In this study, by examining the character of the morphometric and meristic in which Cyprinion macrostomus samples obtained from different locality in Tigris, morphometric character which are transformed subject to discriminant analysis and depending on grouping model to number of discriminant functions and according to importance of these totally variance, morphogical variance among populations...

       The study included seven common types of fish in the Iraqi local market Salah al-Din Governorate / Tikrit, which are (Carasobarbus luteus, Alburnus mossulensis, Cyprinion kais, Chondrostoma regium, Barbus barbulus, belayewi, subquincunciatus). The cholesterol and triglycerides these showed that levels experimental were (104.55-9.56 -6.37-9.56 -14.88-51.03-15...

Sexual selection is considered a potent evolutionary force in all sexually reproducing organisms, but direct tests in terms of experimental evolution of sexual traits are still lacking for simultaneously hermaphroditic animals. Here, we tested how evolution under enforced monogamy affected a suite of reproductive traits (including testis area, sex allocation, genital morphology, sperm morpholog...

To study the several elements and causes of ageing, diverse model organisms and methodologies are required. The most frequently used models are Saccharomyces cerevisiae, Caenorhabditis elegans, Drosophila melanogaster and rodents. All have their advantages and disadvantages and allow studying particular aspects of the ageing process. During the last few years, several ageing studies focussed on...
