Evaluation Of Genetic Diversity Between Some Nitraria Retusa Populations Using Molecular Markers, Z. Abo El-Kheir, M. El-Monayeri, D. Abd El-Raof
Al-Azhar Bulletin of Science
Nitraria retusa (Nitrariaceae) is a true xerophyte plant grows in most deserts of Egypt, especially in wadies habitat and dry salt marshes. This study aims to evaluate any possible genetic diversity among samples of Nitraria retusa grown under different habitats using Random Amplified Polymorphic DNA (RAPD) markers, protein electrophoresis and isozyme electrophoresis. For such goal, the ecological aspects of the selected habitats were investigated with the view of finding correlations among these markers and some ecological parameters. Five collected samples of Nitraria retusa were collected from Wadi Hof (sunny and shady), Oyun Musa, Kattamyia and Hammam Faraon. The obtained results …

Ecophysiological Studies On Some Species Growing Along Wadi El-Natrun El-Alamein Desert Road, Safaa Ismaeil, Zeinab Khidr, Aesha Abd El-Kawy
Al-Azhar Bulletin of Science
The present study was carried out to elucidate the adaptive responses of some desert plants growing in two different habitats along Wadi El-Natrun El-Alamein Desert Road. The species characterizing the sand- gravel plain habitat include Thymelaea hirsuta, Artemisia monosperma, Deverra tortuosa and Traganum nudatum, while those characterizing the dry saline habitat are Zygophyllum album and Asphodelus microcarpus. The species of dry saline habitat attained higher values of water content, degree of succulence, calcium, magnesium and chlorides. Also, Zygophyllum album achieved the highest ash content and this was mainly due to accumulation of Na+, Ca+2 and Mg+2. In addition, Na+ were …
Preliminary Survey Of Terrestrial Vertebrate Fauna And People’S Awareness Towards Wildlife In The Northern Governorate Of The Gaza Strip, Maged Yassin, Abdel Fattah Abd Rabou, Mohammad Al-Agha
Preliminary Survey Of Terrestrial Vertebrate Fauna And People’S Awareness Towards Wildlife In The Northern Governorate Of The Gaza Strip, Maged Yassin, Abdel Fattah Abd Rabou, Mohammad Al-Agha
Al-Azhar Bulletin of Science
Many plant and animal species have disappeared in the Gaza Strip during the last 5-6 decades. No effort has been made to stop such disappearance and/or to conserve the biodiversity. This survey deals with the terrestrial vertebrate fauna in the Northern Governorate of the Gaza Strip. The ecological awareness of people (n=75) towards wildlife was investigated using a questionnaire specially designed for this purpose. A total number of 119 terrestrial, wild vertebrate species (13 mammals, 86 birds and 20 reptiles), in addition to many localy extinct mammalian species were recorded. Many wildlife species are on their way to extinction where …
Survey And Population Studies On Coleopterous Fauna Of Northern Sinai And Beni–Suif Governorates Using Light Traps, G. Morsi, A. El–Gharbawy
Survey And Population Studies On Coleopterous Fauna Of Northern Sinai And Beni–Suif Governorates Using Light Traps, G. Morsi, A. El–Gharbawy
Al-Azhar Bulletin of Science
A survey together with studies on population densities and relative abundance of coleopterous species were conducted by the use of light traps at Al–Arish city, North Sinai and Sids Agricultural Research Station, Beba City, Beni Suif during 2005. At Beni–Suif the survey revealed the presence of 45 coleopterous species belonging to 31 genera of 9 families: Anobiidae, Bostrychidae, Carabidae, Cicindelidae, Dytiscidae, Elateridae, Hydrophilidae, Scarabaeidae and Staphylinidae. While surveying Northern–Sinai revealed the presence of 64 coleopterous species belong to 44 genera of 10 families: Anobiidae, Bostrychidae, Carabidae, Cerambycidae, Dytiscidae, Elateridae, Hydrophilidae, Paussidae, Scarabaeidae and Staphylinidae. The total annual number of beetles …
