Mycorrhizal densities decline in association with nonnative plants and contribute to plant invasion.
Belowground interactions between herbaceous native species and nonnative species is a poorly understood but emerging area of interest to invasive-species researchers. Positive feedback dynamics are commonly observed in many invaded systems and have been suspected in California grasslands, where native plants associate strongly with soil mutualists such as arbuscular mycorrhizal fungi. In respon...
متن کاملتنوع درون گونه ایCarduus pycnocephalus L. بر اساس مارکرهای فلورستیک ، اکولو‍‍ژیک و پروتئین های ذخیره ای بذر در استان همدان
تیره کاسنی یا مرکبان (Asteraceae) یکی از تیره‌های بزرگ گیاهی است که بسیاری از گیاهان آن با شرایط آب و هوایی ایران بخوبی سازش یافته و بطور وسیع در ایران پراکندگی دارند. این پژوهش با هدف بررسی وجود تنوع درون گونه‌ای Carduus pycnocephalus در استان همدان با روش تعیین زیستگاه ویژه (D.S.S ) (Determination of Special Station) صورت پذیرفت. بر این اساس ۱۴ زیستگاه ویژه برای این گونه انتخاب گردید. در بررس...
متن کاملRhinocyllus conicus -- Insights to Improve Predictability and Minimize Risk of Biological Control of Weeds
A review of information on the release of Rhinocyllus conicus to control of Carduus spp. thistles in North America suggests at least 8 lessons for future biological control efforts. These lessons include the need for: 1) better a priori quantification of the occurrence and ecological effects of the weed; 2) improved incorporation of ecological criteria to supplement the phylogenetic information...
متن کاملResveratrol Provides Cardioprotection after Ischemia/reperfusion Injury via Modulation of Antioxidant Enzyme Activities
In this study, we investigated the cardioprotective effects of resveratrol. Rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. Isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...
