Morphology and placental mammal phylogeny.
In a recent article on placental mammal phylogeny (Springer et al., 2007), we discussed evidence for correlated character evolution among morphological characters. We also performed pseudoextinction analyses that assessed whether placental orders remained in the expected superordinal group (Afrotheria, Xenarthra, Euarchontoglires, Laurasiatheria) when molecular and soft-tissue data were coded a...
متن کاملDNA and Morphology: Plant Phylogeny
helpful in identifying critical factors for population management. Tony Starfield (University of Minneapolis) described another population simulation model and showed how a different approach to modelling is required when many parameters and their ranges are unknown. Unlike engineering applications, models should not be used to seek optimal solutions, but instead to identify and minimize risks....
متن کاملFloral Morphology and Phylogeny in the Hydrocharitaceae
The vascular anatomy of 13 of the 15 genera of the Hydrocharitaceae has been studied, and certain aspects of floral morphology are considered. The flowers of the family show a broad range of specialized structures combined with primitive characteristics. The origin of paired and single stamens is interpreted as probable modifications of fascicled stamens. Extreme reduction in the androccium is ...
متن کاملPhylogeny of Astragalus sect. Alopecuroidei based on the combined nrDNA ITS and morphology
A phylogenetic analysis of Astragalus sect. Alopecuroidei based on nrDNA ITS as well as morphological character data is presented. A total of fifty informative morphological characters were analyzed to reconstruct phylogenetic relationships for 23 taxa of the sect. Alopecuroidei and two species of sect. Laxiflori plus A. sieversianus and A. caryolobus as outgroups. The present analysis revealed...
متن کاملSubgeneric classification of Linaria (Plantaginaceae; Antirrhineae): molecular phylogeny and morphology revisited
Linaria Mill. (Plantaginaceae) with about 160 spp. is the largest genus of the tribe Antirrhineae. We conducted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer region (ITS) and chloroplast DNA (rpl32-trnL) sequence data to test the monophyly of currently recognized sections in Linaria. For this purpose 86 species representing seven sections of Linaria and one species ...
