A gravel horizon is preserved in several locations within the world-wide known archaeological site in Saqqara (northern Egypt). It is characterized by a variable thickness, composed of coarse, quartz, quartzitic and flint pebbles, and considered to correspond to gravels of the Edfu Formation, deposited in the Early Pleistocene by the early phase of the Nile development (Protonile Phase). This relatively short (ca. 200 ka) and at the same time very dynamic period of Protonile activity during the Edfu Pluvial is one of the most poorly recognized hydrological-climatic episodes of the Quaternary in north-eastern Africa. This paper is focused on the preliminary sedimentological-petrographic characteristics of these deposits and an attempt to indicate their source areas as well as mechanisms of transportation and deposition in the context of Pleistocene pluvial episodes.

The diversity of solitary bees varies depending on the vegetation, nesting habitats, and nesting fragmentation. The agriculture development in the Suez Canal region is receiving a great deal of attention in Egypt, thus, the diversity of solitary bees are essential for high quality production of seeds, vegetables, and fruit. The objective of this study was to evaluate the biodiversity of solitary bee populations around the Canal region. About 900 - 1000 specimens of bees were collected from different locations of the Ismailia, Suez, and Sinai Governorates. Fifty-five species of bees were identified. With the exception of Melittidae family, all the bee families were present in the Canal region. The total number of species for each family were 7, 9, 11, 13, and 15 species for Andrenidae, Colletidae, Apidae, Halictidae, and Megachilidae, respectively. Lasioglossum mandibularie (Morawitz, 1866) is a newly recorded species collected from Egypt. In the Suez Canal region, the most abundant species found with large populations were Andrena ovatula ssp. ovatula (Kirby, 1802), Ceratina tarsata Morawitz, 1872, and Colletes lacunatus Dours, 1872.

The study presents the results of a field investigation of the crocodile nesting sites on Lake Nasser, observed during the breeding season 2009-2010. A relatively low number of nesting sites was found, explained by the intensity of anthropogenic activity in the area and by the low water levels of Lake Nasser. Based on analysis of satellite imaging and its correlation with the biotope data of the lake shores, a classification system of habitats and of their suitability for crocodile nesting was established. Correlated with land use information, the results can lead to the identification of potential nesting sites for the Nile crocodile, establishing a legal protection system for such habitats.

Efficacy of the Selected Herbicides in Controlling Weeds and Their Side Effects on Peanut

The field experiments were carried out at Ismailia Agricultural Research Station, Agriculture Research Center (ARC) during 2004 and 2005 seasons, to study the effect of the selected herbicides (pendimethalin, oxyflurofen, fluazifop-p-butyl and clethodim) on weeds control as well as their effect on certain crop characters of peanut Arachis hypogaea L. family leguminous, compared with unchemical control means. The results showed that pendimethalin, as pre-emergence treatment, at recommended rate, gave the highest reduction in number and dry weight of weeds per sq. meter. Whereas clethodim as post-emergence treatment at half recommended rate recorded the least effect. Mechanical mean weed free had the superior effect after 75 and 105 days from sowing, followed pendimethalin and clethodim at (recommend rate) in 2004 and pendimethalin in 2005. The results also showed that clethodim as post-emergence treatment at recommend rate was the most effective's treatment reduction on dry weight of weeds. Weed free caused percentage reduction of dry weight ranged from 91.5 to 99.8%. The results also showed that the tested herbicides increased the dry weight, pod yield and yield components, whereas there were no significant effect on the crude protein and oil content in seeds between all treatments and unweeded treatment.
