“…Our emphasis on geographic range-wide diversification patterns enabled us to estimate relationships among almost all described Teratoscincus species and identify natural groupings within taxa. Congruent phylogenetic structure and monophyletic groups of species were recovered in previous studies of Teratoscincus [ 44 , 45 , 66 ], supported by studies incorporating other taxa (e.g., [ 33 – 35 , 46 , 67 ]), and corroborated by our study. We recovered monophyly of most recognised species, along with high genetic and geographic diversity within T .…”

Effective biodiversity conservation planning starts with genetic characterization within and among focal populations, in order to understand the likely impact of threats for ensuring the long-term viability of a species. The Wonder Gecko, Teratoscincus keyserlingii, is one of nine members of the genus. This species is distributed in Iran, Afghanistan, and Pakistan, with a small isolated population in the United Arab Emirates (UAE), where it is classified nationally as Critically Endangered. Within its Arabian range, anthropogenic activity is directly linked to the species’ decline, with highly localised and severely fragmented populations. Here we describe the evolutionary history of Teratoscincus, by reconstructing its phylogenetic relationships and estimating its divergence times and ancestral biogeography. For conservation implications of T. keyserlingii we evaluate the genetic structure of the Arabian population using genomic data. This study supports the monophyly of most species and reveals considerable intraspecific variability in T. microlepis and T. keyserlingii, which necessitate broad systematic revisions. The UAE population of T. keyserlingii likely arrived from southern Iran during the Pleistocene and no internal structure was recovered within, implying a single population status. Regional conservation of T. keyserlingii requires improved land management and natural habitat restoration in the species’ present distribution, and expansion of current protected areas, or establishment of new areas with suitable habitat for the species, mostly in northern Abu Dhabi Emirate.

“…The Przesalski's wonder gecko, Teratoscincus przewalskii, belonging to the subfamily Teratoscincinae (Squamata: Sphaerodactylidae), is known to be mainly distributed in Mongolia and Xinjiang, Gansu and Inner Mongolia in China (Gamble et al 2007(Gamble et al , 2011(Gamble et al , 2012Pyron et al 2013;Nazarov et al 2017). This species mostly lives in arid Gobi gravel sand, fixed dunes, semi-quicksand zones and Gobi Desert near reclaimed land.…”

“…Based on the complete mitochondrial genome of T. przewalskii and other 22 species of Gekkota, a phylogenetic tree was constructed using Maximum-likelihood (ML) method on RAxML v8.2.10 software (https://cme.h-its.org/exelixis/software.html)with 1000 bootstrap replicates (Stamatakis 2014). The result showed that T. przewalskii was most closely related to its congener T. keyserlingii and rooted with the other Gekkonidae species (Han et al 2004;Macey et al 2005;Harris and Rato 2008;Nazarov et al 2017) (Figure 1). This mitochondrial genome provides valuable molecular information for further research on species identification and molecular evolution.…”

The complete mitochondrial genome of the lizard, Teratoscincus przewalskii, which belongs to the family Sphaerodactylidae was determined based on Illumina data in this study. The result showed that the closed double-stranded circular mitogenome was 16,779 bp in total length (GenBank accession number: MW491837) with 44.07% GC. The complete mitochondrial genome consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal genes, and one noncoding control region. Phylogenetic analysis using mitochondrial genomes suggested that T. przewalskii was most closely related to its congener T. keyserlingii. This work provides valuable molecular information for further research on species identification and molecular evolution.

“…This increase in groundwater creates more vegetation growth in these sand habitats, reducing the open cover dune habitat. This reduction in open dune habitat increases interspecific competition between the endemic sand-dune-adapted species and surrounding non-sand-dune-adapted species, making conservation efforts ineffective [4,5]. The problem of preserving sand massif habitats in the Fergana Valley is further complicated by the fact that establishing the correct status and protection regime for these unprotected areas in Uzbekistan is technically quite difficult.…”

The high level of endemism in Fergana Valley has been well documented in numerous studies for various groups of animals and plants. In a relatively small area, there are 45 endemic plant species, five endemic insect species, and five endemic reptile species. In surveying this area for data on distribution, abundance, acoustics, and genetic samples for species of reptiles, we discovered two new species of gecko from the genus Alsophylax. Phylogenetic analyses of mitochondrial DNA sequences indicate the relatives of these new species are the even-fingered gecko, Alsophylax pipiens, and the southern even-fingered gecko, Alsophylax laevis, located hundreds of kilometers to the northwest and southwest of the Fergana Valley. The threats to these new endemic species are significant given the amount of continued agricultural development that involves new territories previously considered “unsuitable” for any species of significance that is leading to the further reduction in, fragmentation of, and degradation of the remaining natural ecosystems in the Fergana Valley. The conservation of these rare and locally endemic species depends directly on the readiness of the state to create areas with IUCN I and II protection. The many studies documenting levels of endemism, along with the data published in this study, are the basis for the justification for state-protected areas in the Fergana Valley.
