ORIGINAL PAPER Orchard and riparian habitats enhance ground dwelling beetle diversity in Mediterranean agro-forestry systems Pedro Martins da Silva Carlos A. S. Aguiar Israel de Faria e Silva Artur R. M. Serrano Rece ived: 18 Marc h 2010 / Accep ted: 30 December 2010 / Publi shed onli ne: 12 Januar y 2011 Ó Springer Science+Business Media B.V. 2011 Abstract The relative contribution of mixed orchard and riparian vegetation patches to local and regional diversity of Mediterranean landscapes dominated by cork-oak wood- lands was tes ted in 2006–2007 using ground, rove and darkling beetl es (Col eopt er a: Car abi dae, Sta phy linida e, Tenebr ionida e). Mixed orch ard and ripa rian gall ery habitat s recorded hi gher values of abundance and species richness for overall beetl e speci es, although most darkling beetle species were associated with the sclerophyllous cork-oak woodlands. Ground and rove beetle community structure changed from the orchard and riparian habitats to samples placed 100 m away into the surrounding cork-oak woodland, i.e., non-cork-oak patches enhanced beta diversity within the landscape mosaic. Analysis of ground beetle traits concerning moisture preferences revealed a higher proportion of hyg rophil ous spe cies in mixed orc hard and riparia n gal lery hab itat s whi le xero phi lou s species were dominant within the cork-oak woodlands. The results of this study suggested that land-use management promoting the maintenance of habitat heterogeneity enhances biodiversity conservation of important hygrophilous and xerophilous species, and subse- quently the sustainable use of Mediterranean agro-forest mosaics.
