Optimising daily sampling of plant–bee interaction networks

open access: yesJournal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...
