M. da  aCork-oak woodlands as key-habitats for biodiversity conservation in Mediterranean landscapesba case study using rove-beetles (Coleoptera: Staphylinidae).  c2008  aLand-use intensification had become a pressure over woodland sensitive species of Mediterranean agro-forest systems. The effects of a land-use gradient, from old-growth corkoak forest to an agricultural area, were assessed using rove-beetles as indicators. The aim was to find which species were negatively affected by agriculture intensification and benefited from cork-oak patches occurring along the land-use gradient. A total of 3196 rove-beetles from 88 taxa were sampled from all land-use units. Agriculture recorded significantly higher numbers of abundance and species richness in relation to the agro-forest mosaic landscapes. Moreover, 70% of rove-beetle indicator species common enough to be tested by IndVal displayed their highest indicator value for agriculture, showing a lower number of woodland indicators in comparison with ground-beetles. Nevertheless, one rove-beetle taxa was considered as specialist for closed woodland mosaic while no specialist ground-beetle was found for that landscape typology. Some rare and endemic rove-beetle species were also important for typifying diversity patterns of old-growth cork-oak forests. Therefore future conservation work in Mediterranean landscapes should take into account not only indicator species common enough to be tested by IndVal but also rare and endemic species occurring in areas of high conservation importance. Considering the added value of cork-oak woodland cover for sensitive rove- and ground-beetle diversity protection the strengthening of cork-oak woodland connectivity seems crucial in agricultural Mediterranean landscapes.1 aAGUIAR, C.
