Abstract
ABSTRACT Background There are conflicting views between palaeobotanists and plant systematists/evolutionary biologists regarding the occurrence of plant speciation in the Quaternary. Palaeobotanists advocate that Quaternary speciation was rare despite opposing molecular phylogenetic evidence, the extent of which appears underappreciated. Aims To document, describe and discuss evidence for Quaternary plant speciation across different geographical regions based on dated molecular phylogenies and related studies. Methods From a search of the literature, we compiled a selection mainly of dated molecular phylogenies from all continents (except Antarctica) and from all major climate zones. Results Molecular phylogenetic analyses and related studies show that Quaternary plant speciation and radiations occurred frequently and that in many instances Quaternary climatic oscillations were likely important drivers of them. In all geographical regions studied, Quaternary plant speciation and radiations were particularly evident in mountainous areas and arid regions, and were also prevalent on all major oceanic archipelagos. Conclusions Based on our survey of the molecular phylogenetic and related literature we propose there is now overwhelming evidence that plant speciation and radiations were ubiquitous during the Quaternary. We therefore reject the view of palaeobotanists that plant speciation was rare during this period and briefly discuss possible reasons for this discrepancy.
期刊介绍:
Plant Ecology and Diversity is an international journal for communicating results and novel ideas in plant science, in print and on-line, six times a year. All areas of plant biology relating to ecology, evolution and diversity are of interest, including those which explicitly deal with today''s highly topical themes, such as biodiversity, conservation and global change. We consider submissions that address fundamental questions which are pertinent to contemporary plant science. Articles concerning extreme environments world-wide are particularly welcome.
Plant Ecology and Diversity considers for publication original research articles, short communications, reviews, and scientific correspondence that explore thought-provoking ideas.
To aid redressing ‘publication bias’ the journal is unique in reporting, in the form of short communications, ‘negative results’ and ‘repeat experiments’ that test ecological theories experimentally, in theoretically flawless and methodologically sound papers. Research reviews and method papers, are also encouraged.
Plant Ecology & Diversity publishes high-quality and topical research that demonstrates solid scholarship. As such, the journal does not publish purely descriptive papers. Submissions are required to focus on research topics that are broad in their scope and thus provide new insights and contribute to theory. The original research should address clear hypotheses that test theory or questions and offer new insights on topics of interest to an international readership.
