“…it is well known that arid and semi-arid regions are vulnerable to landscape changes as well as other anthropogenic activities that have been recently increased due to fast development and urbanisation (nicholson, Farrar, 1994;nicholson et al, 1998;Evans, Geerken, 2004;Barakat et al, 2014;Hatim et al, 2016). The arid and semi-arid regions show interesting temporal variation in water availability and unique structure of floral communities (Snyder et al, 2004).…”

The present study aims to investigate the effect of soil physical and chemical variables on the species richness and the floristic composition in four sites (Alwaz, Alqan, Sharma and Zetah) of Tabuk region in the Northwestern part of Arabian Peninsula. Only organic matter (OM), pH and calcium (Ca) showed significant differences (P < 0.05) amongst the four studied sites. Only magnesium and sodium were selected in the forward regression model and showed to be strong drivers of species richness of plants in Tabuk region (Adj-R2 = 0.438, F2,13 = 6.85, P = 0.009). The multivariate analysis of canonical correspondence analysis (CCA ) was applied to reveal the effect of the physical and chemical variables on the species composition of the plants. The CCA classifies the plant species into three groups based on their preference to the environmental variables. The first group of plant species (Group 1) is characterised by positive preference to the chloride (Cl) and negative relationship with OM and pH. The second group (Group 2) is positively correlated with most of the soil variables such as OM, calcium (Ca), potassium (K), bicarbonate (HCO3), electrical conductivity (EC), sulphate (SO4) and sodium (Na). The third group (Group 3) has positive relationship with carbonate (CO3) and negative relationship with EC and magnesium (Mg). The chloride, sodium, sulphate, EC and carbonate are the main environmental factors influencing the plant species composition in Tabuk region. The cluster analysis based on the Euclidian measure shows that Alqan and Zetah have closer species composition compared to Sharma.

“…The life-form spectra of the species recorded in the study area showed six types (Table 3), the majority of plant species are therophytes (61.9%), then hemicryptophytes (16.7), chamaephytes and geophytes of the same percent (7.14%), followed by phanerophytes (4.8%) and cryptophytes (2.4%). High percentage of therophytes coincide with the floristic characters of the arid zones [34] (Fig. 2).…”

Groundwater in Egypt plays an important role in the country's water budget. South Western desert represent an arid of desert biome within world's net-work of the biosphere reserves. In this study, the plant wild vegetation were surveyed in Abu Tartur mining area located in the Southern part of Western depending essentially on the seepage from water line tubes which supplies water demands at Abu Tartur. The vegetation-environment relationships in Abu Tartur are described. Data sets (42 species in 38 plots) beside the pip-line enriched from 13 wells were analyzed, using multivariate procedures, i.e., two-way indicator species analysis (TWINSPAN), detrended correspondence analysis (DCA) and detrended canonical correspondence analysis (CCA), to produce a classification of plant communities in the studied areas and to examine the relationships of that plant communities to certain edaphic factors. Five plant communities were identified. Astragalus vogelii, Chenopodium murale, Citrullus colocynthis, Fagonia arabica, Farsetia aegyptia, Hyoscyamus muticus, Morettia philaeana, Cynodon dactylon, Trichodesma africana, Tamarix nilotica, Senna italica, Schouwia purpurea, Salsola volkensii andPhragmites australis were common in the study area. Phytochemical survey for nitroprpionic compounds in some taxa belonging to Fabaceae family showed the absence of these toxic compounds by using GC/MS analysis. Also some phytochemical components of Astragalus vogalii were extracted and identified by GC/MS spectra. A biological activity, in this regard was the screening of methanol extracts for some wild taxa of Abu Tartur against natural Tetranychus urticae as acricidal activity and the methanol extracts of some taxa give high mortality results, like Farsetia aegyptia (86.6%) and Fagonia arabica Burm. f. (70.0%).

“…Since habitats such as wadi beds, slopes etc. accumulate maximum moisture; plant associations that inhabit such habitats possess the highest species richness and species turnover [11]. Gulf of Aqaba is of great significant from a biological point of view, due to its geographic location at the junction of two climatic zones (Mediterranean and arid) and three phytogeographical units such as Saharo Arabian, Mediterranean and Irano-Turanian.…”

Floristic diversity of the coastal regions of Gulf of Aqaba has been compiled based on the vegetation survey with consultation of literature and herbarium collections during two spring seasons of 2016 and 2017. A total of 109 species belonging to 86 genera in 36 families are recorded in the study area; of which above 50% of the taxa falling in 6 dominant families. Amaranthaceae 23% is the dominant family followed by Poaceae 17%, Fabaceae 7 and 3% Asteraceae. Various vegetation units belonging to three major habitats such as sabkhas, wadis and hilly areas, three life-forms and chorological units have been identified. Based on the physiognomic study the climate of the study area is classified as a transition zone between Mediterranean and sub-Saharan arid zone. A high number of ephemerals in the area indicate dry climate prevailing in these areas. Halophytes dominate along the coastal zone, ephemerals in wadi-bed and chamaephytes in foothills and slopes.
