Local versus landscape‐scale effects of savanna trees on grasses (2009, background): “…et al. 2001, 2004b; Treydte et al. 2007; Ludwig, de Kroon & Prins 2008), reduced evapotranspiration (Belsky et al. 1993; Breshears et al. 1997; Ludwig et al. 2001), increased soil water availability due to hydraulic lift (Ludwig et al. 2003), decreased soil water availability due to…”
Effects of Herbivory, Fire and N2-fixation on Nutrient Limitation in a Humid African Savanna (2008, background): “more than the less than 6 mentioned by Ludwig and others (2001) (Figure 4). We agree with Ludwig and others (2001) that the difference compared with temperate ecosystems is probably due to the very high N use efficiency of tropical C4 grasses (Sage and Pearcy 1987; Le Roux and Mordelet 1995 ).”
Water-removed spectra increase the retrieval accuracy when estimating savanna grass nitrogen and phosphorus concentrations (2011, background): “Mapping both N and P would allow computing of the N:P ratio, which is a key indicator of nutrient limitation in vegetation (Koerselman and Meuleman 1996; Ludwig et al. 2001).”
Water and nutrients alter herbaceous competitive effects on tree seedlings in a semi‐arid savanna (2009, methodology): “Our nitrogen fertilizer amount was comparable to that used by Ludwig et al. (2001), and is in line with local fertilizer recommendations for commercial, irrigated summer pastures (Dickinson et al. 1990).”
Trees improve grass quality for herbivores in African savannas (2007, methodology): “:P ratios were calculated to test for nutrient limitation (Ludwig et al., 2001).”
The influence of savanna trees on nutrient, water and light availability and the understorey vegetation (2004, background): “Outside of tree canopies the ratio was about 6, which clearly indicates N limitation (Ludwig et al. 2001).”
