Understanding these interactions is especially relevant because abiotic and biotic environmental components respond differently to various drivers of global change. Here, we aim to understand whether the effects of pollination (biotic component) on plant reproduction depend on soil moisture (abiotic component), two factors known to affect plant reproduction and that are changing with global change.<h4>Methods</h4>We conducted pollen supplementation experiments for two plant species, Delphinium nuttallianum and Hydrophyllum fendleri, in subalpine meadows in the Western USA across 4 years that varied in soil moisAnnals of botanyDoes pollination interact with the abiotic environment to affect plant reproduction?PMC11805941DEB 1754518Iler AMRodelius IBfalseDoes pollination interact with the abiotic environment to affect plant reproduction?<h4>Background and aims</h4>Abiotic and biotic components of the environment both limit plant reproduction, but how they interact with one another in combination is less understood.
