Global epistasis on fitness landscapes
Juan Diaz-Colunga, Abigail Skwara, Karna Gowda +4
Epistatic interactions between mutations add substantial complexity to adaptive landscapes, and are often thought of as detrimental to our ability to predict evolution. Yet, patter…
An ensemble approach to the structure-function problem in microbial communities
Chandana Gopalakrishnappa, Karna Gowda, Kaumudi Prabhakara +1
The metabolic activity of microbes has played an essential role in the evolution and persistence of life on Earth. Microbial metabolism plays a primary role in the flow of carbon,…
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…
