Trollius transplant performance in the increased temperature, N and snowpack experiment, 2021 - ongoing.
This range expansion experiment was installed in the summer of 2021. We experimentally simulated the range expansion of a subalpine buttercup, Trollius albiflorus, by transplanting six adults into the west edge of the ITEX global change experimental plots, for a total of 288 transplants. To parse apart abiotic and biotic drivers on range expansion, we manipulated half the transplants to ‘reduce below-ground biotic interactions’ using PVC pipe vs ‘control’ biotic conditions where below-ground interactions we left intact. To record above-ground interactions, in 2022-2024 we recorded neighborhood percent cover at the species-level around each Trollius albiflorus transplant using a 10 cm circular hoop. In 2023 and 2024, we quantified soil conditions surrounding each transplant by recording soil moisture (%VWC) and soil temperature (Celsius).

Data from: Selection by pollinators on floral traits in generalized Trollius ranunculoides (Ranunculaceae) along altitudinal gradients
Abundance and visitation of pollinator assemblages tend to decrease with altitude, leading to an increase in pollen limitation. Thus increased competition for pollinators may generate stronger selection on attractive traits of flowers at high elevations and cause floral adaptive evolution. Few studies have related geographically variable selection from pollinators and intraspecific floral differentiation. We investigated the variation of Trollius ranunculoides flowers and its pollinators along an altitudinal gradient on the eastern Qinghai-Tibet Plateau, and measured phenotypic selection by pollinators on floral traits across populations. The results showed significant decline of visitation rate of bees along altitudinal gradients, while flies was unchanged. When fitness is estimated by the visitation rate rather than the seed number per plant, phenotypic selection on the sepal length and width shows a significant correlation between the selection strength and the altitude, with stronger selection at higher altitudes. However, significant decreases in the sepal length and width of T. ranunculoides along the altitudinal gradient did not correspond to stronger selection of pollinators. In contrast to the pollinator visitation, mean annual precipitation negatively affected the sepal length and width, and contributed more to geographical variation in measured floral traits than the visitation rate of pollinators. Therefore, the sepal size may have been influenced by conflicting selection pressures from biotic and abiotic selective agents. This study supports the hypothesis that lower pollinator availability at high altitude can intensify selection on flower attractive traits, but abiotic selection is preventing a response to selection from pollinators.
