| Zusammenfassung |
| Patterned vegetation is characterisic for water-limited areas and
both periodic and scale-free distributions of vegetation patch sizes
have been reported. Using a simple common mathematical modeling
approach we study the physical and ecological conditions
for the emergence of both types of patterns. By drawing an
analogy between the vegetation model and a simpler inhibitor-activator
model we discuss if scale-free patterns of dryland vegetation
represent asymptotic patterns or more likely long transients. |
