The Caspian (Hyrcanian) lowland forest zone in northern Iran is characterized by small remnant alder forest communities, dominated or subdominated with an Euxino-Hyrcanian element, Alnus glutinosa ssp. barbata. The first floristic inventory of these alder forests in northern Iran is presented. The floristic catalogue is based on the data of 133 phytosociological releves in eight different alder...

Traditional techniques to map vegetation communities are by aerial photography interpretation and intensive field sampling. Semi-automated methods, including pixel and object-based image classification, demonstrate potential to accurately map vegetation communities, however, there is a lack of comparative research. This study is a component of a broader research project that compares several te...

Livestock exerts direct and indirect effects on plant communities, changing colonization and extinction rates of species and the surrounding environmental conditions. There is scarce knowledge on how and to what extent these effects control the floristic and functional composition of plant communities in grasslands. We performed an experiment that included several treatments simulating tramplin...

This paper presents an operational methodology to map and analyze the floristic richness of “target species” in Natura 2000 sites, making use G.I.S. tools procedures. A Floristic diversity (scale 1:50,000), covering area 612 km2, was produced by a team experts as part management plans “Madonie Mountains” Sites Community Importance (SCIs), located Sicily (Italy). The primary grid represents spec...

The objective of this study was to characterize the floristic composition, vegetation structure and ecological group of tree species in a cerradão forest (Cerrado biome) of Palmas, Tocantins State, Brazil. A forest inventory was performed in an area of 10.15 hectares, using systematic sampling with plots of 400 m2, in which all standing trees, alive and dead, that had diameter at breast height ...

Afghanistan is a very mountainous country. It offers a big variety of ecological conditions, this means a big variety of vegetation types is covering land surface. These vegetation types are consisting of a high biodiversity, since the floristic influence from various neighbour regions is a considerable factor in floristic and vegetation pattern. On the other hand, Afghanistan is a very dry cou...

The rhizosphere effect on bacterial communities associated with three floristic communities (RW, FI, and M sites) which differed for the developmental stages was studied in a high-altitude alpine ecosystem. RW site was an early developmental stage, FI was an intermediate stage, M was a later more matured stage. The N and C contents in the soils confirmed a different developmental stage with a k...

The tropical climate in China exists in southeastern Xizang (Tibet), southwestern to southeastern Yunnan, southwestern Guangxi, southern Guangdon, southern Taiwan, and Hainan, and these southern Chinese areas contain tropical floras. I checked and synonymized native seed plants from these tropical areas in China and recognized 12,844 species of seed plants included in 2,181 genera and 227 famil...
