In current work we study epiphytic algae on Hydrilla verticillata in Tigris River within Al-Dora region of Baghdad city during the period between March and December 2013. Total of (128 species, 39 genera) of epiphytic algae on H.verticillata were identified during study. Bacillariophyceae (Diatoms) was dominting group (97species,24genera,80%) followed by Chlorophyceae (18 species,9 genera 11%) and Cyanophyceae (13 species,6 genera,9%).An impressive and temporal distributions of epiphytic algae on H.verticillata was observed in this study. The higher total number of epiphytic algae (523.3×104individual/g WW) was recorded in summer 2013, while the lower was (194.9×104individual/g WW) in winter 2013.Three biodiversity indices (Shannon- Weaver, richness, and evenness) were calculated. And different indces values were evaluated in seasons.

In this research a low cost material (Citrus aurantifolia) was used as adsorbent for removing of organic matter expressed as biological oxygen demand (BOD) from domestic wastewater. Batch experiments were used in this study under certain experimental conditions. The results showed that the maximum value of adsorption capacity of Citrus aurantifolia with BOD (13.5) mg/g. The maximum removal efficiency of BOD was (69.75%) at higher mass of adsorbent (5gm). The coefficient of determination values were higher for Freundlich than for Langmuir. Freundlich isotherm is better fitting isotherm for the experimental data with a correlation coefficient of 0.8806. The results demonstrated that the best contact time was (105 min.) and removal efficiency increases as contact time increase. The results revealed that the removal efficiency of BOD from wastewater increases when the amount of adsorbent increase.

In this study the Check list lizards of Iraq were investigated. by reviewing the old and new data as well as carrying out field work and study of material in the Natural history Museum of Iraq as well as many departments and colleges in various universities, are discussed.Further, various relevant websites in the Internet specialized lizards. I found in this study 7 families, 27 genera and 50 species distribution in the different parts of Iraq. During this study I found Asaccussaffinae (Afrasiab&Mohamad, 2009) the first time in SheraSwar Cave in the Saffine Mountain near Erbil, Kurdistan and the first record new species in Iraq and foundPtyodactyluspuiseuxi (Boutan, 1893) the first time in same area . Also foundCarinatogeckoheteropholis(Minton, S. Anderson, and J. A. Anderson, 1970) Which is one of the endemic species in western Iran in the Erbilwestern Zagros foothills in Erbil.Trapelusruderatus (Olivier, 1804) found in the central of Iraq. Cyrtopodionscaber (Heyden, 1827) Previously found in southern Iraq But recently also recorded in the center and northern Iraq.Varanusnesterovi (Bohme, Ehrlich, Milto, Orlov&Scholz, 2015) new species in the northern of Iraq. Lacerta media (Lantz &Cyren, 1758) found newly in central and northern of Iraq and Timonkurdistanicus,Apathyacappadocica (Werner, 1902) (Suchow, 1936) northern of Iraq. I note the two families were finding Previously in Iraq and they did not record any new genus and species in Iraq.
