La photographie a la faculté de révéler à tous des lieux inédits, difficiles d'accès, et de montrer les paysages rares et fragiles qu'ils recèlent. Ce recueil de photographies du milieu souterrain du Geopark mondial Unesco Famenne - Ardenne a été réalisé dans ce but. Les grottes et carrières souterraines sont par définition cachées et souvent inconnues du regard de tout un chacun. Ce patrimoine souterrain si riche et si beau, seuls les spéléologues ont le privilège de l'explorer, l'étudier, le protéger, mais aussi… de le photographier. À ce jour, selon les Atlas du karst wallon publiés par la CWEPSS (Commission Wallonne d’Étude et de Protection des Sites Souterrains), on ne dénombre pas moins de 1.000 sites karstiques (grottes, dolines, résurgences…) au sein du Geopark Famenne - Ardenne. La grande connaissance de ces sites par l’Union Belge de Spéléologie (UBS) permet une gestion des cavités dans un souci de protection et d’éducation.

What was the relationship between the Alps and the Resistance during the Italian Social Republic? This book explores the function of the Alps as a center of battles, violence, and opposition to fascism, as well as the cradle of political debate destined to forge modern Italian and European democracy.

"Many animals, from birds to insects, build structures using wood, soil, or a range other materials. Suprisingly to most people, a similarly diverse array of animal homes exist underground, in the hiddent world beneath our feet. This is particularly true for ants who excavate large and complex nests in which they shelter, reproduce and generally go about their lives. Despite the existence of this vast underground world, it has remained largely unexplored. Walter Tschinkel, however, has spent his career researching underground ant nests in his home state of Florida (where they are particularly prevalent) and this book is his story of discovery about what he has learned about these nests and they reveal about ant biology and behavior more broadly. Tschinkelstarts the book by describing just how he studies ants nest - an arduous excavation process which involves first filling the nests with plaster, molten metal or wax. But this is a book driven by fascinating questions and the experiments the author has devised to try and answer them. How does nest architecture vary across ant species? How are new nests excavated during colony relocation? Are the ants organized within the nest? Do ants have "architectural plans?" What is the effect of all this nest excavation on soils? And how does the division of labor within the nest work? Ultimately, Tschinkel provides answers to many of these questions, but also acknowledges what mysteries, including why nests evolved in the first place, still remain. In telling this story, Tschinkel introduces readers to the surprising beauty and architectural complexity of underground ant nests and to how scientific research on them is done."--
