Background: A field study on the transfer of primordial radionuclides 238U, 232Th, 40K and fallout radionuclides 210Po in different plant species in tropical forest of western Ghats environment is presented. Material and Methods: The Top storey, Second storey, Shrubs and epiphytic plant species were chosen and concentration of these radionuclides in plant and soil were measured by employing gam...

The cultivation of wild-harvested plant species is one strategy to achieve conservation while meeting continued demand. A limitation this approach for used in Traditional Chinese Medicine, however, that products produced under ex situ artificial agricultural conditions are often not a perfect replacement their wild-collected counterparts, so demand materials persists. This situation applies Ame...

The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...

jajrood protected complex (khojir and sorkheh hesar national parks and jajrood protected area) is one of the most important habitats of central alborz wild sheep (ovis gmelini x o. vignei) in iran. since the species mate in fall, then fall home range has critical rule in life cycle of this species. using the ecological niche factor analysis (enfa), effective factors on the presence of species w...

kolah ghazi national park is one of the most important habitats for wild goat in iran with a population of around 2000 heads. in order to model the habitat for this species, a presence only layer was used as input to enfa method in biomapper software. ecogeographic factors were also used as independent variables including plant community, distribution of predators, geomorphologic features, main...

Ducrosia anethifolia (DC.) Boiss. is belongs to the Apiaceae family. It is one of the three species of Iranian Ducrosia Boiss. species growing wild in several areas of the country. In this research, we extracted the essential oil and it analyzed by GC/MS. The analysis of essential oil from leaves of D. anethifolia about 19 constituents was identifed and percentage composition was determined (94...
