Hashem Department of Botany, Faculty of Science, Ain Shams Univ., Cairo, Egypt Abstract: The present study aim at identifying the ecophysiological behavior of ten xerophytic species in relation to different habitat and stress conditions during winter and summer along Al-Alamein-Alexandria international desert road. Physical and chemical changes in soil along the different examined sites were reflected in changing plant community types. The selected plant species comprise: Haloxylon salicornicum, Anabasis articulata, Zygophyllum decumbens, Agathophora alopecroids, Cornulaca monocantha, Artemisia monosperma, Echinops spinosus, Thymelia hirsuta, Deverra triradiata and Noaea mucronata. Mechanical analysis revealed that soil associated with the studied plants is consisted of different fractions; coarse and fine sand being the dominant fractions for all samples. The contents of succulence, photosynthetic pigments, carbohydrates, nitrogenous compounds, proline and minerals were analyzed and the results showed that, although the studied species belonging to one ecological group; xerophytes, there were wide difference in their metabolism, indicating the wide range of adjustment mechanism behaved by such plants under comparable habitat conditions. In contrast to organic solutes, inorganic ions (in some of the selected species) formed the largest component contributing to osmotic adjustment.

Res., 4(10): 1276-1284, 2008 MATERIALS AND METHODS The work was carried out during winter and summer seasons, of three successive years 2005-2007. Climate: The climatic data of the area under study was collected from three meteorological stations El-Dabbaa, Wadi El-Natron and Gianaclis. Maximum and minimum mean values of temperature (°C), annual precipitation (mm) and the relative humidity (%) were determined for the selected sites. Study Area: The area extending along the international Alex-Al-Alamein road is located between latitude 30°29'74'' to 30°43'65'' North and 30°08'71'' to 29°01'14'' East. It extends about 133 km from Marina-Al Alamein (on the Mediterranean coastal region) in the North to Wadi El- Natron in the south (Fig. 1). Except for the narrow Mediterranean coastal belt which is the wettest region of Egypt, the whole western desert (including the studied area) is one of the extremely arid parts of the world. Geomorphology of the Studied Area: The studied area Fig. 1: Map showing the Cairo – Alexandria Desert Road is located in the Libyan portion of the Sahara which is (modified after Zahran and Willis 1992) called now the western desert of Egypt as it occurs west of the river Nile.

  • On the Winter and Spring Aspect of the Macrolepidoptera Fauna of Jordan with Remarks on the Biology of Some Species
    © Münchner Ent. Ges., download www.biologiezentrum.at Mitt. Münch. Ent. Ges. 102 65-93 München, 15.10.2012 ISSN 0340-4943 On the winter and spring aspect of the Macrolepidoptera fauna of Jordan with remarks on the biology of some species (Lepidoptera: Tineoidea, Cossoidea, Bombycoidea, Papilionoidea, Geometroidea, Noctuoidea) Dirk STADIE and Lutz LEHMANN († 1) Abstract The results of two lepidopterological expeditions to Jordan from December 20 to December 30, 2008 (provinces of Irbid, Karak, Tafila und Ma’an) and March 19 to March 25, 2009 (provinces: Zarqa, Tafila, Irbid and Balqa) are presented. A total of 166 species of Macrolepidoptera could be recorded, among them 21 species new for Jordan. Desertobia heloxylonia lawrencei subsp. n. is described. The female genitalia of Odontopera jordanaria (STAUDINGER, 1898) comb. n., are figured for the first time. The larvae of Odontopera jordanaria STAUDINGER, 1898, Minucia wiskotti (PÜNGELER, 1902), Allophyes benedictina (STAUDINGER, 1892), Agrochola pauli (STAUDINGER, 1892), Agrochola scabra (STAUDINGER, 1892), Agrochola staudingeri RONKAY, 1984, Conistra acutula (STAUDINGER, 1892), Polymixis apora (STAUDINGER, 1898) and Polymixis juditha (STAUDINGER, 1898) are described and figured. Introduction Our knowledge of the winter aspect of the macrolepidoptera fauna of the southwestern Palaearctic region is still lower compared to other seasons. It has been shown during expeditions that in countries with subtropical- mediterranean climate an interesting macrolepidoptera fauna with numerous poorly known or even new species could be ascertained, in the eremic as well as in the steppe and mediterranean zone. The focus of this communication is on the Noctuidae family, because Noctuid species dominate the species composition in winter (e.g.

