Depth of water acquisition by invading shrubs and resident herbs in a Sierra Nevada meadow (2006, background): “…and trees often grow long tap roots, allowing them sole access to deep soil water while herbaceous species develop their shallow roots and compete strongly for shallow soil water (Cline et al., 1977; Gibbens and Lenz, 2001; Ludwig et al., 2004; Polley et al., 1997; Schwinning and Ehleringer, 2001).”
An optimality-based model of the coupled soil moisture and root dynamics (2008, unknown): “This is in line with ﬁeld observations elsewhere, which showed that tree roots take up more water from shallow soil than they exude via hydraulic lift (Ludwig et al., 2004).”
Facilitation of Quercus ilex in Mediterranean shrubland is explained by both direct and indirect interactions mediated by herbs (2010, background): “Competition for water has been shown to be a major interaction between herb species and tree seedlings in water-stressed systems (Knoop & Walker 1985; Ludwig et al. 2004; van der Waal et al. 2009), while competition for nutrients is more commonly involved in mesic systems (Pagès & Michalet 2003).”
Belowground competition in a broad-leaved temperate mixed forest: pattern analysis and experiments in a four-species stand (2009, background): “Current research focuses on the importance of root competition relative to other factors in determining growth and survival of plants and in affecting the diversity and species composition of plant communities (e.g. Rajaniemi et al. 2003; Ludwig et al. 2004).”
Plant interactions govern population dynamics in a semi‐arid plant community (2005, background): “…woody species on their understorey occurred at the beginning of the growing season, i.e. when water was readily available (Holzapfel & Mahall 1999; Ludwig et al. 2004) or during rainy years, but shifted to neutral or competitive during severe water shortage (Tielbörger & Kadmon 2000; Ludwig et…”
Tree effects on grass growth in savannas: competition, facilitation and the stress‐gradient hypothesis (2013, background): “In savannas, trees may suppress grass growth through direct competition for water, light and nutrients resulting from overlapping root profiles and canopy shading (Scholes & Archer 1997; Ludwig et al. 2004b).”
Root responses to nutrients and soil biota: drivers of species coexistence and ecosystem productivity (2012, background): “…of both shrubs and grasses in the upper soil layers (Rodrı́guez, Bertiller & Bisigato 2007), limited partitioning of soil resources between these lifeforms (Kulmatiski et al. 2010) and reduced grass growth due to root competition with trees for water in the upper soil layers (Ludwig et al. 2004).”
Refining the stress‐gradient hypothesis for competition and facilitation in plant communities (2009, unknown): “…driver of stress − situations potentially found in environments such as arid and semi-arid areas (e.g. Reynolds et al. 2000; Carrick 2003; Hipondoka et al. 2003; Ludwig et al. 2004b) − shifts in the balance of net interactions from competition to facilitation with increasing stress are less likely.”
