in recent years, rangelands have been regarded as potential carbon sinks. one of the most widely suggested options to sequester more c in rangelands is the restoration of the degraded rangelands through grazing the exclusion. in present study, the effects of exclusion on the carbon sequestration of gomishan rangelands were investigated. three transects were established in a key area inside and ...

due to the lack of specified linage and parentage information from exotic broodstocks of litopenaeus vannamei shrimp, in iran and multiple breeding of closed broodstock populations, also concern about the low level of genetic diversity and accumulated inbreeding and in order to comparison of the genetic variability indices and analysis of the genetic differentiation, total of 30 samples from bo...

common carp ( cyprinus carpio ) population has been declined in the caspian sea in the recent years, mainly due to human manipulation. this valuable species needs to be protected in the caspian sea. considering the commercial value of common carp, its rehabilitation program has been established. in the present study, 8 microsatellite loci were used to assess genetic variation and population str...
