Molecular phylogeny and diversification history of Prosopis (Fabaceae: Mimosoideae) [PDF]

, 2008
The genus Prosopis is an important member of arid and semiarid environments around the world. To study Prosopis diversification and evolution, a combined approach including molecular phylogeny, molecular dating, and character optimization analysis was ...

Two New Potential Barcodes to Discriminate Dalbergia Species. [PDF]

PLoS ONE, 2015
DNA barcoding enables precise identification of species from analysis of unique DNA sequence of a target gene. The present study was undertaken to develop barcodes for different species of the genus Dalbergia, an economically important timber plant and ...

Some more amplituhedra are contractible

, 2019
The amplituhedra arise as images of the totally nonnegative Grassmannians by projections that are induced by linear maps. They were introduced in Physics by Arkani-Hamed \& Trnka (Journal of High Energy Physics, 2014) as model spaces that should provide ...

Applicability of rbcL, matK, and trnK Regions in Identification of Scopellaria marginata (Blume) W.J.de Wilde & Duyfjes (Cucurbitaceae) [PDF]

Brazilian Archives of Biology and Technology
East Java, Indonesia, has been identified as a new distribution area for Scopellaria marginata (Blume) W.J.de Wilde & Duyfjes (Cucurbitaceae) based on morphological evidence. To confirm this finding, molecular validation through DNA barcoding is required

A Complete Characterization of Irreducible Cyclic Orbit Codes and their Pl\"ucker Embedding [PDF]

, 2012
Constant dimension codes are subsets of the finite Grassmann variety. The study of these codes is a central topic in random linear network coding theory. Orbit codes represent a subclass of constant dimension codes.

Using matK sequence data to unravel the phylogeny of Casuarinaceae [PDF]

Molecular Phylogenetics and Evolution, 2003
Casuarinaceae are a Gondwanic family with a unique combination of morphological characters not comparable to any other family. Until recently, the 96 species in the family were classified in a single genus, Casuarina s.l. A recent morphological revision of the family resulted in the splitting of Casuarina s.l.
