Rangeland biodiversity is a multidimensional spectacle that includes the diversity of organisms, genetic differences among them and the communities, ecosystems, and landscape patterns. The variety of biodiversity life and processes is essential for moral, aesthetic and economic reasons. This review aimed to combine the earlier works on rangeland biodiversity: status, challenges and opportunities. Despite being […]
Aboveground Net Primary Production (ANPP) is one of the most important characteristics of rangeland ecosystems that is involved in important issues such as carbon balance. The aim of this study was to model the ANPP of Plant Functional Types (PFTs) and total ANPP with topographic factors in Siahpoush and Ganjgah rangelands of Ardabil province, Iran. […]
One of the major challenges in semi-arid regions of Iran is to supply the adequate forage for livestock and meanwhile prevent the destruction of rangelands due to overgrazing. Therefore, this study aimed to compare three cropping systems of barley using Salsola turcomanica (ST), and Chrysopogon zizanioides (CZ) in three treatments of barley+ST, barley+ST+CZ and mono-culture […]
This study investigated the effect of grazing on plant community structure. Two adjacent areas: one grazed for five years and non-grazed were sampled in March-April 2020. On each area, three sampling sites were selected. Quadrats of 1×1m were placed at 5m intervals along 50m transects (198~ 40 transects in total). Plants were identified and percentage […]
