The small intestines of 6 species of rodents and 1 species of insectivore were examined seasonally for Plagiorchis muris infection in 3 different localities in northern Gyeonggi-do (Province), near the demilitarized zone (DMZ). A total of 1,496 animals, including 1,366 Apodemus agrarius, 54 Crocidura lasiura (insectivore), 32 Mus musculus, 28 Micronytus fortis, 9 Eothenomys regulus, 6 Micronys ...
Insects use various types of behaviour, chemical defences, mimetic, aposematic or cryptic appearances as anti-predatory strategies. Among insects, carabid beetles of the genus Brachinus are distasteful prey because they discharge an irritating "cloud" of quinones when threatened. These beetles live in aggregations and adopt warning (conspicuous pattern) colours and chemicals to create a templat...
degradation of natural habitats and decreasing of genetic diversity of populus caspica led to vast reduction of its regeneration and growth potential in north of iran. hence, the growth potential of mass-produced seedlings was compared with their parents. for this purpose, the ramets of three selected seedlings from 17 parent trees belonging to north of iran, along with ramets of their parent t...
این پژوهش به منظور بررسی امکان دورگگیری بین جنسی در خانواده بید از طریق بکارگیری روشهای نوین بیوتکنولوژی انجام گرفت. بدین منظور تلاقی بین دو جنس صنوبر و بید با استفاده از گونههایsalix alba و populus caspica بر روی تخمدانهای ایزوله از گردههای بیگانه انجام گرفت. تکنیک نجات جنین (کشت تخمدان)، جهت جوانهزنی رویانها بکار گرفته شد و تخمدانها به محیط کشت ms جامد در فواصل 10، 14 و 21 روز انتق...
The changes in the axon and growth cone numbers in the optic nerve of the freshwater turtle Mauremys leprosa were studied by electron microscopy from the embryonic day 14 (E14) to E80, when the animals normally hatch, and from the first postnatal day (P0) to adulthood (5 years on). At E16, the first axons appeared in the optic nerve and were added slowly until E21. From E21, the fibre number in...
Tropical montane taxa are often locally adapted to very specific climatic conditions, contributing to their lower dispersal potential across complex landscapes. Climate and landscape features in montane regions affect population genetic structure in predictable ways, yet few empirical studies quantify the effects of both factors in shaping genetic structure of montane-adapted taxa. Here, we con...
Although macrobenthic assemblages are considered as major players in many ecosystems around the world, the ecology of Caspian Sea macrobenthos is currently understudied. This study describes the species composition and quantitative distribution of macrobenthos in the southern Caspian Sea and relates the distribution to seasonal changes at three depths (1, 5 and 10 meters) on the Boojagh Marine ...
این پژوهش برای تعیین ارزش غذایی گونه شوررویHalostachys caspica در سه مرحله فنولوژیکی رشد رویشی، گلدهی و بذردهی در سه رویشگاه متفاوت قم، یزد و ارومیه انجام گردید. پس از نمونهبرداری کاملاً تصادفی، شاخصهای دیواره سلولزی عاری از همیسلولز ((ADF، پروتئین خام (CP)، میزان خاکستر، چربی خام (EE)، انرژی متابولیسمی (ME)، هضمپذیری ماده خشک ((DMD و درصد رطوبت در آزمایشگاه با روشهای استاندارد تعیین شدند. بر...
