Plant Species and Functional Types’ Diversity in Relation to Grazing in Arid and Semi-arid Rangelands, Khabr National Park, Iran
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
متن کاملThe effect of waterway distance on species diversity and Plant Functional Groups in mountainous rangelands of Anbaran Chai, Ardabil
The plant communities locating at the margins of the waterways play a vital role in the ecological processes and ecosystem services in the semi-arid mountainous regions. In this study, variations of plant diversity and composition at different distances from the waterway and its slope aspects were investigated. For this purpose, 15 sub-basins with a variety of area and length of waterway, in bo...
متن کاملCovariation in Plant Functional Traits and Soil Fertility within Two Species-Rich Forests
The distribution of plant species along environmental gradients is expected to be predictable based on organismal function. Plant functional trait research has shown that trait values generally vary predictably along broad-scale climatic and soil gradients. This work has also demonstrated that at any one point along these gradients there is a large amount of interspecific trait variation. The p...
متن کاملبررسی تاثیر چرای دام بر گروه های عملکردی گیاهان در منطقه بهارکیش قوچان (plant functional types)
چرای دامهای اهلی و خشکسالی در ایران، به عنوان مهمترین عوامل در تغییر و شکلگیری پوشش گیاهی مطرح هستند. عوامل زیستی و غیر زیستی باعث تغییرات قابل پیشبینی در صفات گیاهی در پیش- (plant functional types (pfts)) امتداد گرادیان محیطی میشوند. گروههای عملکردی گیاهی بینی تغییرات در فرایندهای اکوسیستم را مستقیماً از طریق تغییرات منعکس شده در ترکیب گونههای گیاهی در پاسخ به تغییرات محیطی امکانپذیر میکند....
15 صفحه اولthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
