Identifying interspecific associations is very important for understanding the community assembly process. However, most methods provide only an average association and assume that the association strength does not vary along the environmental gradient or with time. The scale effects are generally ignored. We integrated the idea of wavelet and network topological analysis to provide a novel way to detect nonrandom species asso...

Aim To evaluate how a biotic filter (overstorey cover [ OC ]) shapes an elevational herb richness pattern and to test whether intermediate elevations represent more suitable habitats for herb species due to the minimal biotic and moderate abiotic filtering that occured there. Location Dongling Mountain, China. Taxon Herbs. Methods We sampled herb richness along a 1,000‐m vertical transect ( OC and elevation covary) and four ho...
