CHANGES IN COLLEMBOLA RICHNESS AND DIVERSITY ALONG A GRADIENTOF LAND-USE INTENSITY : A pan European study

2006

Changes in Collembola richness and diversity along a land-use intensity gradient were studied in eight European countries (Portugal, Spain, France, Switzerland, Hungary, UK, Ireland and Finland). In each country a set of six 1 km2 land-use units (LUUs) were selected forming a gradient ranging from natural forest to agricultural dominated landscapes, passing through mixed-use ones. In addition to data on Collembola, detailed information regarding landscape diversity and structure was collected for each LUU. A total of 47,774 individuals were identified from 281 species. Collembola reacted not only to changes in the diversity of the landscape, but also to the composition of that diversity and…

LaDy: Software for assessing local landscape diversity profiles of raster land cover maps using geographic windows

2003

Landscape ecology starts from the assumption that diversity and spatial arrangement of ecosystem mosaics have ecological implications and tries to understand the interactions between diversity and structure of large spatially heterogeneous areas and their ecological functions. These assumptions imply effective use of earth observation techniques and geographic information systems, enabling a global view of the landscape mosaics. In this paper, a software, LaDy (Landscape Diversity Software), for computing Re´nyi’s local landscape diversity profile on raster land cover maps is presented. LaDy is based on the use of Merchant’s adaptive geographic window, which is designed to operate on a neig…

Diversità paesaggistica e multifunzionalità dei sistemi agro-forestali dell’Etna

2010

Il paesaggio dell’Etna è un complesso di paesaggi ricchi e diversissimi grazie alla estrema variazione di quote ed esposizioni che da sempre condizionano attività umane e crescita degli organismi; il cono vulcanico etneo rappresenta il principale rilievo e contemporaneamente la formazione geologica più giovane dell’Isola. Tra la fascia basale, maggiormente soggetta ad intesificazioni colturali e quella montana a carattere forestale domina la fascia pedemontana caratterizzata da un’importante valenza paesaggistica e biologica. Allo scopo di prevenire la degradazione o peggio ancora la perdita di questi particolari agroecosistemi è necessario colmare le lacune conoscitive sulla classificazion…
