Mountainous landscapes in Central Zagros are mainly used as grazing rangelands to feed animals and are heavily degraded. Overgrazing may impose a negative effect on rangeland productivity and sustainability through significant changes in soil properties. Soil nitrogen (N) mineralization is one of the key biological processes that might be affected by biotic and abiotic factors including range g...
Context. Long-period variable stars (LPVs) are pulsating red giants, primarily in the asymptotic giant branch phase, and they include both Miras semi-regular variables (SRVs). Their period-age period-luminosity relations enable us to trace different stellar populations, as intrinsically very bright cover a wide range distances ages. Aims. The purpose of this study is establish census LPV region...
