A new class, Carici arctisibiricae–Hylocomietea alaskani class nov. is described for vegetation of the tundra zone on a circumpolar scale. This higher unit in system Braun-Blanquet floristic (= floristic-sociological) classification unites zonal intermediate habitats with respect to substrate moisture, pH and texture, snow cover thickness duration, depth seasonal frozen ground thawing, growing ...

To allow for information on successional changes in phytodiversity over time and space, as well as information on differences between clones and treatments, phytodiversity was monitored on a poplar short rotation coppice plantation in Oberschwaben, Southwest Germany, in four consecutive years. The investigated plantation was divided into two core areas, one planted with poplar clone Max4, the o...
Rift Valley fever (RVF) is endemic in Africa and parts of the Middle East. It is an emerging zoonotic disease threat to veterinary and public health. Outbreaks of the disease have severe socio-economic impacts. RVF virus emergence is closely associated with specific endorheic wetlands that are utilized by the virus' mosquito vectors. Limited botanical vegetation surveys had been published with ...
Knowledge about plant communities and their relationships with ecological factors is one of the most important issues in conservation ecology particularly in the recent decades. The current investigation aimed to study the vegetation ecology of Palangan habitat in Aghdagh Protected area, Ardabil province. In order to collect species and environmental data, a total of 45 plots along a 1500 m ele...
اکوسیستم‌های شور ایران به خاطر فعالیت‌های تخریبی انسان و دام در معرض تخریب قرار گرفته‌اند و پروژه‌های حفاظت، نگهداری و استقرار مجدد این اکوسیستم‌ها بدون بررسی جوامع گیاهی و عوامل محیطی امکان‌پذیر نخواهد بود. شوره‌زارهای جنوب شرقی دریاچهی ارومیه با وسعتی بیش از 85000 هکتار در عرض شمالی 37 درجه الی 37 درجه و 37 دقیقه و طول شرقی 45 درجه و 35 دقیقه الی 46 درجه و 2 دقیقه با ارتفاع متوسط 1284 متر...
Exclusion and not using of rangeland in the long term affects the composition and homogeneity of vegetation and consequently leads to the improvement of plants status. In this study, the characteristics and structural changes of the rangeland of Gonbad, Hamadan province, Iran, in 2014 (after 20 years of enclosure) were evaluated using Braun-Blanquet plot, Phytosociology and multivariate analysi...

whenever |ζ1|, . . . , |ζn| ≤ 1 . In 1974 [11] Sunada investigated the structure of bounded Reinhardt domains containing the origin from the viewpoint of biholomorphic equivalence. He was able to describe completely the symmetric Reihardt domains which, up to linear isomomorphism, turned to be direct products of Euclidean balls. Our aim in this paper is to study infinite dimensional analogs of ...
