TL;DR: Recent cladistic analyses are revealing the phylogeny of flowering plants in increasing detail, and there is support for the monophyly of many major groups above the family level.
Journal ArticleDOI
Abrupt tropical climate change: Past and present
Lonnie G. Thompson,Ellen Mosley-Thompson,Henry H. Brecher,Mary E. Davis,Blanca León,Donald H. Les,P.-N. Lin,T. A. Mashiotta,Keith R. Mountain +8 more
TL;DR: It is argued that the present warming and associated glacier retreat are unprecedented in some areas for at least 5,200 yr, which is not only contributing to global sea-level rise but also threatening freshwater supplies in many the world's most populous regions.
Journal ArticleDOI
Phylogenetic Studies in Alismatidae, II: Evolution of Marine Angiosperms (Seagrasses) and Hydrophily
TL;DR: The evolution of hydrophily, unisexuality, and marine habit in angiosperms was explored using estimates of phylogeny obtained by phylogenetic analyses of chloroplast (rbcL) gene sequence data.
Journal ArticleDOI
The central role of dispersal in the maintenance and persistence of seagrass populations

Lowe,Oriol Mascaró i Vidal,Jillian Lean Sim Ooi,Robert J. Orth,David O. Rivers,Leonardo Ruiz-Montoya,Elizabeth A. Sinclair,John Statton,Jent Kornelis van Dijk,Jennifer Verduin +17 more
TL;DR: The role that sexual reproduction, pollen, and seed dispersal play in maintaining species distributions, genetic diversity, and connectivity among seagrass populations is explored and the relationship between long-distance dispersal, genetic connectivity, and the maintenance of genetic diversity is addressed.
Journal ArticleDOI
Molecular phylogenetics of the Magnoliidae: cladistic analyses of nucleotide sequences of the plastid gene rbcL.
TL;DR: Six magnoliids formed five major groups, roughly corresponding to the Magnoliales, Laurales, Aristolochiaceae/Piperales, Nymphaeales, and Ranunculales/Papaverales; Ceratophyllum (CeratophyLLaceae) was found to be sister to all other angiosperms.
