“…The nursing effect may result from many factors including crown architecture, shading increment, temperature buffering, increases in soil moisture and nutrition, protection against herbivores, and enhancement of beneficial soil organisms (Padilla and Pugnaire, 2006;Callaway, 2007). The biology and usefulness of nurse plants have been investigated in many degraded habitats, including Mediterranean mountains, alpine habitats, arid deserts, semi-arid shrublands, savannas, ecotones between farmland and pasture, tropical sub-humid forests, and marshes (Bertness and Yeh, 1994;Callaway et al, 1996;Carrillo-Garcia et al, 1999;Castro et al, 2002;Arroyo et al, 2003;Sanchez-Velasquez et al, 2004;Armas and Pugnaire, 2005;Aerts et al, 2006). Recently, we began investigating the ecology of nurse plants in South China .…”