  • A Synopsis of the Family Chenopodiaceae in India
    Pleione 6(2): 273 - 297. 2012. ISSN: 0973-9467 © East Himalayan Society for Spermatophyte Taxonomy A synopsis of the Family Chenopodiaceae in India T. K. Paul Botanical Survey of India, Central National Herbarium, Howrah-711103, India E- mail: [email protected] Received revised 07.12.2012; Accepted 11.12.2012 Abstract The present paper presents a concise account of Chenopodiaceae in India. In all 19 genera with 50 species, 1 subspecies, 3 varieties have been recognized and another 2 genera and 14 species are cultivated or introduced. The genera and species are arranged in alphabetical order. Within the enumeration Key to genera and species, correct nomenclature, reference to type materials wherever available, phenology and distribution also have been added. Key words: India, Chenopodiaceae, Synopsis, comb. et stat. nov. INTRODUCTION The plants of Chenopodiaceae Ventenat, commonly known as ‘Goosefoot’ family, are mostly grow as weed and some are food plants like spinach, chard, beets, sugar beet and quinoa. The family is placed in the order Caryophyllales by Cronquist (1981), Takhtajan (1969) and Dahlgren (1975). Hutchinson (1959) and Thorne (1968, 1992) included the family in the order Chenopodiales, Ulbrich in Engler & Prantl (1934) in the order Centrospermae and Bentham & Hooker (1880) in the series Curvembryeae. Bentham & Hooker (1880) divided the family into two series, cyclobeae and spirolobeae. Cyclobeae is characterized by annular embryo, albumen copious whereas in spirolobeae the embryo is spiral and albumen scanty or absent. Williams & Ford-Lloyd (1974) recognised three subfamilies: Chenopodieae (embryo cyclical, operculum absent, endosperm absent, ovary superior), Salsoleae (embryo spiral, operculum absent, endosperm absent, ovary superior), Beteae (embryo cyclical, operculum present in fruit, endosperm present, ovary semi-inferior).

E.1 1Faculty of Science and Arts at Al Rass, Qassim University, Saudi Arabia (fax: +9661633351600) 2Faculty of Agriculture and Veterinary Medicine, Qassim University, Saudi Arabia *Corresponding author e-mail: [email protected] (phone+966502492660) (Received 25th May 2016; accepted 25th Aug 2016) Abstract. Stems of 14 species belonging to 10 genera of the family Chenopodiaceae were examined under scanning electron microscope (SEM). Micro-morphological characters such as sculpture of epicuticular wax, trichomes and surface relief were investigated. These characters were clumped into five groups. These groups do not coincide solely with the five tribes of the species studied. The study presented epicuticular wax sculptures and surface reliefs not previously reported for the family Chenopodiaceae. Keywords: scanning electron microscope, epicuticular wax sculpture, trichome, surface relief, semi-arid Introduction Epidermal characters as revealed by scanning electron microscopes (SEM) exhibit a variety of micro-morphological features (Barthlott, 1990), influenced by the environment (Sattler and Rutishauser, 1997; Koch and Ensikat, 2008), and act as a barrier against mechanical damages, insects, excessive light and loss of water (Bird and Gray, 2003; Rudall, 2007; Mauseth, 2008). These epidermal characters can reflect the relationships between habitat and phytogenetics of the plants (Liu, 2006). Chenopodiaceae Vent., commonly known as Goosefoot family, is cosmopolitan, especially diverse in arid, semi-arid, saline and hypersaline ecosystems (Kuhn et al., 1993; Hedge et al., 1997). Members of the family Chenopodiaceae are represented in the flora of Saudi Arabia by 74 species belonging to 23 genera which grow in many regions (Chaudhary, 1999), with Qassim Region accommodating a considerable number (Al-Turki, 1997).

AL-KHALIFAH* & A.E. SHANAVASKHAN *Natural Resources and Environmental ResearchInstitute, King Abdulaziz City for Science and Technology, Post Box No.6086, Riyadh 11442, Kingdom of Saudi Arabia Abstract: The distribution and status of Haloxylon persicum Bunge ('Ghada') have been evaluated for the Arabian Peninsula. Analysis of the data using IUCN guidelines showed that the taxon qualifies for the IUCN status 'lower risk' but 'conservation dependent'. Its geographical distribution is from nearer or above the Tropic of Cancer, up to 50 o N latitude. Phenological studies of the natural populations revealed vernal and aestival flowering. Vernal flowers produced viable seeds but aestival flowers were mostly male or very rarely polygamous. Seed germination studies were conducted to probe in to the poor regeneration in natural populations. Results indicated that deep burial of seed and the non-availability of adequate moisture in the germination medium are the main limiting factors for the population expansion. Ghada is a C 4 plant showing unusual behaviour of producing C 3 seedlings. These C 3 seedlings produced during winter help the taxon to perpetuate, even in adverse conditions of the desert. Resumen: La distribución y el estatus de Haloxylon persicum Bunge ('ghada') fueron evaluados en la Península Arábiga. El análisis de los datos usando los lineamientos de la IUCN mostró que este taxón merece el estatus de la IUCN de ‘bajo riesgo’ pero ‘dependiente de medidas de conservación’.
