Trophic interactions among three elasmobranch species coexisting in the Oman Sea: implications for resource partitioning
In this study, trophic interactions were studied among three elasmobranches including Iago omanensis, Rhinobatos punctifer and Torpedo sinuspersici coexisting in the depth ranging from 50 to 100 meters in the Oman Sea (Sistan and Balochistan waters). A total of 238 specimens were collected using industrial bottom trawlers of ‘FERDOWS’ during spring and summer,2014 and their stomach contents wer...
متن کاملHybridization among Three Native North American Canis Species in a Region of Natural Sympatry
BACKGROUND Population densities of many species throughout the world are changing due to direct persecution as well as anthropogenic habitat modification. These changes may induce or increase the frequency of hybridization among taxa. If extensive, hybridization can threaten the genetic integrity or survival of endangered species. Three native species of the genus Canis, coyote (C. latrans), Me...

15 صفحه اولGenetic Relationships among Three Yarrow Species Based on Phenotypic Traits and Peroxidase Profiling
Fifteen yarrow populations from different species Achillea millefolium L., A. biebersteinii L. and A. nobilis, from different geographical areas of Iran were studied using 24 morphological traits and peroxidase profiles. Comparison of mean values of different phenotypic traits show A. millefolium and A. biebersteinii L. had higher plant height and crown diameter; however, A. nobilis had higher ...
متن کاملRelationships Among Forage and Litter Production in Three Grazing Intensities in Nodooshan Rangeland (Yazd, Iran)
Grazing management plays an important role in the continuous and economicutilization of pastures. Proper grazing management is a main factor for the accumulation ofplant litter which reduces soil erosion and increase the soil permeability to keep moremoisture in the soil. In current study, the effect of three different grazing intensities (low,moderate and high) along with the grazing gradient ...
