Plant geographical description of the area, syntaxonomy, spatial patterns, floristic richness, structure of plant communities in relation to soil properties and herbivore influence were described for a mountain region that is difficult to access. Seasonal, inter-annual, and long-term dynamics of vegetation are discussed on the base of long-term observations as well as pollen and phytolith analyses. Population biology of alpine plants is studied by combination of field observations and mathematical modelling. Plant population strategies and soil seed banks are described for alpine plants from several communities. Results of long-term ecological experiments (plant reciprocal transplantations, dominant removals, light limitation) showed the significance of competition and facilitation for community organization. Structure of soil algal and fungal communities is represented as well as mycorrhiza of alpine plants. Main animal groups (wild) history and modern nature conservation problems are discussed.

This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.
