مقاله حاضر بخشی از بررسی وسیع جنسRhizocarpon Ramond ex DC.بر اساس جمعآوری انجام شده در طول سال 2007 از استان خراسانرضوی واقع در شمالشرق ایران میباشد. جزئیات مورفولوژی، آناتومی و ترکیبات گلسنگی برخی نمونههای R. macrosporum در اینجا آمده است. نقشه توزیع گونه نیز ارائه میگردد.
489–497). Three papers utilize molecular phylogenetic approaches to systematics. Traditional groupings and most species of Physconia are confirmed as distinct, although doubt is shed on the monophylly of two species pairs (pp. 498–505). The Lecanora rupicola group is shown to be distinct from Lecanora s. str., with the species containing sordidone as well as having pruinose apothecial discs (pp...
Community science-generated biodiversity data can provide essential information for understanding species distributions, behaviors and conservation statuses. However, their utility be limited due to high uncertainty variability in quality, especially small taxonomically difficult organisms like fungi insects. One important set of community-generated that are increasingly used by scientists Rese...
This experiment was aimed at establishing, for the first time, the survival capability of lichens exposed to space conditions. In particular, the damaging effect of various wavelengths of extraterrestrial solar UV radiation was studied. The lichens used were the bipolar species Rhizocarpon geographicum and Xanthoria elegans, which were collected above 2000 m in the mountains of central Spain an...
The effectiveness of lichens in degrading their rock substrates, leading to the first stages in the formation of soil, has long been discussed and opinions have varied widely (Jones, 1988; Syers & lskandar, 1973). Nevertheless, it is generally recognized that lichen encrusted rocks provide an ideal environment for studying the biological weathering of minerals since, unlike the situation in soi...
