SINGLETON MOLECULAR SPECIES DELIMITATION BASED ON COI-5P BARCODE SEQUENCES REVEALED HIGH CRYPTIC/UNDESCRIBED DIVERSITY FOR CHINESE KATYDIDS (ORTHOPTERA: TETTIGONIIDAE)

Singleton molecular species delimitation based on COI-5P barcode sequences revealed high cryptic/undescribed diversity for Chinese katydids (Orthoptera: Tettigoniidae)

Abstract Background DNA barcoding has been developed as a useful tool for species discrimination.Several sequence-based species delimitation methods, such as Barcode Index Number (BIN), REfined Single Linkage (RESL), Automatic Barcode Gap Discovery (ABGD), a Java program uses an explicit, determinate algorithm to define Molecular Operational Taxono

Application of EMPA-XRD-SEM to Study the Mineralogical Characteristics of Turquoise from Xichuan, Henan Province

BACKGROUND The Xichuan turquoise mining area in Henan Province belongs to the east extension of the turquoise metallogenic belt in the junction of Hubei and Shaanxi Provinces.A lot of turquoise artifacts have been excavated in many early Snacking archaeological sites near Xichuan.Therefore, the distribution of the Xichuan turquoises has attracted w
