Savannas are globally important ecosystems of great significance to human economies. In these biomes, which are characterized by the co-dominance of trees and grasses, woody cover is a chief determinant of ecosystem properties. The availability of resources (water, nutrients) and disturbance regimes (fire, herbivory) are thought to be important in(More)
1. Understanding and accurately predicting the spatial patterns of habitat use by organisms is important for ecological research, biodiversity conservation and ecosystem management. However, this understanding is complicated by the effects of spatial scale, because the scale of analysis affects the quantification of species-environment relationships. 2. We(More)
Multiple stable states, bifurcations and thresholds are fashionable concepts in the ecological literature, a recognition that complex ecosystems may at times exhibit the interesting dynamic behaviours predicted by relatively simple biomathematical models. Recently, several papers in Global Ecology and Biogeography, Proceedings of the National Academy of(More)
The potential relationship between climate change and conflict is intriguing and warrants rigorous study. However, the proposition by Burke et al. (1) that warming may be a directly causative factor in the risk of civil war in Sub-Saharan Africa seems unlikely. Theanalysis ofBurke et al. (1) suggests instead a tenuous historical association between warming(More)
The woody vegetation of the Kruger National Park varies greatly in species composition, biomass and cover at regional scales. This variability is associated primarily with broad-scale geological and climatic variations. At landscape scales woody density and cover are highly variable, associated with event-driven woody establishment and mortality processes,(More)
The primary objective of this study is to identify macro emergent phenomena pertaining to landuse transitions within the Missisquoi Watershed, Vermont, by accounting for land managers’ landuse decision making processes with respect to landscape characteristics, climate change scenarios and public policies. Due to the heterogeneity and the complexity of the(More)
