Biogeographic analysis of the woody plants of the Southern Appalachians: Implications for the origins of a regional flora.
(Am J Bot, 2015-05)PREMISE OF THE STUDY: We investigated the origins of 252 Southern Appalachian woody species representing 158 clades to analyze larger patterns of biogeographic connectivity around the northern hemisphere. We tested biogeographic ... -
Evidence for a Cenozoic radiation of ferns in an angiosperm-dominated canopy.
(Proceedings of the National Academy of Sciences of the United States of America, 2009-07)In today's angiosperm-dominated terrestrial ecosystems, leptosporangiate ferns are truly exceptional--accounting for 80% of the approximately 11,000 nonflowering vascular plant species. Recent studies have shown that this ... -
Ferns diversified in the shadow of angiosperms.
(Nature, 2004-04)The rise of angiosperms during the Cretaceous period is often portrayed as coincident with a dramatic drop in the diversity and abundance of many seed-free vascular plant lineages, including ferns. This has led to the widespread ... -
Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants.
(Nature, 2001-02)Most of the 470-million-year history of plants on land belongs to bryophytes, pteridophytes and gymnosperms, which eventually yielded to the ecological dominance by angiosperms 90 Myr ago. Our knowledge of angiosperm phylogeny, ...
