Springs are important environments between hypogean and epigean habitats; the interaction between aquatic and terrestrial ecosystems is an important factor for their biotic communities. We investigated the ecology of the macrobenthic community of two lowland springs in the River Ticino valley, focusing on the autoecology of some relevant species and on the role of springs as hotspots of biodiversity in an area threatened by anthropogenic pressure. We collected 26 taxa in total: diptera (8), trichoptera (6), gastropods (5), coleoptera (2), crustacea (2), lumbricidae (1), odonata (1), plathelminthes (1). Some of them are stenothermal and oligotrophic species thus quite unusual for a flood plain area characterized by intensive agricultural activities. In conclusion, our study highlights the importance of lowland springs in conserving some habitat-selective macrobenthic species.

Several specimens of anomuran and brachyuran decapods are reported from the late Pliocene clays (Argille Azzurre Fm.) at localities nearby Faenza (Ravenna, Emilia-Romagna), located in the foothills of Romagna Apennines (NE Italy). The specimens were assigned to species already reported from the Pliocene of Italy, but never previously recorded in this area. This new report enlarges our knowledge on the composition and distribution of the brachyuran decapods along the Pliocene coastline of the Adriatic Gulf of the paleo- Mediterranean Sea.

Darwin interpreted most of biogeographic distributions as a consequence of dispersal events. The dispersionist approach lasted till the half of the XX century, but then an alternative paradigm arose: vicariantist biogeography. Madagascan carnivores and lemurs, e.g., were considered as heirs of old Gondwanian ancestors. But new phylogeographic research, based on molecular biology, discovered that they evolved, in different times, after the parting of Madagascar from continental Africa, supporting the dispersionist approach. Nowadays, the two paradigms are welcome in all the different cases, thus avoiding the old disputes typical of the last century.
