The Stagnone of Marsala lagoon
2009
The Stagnone of Marsala is an oligotrophic lagoon situated on the western coast of Sicily. The area has been under study since the mid-nineteenth century.

Its main biotic component, a meadow of Posidonia oceanica, is distributed among peculiar reef formations inside and outside the lagoon, which are extremely interesting from an ecological and environmental point of view. The seagrass grows near to its thermal and salinity tolerance level in the inner lagoon, where it is partially replaced by Cymodocea nodosa and Caulerpa prolifera meadows. Algal assembla…
Indagine comparativa sulla popolazione nidificante di Fratino Charadrius alexandrinus (Aves, Charadriiformes) nelle saline della Provincia di Trapani
2016
Comparative survey on the population of the Kentish plover Charadrius alexandrinus in the salt pans of Trapani province. This paper deals with a 2016 census of the breeding population of the Kentish plover in the saltpans of trapani and of the Stagnone di marsala. In the same area a previous census of this species was carried out forty years ago by Massa (1977). the comparison between data collected in the 1970s and in 2016 reveals that the population of the Kentish plover has been dramatically declining, with 70% decrease in the overall area (ca. 1,230 ha). Although responsibile for an additional 8% reduction of wetlands in the last few decades, direct human intervention is not likely to b…
