Periodic versus scale-free patterns in dryland vegetation.
Two major forms of vegetation patterns have been observed in drylands: nearly periodic patterns with characteristic length scales, and amorphous, scale-free patterns with wide patch-size distributions. The emergence of scale-free patterns has been attributed to global competition over a limiting resource, but the physical and ecological origin of this phenomenon is not understood. Using a spati...
متن کاملA morphometric analysis of vegetation patterns in dryland ecosystems
Vegetation in dryland ecosystems often forms remarkable spatial patterns. These range from regular bands of vegetation alternating with bare ground, to vegetated spots and labyrinths, to regular gaps of bare ground within an otherwise continuous expanse of vegetation. It has been suggested that spotted vegetation patterns could indicate that collapse into a bare ground state is imminent, and th...

متن کاملCoupling vegetation organization patterns to soil resource heterogeneity in a central Kenyan dryland using geophysical imagery
[1] In dryland ecosystems, understanding the effects of heterogeneity in soil moisture and geophysical properties on vegetation structure and dynamics poses a suite of challenging research questions. Heterogeneity in soil depth can affect resource availability and the subsequent organization of woody vegetation, while spatiotemporal variation in soil moisture can reveal important ecohydrologica...
متن کاملPatterns as indicators of productivity enhancement by facilitation and competition in dryland vegetation
[1] Well-defined vegetation patterns are a widespread feature of dryland landscapes, where spotted, banded, or other organized systems of vegetation patches are bordered by bare soil. A number of different mechanisms have been invoked to explain the emergence of these patterns and to associate their geometrical features to the driving (biotic and abiotic) processes. A commonly accepted theory o...
