Abstract Illegal hunting of ungulates can reduce the prey base carnivores, which increase human–carnivore conflict ( HCC ) through livestock depredation. However, relationship between ungulate poaching, wild abundance and depredation has rarely been empirically studied. We surveyed 18 sites across Hyrcanian forest in northern Iran; a global biodiversity hotspot under pressure from illegal ungulates, depletion, grazing . conducted three field surveys 1,204 km 93 4 × cells to count signs...
Mercury (Hg) is one of the main global pollutants that may biomagnify in food nets, especially wetlands. Birds be useful biomonitoring Hg such habitats and even serve vivo samples. This paper examined concentration feathers seven bird species foraging on Fereydunkenar International wetland (in 2013). Mean concentrations found ranged from 0.005 ± 0.002 μg g-1 d.w. (dry weight) (Common hoopoe) to 0.38 0.047 (Greylag goose). Significant differences were noted between as well trophic levels...
Miankaleh and Gomishan International Wetlands are important wintering areas for waterbirds in the Caspian Sea region. Previous studies revealed increased exposure to metals some species of using these wetlands. In this study, we examined concentrations cadmium (Cd), chromium (Cr), iron (Fe), lead (Pb), zinc (Zn) kidneys, liver, pectoral muscle Gadwall (Anas strepera) Common Teal crecca) collected 2012. addition, measured elements water sediments from collection sites. The genders differed...
In order to investigate bioaccumulation of mercury in Iranian coastal waters fish, tiger tooth croaker (Otolithes ruber) and yellowspotted trevally (Carangoides fulvoguttatus) from the Gulf Oman grass carp (Ctenopharyngodon idella) silver (Hypophthalmichthys molitrix) Zabol Chahnimeh reservoirs were sampled May 2012. these ecosystems, total concentrations measured muscle gill four fish species. Both regions did not reveal a significant difference. H. molitrix O. ruber, increased with...
A three year study of the seasonal changes in biodiversity and density waterfowl wader were carried out Sorkhrud International Wetland which is a part Feridonkenar's intentional wetlands (registered Ramsar Convention). Birds counted through total count method. The included 119592, 140901 139160 waders winter 2007, 2008 2009 respectively. average species this wetland varied from 64 to 76 birds ha. In all mentioned years, maximum started with continued by one month period Common Teal (Anas...
Abstract Interactions between law enforcement agents in conservation (e.g., rangers) and illegal resource users hunters) can be violent sometimes fatal, which negatively affects efforts people's well‐being. Models from social psychology, such as integrated threat theory (ITT) (intergroup interactions shape intergroup emotions, prejudices perceived threats leading to hostile attitudes or behaviors groups), are useful addressing interactions. Conservation approaches relying mainly on have...
The Great Gerbil, Rhombomys opimus, is widely distributed in degraded and fragmented desert semi-desert habitats of the Iranian Plateau. Recent habitat fragmentation from overgrazing by livestock a government-sponsored rodent control programme threaten to isolate populations increase their susceptibility inbreeding loss genetic diversity. We examined data Gerbil region where they are deficient understand how distance, geography, anthropogenic factors influence population structure diversity...
Assisted phytoremediation technique is greatly progressed, but still in development and needs further study.Thereby, this study, Ligustrum texanum (Wax-leaf Privet) was exposed to soil treated with the various concentrations of lead nitrate (Pb(NO3) 2 ) (0, 100, 300, 500, 700 mg L -1 humic acid (HA) (0 300 irrigation solution for three-month period, order evaluate species' ability Pb 2+ ; effect HA on process.Un-planted pots were also used investigate direct role plants remediation.The plant...
Assisted phytoremediation is extremely promising, but still in development and needs further study. Therefore, the combination use of Erythrostemon gilliesii humic acid was studied to aid efficiency lead nitrate Pb(NO3)2 phytoextraction. Seedlings were exposed five simultaneous treatments (0, 100, 300, 500, 700 mg L−1) (0 300 for three growth months (90 days summer) their effects on physiological morphological traits plants recorded. Up L−1, Pb showed apparent positive (stimulative) plant...
