Condensation water has been a recent focus in ecological hydrology research. As one of the main sources that maintains food chain arid regions, condensation significant impact on balance environments and plays an important role desert vegetation. This study takes drought areas high-salinity habitats as its focus—selecting Halostachys caspica (M.Bieb.) C.A.Mey. community mild, moderate, severe s...
In order to identify Daldinia species in Guilan province, several specimens were collected during 2011–13. A total of six taxa, including Daldinia caldariorum (on Morus alba); D. childiae (on Parrotia persica, Pterocarya fraxinifolia, Morus alba, Quercus sp., Prunus sp., Citrus sinensis, Gleditschia caspica, Buxus sempervirens, Carpinis betulus and Alnus subcordata); D. gelatinoides (on M. alba...
این مطالعه با هدف بررسی تأثیر کلن ها و گونه های مختلف صنوبر بر خاک تحت پوشش و اختلاف آنها از نظر میزان عناصر غذایی در لاشبرگ انجام شد. نمونه برداری خاک و لاشبرگ بر اساس طرح بلوک های کامل تصادفی با پنج تیمار 18 ساله با فاصله کاشت 4×4 متر شامل کلن ها و گونه های populus euramericana triplo ،,populus deltoides 69/55 ,populus deltoides 63/51 euramericana 45/51 populus و گونه populus caspica به عنو...
The studies were carried out on the territory of State National Natural Park «Kulsai Lakes», located northern macroslope Kungei Alatau ridge. main dominant species plant communities southern slopes mountains with bedrock outcrops at altitudes 1600-2000 m a. s. l. have been identified. These are shrubs - Juniperus sabina, Cotoneaster melanocarpus, Ephedra intermedia, Artemisia gmelinii. Dominant...
BACKGROUND Many RNA viruses arise from animal reservoirs, namely bats, rodents and insectivores but mechanisms of virus maintenance and transmission still need to be addressed. The bicolored white-toothed shrew (Crocidura leucodon) has recently been identified as reservoir of the neurotropic Borna disease virus 1 (BoDV-1). PRINCIPAL FINDINGS Six out of eleven wild living bicoloured white-toot...
The Quaternary cold periods in Europe are thought to have heavily influenced the amount and distribution of intraspecific genetic variation in both animals and plants. The phylogeographies of 10 taxa, including mammals (Ursus arctos, Sorex spp., Crocidura suaveolens, Arvicola spp.), amphibians (Triturus spp.), arthropods (Chorthippus parallelus), and plants (Abies alba, Picea abies, Fagus sylva...
نوع پوشش گیاهی می تواند با تغییر مقدار کربن ورودی به خاک بر ذخیره کربن آلی و خصوصیات فیزیکی و شیمیایی خاک تاثیر بسزایی داشته باشد. به منظور بررسی تاثیر نوع پوشش گیاهی بر ذخیره کربن آلی و ویژگی های خاک، منطقه ای با چهار نوع پوشش گیاهی مختلف در ایستگاه تحقیقاتی صنوبر صفرابسته استان گیلان انتخاب گردید. در این منطقه علاوه بر دو نوع پوشش گیاهی بومی که populus caspica و taxodiumdistichum بودند، دو پو...
The greater white-toothed shrew (Crocidura russula) is an invasive mammalian species that was first recorded in Ireland in 2007. It currently occupies an area of approximately 7,600 km2 on the island. C. russula is normally distributed in Northern Africa and Western Europe, and was previously absent from the British Isles. Whilst invasive species can have dramatic and rapid impacts on faunal an...
