Scale dependency in native-exotic richness relationships revisited

In their seminal paper, Shea and Chesson (Trends in Ecology & Evolution, 2002, 17, 170) developed a highly cited model (S&C model) showing scale dependency in the native-exotic richness relationships. Two decades later, extensive additional data have been accumulated, leading to new findings and insights. Accordingly, two updates were made here to the original S&C model: (1) changing the negative richness relationship between natives and exotics to non-consistent or non-significant; and (2) modifying the original diagram to correctly represent native and exotic species richness and their correlations across both small and large scales.

Automated summary

In their influential paper, Shea and Chesson proposed a model (S&C model) to explore the scale dependency in the relationships between native and exotic species richness. Two updates were made in this study based on extensive new data: (1) changing the negative richness relationship between natives and exotics to non-consistent or non-significant; and (2) modifying the original diagram to accurately represent the richness and correlations of native and exotic species across different scales.
