چکیده در این پژوهش منشاء خزندگان را مورد بررسی قرار داده، خانواده های سوسماران را در ایران معرفی نموده و ویژگی های آنها را ذکر کرده ایم، علاوه بر این نکات، اهمیت تغییرات در وضعیت سیستماتیک mabuya (sensu lato) را بررسی کردیم. خانواده scincidae را از نظر فیلوژنی، رده بندی و همچنین جنس های آن را، مرور کرده ایم. جنس trachylepis fitzinger, 1843 که هدف اصلی پژوهش حاضر است در ایران دارای سه گونه می ب...
the genus trachylepis fitzinger, 1843 encompasses two-three species in iran: trachylepis vittata (olivier, 1804) distributed in western iran, west of the zagros mountains; t.septemtaeniata (reuss, 1834) in southern regions of the zagros mountains and t. aurata transcaucasica chernov, 1926 from northern to central parts of the zagros mountains. for study of geographic variation in the latter two...
western iran in general and ilam province in particular, has unique geographical and climatic conditions that support a rich flora and fauna. in view of the lack of in-depth studies of lizards of the region, an investigation was initiated in most areas of ilam province for an inventory of lizard species and their habitats. a total of 189 specimens were collected and identified from may 2005 to ...
AsIII uptake in living cells is through aquaglyceroporin transporters, but it is unknown in arsenic-hyperaccumulator Pteris vittata. We investigated the effects of AsIII analogs glycerol and antimonite (SbIII) at 0-100 mM and aquaporin inhibitor AgNO(3) at 0-0.1 mM on the uptake of 0.1 mM AsIII or AsV by P. vittata over 1-2 h. Glycerol or SbIII didn't impact AsIII or AsV uptake by P. vittata (p...
The roles of low-molecular-weight thiols (LMWTs), such as glutathione and phytochelatins, in arsenic (As) tolerance and hyperaccumulation in Pteris vittata an As-hyperaccumulator fern remain to be better understood. This study aimed to thoroughly characterize LMWT synthesis in P. vittata to understand the roles played by LMWTs in As tolerance and hyperaccumulation. LMWT synthesis in P. vittata ...
Skinks account for more than 25% of all lizard species; however, representatives of fewer than a quarter of all species have been characterized osteologically. All but a few of the available cranial descriptions concentrate solely on characters that can be seen externally on the intact skull. Mabuyid skinks of the genus Trachylepis are the dominant, fully limbed skinks in Sub-Saharan Africa, an...
Plant species capable of hyper-accumulating heavy metals are of considerable interest for phytoremediation, and differ in their ability to accumulate metals from the environment. This work aims to examine (i) arsenic accumulation in three fern species [Chinese brake fern (Pteris vittata L.), slender brake fern (Pteris ensiformis Burm. f.), and Boston fern (Nephrolepis exaltata L.)], which were ...
Intestinal helminths are reported from four species of scincid lizards from southern Africa: Mabuya occidentalis, Mabuya spilogaster, Mabuya striata and Mabuya variegata. The helminth fauna consisted of one species of Cestoda, Oochoristica truncata and five species of Nematoda, Abbreviata paradoxa, Maxvachonia dimorpha, Parapharyngodon rotundatus, Spauligodon petersi and Thubunaea fitzsimonsi. ...
Arsenate interferes with enzymatic processes and inhibits inorganic phosphorus (Pi) uptake in many plants. This study examined the role of phytase and phosphatase in arsenate tolerance and phosphorus (P) acquisition in the arsenic hyperaccumulator Pteris vittata . Enzyme-mediated hydrolysis of phytate in P. vittata extracts was not inhibited by arsenate at 5 mM or by heating at 100 °C for 10 mi...
Skinks of the genus Eutropis represent one of the most widespread and speciose lizard groups in tropical Asia. Numerous recent studies have utilized a variety of genes and methods to reconstruct the phylogeny of these lizards, however these studies have not resolved the placement of one of the widely distributed Eutropis Fitzinger, E. dissimilis. We have sequenced a specimen of E. dissimilis fr...
