Himalayan-Tibetan Plateau Uplift Drives Divergence of Polyploid Poppies: Meconopsis Viguier (Papaveraceae)
Meconopsis Viguier (Papaveraceae) is an iconic genus of alpine forbs that includes medicinal and ornamental species. This study extends previous phylogenetic analyses of Meconopsis, using ITS sequences representing all the major Meconopsis clades. Phenotypic traits are also analysed for all described species. Our results show that Meconopsis evolved as a ≥ octaploid clade, with considerable int...
متن کاملPhylogenetic Analysis of Meconopsis (papaveraceae) and Evaluation of Two Controversial Taxonomic Species
Meconopsis is a genus native to the high elevation habitats that range from the western Himalaya eastward to the Hengduan Mountains (China). The genus has been the subject of several taxonomic treatments and monographs by generations of botanists, which has led to a long and confusing taxonomic history with inconsistent species concepts and conflicting interpretations of relationships among nam...
متن کاملMolecular Phylogeny of Asian Meconopsis Based on Nuclear Ribosomal and Chloroplast DNA Sequence Data
The taxonomy and phylogeny of Asian Meconopsis (Himalayan blue poppy) remain largely unresolved. We used the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) and the chloroplast DNA (cpDNA) trnL-F region for phylogenetic reconstruction of Meconopsis and its close relatives Papaver, Roemeria, and Stylomecon. We identified five main clades, which were well-supported in th...
متن کاملEcological equivalency as a tool for endangered species management.
The use of taxon substitutes for extinct or endangered species is a controversial conservation measure. We use the example of the endangered California tiger salamander (Ambystoma californiense; CTS), which is being replaced by hybrids with the invasive barred tiger salamander (Ambystoma mavortium), to illustrate a strategy for evaluating taxon substitutes based on their position in a multivari...
متن کاملCYTOTAXONOMIC STUDIES IN WEST HIMALAYAN BRYACEAE (MUSCI)
The meiotic chromosomes of 10 species (Pohlia elongata, Anomobryum cymbifolium, Brachymenium acuminatum, B. ochianum, B. sikkimense, Bryum cellulare, B. pseudotriquetrum, B. apiculatum, B. capillare and B. atrovirense), in four genera of the family Bryaceae of acrocarpous mosses are studied with special emphasis on their evolution, polyploidy and cytological features with reference to interrela...
