To determine the relationship between spatial dinoflagellate cyst distribution and oceanic environmental conditions, 34 surface sediments from Eastern Western Mediterranean Sea have been investigated for their content. Multivariate ordination analyses identified sea-surface temperature, chlorophyll-a , nitrate concentration, salinity, bottom oxygen concentration as main factors affecting in region. Based on relative abundance data, two associations can be distinguished that linked with major...
Ten new species of the coccolithophore genus Syracosphaera are described from temperate and sub-tropical to tropical waters: andruleitii sp. nov., castellata didyma hastata hirsuta leptolepis operculata reniformis serrata nov. squamosa An emended description is given for nanaKamptner. These other placed in a revised classification scheme genus, based on morphological structure endothecal exothecal coccoliths, coccosphere characteristics. The noroitica group introduced with murolithswith...
The increasing application of nanotechnology highlights the need to clarify and understand it. In this work, subacute toxicity Ag-NPs fresh water microalga Chlorella vulgaris marine Dunaliella tertiolecta were assessed. effect was induced by exposing both algae concentrations (0, 10, 50, 100 200 mg/L). Cellular viability reactive oxygen species (ROS) formation determined evaluate toxic on algal growth. Superoxide dismutase (SOD), catalase (CAT) peroxidase (POD) activities lipid peroxidation...

Abstract. Thirteen shallow boreholes were drilled by the Qattara Project Authority (QPA) on top of second limestone ridge in El-Dabaa area, along Mediterranean coast, northwest Egypt. Five foraminiferal biozones could be recognized ascending stratigraphic order: Heterostegina costata, Praeorbulina sicana, Borelis melo melo, Globigerinoides obliquus extremus zones and an un-named zone, embracing Middle Miocene Marmarica Formation Pliocene–Pleistocene Alexandria Formation.The deposition...
ABSTRACT A palynological investigation of the Nahr Umr, Mauddud and Ahmadi formations middle Cretaceous Wasia Group in Well DK-B Dukhan oil field Qatar, yielded 30 species dinoflagellate cysts, 18 pteridophytic spores, 14 gymnosperm pollen, 16 angiosperm pollen. Based on investigation, age Umr Formation is to late Albian. The basal part was deposited a marine prodelta or shallow shelf environment, whereas sedimentation upper took place normal conditions an inner at depths 10 80 meters....
ABSTRACT The Miocene carbonate Dam Formation is well exposed in the Jebel Al-Nakhash area of southern Qatar. Three sections were measured a detailed investigation Formation’s stratigraphy, micropaleontology, and paleoecology. This biostratigraphic paleoecologic study was supported by analysis microlithofacies foraminiferal assemblages. Microfossils are predominantly benthic foraminifera represented 38 species, many which milioline one larger form. A Borelis melo Local Range Zone Early...
Abstract The Lower Cretaceous Alam El Bueib and Alamein formations in the Ghazalat‐1 (GTX‐1) well, Western Desert, Egypt, consist of marginal marine siliciclastic sediments, overlain by Aptian evaporites (dolomite upper Formation). Angiosperm species diversity is reasonably high, account for 8.0–22.0% total palynomorphs. Most these might belong to monosulcate, zonasulculate, inaperturate pollen. genus Afropollis emended herein include forms with monosulcoid aperture. following two new...
