Ambos factores están condicionados por la gestión forestal. Para responder a estas dos preguntas se ha muestreado la comunidad de murciélagos en distintas estructuras de hayedo en Cataluña.

También se inspeccionaron un total de 237 cajas refugio para murciélagos instaladas en cada tipología de bosque durante el verano y otoño entre 2006 y 2008. Los resultados anal...

Its general aim is to create, define or apply common strategies for the protection and restoration of SUDOE fluvial corridors. The partnership is leaded by the Technical University of Lisbon (Instituto Superior de Agronomia, PT) and includes a regional water authority (ARH Algarve, PT), a water management enterprise (Águas do Algarve, PT), a regional authority (Junta de Extremadura, ES) and a Regional Developmental Center (Centre Tecnològic Forestal da Catalunya, ES). The mainstream of activities is river restoration, in its various scales and actions, including the identification and causal quantification of river degradation, elaboration of maps for restoration p...

These cavities provide them with a stable environment at critical vital moments such as breeding or hibernation, day or migratory resting areas and an adequate protection from predators (Meier and Garcia, 2000; Parsons et al, 2003). Hydroelectric plants, with underground caves, galleries and water nearby, have appropriate areas to be used by bats, as long as they fulfill the following requirements: darkness, quietness and certain humidity and temperature. This variables combined with other factors like mine's approximate volume, configuration, elevation, and a number and location of connected surface entrances are key determinants as how, when and where bats will use mines (Tuttle and Taylor, 1998). In this research the galleries from several Catalan hydroelectric centrals are subject of study in order to determine its importance as shelters for species of bats and, consequently, its potential to be used as roosts, being the first study of its kind conducted in Catalonia.

Se han obtenido datos de 26 especies que aportan información para 597 nuevas cuadrículas UTM 10x10 km, con relación a las ya existentes. Se muestra información de especies poco conocidas en Catalunya, como son el nóctulo grande (Nyctalus lasiopterus), murciélago ratonero bigotudo pequeño (Myotis alcathoe), murciélago ratonero bigotudo (Myotis mystacinus), murciélago ratonero gris ibérico (Myotis escalerai), murciélago ratonero gris itálico (Myotis sp1), murciélago ratonero forestal (Myotis bechsteinii) y orejudo alpino (Plecotus macrobullaris). A partir de los datos existentes, se elabora una ficha y se propone una categoría de conservación (Lista Roja) según los criterios de la UICN (versión 3.1, 2001) para todas las especies de murciélagos de Catalunya y se incita a promover seguimientos y estudios ecológicos para una correcta gestión y conservación de las especies presentes en dicho territorio.

In the Mediterranean landscape, riparian corridors emerge from surrounding landscapes as “linear oasis” with particular structural and compositional features. They are, however, severely altered by adjacent human activities and land uses in the drainage basins, which pollute, impose barriers, extract or transfer water, straighten and constrain river channels, alter banks or cut vegetation to gain space. There is an urgent need to support actions to protect river systems and to restore their original ecological integrity and functions, as the Water Framework Directive imposes to all member states. Moreover, according to the “European Spatial Development Perspective”, biodiversity cannot be preserved with only a network of protected areas, but also needs the development of ecological corridors. Cooperation among different actors at regional levels arises ...
