Abstract

Structure and function of the Serio River (northern Italy) ecosystem have been evaluated analyzing macroinvertebrate community functional traits. Starting from traits such as Functional Feeding Groups (FFG), Functional Habit Groups (FHG), voltinism and drift behavior, we determined values that can integrate direct measurements of ecosystem attributes and can be used in restoration planning. We collected invertebrates and environmental data in eight sites representative of the longitudinal succession of Serio River environments. High values for most of the ecosystem attributes, indicating good functionality, were confined in three sites of the upstream alpine sector, while downstream the ecosystem was severely impaired and colonized by non-specialized, pioneer communities. The intrinsic information given by ecosystem attributes helped aid the understanding of the health of specific ecosystem functions, thus leading to evaluation of priorities in restoration efforts. This methodology can be a complementary tool in river quality assessment if macroinvertebrate quantitative data are available. Particularly, it can be used in accordance with the new quantitative sampling protocols being adopted in the European Union, and it can define new metrics in a multimetric evaluation system. © 2010 Unione Zoologica Italiana.
