Factors affecting the downturn of traditional livestock husbandry in local communities of northwestern rangelands of Iran
Abstract Currently, a combination of natural and human factors has led to the lack of cost-effective production, resulting in the downturn of traditional animal husbandry (DTLH) in rural regions. This research aims to investigate the factors contributing to the DTLH in indigenous communities in…

An efficient estimation of crop performance in sheep fescue (Festuca ovina L.) using artificial neural network and regression models
Abstract Festuca ovina L. (sheep fescue), a perennial grass plant found in mountainous regions, is important from both an ecological and economic viewpoint. However, the variability of biological yield of sheep fescue due to its reliance on different characteristics makes it difficult to accurately…

Determining changes in carbon sequestration and some soil properties in the elevation gradient of rangelands in the north of Sablan, Iran
Introduction Rangeland ecosystems cover more than half of the earth's land surface, these ecosystems have high carbon sequestration and cause the formation of about 10% of the total biomass carbon reserves and 30% of soil carbon. Carbon sequestration potential differs according to plant species…
