Evolution and speciation of island plants : [papers resulted from a symposium convened by the co-editors at the XV International Botanical Congress in Yokohama, Japan, August, 1993

Oceanic island archipelagos provide many clues about evolutionary patterns and processes, and may rightly be considered as among the best places on earth to seek an understanding of the origin and elaboration of biological diversity. This volume brings together contributions covering a range of important issues in contemporary oceanic island plant biology, focusing on patterns and processes in various island groups (with emphasis on the Bonin, Hawaiian and Juan Fernandez Islands) to provide a stimulating view of the current 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. The result is a volume that reveals the special opportunities offered by oceanic archipelagos for investigating evolutionary phenomena in vascular plants.

Hawaiian Islands -- Pt. 2. Juan Fernandez Islands -- Pt. 3. Southern And Western Pacific Islands -- Pt. 4. General Evolutionary Patterns And Processes On Oceanic Islands. Edited By Tod F. Stuessy And Mikio Ono. Papers Resulted From A Symposium Convened By The Co-editors At The Xv International Botanical Congress In Yokohama, Japan, August, 1993--pref. Includes Bibliographical References And Indexes. Chromosome numbers available for about 38% of the 956 native species of Hawaiian plants indicate that more than 80% are polyploid.
