• Growth of N2‐fixing African savanna Acacia species is constrained by below‐ground competition with grass (2010, background): “Leguminous trees are an important component of subtropical savannas (Midgley & Bond 2001).”
• Tree–grass coexistence in savannas revisited – insights from an examination of assumptions and mechanisms invoked in existing models (2004, background): “…Skarpe 1992; Scholes & Walker 1993; Gignoux et al. 1997; Scholes & Archer 1997; Wilson & Witkowski 1998; Higgins et al. 2000; Jeltsch et al. 2000; Midgley & Bond 2001), and the available empirical evidence suggests that demographic bottlenecks imposed by such disturbances are a reality in many…”
• Plant reproductive susceptibility to habitat fragmentation: review and synthesis through a meta-analysis. (2006, background): “…therefore, to increase the study of these processes and their biological interactions with dispersers, predators, herbivores and competitors in fragmented systems, and eventually be able to make generalizations on these demographic processes as well (Midgley & Bond 2001; Hobbs & Yates 2003).”
• Grass competition induces N2 fixation in some species of African Acacia (2007, background): “Leguminous trees are an important component of the subtropical savannas (Midgley & Bond 2001) and are proliferating in many areas formerly dominated by grasses in a process known as ‘bush encroachment’ (O’Connor 1995; Hudak & Wessman 2001; Hudak et al .”
• Fire-related cues break seed dormancy of six legumes of tropical eucalypt savannas in north-eastern Australia (2003, background): “The second and third largest seeded species, Galactia tenuiflora and Crotalaria pallida, displayed the lowest tolerance to heat shock, with apparent mortality at 100� C. This contrasts with African acacias, where larger seeded species possess a greater tolerance of heat shock than those with smaller”
• A patch-dynamics approach to savanna dynamics and woody plant encroachment – Insights from an arid savanna (2006, background): “Nevertheless, they are not well understood (Midgley and Bond, 2001; Sankaran et al., 2004; Ward, 2005).”
• Resource pulses, species interactions, and diversity maintenance in arid and semi-arid environments (2004, background): “Seedling establishment is rare, not only due to water limitation, but also due to factors such as seed availability, temperature, herbivory, and fire (e.g., Grubb 1977; De Villalobos and Peláez 2001; Midgley and Bond 2001).”
• Consequences of herbivory by native ungulates for the reproduction of a savanna tree (2007, background): “reproduction, seedling survival and recruitment) might be equally important as or more important than adult survival in dictating tree abundance (Prins & Van der Jeugd 1993; Midgley & Bond 2001; Goheen et al. 2004; Sankaran et al. 2004).”
• Savanna woody plant dynamics: the role of fire and herbivory, separately and synergistically (2010, background): “Because all plants experience demographic bottlenecks, the question is what are the unique demographic bottlenecks of woody plants in savannas? The potentially unique aspect of their demography, given the prevalence of resprouting, is the recruitment bottleneck and importance of transitions for smal”
• What Limits Trees in C4 Grasslands and Savannas (2008, background): “In frequently burnt savannas, seedlings can acquire the ability to resprout within their first growing season (Hoffmann 1999, Midgley & Bond 2001).”
• How do small savanna trees avoid stem mortality by fire? The roles of stem diameter, height and bark thickness (2011, background): “Repeated topkill of small trees prevents recruitment into adult size classes and may ‘trap’ individual stems in the flame zone (sensu Midgley and Bond 2001).”
