Esox lucius is an economically important freshwater species. Mitochondrial cytb, 12SrRNA, and 16SrRNA gene sequences were used in order to clarify the genetic variation and population structure in three E. Lucius populations, i.e., one Wild population (W) and two hatchery populations (Hatchery Population I-HPI and Hatchery Population II-HPII). A total of 55 individuals, with 19 from wild and 1...

Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-201...
Alburnoides nicolausi is one of the freshwater, benthopelagic species with high ecological importance. This fish is native to Iran and found in the basin Tigris. Considering the lack of information on population genetics of A. nicolausi, the genetic diversity and structure of this valuable species was studied in the present research. For this, A. nicolausi samples were collected from Joushan an...
Abstract Intraspecific genetic diversity is a key aspect of biodiversity. Quaternary climatic change and glaciation influenced intraspecific by promoting range shifts population size change. However, the extent to which affected on global scale not well established. Here we quantify nucleotide diversity, common metric in more than 38,000 plant animal species using georeferenced DNA sequences fr...
Population genetic diversity is widely accepted as important to the conservation and management of wildlife. However, habitat features may differentially affect evolutionary processes that facilitate population genetic diversity among sympatric species. We measured genetic diversity for two pond-breeding amphibian species (Dwarf salamanders, Eurycea quadridigitata; and Southern Leopard frogs, L...
