Bu çalışma, metabolik ve oksidatif stres biyobelirteçlerinin analizi yoluyla, su kirliliğinin iyi bir biyoindikatörü olarak kabul edilen tatlı omurgasızı Dreissena polymorpha üzerindeki Gadolinyum (Gd) toksisitesini değerlendirmeyi amaçlamaktadır. Öncelikle çalışmamızda Gd’nin D. LC50 değeri belirlenmiştir. polymorpha, kontrollü koşullar altında 24 96 saatlik süre boyunca üç letal olmayan Gd ko...

The role of intraspecific trait variation in functional ecology has gained traction recent years as many papers have observed its importance driving community diversity and ecology. Yet much the work this field relies on field-based surveys. Here, we used continuous canopy information derived from remote sensing data a highly polymorphic tree species, Metrosideros polymorpha, to quantify enviro...
the preliminary result of a survey conducted on xylaria species in the north of iran is presented. based on morphological examination of fungal specimens collected from guilan, mazandaran and golestan provinces, eight species including xylaria arbuscula, x. cubensis, x. filiformis, x. hypoxylon, x. longipes, x. multiplex, x. pannosa, and x. polymorpha were identified. among the identified speci...
Ensifer medicae WSM1369 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago. WSM1369 was isolated in 1993 from a nodule recovered from the roots of Medicago sphaerocarpos growing at San Pietro di Rudas, near Aggius in Sardinia (Italy). WSM1369 is an effective microsymbiont of the annual forage legumes M. polymo...
برای بررسیتولید علوفه یونجه های یکساله در شرایط دیم گرگان، آزمایشی در طرح بلوک کامل تصادفی در چهار تکرار طی دو سال در ایستگاه تحقیقات چالکی در سالهای81 و82 اجرا شد. یونجه های یکساله شامل: یک گونه بومی به عنوان شاهد: m. minima و هفت رقم m. polymorpha cv. spinless و (mogulوmedicago truncatula cv (caliph m. scutellata cv. (sava, robinson), و cv. orion.sphaerocarpos .m. littoralis cv. heral...
کشت متوالی غلات در بسیاری از مناطق دنیا، سطح نیتروژن خاک را به حدی کاهش داده است که در حال حاضر تولیدات گیاهی به کود نیتروژنه بسیار وابسته است. معرفی لگومها و سوشهای ریزوبیومی که همزیستی مؤثری با هم داشته باشند باعث افزایش تولید علوفه غنی از پروتئین میشود و همچنین باعث اصلاح ساختار خاک میگردد. چهار گونه یونجه یکساله ((Medicago littoralis, M. polymorpha, M. rigidula, M. truncatula, در ترکیب...
Cell suspensions of Marchantia polymorpha hydrogenate progesterone to 5alpha-pregnane-3,20-dione. Structure elucidation of the product was achieved by comprehensive NMR analyses.
Ornamental aquaculture is one of the main sources non-native species worldwide. Unintentionally transported “hitchhiking” organisms have been previously recorded; although most these are from tropical regions, here we report on first accidental transport zebra mussel (Dreissena polymorpha) in a shipment ornamental Aegagropila linnaei (Chlorophyta) Russia to Czech Republic. This invasive listed ...
