“…forests or grasslands). Therefore, the effect of biotic and abiotic factors on the plants species and richness in deserts still is not completely studied (Miriti et al, 2007;Bertiller et al, 2009;Bisigato et al, 2009;Wang et al, 2013;Wu, Yang, 2013;El-Ghani et al, 2012;Barakat et al, 2014;Shaltout et al, 2016).…”

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.

“…Plant patches induce the formation of "fertility islands", which concentrate soil resources such as N and organic C under plant canopies, while relatively infertile soils occur in the inter-canopy spaces (Burke et al, 1999;Tongway & Ludwig, 2005;Bertiller et al, 2009). In these ecosystems, increasing aridity leads to the replacement of grasses by shrubs and a decrease in plant cover and productivity (Reynolds et al, 1997).…”

Resumen. En el Área Natural Protegida Presidente Sarmiento (APN), ubicada en la depresión intermontana del valle de Zonda, región del centro-oeste de Argentina, se cartografiaron los factores relieve, consistencia y estado de humedad de los suelos y vegetación, con el fin de contribuir al manejo del humedal. Éste se ubica en la porción distal de un extenso abanico aluvial, en coincidencia con la zona de descarga de agua. Se efectuó un análisis multidisciplinar para establecer relaciones entre la diversidad de hábitats y relieves, la vegetación y los suelos. Se identificaron y clasificaron genéticamente 10 ambientes regionales en la cuenca, donde el ANP ocupa 2 de estos 10 ambientes. A escala local, con fotos aéreas y trabajo de campo, se identificaron 7 sitios con sus variaciones en consistencia de suelos y vegetación. Se clasificaron 37 especies agrupadas en 18 familias. Las Fabaceae y Asteraceae son predominantes. En la reserva, el tamarindo (Tamarix gallica) resultó ser la especie exótica más adaptable; invade y desplaza a las especies nativas. La metodología de trabajo resultó ser muy útil, comenzando desde lo regional hasta el análisis del relieve local. Palabras clave: desiertos argentinos, humedal de descarga de agua subterránea, Tamarix gallica.
