A new colubrid snake, Rhynchocalamus ilamensis sp. nov., is described from Ilam province, western Iran. The species differs other congeners using both morphological and molecular analyses. Morphologically, the head neck color patterns are most obvious distinguishing traits of this its congeners. separated by a genetic distance 9–13% in mitochondrial Cytb gene, with R. satunini melanocephalus as closest farthest relatives, respectively. As well, color-based revised key to genus provided.
During past years different studies have attempted to describe the tetrapod fauna of Iran, most which focused on herpetofauna. However there is no coherent study endemic species Tetrapoda in Iran. In this study, we provide a list mention their habitat, distribution, conservation status (IUCN) and important biological note. Eighty occur 82.50% are reptiles. Thirty-eight (47.50% total Tetrapoda) submitted data IUCN; 35 Additional needed about especially fauna.
A new species of Dwarf Snakes, Eirenis rafsanjanicus sp. n., is described from south-central Iran. This well distinguished other congeners in both molecular and morphological characters, its description increases the number to 26. n. genetically closest (6% Cytb) recently E. yassujicus, which inhabits high habitats southern Morphologically, more similar modestus than congeners. revised key genus presented.
Abstract Background The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects shared venom system. Morphological included partitioning mixed ancestral glands into two discrete devoted for production or mucous respectively, as well location, size structural elements venom-delivering teeth. Evidence also exists homology among gland toxins expressed across snakes. However, despite evolutionary novelty snake venoms,...
We examined habitat preferences and nesting requirements of sympatric populations Middle Spotted Woodpecker (Dendrocoptes medius) Syrian (Dendrocopos syriacus). carried out our study in 2015–2018 natural mountain forests Southwest Iran. compared selected features nesting, territory, outside territory tree stands the studied woodpeckers. The occupied only oak forests, but inhabited heterogenic that included preferred this species, Mount Atlas Mastic. recorded breeding territories Woodpecker,...
Pseudocerastes urarachnoides is a fascinating viper and as yet has been reported only in western Iran. An elaborated arachnid-like caudal structure unique feature of this viper, hence gives it the common name “Iranian spider-tailed viper”. During tail wagging, reminiscent moving spider. Tail movements are used for two different purposes snakes: defense via vibration hunting both luring distraction. Caudal snakes wriggling or wagging posterior part tail, presence potential prey, with...
Snakes of the genera Pseudocerastes and Eristicophis (Viperidae: Viperinae) are known as desert vipers due to their association with arid environments Middle East. These species have received limited research attention little is about venom or ecology. In this study, a comprehensive analysis viper venoms was conducted by visualising proteomes via gel electrophoresis assessing crude for cytotoxic, haemotoxic, neurotoxic properties. Plasmas sourced from human, toad, chicken were used models...
To date, at least 72 endemic reptilian species have reported from Iran including the Spider-tailed Viper (Pseudocerastes urarachnoides), which has a very limited, narrow distribution, and occurs in areas of western eastern Iraq. The potential distribution Pseudocerastes urarachnoides for present, past (mid- Holocene last glacial maximum), future (2100) was predicted by Maximum Entropy (MaxEnt) modelling using 99 occurrence records as well 19 environmental variables derived climate databases....
Venoms are a rich source of potential lead compounds for drug discovery, and descriptive studies venom form the first phase biodiscovery process. In this study, we investigated pharmacological crude Pseudocerastes Eristicophis snake venoms in haematological disorders cancer treatment. We assessed their antithrombotic using fibrinogen thromboelastography, gels with without protease inhibitors, colourimetric fibrinolysis assays. These assays indicated that anticoagulant properties likely...
An Iranian viper, Pseudocerastes urarachnoides , was collected alive during fieldwork in April 2008. The viper transferred to the lab where many observations were made of its biology, behavior, feeding, habitat and distribution. During this survey we verified previous speculation that tail ornament (knob-like structure) is used as a lure attract prey. Distribution extended from Kermanshah Province Khuzestan Province.
After description of Pseudocerastes urarachnoides from western Iran, and based on new evidence, elevation both traditional subspecies persicus ( P. p. fieldi ) to the specific level (i.e., was further supported. With regards these taxonomic changes, we decided make a key species this genus obvious morphological differences.
Abstract The genus Pseudocerastes comprises three species of false‐horned vipers: P. fieldi , persicus and urarachnoides . were once regarded as two subspecies the same species. Recent morphological, molecular toxicological studies elevated these to rank. Upon discovery a third species, phylogeny systematic relationships within this based on morphology complicated. A total 113 specimens across Middle‐East used perform phylogenetic biogeographic study. Using both mitochondrial (16S Cytb)...
The false horned vipers of the genus Pseudocerastes consist 3 species; all have been recorded in Iran. These include persicus, P. fieldi, and urarachnoides. Morphologically, taxonomic border between fieldi persicus is not as clear that urarachnoides or fieldi. Regarding weak diagnostic characters differentiating from very robust separating both, there may arise some uncertainty exact status whether it should remain at current specific level be elevated to a distinct genus. Based on our...
Skeletochronology is a reliable method for estimating the age and growth rate of many ectothermic vertebrates, including amphibians. The Levant green frog, Pelophylax bedriagae (Ranidae), relatively large frog distributed in western northern parts Iran. structure was determined by examining 52 females 39 males collected from Kohgilouyeh Bouyerahmad Provinces (Yasouj Basht). range two populations three to 10 years. maximum eight years, respectively. highest distribution six years (17.6%) four...
In this study, 68 specimens of the Levant Green Frog, Pelophylax bedriagae, were collected from agricultural fields around Yasouj and Noor-Abad cities, August 2018 to May 2019 in southern Iran investigate blood cell morphology. Blood taken heart, or abdominal facial veins. Smears dried room temperature, fixed by methanol stained using Giemsa method. cells (erythrocytes leucocytes) counted measured light microscopy under an optical micrometer. Based on findings erythrocytes population has...
In this study, the skull roof, palate, braincase, lower jaw and dentition of adult specimens two species ground agamids, Trapelus ruderatus lessonae are compared for first time. Based on from morphological functional perspectives, some fine differences among various parts in these lizard presented.
Using the stomach flushing technique, a total of 188 specimens Marsh Frog, Pelophylax ridibundus, were flushed, which 129 had at least one food item in stomach. The diet consisted Annelida, Mollusca, Arthropoda and Chordata with being most abundant group. Both volume number items per significantly larger April than August. proportion frequency occurrence (FOi%) categories did not show constant flushed materials. ridibundus prefers Diptera, Coleoptera, Amphipoda Hymenoptera over other...

This cave is a part several large cavities created as result collapse karst formation. has exposed aquifer two adjacent deep caves. The caves are about 100 meters away from small village with same name. area around extensively altered for agriculture purposes almost nothing left natural vegetation cover except depth high valleys. weather condition this characterized by hot dry summer winter no freezing...
The Arabian Horned Viper, Cerastes gasperettii, is distributed along the eastern edge of Sinai Peninsula south and east across to Iraq, Kuwait western Iran comprising two subspecies: Cerastes. g. mendelssohni in Arava valley (Israel Jordan) C. gasperettii southwestern Iran. Phylogenetic relationships based on Maximum Likelihood, Bayesian Inference, haplotype networks, genetic divergence among different populations are analysed this study.
