Questions : While globalisation favours intensive yield-maximizing agriculture with cropping practices that entail agrobiodiversity loss, extensive production systems still exist in areas of marginal lands such as mountainous regions or islands. It is overdue to study systems, their sustainability and ecology potential models for decentralized environmentally balanced land-use. For purpose, we ...

distribution and abundance of plants has been correlated with a variety of complex environmental gradients. environmental factors affect plants growth and need to be understood by ecosystem managers. this study was carried out to examine the relationships between site factors and different vascular and non-vascular plants in north of iran. for this purpose, vegetation and soil sampling was perf...

miankaleh biosphere reserve it has a set of marine and land ecosystems an area about 67349 ha and is located in the north of iran and southeast farthermost of caspian sea. the diversity of the natural characteristics of caspian region is the cause of diversity in the habitats, and has resulted in nesting of most plant species in the germinative range. regarding the importance of coastal ecosyst...

The present work is a phytosociological synthesis and syntaxonomic overview of the vegetation highest subnival parts (superpuna) open alpine high plateaus (puna) Andes Moquegua, South West Peru, as related to main environmental gradients. Using TWINSPAN DCA ordination analysis, 153 relevés were analyzed. For each association, subassociation community, syntaxonomy, floristic diversity relation w...

Question : Rich fens of the Sphagno warnstorfii-Tomentypnion nitentis alliance require a specific combination base richness and climate to occur. Their rarity at southeastern margins their European range has previously prevented rigorous vegetation classification. We asked how many associations may be delimited here whether some them are restricted high Balkan Mountains showing endemicity. Stud...
