Molecular data from three chloroplast markers resolve individuals attributable to Radula buccinifera in six lineages belonging to two subgenera, indicating the species is polyphyletic as currently circumscribed. All lineages are morphologically diagnosable, but one pair exhibits such morphological overlap that they can be considered cryptic. Molecular and morphological data justify the reinstatement of a broadly circumscribed ecologically variable R. strangulata, of R. mittenii, and the description of five new species.
The Göttingen conference Systematics 2008 is the first joint meeting of the Gesellschaft für Biologische Systematik (GfBp. and the German Botanical Society, section Biodiversity and Evolutionary Biology (DBG), being the 10th Annual Meeting of the GfBS and the 18th International Symposium Biodiversity and Evolutionary Biology of the DBG. The conference programme covers biological systematics in the widest sense and provides ample opportunities for oral and poster presentations on new advances in plant, animal and microbial systematics. This volume brings together the abstracts of invited speaches from the plenary sessions on Progress in Deep Phylogeny, Speciation and Phylogeography, and New Trends in Biological Systematics as well as those of submitted talks and poster sessions.
This third and voluminous (Set of volumes I-III available at nice price) final volume of Schuster's Austral Hepaticae treats two large families: Geocalyaceae (including Lophocoleoideae), Plagiochilaceae, and several smaller families including Acrobolbaceae and Balantiopsidaceae. This volume completes the comprehensive and significant evolutionary-systematic research program completed by Professor Schuster which began in the mid-1950s and revolutionised our understanding of both relationships and diversity in liverworts. His legacy is a classification that remains recognisable as largely his, particularly at deeper phylogenetic levels. Professor Schuster had strong views on character evolutio...
Questions why species are becoming extinct, and how we can protect the natural world on which we all depend.
