Little is known about genetic variation of seed related traits and their association with forage characters in sainfoin. In order to investigate the variation and relationship among seed yield and its components, 93 genotypes from 21 wild and cultivated species of genus Onobrychis were evaluated using a randomized complete block design with four replications at Isfahan University of Technology ...
inappropriate waste management is considered as an important factor for attracting wild animals to the inhabited area. this leads to food conditioning in some wild species, which changes their feeding behavior and food habits. usually this trend reduces the fear of wild species and leads to conflict between wild species and human. we sampled five landfill sites of villages and small towns in wh...
the majority members of the family coccinellidae are predators, so they have received considerable research attention because of their potential to act as biocontrol agents. the coccinellids complex of pistachio trees was monitored at both cultivated and wild pistachio plantations in shahr-e babak (kerman, iran) during 2009 - 2010. sampling was carried out randomly in the cultivated pistachio p...
Background: Crop wild relatives are wild species that are closely related to crops. They are valuable as potential gene donors for crop improvement and may help to ensure food security for the future. However, they are becoming increasingly threatened in the wild and are inadequately conserved, both in situ and ex situ. Information about the conservation status and utilisation potential of crop...
Knowledge of species’ habitat needs is considered as one of the requirements of wildlife management. We studied seasonal habitat suitability and habitat associations of wild goat (Capra aegagrus) in Kolah-Qazi National Park, one of its typical habitats in central Asia, using Maximum Entropy approach. The study area was confined to mountainous areas as the potential habitat of the wild goat. Ele...
Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...
wild boar is distributed throughout iran except highly arid areas. in recent years, however, population size of wild boar has increased primarily because of reduction in population size of natural predators such as leopard. conversely, changes in land-use practices and increase in foraging of livestock in natural habitats has led to reduction of food resources and consequently, has forced the s...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
In order to explore biodiversity of Fusarium species associated with the inflorescences of poaceous weeds, heads and inflorescences were collected from wild grasses in Ardabil province (Iran). Fusarium species were isolated using general and selective media. Pure cultures were established using a single spore technique. The isolates were identified based on morphological and molecular data. Seq...
Hybridization has played a central role in the evolutionary history of domesticated plants. Notably, several breeding programs relying on gene introgression from the wild compartment have been performed in fruit tree species within the genus Prunus but few studies investigated spontaneous gene flow among wild and domesticated Prunus species. Consequently, a comprehensive understanding of geneti...
