Effect of environmental factors on the flora of alluvial fans in southern Sinai

Effect of Altitudinal Variations on the Distribution of Nepeta Septemcrenata in Saint Katherine Protectorate, South Sinai, Egypt.

“…The results show that elevation influence on physical and chemical properties of soil as shown in Table 2. Water content show great variation among different elevation ranks and this agrees with results recorded by (El-Ghareeb and Shabana, 1990; Moustafa and Zaghloul, 1993;Moustafa and Zayed, 1996;Whittaker, 1975;Peet, 1988), low elevation wadies show the highest values while high elevation wadies show the lowest values. Plant traits were also affected by elevation gradient as shown in Figure 2 and Table 4.…”

Vegetation communities on the shores of a salt lake in semi-arid Western Australia

“…It is concluded that depth to ground-water and soil texture are likely to be the two environmental factors that most directly govern vegetation communities on the lake shores, with soil salinity strongly influenced by both these factors. Soil texture has been shown to be a significant factor in comparable environments in the Middle East where it has been shown to be indicative of particular vegetation types (Bo¨er, 1996;Moustafa and Zayed, 1996;Bo¨er and Sargeant, 1998).…”

Soil–vegetation relationships in semi-arid Mediterranean old fields (SE Spain): Implications for management

“…Gravel content and edaphic variables related to salinity such as electrical conductivity or ionic content, have been found to determine vegetation changes in other arid territories (Abd El-Ghani and Amer, 2003; Moustafa and Zayed, 1996). It is well known that soil salinity is a major factor in the vegetation distribution as well as soil moisture (Pennings and Callaway, 1992), especially in arid and semi-arid regions (Maestre et al, 2003).…”
