Influence of the geological history of the TransMexican Volcanic Belt on the diversification of Nolina parviflora (Asparagaceae: Nolinoideae)
نویسندگان
چکیده
Methods Twenty-eight populations (210 individuals) were sequenced for one nuclear (rpb2) and two chloroplast (trnL–F and psbA–trnH) DNA markers. Intraspecific phylogenetic relationships among haplotypes were reconstructed, and molecular dating, population genetic analyses and group testing were performed on the data. Isolation-by-distance analysis was conducted for the populations spanning the distribution of the species.

Ecological Speciation in Nolina parviflora (Asparagaceae): Lacking Spatial Connectivity along of the Trans-Mexican Volcanic Belt
The hypothesis of ecological speciation states that as populations diverge in different niches, reproductive isolation evolves as a by-product of adaptation to these different environments. In this context, we used Nolina parviflora as a model to test if this species evolved via ecological speciation and to explore current and historical gene flow among its populations. Nolina parviflora is a m...
متن کاملIn the Case of Maden Complex, Geochemical Constraints on the Origin and Tectonic Implication of Eocene Magmatism in SE Turkey
The origin and geodynamic setting of the Maden Complex, which is situated in the Bitlis–Zagros Suture Zone in the Southeast Anatolian Orogenic Belt, is still controversial due to lack of systematic geological and geochemical data. Here we present new whole rock major–trace–rare earth element data from the Middle Eocene volcanic rocks exposed in Maden Complex and discuss their origin in the ligh...
متن کاملOrigin and diversification of the Milla Clade (Brodiaeoideae, Asparagaceae): a Neotropical group of six geophytic genera.
The Milla clade currently comprises six genera of geophytic plants distributed from Arizona to Guatemala. Three genera (Behria, Jaimehintonia and Petronymphe) are monotypic while the remaining genera (Bessera, Dandya and Milla) contain from two to ten (Milla) species. Parsimony, Maximum Likelihood and Bayesian Inference analyses were conducted with plastid and nuclear DNA sequences from a total...
متن کاملUsing Magma Mixing/Mingling Evidence for Understanding Magmatic Evolution at Mount Bidkhan Stratovolcano (South-East Iran)
Mount Bidkhan stratovolcano is located in the central Iranian volcanic belt. It is composed of several types of pyroclastic deposits, lava flows and intrusive bodies. Textural and chemical characteristics of plagioclase phenocrysts from the eruptive products volcanic edifice, record complex magma mixing events over the lifetime of the volcano. Evidences such as xenocrystic high Al+Ti clinopyrox...

Morphological discrimination of geological top-formations is the supplemental procedure of geological mapping; so in situ measurements to register geomorphological data are unavoidable; though due to the impassable and fault cliffs field operations to visit all areas within a geological map is almost impossible. Microwave or radar remote sensing, via synthetic aperture radar (SAR) images is cap...
