英文摘要 | Explaining nature's biodiversity is a key challenge for science. To persist, populations must be able to grow faster when rare, a feature called negative frequency dependence and quantified as 'niche differences' (N) in modern coexistence theory. Here, we first show that available definitions of N differ in how N link to species interactions, are difficult to interpret and often apply to specific community types only. We then present a new definition of N that is intuitive and applicable to a broader set of (modelled and empirical) communities than is currently the case, filling a main gap in the literature. Given N, we also redefine fitness differences (F) and illustrate how N and F determine coexistence. Finally, we demonstrate how to apply our definitions to theoretical models and experimental data, and provide ideas on how they can facilitate comparison and synthesis in community ecology. |
