 Located in the Semna?n area (midway between Tehran and Khorasan), town of S?ahmirza?d its neighboring villages are home to speakers S?ahmirza?di, a vernacular sharply differing from other language types spoken but closely related Mazandarani across Alborz range north, along Caspian coast. This article studies S?ahmirza?di phonology, grammar, vocabulary, with look at cross-linguistic infl...
A major challenge facing biodiversity conservation and management is that a significant portion of species diversity remains undiscovered or undescribed. This is particularly evident in subterranean animals in which species delimitation based on morphology is difficult because differentiation is often obscured by phenotypic convergence. Multilocus genetic data constitute a valuable source of in...
The genus Eois comprises an important part of megadiverse assemblages of geometrid moths in mountain rainforests of southern Ecuador. In this study we report: (i) on the construction of a DNA barcode library of Eois for identification purposes; and (ii) the exploration of species diversity through species delimitation by pair-wise distance thresholds. COI barcode sequences were generated from 4...
The historical distribution of the cheetah Acinonyx jubatus extended from Africa through the Arabian Peninsula into Iran and Afghanistan. From there, the range continued eastwards to Pakistan and India, and northeast through Central Asia: Uzbekistan, Kazakhstan and Turkmenistan (Nowell & Jackson 1996). During the Middle Ages, cheetahs also occurred to the west of the Caspian Sea, in Transcaucas...

Connectivity among populations determines the dynamics and evolution of populations, and its assessment is essential in ecology in general and in conservation biology in particular. The robust basis of any ecological study is the accurate delimitation of evolutionary units, such as populations, metapopulations and species. Yet a disconnect still persists between the work of taxonomists describi...
This article describes a new package called STACEY for BEAST2 which is capable of both species delimitation and species tree estimation using DNA sequences from multiple loci. The focus in this article is on species delimitation. STACEY is based on the multispecies coalescent model, and builds on earlier software (DISSECT), which uses a ‘birth-death-collapse’ prior to deal with delimitations wi...
