This Catalogue lists the hepatics and hornworts from Chile, Argentina and Uruguay, by their legitimate and illegitimate names, provided with information on type specimens, published figures, maps, bibliographic citations and localities. There are also Annotations on non legitimate and erroneous names. The Systematic list on the 748 accepted names of Marchantiophyta and 24 of Anthocerotophyta of the area is complemented with the synonyms and arranged in the most recent classifications. Large areas are still under-investigated as shown in the geographic lists of the taxa present in the countries and their provinces.

This book provides keys, descriptions and illustrations for about 850 species of liverworts and hornworts, in 148 genera and 47 families, of Colombia and Ecuador. The largest genera are Lejeunea (66 spp.), Plagiochila (65), Frullania (54), Radula (33), Metzgeria (33), Cololejeunea (32), Cheilolejeunea (30), Bazzania (26), Drepanolejeunea (25), Ceratolejeunea (18), Diplasiolejeunea (18), and Syzygiella (18). Species descriptions include brief morphological characterization and discussion with emphasis on characters for identification, world range as well as distribution and habitat in Colombia and Ecuador. Classes, orders, families and genera are also described and the main features for recognition of the genera are briefly discussed. The introduction includes chapters on history of exploration, diversity and endemism, and classification. A glossary, bibliography and index to scientific names are also provided.

This book presents twenty peer-reviewed contributions delineating the full breadth of current diatom-related research in the Earth, atmospheric and biological sciences. The volume is dedicated to Dr. Eugene F. Stoermer, who has worked with most of the contributors to this volume, for his life-long scientific work on a variety of topics, the common thread of which has always been diatoms.

In the humid forests of Cape Horn, a single tree can host more than 100 species of little epiphyte plants. The floor of the forest and the rocks are also covered by numerous species of liverworts, mosses, and lichens. The decision to stop at a tree or rock and explore these "miniature forests" generates an authentic ecotourism experience. In a small area we can spend several minutes or hours with a magnifying glass or camera discovering the colors, shapes, and textures of the most diverse organisms of Cape Horn. This guidebook enhances exploration by providing information to understand the architecture, life cycles, and identification of taxonomic groups of the organisms that form them.
