Thousands of Caspian seals (Phoca caspica) died in the Caspian Sea from April to August 2000. Lesions characteristic of morbillivirus infection were found in tissue specimens from dead seals. Canine distemper virus infection was identified by serologic examination, reverse transcriptase- polymerase chain reaction, and sequencing of selected P gene fragments. These results implicate canine diste...
A captive bred Ocadia sinensis x Cyclemys shanensis hybrid is described. Its hybrid status was confirmed by a comparison of a 1036 bp fragment of the mitochondrial cytochrome b gene with the putative mother (C. shanensis) and genomic ISSR fingerprinting. This is the first report of an intergeneric hybrid between very distantly related geoemydid turtles. All previous geoemydid intergeneric hybri...
Eight polymorphic microsatellite markers for Muntiacus reevesi were identified and characterized in this study. The number of alleles per locus ranged from 3 to 10 across 24-48 samples. The loci showed expected and observed heterozygosities of 0.577-0.876 and 0.387-0.933, respectively, with an average polymorphic information content value of 0.682. These markers should be a useful tool for furt...
از آنجا که خزندگان اهمیت فراوانی در شبکه حیات و اکوسیستم های خشکی دارند ما در این مطالعه به بررسی فون خزندگان و برخی جنبه های آناتومیکی و بافت شناسی یک گونه از سوسماران ساکن شرق استان لرستان پرداختیم. برای انجام این تحقیق سفرهای متعددی به مناطق مورد مطالعه که شامل شهرستان های درود، ازنا و الیگودرز بود انجام گرفت و طی آن نمونه های جانوری به طرق مختلف جمع آوری گردید. نمونه ها سپس در آزمایشگاه با ...
The Caspian lizard (Darevskia caspica) is a recently described endemic of the Hyrcanian forests Northern Iran. paper presents new data on reproductive biology D. caspica obtained in laboratory conditions. Breeding females have body length 53.4– 64.4 mm and mass 2.96–3.60 g. Females produce from one to three clutches per season, each which contains 1–6 eggs. these eggs 10.35–13.95 mm, width 6.19...
salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. this study was conducted to determine the ion exchanges in halocnemum strobilaceum and halostachys caspica in saline conditions. the...
Superoxide dismutase (SOD) responsible for dismutation of ROS produced in cell controls the aging and longevity of animals. An attempt has been made to report on sequence to structure analysis of the genes and proteins of SOD1 and SOD2 of freshwater turtles, Pelodiscus sinensis and Mauremys reevesii. Analysis of gene and protein sequences of these SODs retrieved from the NCBI database suggested...
The mechanism by which plants cope with salt stress remains poorly understood. The goal of this study is to systematically investigate the contribution and distribution of inorganic ions and organic compounds to the osmotic adjustment (OA) in the halophyte species Halostachys caspica. The results indicate that 100-200 mM NaCl is optimal for plant growth; the water content and degree of succulen...
