(A) Moran effects occur when populations in distinct spatial locations experience similar environmental factors, for example prevailing weather conditions. (B) This can lead to some level of synchrony among populations being sampled at different sites. Each point in C shows the mean and variance across the six sampling sites at one of the 11 census times shown by vertical dotted lines in B. Spatial Taylor’s law says that a plot of log(mean) against log(variance) of population density is approximately linear. Reuman et al. (1) show that synchrony typically preserves the approximately linear relation but reduces the slope of TL.
