“…Furthermore, the increases in silt and clay and the accumulation of plant litter were favorable for soil structure improvement, thus resulting in the decrease of soil bulk density. Soil water content is the primary factor that affects plant establishment and growth in arid soil systems (Schlesinger et al, 1996), and therefore, water shortage can be a critical factor limiting primary production (Ruiz et al, 2007). The results of the present study indicated that the soilewater environment of the C. microphylla shrubs was poor ( Fig.…”

“…The principal factors are the shrub species (Titus et al, 2002) and habitats (Derner et al,1997;Su et al, 2004). The rate at which litter and soil nutrients accumulate under shrubs may differ among species due to vegetative cover (Li et al, 2008a), nitrogen absorption and mineralization (Quideau et al, 1999;Ruiz et al, 2007), and stem runoff (Martinez-meza and Whitford, 1996). It is evident that shrub species differ in their contributions to fertile islands by absorbing various minerals in different quantities (Quideau et al, 1999;Wezel et al, 2000).…”

“…Los ecosistemas de zonas áridas y semiáridas se caracterizan por una distribución heterogénea de recursos (Housman et al, 2007;Xu et al, 2012), y una limitada productividad primaria. Esto debido a la alta radiación solar, las altas tasas de evapotranspiración, las restricciones en la disponibilidad del agua y la baja movilidad de nutrientes en el suelo, especialmente de nitrógeno y fósforo (Dossa et al, 2009;Ruiz, et al 2008).…”

“…Los HMA son un componente microbiano constante e importante en la rizósfera y en las raíces de las plantas de ecosistemas áridos y semiáridos, se estima que más del 80% de las especies vegetales en estos ambientes establecen la simbiosis MA 9,10 , entre ellas grupos emblemáticos como las cactáceas 11 , gramíneas 12 y leguminosas del género Prosopis L. y Mimosa L.; en particular, estas leguminosas son elementos importantes en la estructura de los matorrales xerófilos 13,14 , al actuar como reservorios de propágulos micorrícicos 15 y contribuir a la fertilidad del suelo con materia orgánica, nitrógeno y fósforo al formar islas de recursos (IR) [14][15][16][17] que favorecen el establecimiento y supervivencia de otras especies vegetales bajo su copa 17 como las cactáceas 18 .…”
