Oceanic island archipelagos are profoundly interesting ecosystems in which to ask questions about evolutionary patterns and processes, and may rightly be considered as one of the best places on earth to seek an understanding of the origin and elaboration of biological diversity. This 1998 volume brings together contributions covering a range of important issues in contemporary oceanic island plant biology, focusing on patterns and processes in Pacific and other islands (with emphasis on the Bonin, Hawaiian and Juan Fernandez Islands) to provide a stimulating view of the state of research and a possible agenda for future investigations. Topics addressed include chromosomal variation, macromolecular divergence, island biogeography theory, isolating mechanisms, modes of speciation and evolution of secondary plant products, resulting in a volume which reveals the special opportunities offered by oceanic archipelagos for investigating evolutionary phenomena in vascular plants.
Plants are autotrophs and sessile, while animals are heterotrophs and motile. Sessility has imposed on plants 94% hermaphroditism, 23% selfing, 3% polyploidization and 39% clonality, in comparison to...
The polyphyletic Protozoa have explored the possibility of performing almost all metazoan functions with a few subcellular organelles. Their unicellularity and structural simplicity have (i) limited...
This book represents the first attempt to quantify environmental factors and life history traits that accelerate or decelerate species diversity in animals. About 15%, 8% and 77% of species are...
The study of patterns and processes of evolution on islands has played an important role in the development of general theories of how and why evolution occurs. Small, discrete pieces of the...
