ABSTRACT The geological and tectonic background of the Sabalan area in NW Iran its present-day surface processes make it ideal for examining effects shaping Earth's crust. As a result intense distribution pre-Quaternary Quaternary structures (e.g., faults, joints folds), most drainage basins southern central parts study have developed under tectonic-dominated conditions, whereas erosional are g...
The present study was carried out to assess and document ethnobotanical knowledge of the plants of Sabalan district in Ardabil Province, as the area has diverse flora and high ethnobotanical potential. Medicinal plants of Sabalan were studied through collections of plant specimens and by interviewing local informants from several villages. For Each plant species the scientific and vernacular na...
Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions other factors such as oligotrophication, eutrophication, microbial activities. In addition, hydrological variability can cause greater differences residence time cycling man-made (reservoirs) than natural lakes. Thus, investigations are needed on vertical mixing new impounded reservo...
In this study, we obtained two-dimensional tomography maps of the Rayleigh wave group velocity for the northwest part of the Iranian Plateau in order to investigate the structure of the crust and the uppermost mantle of NW Iran. To do this, the local earthquake data during the period 2006-2013, recorded by the 10 broadband stations of the Iranian seismic network (INSN) were used. After the prel...
BACKGROUND The aims of this study were to examine the prevalence of trichomoniasis among women aged 18 to 48 yr in Ardabil, northwestern Iran and the relationship between demographic factors and the risk of infection. METHODS Vaginal discharge samples of 914 women aged 18 to 48 yr, referred to Gynecology Clinic of Sabalan Hospital of Ardabil, Iran in 2014, were collected and Trichomonas vagin...
The aim of this study was to investigate the flora, life form, chrotype, diversity and evenness of accompanying species of Artemisia melanolepis Boiss. and Artemisia aucheri Boiss. in the south east of Sabalan. Species were collected and identified. Overall, 82 identified plant species was belonging to 23 families and 61 genera. Asteraceae, Fabaceae, Lamiaceae and Poaceae families were the domi...
Grazing intensity should follow the management roles to prevent the soil compaction. Soil compaction decreases plant root penetration so that at 2 MPa the root extension and above ground biomass will stop. In this research, digital penetrometer was used to assessment the soil compaction level in Sabalan region in Ardabil province caused by livestock. Grazing intensity and distance from villa...
Today, due to industrial advances and the expansion of urban environments, it is essential to create ecoparks as places that can provide natural environments for human. The current study performed a comparative ecopark site selection across Ardabil, Meshkinshahr, Sarein, Nir and Namin, using multi-criteria analysis models. To achieve the research objective, four criteria and 15 sub-criteria wer...
