  • crossroads spontaneous organizational reconfiguration a historical example based on xenophon s Anabasis
    Organization Science, 1996
    Co-Authors: Kenneth E. Aupperle
    Abstract:

    This paper examines an ancient historical event that has profound implications regarding the role of organizational culture in facilitating spontaneous organizational reconfiguration. Xenophon’s Anabasis documents the successful retreat of a Greek army trapped in Persia in a setting that is comparable to the hypercompetition of today. Spontaneous reconfiguration is seen here to be a vital survival element in hypercompetitive environments, past and present. As a result, a historical case is used as a time-bridge to reveal the importance of rapid and substantive organizational redesign when confronting highly competitive and quickly shifting environments. The Anabasis is also used to animate several of Gareth Morgan’s (Morgan, G. 1986. Images of Organization. Sage Publications, Newbury Park.) metaphors. In particular, metaphors pertaining to a biological organism, the brain, and culture are used to parallel the Greek emphasis on body, mind, and spirit. While Xenophon’s army is depicted here in terms of bein…

  • Unripe red fruits may be aposematic.
    Plant signaling & behavior, 2009
    Co-Authors: Simcha Lev-yadun, Gidi Ne'eman, Ido Izhaki
    Abstract:

    The unripe fruits of certain species are red. Some of these species disperse their seeds by wind (Nerium oleander, Anabasis articulata), others by adhering to animals with their spines (Emex spinosa) or prickles (Hedysarum spinosissimum). Certainly neither type uses red coloration as advertisement to attract the seed dispersing agents. Fleshy-fruited species (Rhamnus alaternus, Rubus sanguineus and Pistacia sp.), which disperse their seeds via frugivores, change fruit color from green to red while still unripe and then to black or dark blue upon ripening. The red color does not seem to function primarily in dispersal (unless red fruits form advertisement flags when there are already black ripe fruits on the plant) because the red unripe fruits of these species are poisonous, spiny, or unpalatable. The unripe red fruits of Nerium oleander are very poisonous, those of Rhamnus alaternus and Anabasis articulata are moderately poisonous, those of Rubus sanguineus are very sour, those of Pistacia sp. contain unpalatable resin and those of Emex spinosa and Hedysarum spinosissimum are prickly. We propose that these unripe red fruits are aposematic, protecting them from herbivory before seed maturation.

  • Plant Life along the Saudi Red Sea Coast Islands 45 Plant Life along the Saudi Red Sea Coast Islands 1. Tawila Archipelago and Ghurab Island
    , 2016
    Co-Authors: Zeinab A. R, El Karemy, Hassan S. Al-zahrani
    Abstract:

    ABSTRACT. Tawila Archipelago consists of four islands. It lies west of Al Leith city, between the coordinates: Latitudes 20º09 ′ and 20º15′N, Longitudes 40º00 ′ and 40º15′E. Ghurab island is situated south of Jed-dah (Latitude 21º35′N and longitude 39º10′E). The mangrove species Avicennia marina occupies the eastern sides of Sharifa and Tawila is-lands, whereas the swampy areas of Ghurab and Tawila islands are occupied by Urochondra setulosa grass. Limonium cylindrifolium is recorded from the inland parts of Sharifa and Tawila islands, while species such as Anabasis ehrenbergii, Taverniera lappacea and Cy-perus conglomeratus inhabit the elevated parts of the latter island. Ob-vious stratification of vegetation occurs in the Sharifa island. A plant community dominated by Limonium cylindrifolium and Anabasis eh-renbergii was recognised in Tawila island. The impact of high salinity, extreme aridity and the scanty rains af-fect greatly the number of species encountered in the area of study. Only 17 species, representing 11 families of vascular plants, of which 14 perennials were recorded

  • Amycolatopsis Anabasis sp. nov., a novel endophytic actinobacterium isolated from roots of Anabasis elatior.
    International journal of systematic and evolutionary microbiology, 2020
    Co-Authors: Hong-fei Wang, Rui Gao, Yuan-guo Xie, Min Xiao
    Abstract:

    A novel endophytic actinobacterium, designated strain EGI 650086T, was isolated from the roots of Anabasis elatior (C.A.Mey.) Schischk. collected in Xinjiang, north-west China. The taxonomic position of the strain was investigated using a polyphasic taxonomic approach. Growth occurred at 15–40 °C, pH 6.0–8.0 and in the presence of 0–6 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequence and concatenation of 22 protein marker genes revealed that strain EGI 650086T formed a monophyletic clade within the genus Amycolatopsis and shared the highest sequence similarities with Amycolatopsis nigrescens JCM 14717T (97.1 %) and Amycolatopsis sacchari DSM 44468T (97.0 %). Sequence similarities with type strains of other species of the genus Amycolatopsis were less than 97.0 %. The average nucleotide identity and DNA–DNA hybrhybridization values between strain EGI 650086T and the reference strains were 78.1–79.8 % and 22.1–23.0 %, respectively. The genome of strain EGI 650086T was 10.9 Mb, with a DNA G+C content of 70.1 mol%. The diagnostic diamino acid in the peptidoglycan was meso-diaminopimelic acid. The major whole-cell sugars contained arabinose, galactose, glucose and ribose. The predominant menaquinones were MK-9 (H4) and MK-9 (H2). Major fatty acids were iso-C16 : 0 and summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B). The polar lipid profile of strain EGI 650086T included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, two unknown phospholipids, an unknown glycolipid and an unknown lipid. Polyphasic taxonomic characteristics indicated that strain EGI 650086T represents a novel species of the genus Amycolatopsis , for which the name Amycolatopsis Anabasis sp. nov. is proposed. The type strain is EGI 650086T (=KCTC 49044T=CGMCC 4.7188T).

  • Glycomyces Anabasis sp. nov., a novel endophytic actinobacterium isolated from roots of Anabasis aphylla L.
    International journal of systematic and evolutionary microbiology, 2018
    Co-Authors: Yongguang Zhang, Hong-fei Wang, Min Xiao, Dalal Hussien M. Alkhalifah, Xing-kui Zhou, Yonghong Liu, Wael N. Hozzein
    Abstract:

    A novel endophytic actinobacterium, designated strain EGI 6500139T, was isolated from the surface-sterilized roots of Anabasis aphylla L., collected from Xinjiang, northwest PR China, and subjected to polyphasic taxonomic characterization. Strain EGI 6500139T formed sparse aerial mycelium with rod-like spores. Whole-cell hydrolysates of the isolate contained meso-diaminopimelic acid as the cell-wall diamino acid, glucose as major sugar, and mannose, galactose, xylose and ribose as minor sugars. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, one unidentified glycolipid, one unidentified phospholipid and four unidentified polar lipids. The major fatty acids identified were anteiso-C17 : 0, anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0. The predominant menaquinones detected were MK-11 and MK-11(H2). The G+C content of the genomic DNA of strain EGI 6500139T was 70.4 mol%. Strain EGI 6500139T showed the highest 16S rRNA gene sequence similarity to Glycomyces lacisalsi XHU 5089T (96.3 %). Phylogenetic analysis showed that strain EGI 6500139T fell within the clade of the genus Glycomyces , and formed a clade with G. lacisalsi XHU 5089T and G. albus CCTCC AA 2013004T. Based on phenotypic, chemotaxonomic and phylogenetic data, strain EGI 6500139T represents a novel species of the genus Glycomyces , for which the name Glycomyces Anabasis sp. nov. (type strain EGI 6500139T=JCM 30088T=KCTC 29495T) is proposed.
