Ammodendron persicum (Bunge & Boiss.)is a desert shrub specie which grows on some sand dunes and sandy areas of South Khorasan and Sistan-va-Baluchestan provinces in east of Iran. Low distribution and narrow ecological range have put this species under threat. In order to evaluate the possibility of long-term preservation of A. persicum seeds in cryogenic […]
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 […]
Mountain ranges cover around one-half of Iran, and Zagros ecosystem is considered as one of an important biological site in Iran. Physiographic factors such as altitude and aspect have an important role in plant species distribution. This study was conducted in the Nawa mountain ecosystem in the western side of Zagros ranges, located in the […]
Rangelands cover approximately 85% of Kenya’s land mass and is a major resource for livestock farming with a considerable potential to mitigate climate change, yet these lands are stressed differently by various management. Our study aimed at determining the influence of grazing management systems (rotational, continuous and ungrazed) on soil organic carbon stocks in Yoani […]
The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral […]
Degradation of plant patches is considered as one of the indices for rangeland degrading health condition. Investigating the accuracy of triple indices (infiltration, stability and soil nutrient cycle) presented by LFA method seems necessary to determine its efficiency in semi-arid areas with the least cost. This study aims to investigate the role of vegetative species […]
Persian juniper and Pistachio are grown in low density in the rangelands of North-East of Iran. These rangelands are populated by evergreen conifers, which are widespread and present at low-density and sparse shrub of pistachio in Iran, that are not only environmentally but also genetically essential as seed sources for pistachio improvement in orchards. Rangelands […]
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 […]
