The purpose of this study was to describe the flora and vegetation at Qift-Qusier roadsides in the central part of the Eastern Desert of Egypt, and to relate floristic composition to edaphic conditions. A total of 61 species (28 annuals and 33 perennials) belonging to 50 genera and 27 families were recorded. On the basis of their presence values, classification of the 61 species recorded in 43 stands by cluster analysis yielded six vegetation groups. The results of CCA ordination indicated that the soil organic matter, Na, K, Ca, and pH were the most important factors for distribution of the vegetation pattern along the road verges in the study area. The DCA and CCA results suggested a strong correlation between vegetation and the measured soil parameters.

Mota, Javier Navarro, Julio Pen˜as & Esther Gime´nez *Departamento de Biologı´a Vegetal y Ecologı´a. Universidad de Almerı´a, E-04120 Almerı´a, Spain (Received 30 January 2002, accepted 11 June 2002) The aim of this study is to assess the Iberian populations of Forsskaolea tenacissima L. according to its biogeographical interest, habitat, geographical range and conservation status. Results point out that they are restricted to gravel wadis of Tabernas Desert (SE Spain), are scarcely included in protected areas and represent historically isolated populations with relict behaviour. We also describe a new association, Senecioni-Forsskaoleetum tenacissimae. Conservation status of species is cause for concern and two conservation actions must be carried out. Firstly, protected areas should house Forsskaolea populations and secondly, phytosociological characteriza- tion of a community allows inventorying its habitat and directing conserva- tion efforts to community level. # 2002 Elsevier Science Ltd. Keywords: biodiversity; flora; phytosociology; protected areas; reduced geographical range; relict populations; semi-arid ecosystems; Tabernas Desert Introduction The origin of the steppe areas in the Iberian Peninsula along the Pleistocene is an old classic controversial issue. The so-called ‘Steppe Theory’ (Del Villar, 1915) considered the vegetation of these ecosystems as the result of the destruction of primitive sclerophilous forests. For this reason the flora and vegetation of these ecosystems have been undervalued for conservation priorities.

BAKHT1* Department of Botany, University of Hazara, 1Institute of Biotechnology and Genetic Engineering, University of Agriculture, Peshawar, Khyber-Pakhtunkhwa-29120, Pakistan Sher, et al.: Pharmacological Evaluation of Forsskaolea tenacissima The current research work was carried out to investigate the antimicrobial, antinociceptive and antipyretic activities of different solvent extracts of Forsskaolea tenacissima. This investigation revealed that ethyl acetate extract exerted maximum inhibition (56%) of the growth of Providencia mirabilis and 48% of Aspergillus fumigatus. Penicillium was the most resistant fungi and was unaffected by any extracts. The analgesic activity of these extracts at a dose of 150 mg/kg increased the reaction time after 60, 90, 120 and 180 min compared to the initial latency as well as that of control group in the hot plate method. The number of writhes recorded after 150 mg/kg extract were comparatively lower (56±3.74) than that of normal saline group (76±4.15) in acetic acid-induced writhing test. The antipyretic effect of the plant extracts at 300 mg/kg was comparable with normal saline.

  • Chapter 1 Arabia and the Study of the Ancient Near
    Cambridge University Press 978-0-521-86231-8 - Cambridge World Archaeology: The Archaeology of Prehistoric Arabia: Adaptation and Social Formation from the Neolithic to the Iron Age Peter Magee Excerpt More information CHAPTER 1 ARABIA AND THE STUDY OF THE ANCIENT NEAR EAST INTRODUCTION If there is any country which is seen to lie completely outside the stream of ancient history, it is Arabia. In spite of its vast extent; in spite, too, of its position in the very center of the civilized empires of the ancient East, midway between Egypt and Babylon , Palestine and India, – its history has seemed almost a blank. For a brief moment, indeed, it played a conspicu- ous part in human aff airs, inspiring the Koran of Mohammed, and forging the swords of his followers; then the veil was drawn over it again, which had previously covered it for untold centuries. We think of Arabia only as a country of dreary deserts and uncultured nomads, whose momentary infl uence on the history of the world was a strange and exceptional phe- nomenon. (Sayce 1889 : 406) Thus wrote Archibald Henry Sayce, the great Welsh professor of Assyriology at the University of Oxford in 1889. Sayce countered his own introduction by then expounding upon how the study of ancient inscriptions during the pre- vious decades had begun to cast light on the rich history of pre-Islamic Arabia. The possibility that Arabia had a prehistoric past, that is, human occupation before the era when inscriptions became common in the eighth century BC, and that these prehistoric cultures were in some way worthy of study did not occur to Sayce, whose views not only were typical of his day but continued to be symptomatic of the position of Arabian studies for most of the twentieth century.

