Environmental change drivers (ECDs) impact ecological communities in various ways, from enrichment that increases species' performance and abundance, to stressors that reduce their reproduction and growth. These effects can affect species coexistence as well as impact ecosystem functioning and the relationship between biodiversity and ecosystem function (BEF). Predicting the impact of ECDs on communities and BEF relationships requires understanding how ECDs affect fundamental population parameters, including intrinsic rate of increase (r), carrying capacity (K), and interspecific interactions (
