Spacing patterns of an Acacia tree in the Kalahari over a 61-year period: How clumped becomes regular and vice versa (2008, result): “As a result, our study supports that savannas are patch dynamic systems (Levin, 1992), as expressed by Gillson (2004a) and Wiegand et al. (2006).”
Trees improve grass quality for herbivores in African savannas (2007, background): “In savanna systems, older trees tend to be more widely spaced than smaller ones (Wiegand et al., 2006).”
What Limits Trees in C4 Grasslands and Savannas (2008, background): “Some African acacias have intrinsically short adult life spans (Midgley & Bond 2001, Wiegand et al. 2006), little longer than their life as suppressed saplings.”
Mapping vegetation morphology types in a dry savanna ecosystem: integrating hierarchical object-based image analysis with Random Forest (2014, background): “Vegetation structure and landscape composition in savanna systems is characterized as patchy, mainly as a result of high spatio-temporal variability in rainfall and fire history (Turner et al. 2003; Wiegand, Saltz, and Ward 2006).”
What are the effects of substrate and grass removal on recruitment of Acacia mellifera seedlings in a semi-arid environment? (2011, background): “We have long been interested in the factors that cause recruitment of one of southern Africa’s most serious encroaching species, Acacia mellifera (Ward 2005; Kraaij and Ward 2006; Wiegand et al. 2006; Britz and Ward 2007; Meyer et al. 2007a).”
The state of plant population modelling in light of environmental change (2008, background): “In principle, well designed (plant) population models can be used to provide an improved understanding of complex factors and processes influencing population and community change (e.g. Jeltsch et al., 1996, 1998, 1999; Wiegand et al., 2000; Colasanti et al., 2001; Bauer et al., 2002; Jeltsch and Mo”
