Volume 69, Issue 3 , December 2016, , Pages 691-698


  For the scientific and accurate management of rangeland ecosystems, having information about ecosystem as indicators of ecosystem health and function is needed. The aim of this research is to study the effects of grazing on soil surface indicators and rangeland functional properties by using Landscape ...  Read More

Secondary Compounds as Indicator of Plant Palatability (Case Study: Karsanak Rangelands of Chaharmahal-Va-Bakhtiari Province)

Ataolah Ebrahimi; valiollah Raufirad; Hosein Arzani; Zahra Shojaei Asadeiye

Volume 69, Issue 2 , July 2016, , Pages 297-309


  Determination of rangeland species palatability has some functions such as defining the rangeland grazing capacity and plant composition estimation. Despite the importance of palatability in rangeland management, no appropriate palatability indicator has been defined yet. Therefore, developing an accurate, ...  Read More

Volume 69, Issue 2 , July 2016, , Pages 427-436


  Global warming and climate change have drawn special attention to soil and its potential for stable carbon sequestration. Soils are the largest stores of carbon in terrestrial carbon cycle and contain about three times more carbon than vegetation cover and two times more than that of atmosphere. Studying ...  Read More

Vegetation Changes Procedure Inside and Outside of Exclosure in Tanglaybid Rangelands of Yazd Province (2000-2005)

AliB. Mirgalili; MohammadR. Fazelpoor; fariba zakizadeh
