A topographic mechanism for arcing of dryland vegetation bands
Punit Gandhi, Lucien Werner, Sarah Iams +2
Banded patterns consisting of alternating bare soil and dense vegetation have been observed in water-limited ecosystems across the globe, often appearing along gently sloped terrai…
Signatures of human impact on self-organized vegetation in the Horn of Africa
Karna Gowda, Sarah Iams, Mary Silber
In many dryland environments, vegetation self-organizes into bands that can be clearly identified in remotely-sensed imagery. The status of individual bands can be tracked over tim…
Assessing the robustness of spatial pattern sequences in a dryland vegetation model
Karna Gowda, Yuxin Chen, Sarah Iams +1
A particular sequence of patterns, "," occurs with decreasing precipitation in previously reported numerical simulations of PDE d…
Early-Warning Signs for Pattern-Formation in Stochastic Partial Differential Equations
Karna Gowda, Christian Kuehn
There have been significant recent advances in our understanding of the potential use and limitations of early-warning signs for predicting drastic changes, so called critical tran…
Transitions between patterned states in vegetation models for semi-arid ecosystems
Karna Gowda, Hermann Riecke, Mary Silber
A feature common to many models of vegetation pattern formation in semi-arid ecosystems is a sequence of qualitatively different patterned states, "gaps -> labyrinth -> spots", tha…
