1 INTRODUCTION In the intricate tapestry of nature, no species exists in isolation; organisms are embedded in a complex web of interactions on which they depend for survival and reproduction. In animal-pollinated plants, successful pollination often depends on the fit between floral traits and the morphology of their pollinators (Bartomeus et al., 2016; Kritsky, 1991; Leimberger et al., 2022).

Editor’s summary Theory predicts that areas of the globe with higher energy (warmer or more productive areas) will have a higher number of species. Empirical studies have found mixed support for this hypothesis, likely because other factors also influence geographical species richness patterns. Coelho et al. used an alternative approach to isolate the effects of climate on biodiversity by comparing vertebrate species richness across climate bins.
