Journal Article

Kåre Bremer,Mark W. Chase,Peter F. Stevens,Arne A. Anderberg,Anders Backlund,Birgitta Bremer,Barbara G. Briggs,Peter K. Endress,Michael F. Fay,Peter Goldblatt,Mat H. G. Gustafsson,Sara B. Hoot,Walter S. Judd,Mari Källersjö,Elizabeth A. Kellogg,Kathleen A. Kron,Donald H. Les,Cynthia M. Morton,Daniel L. Nickrent,Richard G. Olmstead,RA PRice,Christopher J. Quinn,JE Rodman +22 more
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
Low host specificity of herbivorous insects in a tropical forest
Vojtech Novotny,Yves Basset,Scott E. Miller,George D. Weiblen,Birgitta Bremer,Lukas Cizek,Pavel Drozd +6 more
TL;DR: It is shown that most herbivorous species feed on several closely related plant species, suggesting that species-rich genera are dominant in tropical floras, and monophagous herbivores are probably rare in tropical forests.
Journal ArticleDOI
Phylogenetics of asterids based on 3 coding and 3 non-coding chloroplast DNA markers and the utility of non-coding DNA at higher taxonomic levels
Birgitta Bremer,Kåre Bremer,Nahid Heidari,Per Erixon,Richard G. Olmstead,Arne A. Anderberg,Mari Källersjö,Edit Barkhordarian +7 more
TL;DR: The analysis has contributed to reclassification of several families, e.g., Tetrameristaceae, Ebenaceae, Styracaceae, Montiniaceae, Orobanchaceae, and Scrophulariaceae (by inclusion of Pellicieraceae, Lissocarpaceae, Halesiaceae, Kaliphoraceae, Cyclocheilaceae, respectively), and to the placement of families that were unplaced in the APG-system.
Journal ArticleDOI
A parsimony analysis of the Asteridae sensu lato based on rbcL sequences.
TL;DR: A parsimony analysis of 156 representative sequences of the Asteridae sensu lato and 28 outgroup sequences was conducted using a two-tiered approach, designed to discover multiple islands of equal parsimony using the heuristic search routine in PAUP.
Journal ArticleDOI
Molecular Phylogenetic Dating of Asterid Flowering Plants Shows Early Cretaceous Diversification
TL;DR: It is shown that asterids and their major subgroups euasterids, campanulids, and lamiids diversified during the Early Cretaceous, and an origin and first phase of diversification in the EarlyCretaceous is supported.
