Following the abolishment of dual nomenclature, Stilbospora is recognised as having priority over Prosthecium. The type species of Stilbospora, S. macrosperma, is the correct name for P. ellipsosporum, the type species of Prosthecium. The closely related genus Stegonsporium is maintained as distinct from Stilbospora based on molecular phylogeny, morphology and host range. Stilbospora longicornu...
برای مدیریت صحیح اکوسیستم های جنگلی داشتن اطلاعات کافی در رابطه با ساختار گونه های درختی ضروری می باشد. در این تحقیق، ساختار گونه های درختی تیپ های راش (fagus)، راش-ممرز (fagus-carpinus)، ممرز-راش (carpinus-fagus) و ممرز-بلوط (carpinus-quercus) جنگل های هیرکانی مورد بررسی و مقایسه قرار گرفت. اطلاعات مورد استفاده برای این تحقیق، با استفاده از 239 قطعه نمونه 1000مترمربعی که به روش منظم تصادفی در ...
Since the early 2000s, reports on declining hornbeam trees (Carpinus betulus) are spreading in Europe. Two fungi involved decline phenomenon: One is Anthostoma decipiens, but other etiological agent has not been identified yet. We examined morphology, phylogenetic position, and pathogenicity of yellow fungal isolates obtained from Austria, Georgia Switzerland, compared data with disease norther...
To implement correct management of forest ecosystems, enough information in relation to the structures of tree species is necessary. In this study, the structures of trees species in Fagus, Fagus-Carpinus, Carpinus-Fagus and Carpinus-Quercus types were investigated and compared in Hyrcanian forest. The data used in this study was collected from 239 plots with an area of 1000 m2 in Gorazbon dist...
Forest type maps play a significant role in sustainable forest management. For many years aerial photos and satellite data were a primary data source supporting forest type mapping. Recent developments in remote sensing provide opportunities to further enhance forest type maps by introducing variations of spectral, biochemical and biophysical properties at various scales. A structural sampling ...
BACKGROUND AND AIMS Litter is a key factor in structuring plant populations, through positive or negative interactions. The litter layer forms a mechanical barrier that is often strongly selective against individuals lacking hypocotyle plasticity. Litter composition also interacts with plant growth by providing beneficial nutrients or, inversely, by allowing harmful allelopathic leaching. As co...
