Adverse changes in rangeland vegetation can be considered as one of the criteria for land degradation. Some of these changes can be evaluated through monitoring the spatial changes of landscape parameters. This study aimed to investigate the landscape changes in Kezab rangelands of Yazd province, central Iran. Landsat satellite images of 1990, 2002, and 2013, and landscape metrics including Tot...

introduction ownership is an important element for sustainability development in natural resource management. rangelands vegetations are important factor for produce in traditional herding therefore recognition of different utilization methods and management of this vegetation resource production for animal grazing and rangelands condition is very important. so this research carried out in 2009...

Fish is a unique source of micro-nutrients. However, many parts of larger fish, such as the head and the bones, are discarded during fish processing despite the high levels of nutrients, and particularly micronutrients found in these parts. Thus the promotion and use of fish byproducts to create low-cost, high-quality food could help reduce malnutrition. This practice illustrates the nutritiona...

Rangelands essentially comprise geographical regions dominated by grass with or without scattered woody plants. Rangelands are often considered to function primarily as feed for livestock. In this view, conservation and biodiversity issues are secondary. The alternate view involves recognising rangelands as a biome without a specific function, but where there is an implied responsibility for in...

Corn milling byproducts are expected to increase dramatically in supply. Two primary types of milling processes currently exist, resulting in quite different feed products. The dry milling process produces distillers grains plus solubles, and the wet milling process produces corn gluten feed. These feeds can be marketed as wet feed, or they can be dried and marketed as either dry corn gluten fe...

Field production of ornamental shrubs often coniferous species, respectively, were monitored for 12 results in significant topsoil removal and degradation of weeks in pot culture in both composite tailings (CTs) and surface soil physical properties. Building soil organic matter tailings sand (TS) materials obtained from the oil sands through compost amendments is one way to ameliorate plant, Sy...

Rangelands provide the main forage resource for livestock in many parts of the world, but maintaining long-term productivity and providing sufficient income for the rancher remains a challenge. One key issue is to maintain the rangeland in conditions where the rancher has the greatest possibility to adapt his/her management choices to a highly fluctuating and uncertain environment. In this stud...
