a Cartoon describing spatial kernels as identified in arid ecological systems. The growth of a focal individual (black arrow) can be influenced by its surrounding environment. b Cartoon depicting a spatial kernel framework in a microbial CFU experiment. Black arrow indicates focal colony. c Model selection results, quantified by the Akaike Information Criterion (AIC). Each point on the curve represents the AIC of a model created with data at the timepoint specified. The features in the model include colony-centric features (see e) and all annuli proceeding outward from the focal colony up to and including the distance indicated along the x-axis. The minimum AIC is marked (black arrow). d Distance corresponding with the best regression model (global minimum AIC) at each timepoint. e Intercept and focal colony coefficient values fitted independently at three timepoints. f Spatial-temporal kernel models. Each ecological kernel is fitted independently at the designated timepoint.
