to take into consideration when making decisions about conservation and management.
