The extinction of some of medical plants is not only due to the overuse of them and the grazing pressure but also their incorrect exploitation methods. Ferula assafoetida is one of the most important medical plants in Iranian rangelands, which is gradually disappeared from its habitats due to destructive traditional exploitations. Therefore, in order to […]
Rangeland degradation is one of the global concerns affecting the pastoralists and those who suffer from its negative environmental consequences. Grazing exclosure has been extensively used among the techniques implemented by the government to protect the fertility of threatened rangelands. The impact of exclosure has been a controversial issue; therefore, it is important to understand […]
This book consists of 14 chapters covering important aspects in regards to various terrestrial ecosystems, wetlands, river systems, mine site rehabilitation, marsh ecology and heavy metals pollution. Also aims to fill some of the information gaps in ecological restoration, particularly in under-researched ecosystems around the world. Restoration ecology emerged as a separate field in ecology […]
Dr. Abbasali Sanadgol is an associate professor in rangelands and forests research institute, IRAN, He is retired now. He earned his undergraduate and master degrees in natural resources and range management in 1976 and 1992 respectively from natural resources faculty of Tehran University and worked as a natural resources and range management researcher for 29 […]
Rangelands are the most important ecosystem for carbon sequestration. Knowledge of plant response to grazing is one of important requirements for rangeland management. Stocking rate is one of main factors in destruction of the vegetation cover in rangeland ecosystems. Livestock grazing has the potential to substantially alter carbon storage in grassland ecosystem. This study examined […]
Rangeland ecosystems provide a wide range of services such as gas regulation function whose economic value has not been understood. The present study aimed to estimate the economic value of CO2 absorption and oxygen generation services using unit price in Sheikh Musa Rangeland, Mazandaran Province, Iran. In the study area, clipping and weight and photosynthesis […]
Not all of the Sudan has been covered by post studies; and parts of it seemed more favoured research topic of the others. The first attempt to study the flora of the study area was in 1958, which included in the work of Harrison and Jackson about classification of the Sudan vegetation. The study area […]
It is widely agreed the Anthropocene has seen an unprecedented decline in the natural resources conditions that have underpinned the economic growth of the last few hundred years. As communities, we have not responded to Boulding’s vision of ‘the coming space ship earth’ although not for want of much official and private effort. As ‘wicked […]
He received his B.Sc. degree in Biology (1990) from Department of Biology, University of British Columbia, Canada, also M.Sc. in Botany (1993) from Department of Botany, University of British Columbia, Canada and Ph.D. in Plant Ecology (1996) from Department of Animal & Plant Sciences, University of Sheffield, England. Dr. Fraser’s expertise is in grassland and […]
Annual Sainfoin (Onobrychis crista-galli (L.) Lam.) is widely adapted to moderate and cold regions of Iran and naturally grows in pasture and rangelands used for forage in these areas. In order to study the effects of priming on seed germination and seedling growth in O. crista-galli, two factorial experiments were conducted based on a randomized […]
