Studying reproductive strategies of plants is an important topic of research in evolutionary ecology, bringing essential knowledge on their adaptation and diversification (Barrett 2010), as well as on the ecosystem functioning, with potential applications in biodiversity conservation and crop breeding. Pollination, which allows the transfer of pollen from the anther to the stigma of flowering plants, is a central evolutionary process given its importance in the dispersal of genes and their assortment among individuals of a species. Pollen may be dispersed by abiotic factors (i.e. wind or water), but biotic dispersal through interactions with insects (in at least two-thirds of cases) is more commonly involved (Ollerton et al. 2011; Willmer 2011). A variety of questions have thus been tackled in pollination biologies, such as floral traits as signals for pollinators, the evolution of pollination syndromes, the specificity of plant-pollinator interactions, and the reconstruction of pollination networks (Baguette et al. 2020; Johnson and Steiner 2000; Willmer 2011; Phillips et al. 2020).