  • Impact of Elevation and Slope Aspect on Floristic Composition in Wadi
    www.nature.com/scientificreports OPEN Impact of elevation and slope aspect on foristic composition in wadi Elkor, Sarawat Mountain, Saudi Arabia Mohamed A. Fadl1,2, Hatim M. Al‑Yasi1 & Emad A. Alsherif2,3* The current research was carried out in Wadi Elkor, one of the Sarawat Mountains regions, which is a special location from an environmental standpoint and one of the only places in Saudi Arabia where a range of Palaearctic fora co‑exists with Afrotropical species. The study aimed to determine the foristic composition as well as the efects of slope aspect and elevation on species, life forms, and phytogeographical elements distribution. The study area is located in Wadi Elkor, a valley in the Sarawat Mountains that cuts of the Al‑Hada escarpment, 47 km southeast of Makkah City, Saudi Arabia. We conducted the research at three diferent locations, each with a diferent elevation and slope aspect. Based on foristic composition, Ward classifcation moreover Jaccard comparisons were performed. A total of 189 species was discovered, divided into 131 genera and 43 families. The current study identifed Argyrolobium rarum Dumme as a new vascular plant in Saudi Arabia’s terrestrial fora. In the current study, the Gramineae, Leguminosae, and Compositae families contributed 29% of the total plant species, whereas 14 families were represented by one species each. Solanum was the most numerous genus, with seven species, followed by Acacia and Pulicaria, each with six species, while Commicarpos and Euphorbia, each with four species. At an elevation of 1060 m above sea level, the north facing slope had the most plants, genera, and families.

ABSTRACT Aim: Due to the urgent need for anticancer agents, investigation of endophytes of medicinal plants growing in special environments is considered a promising approach for the search of bioactive natural products. Materials and Methods: The ethyl acetate extracts of the cultures of twelve endophytic fungi were isolated from the medicinal plants Calotropis procera fam Apocynaceae, Solanum nigrum fam Solanaceae and Forsskaolea tenacissima fam Urticaceae growing in one of the richest areas of plant biodiversity in Saudi Arabia, Najran. All isolated and identified endophytic fungi were subjected to preliminary screening assays for cytotoxic activity. Results: Four of the isolated endophytic fungi (Cladosporium herbarum (1), Hortaea werneckii (2), Penicillium solitum (3) and Eurotium chevalieri (4)) exerted cytotoxic activity against HepG2, T-47D, HCT-116 and RAW 264.7 in the MTT cell viability assay. The highest cytotoxic effects were observed for the extract of Penicillium solitum on HepG2 and HCT-116 cell lines with IC50 values of 13 µg/ml and 42 µg/ml, respectively.

Both species inhabit arid Mediterranean ecosystems (with Stipa tenacissima or Lygeum spartum as predominat species) and are under a severe risk of extinction at the regional level, due to the narrow geographic range of both species and the low number of mature individuals in the scarce known Iberian populations.

    INTERNATIONAL JOURNAL OF AGRICULTURE & BIOLOGY 1560–8530/2007/09–2–202–214 http://www.fspublishers.org Comparative Study on the Vegetation of Protected and Non- protected Areas, Sudera, Taif, Saudi Arabia HOSENY A.M. MOSALLAM Department of Biology, Collage of Science, Taif University, Hawyia, Taif, Kingdom of Saudi Arabia E-mail: [email protected] ABSTRACT This study was carried out at the National Wildlife Research Center (NWRC), located 45 km southern east of Taif governorate, Saudi Arabia. Three localities with different degrees of conservation were ecologically analyzed with respect to their vegetation cover, frequency, abundance and soil characteristics. Plant species were classified into three main communities dominated by Arnebia hispidissima, Aizoon canariense and Argemone mexicana communities depending on their degree of protection three life forms: therophytes, chamaephytes and phanerophytes constitute about 85.6% of the total flora of the reserves. Also, 40.8% of the recorded species are uni-regional. The application of CCA indicated that the plant species is controlled in their distribution by ten soil characteristics. 18 plants species were eaten by houbara, 10 species were eaten by ostrich and each of oryx and gazelle depended on 12 different species in the old and new protected areas. Overgrazing outside the reserves has bad effect not only on the plant life but also on the soil development. The vegetation in the reserves, in general, is relatively richer and the soil shows no symptoms of erosion. Productivity of the protected area was much higher than the adjacent un-protected ones. Key Words: Vegetation; Overgrazing; Trampling; Oryx; Houbara INTODUCTION in arid regions.
