Annual Water Yield Estimation for Different Land Uses by GIS-Based InVEST Model (Case Study: Mish-khas Catchment, Ilam Province, Iran)

Fresh water supply and its security encounter a high level of fluctuating variability under global climate changes. To address these concerns in catchment water management, a good understanding of land use/cover impacts on the hydrological cycle affecting water supply is crucial. The objective of this study is to define a model to investigate the impact […]

Nitrogen Metabolism, Digestibility and Blood Profile of West African Dwarf Goats Fed Dietary Levels of Cajanus cajan as Supplement to Cassava Peels

The effect of inclusion level on nutrient intake, digestibility, nitrogen metabolism and haematological parameters of West African Dwarf (WAD) goat fed Cajanus cajan as supplement to cassava peels was investigated in a completely randomized design experiment using twenty-four WAD goats with average initial weight of 10.75±0.85kg (March-September, 2016). There were four treatments as: A=100% Cassava […]

Impact of Organic, Inorganic and Superabsorbent Polymer Materials on Soil Properties under Plant Community of Nitraria schoberi in Deserts of Semnan, Iran

Improving water use efficiency and soil properties are two major factors for sustainable development in desert areas. Therefore, this research aims to study the effectiveness of a biological hydrogel, plant vegetation layer, sand and barley straw with rain harvesting techniques through micro-catchment operation on some soil properties including pH, Nitrogen, Electrical conductivity, Sodium Absorption Ratio, […]

Climate Change Impact on Quality of Life Indicators of Pastoralists (Case study: Rangelands of Haraz River Basin, Mazandaran province, Iran)

Climate changes pose great threats to the main services of ecosystems such as food security, water security and health. This research was carried out in Haraz river basin rangelands, Mazandaran province in the north of Iran in 2015-2017 to analyze the perspectives of Haraz river basin (HRB) pastoralists about climate change. From 5236 local pastoralists, […]

Resting Impact on Vegetation Cover of Fescue-Forbs Rangeland in Mongolia

The rangeland in the Khangai mountain region in Mongolia has degraded for the last decades mainly because of overgrazing and climate change. Livestock production is important part of the economy and is based on natural rangeland. In this research we seek to elucidate the influence of five years (2004-2009) of protection from grazing on vegetation […]

Required Growing Degree-Days (GDDs) for each Phenological Stage of Fritillaria imperialis

Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate […]

Responses of Herbaceous Species to Fire in Persian Oak (Quercus brantii) in Coppice Forests

Zagros forests are one of the important natural ecosystems in Iran with high plant diversity and variety of plant communities. In recent decades, fire events have frequently occurred in some of these ecosystems. The purpose of this research is to investigate the composition and diversity of herbaceous species after nine years of fire occurrence in […]

Investigating the Effects of Different Harvesting Intensities on Forage Production in Sahand Rangelands of Eastern Azerbaijan Province, Iran

Due to the decreasing trend of rangelands, many native species are vulnerable and even at risk of extinction. Therefore, seed preservation and propagation of native species of rangelands and recognition of the characteristics of grazing, drought tolerance and their production potential are very beneficial. In this study, the five species of Festuca ovina, Festuca rubra, […]

Determining Timely Entry and Exit of Livestock in Rangelands Using Bromus tomentellus Phenological Stages (Case Study: Goorab Rangeland of Isfahan)

In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus […]
