The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year.

This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.

This volume gathers case studies on plant diversity from selected, representative mountain systems of Italy (Mediterranean and temperate zones), while also addressing the biodiversity of avian fauna. For the Alps, Wilhalm and Prosser examine the species biodiversity (also with the help of highly detailed location maps) of the sector of the central Alps that corresponds to the basin of the Adige, including some nearby valleys, between the watershed to the north and the Prealps to the south (Alto Adige and Trentino). In turn, Pedrotti investigates the vegetation series of the same territory in relation to the three climatic sectors identified: prealpine, alpine and endoalpine. Aleffi then explores the relationships between the distribution of a number of species of bryophytes and the main mesoclimatic gradients along a transect through the Valle dell’ Adige between 46°40''N and 45°42''N. Lastly, Siniscalco studies the ways in which alien species are now invading the western Alps, whichto date have remained largely unaffected by this phenomenon, unlike the plains and hills.

For the Apennines, Ferrari studies the tree line and the biodiversity of the vegetation of the northern Apennines; for the mountains of Sicily, Bazan conducts a diachronic analysis of the beech forests of the Monti Nebrodi.

The contribution by Venanzoni interprets the chorology of associations of the Magnocaricetalia order throughout Italy, relating it to the climatic and geographic gradients. He describes a total of 55 associations, reporting on the distribution in the temperate zone (differentiating between the alpine and continental) and the Mediterranean zone for each of them.

Cianfaglione presents the Signal Project Italian site. This project investigates the effects of extreme weather events on secondary grassland and the role of selected alien species, mowing, biodiversity, productivity and functional traits, in Italy and along a European gradient.

Forthe Marches Region, Forconi describes the biodiversity of the avian fauna in relation to the altitudinal gradient and the potential vegetation.
