Mosses are a major component of the vegetation in ice-free coastal regions of Antarctica. They play an important role in the colonisation of ice-free terrain, accumulation of organic matter, release of organic exudates, and also provide a food and habitat resource for invertebrates. They serve as model organisms for physiological experiments designed to elucidate problems of plant cold tolerance and survival mechanisms and for monitoring biological responses to climate change. This Flora provides the first comprehensive description, with keys, of all known species and varieties of moss in the Antarctic biome. It has involved microscopic examination of around 10,000 specimens from Antarctica and, for comparison, from other continents. All species are illustrated by detailed line drawings, alongside information about their reproductive status, ecology, and distribution. This is an invaluable resource for bryologists worldwide, as well as to Antarctic botanists and other terrestrial biologists.

Seed dispersal by ants (myrmecochory) still provides numerous interesting questions concerning dispersal patterns and mutualistic benefits to both ants and plants. The contribution of a rather small-sized but highly abundant ant species of Central Europe, Temnothorax crassispinus, to myrmecochory is studied in particular and the benefit of the plants derived from their dispersal activity is assessed. The findings are discussed and illustrated and an outlook is presented about future research perspectives. Furthermore, a meta-analysis of the specificity of seed dispersal by ants is undertaken. Despite the lack of species-specific relations in myrmecochory, where it is shown that especially seeds with very low seed mass and those with very high seed mass are dependent on both small and large ants, respectively, for their dispersal.

Today we associate the Renaissance with painting, sculpture, and architecture—the “major” arts. Yet contemporaries often held the “minor” arts—gem-studded goldwork, richly embellished armor, splendid tapestries and embroideries, music, and ephemeral multi-media spectacles—in much higher esteem. Isabella d’Este, Marchesa of Mantua, was typical of the Italian nobility: she bequeathed to her children precious stone vases mounted in gold, engraved gems, ivories, and antique bronzes and marbles; her favorite ladies-in-waiting, by contrast, received mere paintings. Renaissance patrons and observers extolled finely wrought luxury artifacts for their exquisite craftsmanship and the symbolic capital of their components; paintings and sculptures in modest materials, although discussed by some literati, were of lesser consequence. This book endeavors to return to the mainstream material long marginalized as a result of historical and ideological biases of the intervening centuries. The author analyzes how luxury arts went from being lofty markers of ascendancy and discernment in the Renaissance to being dismissed as “decorative” or “minor” arts—extravagant trinkets of the rich unworthy of the status of Art. Then, by re-examining the objects themselves and their uses in their day, she shows how sumptuous creations constructed the world and taste of Renaissance women and men.

This textbook on biofilms combines knowledge on sub-aquatic and sub-aerial biofilms and their products (stromatolites, oolites, ore, petroleum and gas deposits). It describes how formation and degradation of minerals and rocks is achieved through biofilm formation on and in sediments, soils and rocks. Methods of study, examples of Precambrian biofilms of an early Earth as well as the most recent examples of desert rock biofilms are treated in this integrative book on biofilms, microbial mats and stromatolites.
