| Description: |
Reproductive and floral traits are strikingly diverse in angiosperms. However, general patterns in how these traits are associated and how these associations shape species diversity are still poorly known. To date, major trait associations, or plant ecological strategies, have largely been described using vegetative traits and are underpinned by size and growth. However, these do not consider traits relating to pollination, mating and sexual systems, which are critical to species’ reproductive success. Here, we characterize the strategies plants have evolved to achieve reproduction using 21 traits from an original set of 360 species sampled in 259 families across the angiosperm phylogeny. While outcrossing rates were associated with a well-known trait axis involving plant size and growth form, we revealed that pollination-related traits, including flower sex and floral reward, contribute to an equally important axis of variation. Surprisingly, this pollination axis clearly sets species with unisexual flowers apart from those with bisexual flowers, likely the result of selection for sexual specialisation at the flower and individual levels. Three angiosperm-scale reproductive strategies emerged, all containing considerable diversity that cannot be easily reduced, in contrast to strategies derived from vegetative traits. Our study demonstrates that often-overlooked, pollination-related traits represent an important dimension of plant trait variation that provides new insights into the ecology and evolution of mating and sexual systems. The reproductive strategies outlined here are the result of long-term evolutionary processes and ecological interactions between plants and pollinators, highlighting the importance of considering both fields when disentangling the origins of reproductive diversity. Significance statement Flowering plants (angiosperms) possess a spectacular diversity of flower morphologies, colours, modes of pollination and systems of reproduction. These traits are known to have evolved together ... |
