Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains
Oikos, EarlyView.Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.
