resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. to observe how differences in forest management affect the genetic structure of fagus orientalis lipsky (oriental beech), we evaluated thirteen beech sites across hyrcanian forests, based on six microsatellite loci. significant di...
Rapid exploratory field survey, to identify indigenous chicken ecotypes was conducted in north Gondar zone of Ethiopia. Chicken ecotypes including Necked neck, Gasgie and Gugut from Quara, Alefa and Tache Armacheho districts were identified, respectively. Morphological variations among the three study populations and nine measurable traits were evaluated. General linear model, canonical discrim...
ackground: knowing the human platelet antigens (hpa) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. hpa genes frequency in iran is not evaluated, so we investigated the hpa-2, hpa-3, and hpa-5 frequency and their polymorphism. materials and methods: dna from 120 iranians (99 iranian blood donors and 21 patien...
In order to identify ecotyps of field binweed (Convolvulus arvensis L.), seeds from eight proviences, including 125 populations were gathered and sent to Weed Research Department of Plant Pests & Diseases Research Institute, Tehran, Iran. These seeds planted in a uniform environment condition in Tehran. On the base of 24 morphological and physiological characteristics of seedling that derived f...
Glutathione S-transferases (GSTs) are a major family of detoxification enzymes which possess a wide range of substrate specificities. Interest in insect GSTs has primarily focused on their role in insecticide resistance. In this study, following World Health Organization (WHO) routine susceptibility test, DNA was extracted from specimens of Anopheles stephensi collected from the Kazeroon distri...
