Arthropods Biodiversity in Agricultural Landscapes: Effects of Land Use and Anthropization

Abstract

The greatest proportion of Po river plain is occupied by arable lands. Negative effects of modern intensive agriculture on biodiversity can derive from various phenomena operating at different spatial scales, from local to regional ones. If agricultural fields are subjected to periodical disturbances by farming practices, also landscape structure can influence community structure in the fields providing refugial areas or alternative trophic resources. In the same way in perennial habitats, such as strips and meadows, community structure and composition may be linked to both local factors and surrounding land use, that can influence organism persistence and dispersal mechanisms. We studied some natural and anthropized habitats in a wide agricultural area in the province of Ferrara (conventional annual and perennial fields, herbaceous strips, hedgerows and meadows) to investigate relationships between arthropod community structure and both local impact factors (habitat type, management) and surronding landscape structure and use. Results from uni and multivariate analysis showed a great influence on trophic and taxonomic structure of habitat type and quality.A less complex landscape had only slightly influence on trophic structure, leading to higher abundance and richness of generalist taxa. In conclusion we emphasize the importance of maintaining high-quality habitats to enhance arthopod diversity in agricultural landscapes.
