Since real data is time-consuming and expensive to collect, label, and use, researchers have proposed approaches using synthetic variations for the tasks of signature verification, speaker authentication, handwriting recognition, keyword spotting, etc. However, the limitation of real data is particularly critical in the field of writer identification in that in forensics, enemies or criminals u...
Range suitability and its grazing capability are the most important criteria in rangeland analysis and monitoring. Determination and monitoring of factors affecting on range suitability and diagnosis of them are important .All range ecosystem components affect range suitability. Which among them physical and vegetational factors, forage production, water resources and sensitivity to erosion wer...
Considering the poor condition of most rangelands of Iran, evaluation of rangeland potential and determination of suitability for continuous and optimal utilization seems necessary. The purpose of this study was to investigate the rangeland suitability for sheep and goat grazing using FAO and GIS methods. Therefore, three criteria including vegetation cover, water, and soil were studied. The ...
Rangeland management is one of the basic items in ecosystem management and its purpose is the optimal use of rangelands in order to achieve the desired yield and maintain the stability of rangeland ecosystems. Rangelands play an infrastructural role in the countrychr('39')s economy and pave the way for achieving the goals of sustainable development. However, due to the importance of these resou...
Across its entire range in Australia’s western and southern rangelands, Australian sandalwood (Santalum spicatum [R.Br.] A.DC.) is on a path towards ‘extinction the wild’––the International Union for Conservation of Nature’s penultimate category conservation risk. Sandalwood populations have substantially diminished or become locally extinct, predominantly consequence land clearing agriculture,...
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...
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...
