Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant <em>Veratrum grandiflorum</em>

Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual’s resource pools, from unpollinated flowers and inflorescences. Despite this, studies that evaluate the effect of resource reallocation simultaneously across different modular levels of an individual remain rare, especially in alpine plants. Here, we estimated pollen limitation at three modular levels (i.e., flower, raceme, and whole plant) in the perennial alpine herb Veratrum grandiflorum (Maxim. Ex Baker) Loes in the eastern Himalayan Hengduan Mountains. We used fruit set and seed production as two proxies for female reproductive success. Based on seed production, we found that pollen limitation differed significantly among modular levels, wi..., , # Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant *Veratrum grandiflorum* We have submitted our raw data (**pollen.limitation_Data.csv**), derived data (**Fruit_Seed_Data.csv**), and R script (**pollen.limitation_Script.R**). ## Descriptions **pollen.limitation_Data.csv**: at the whole-plant level, we collected data based on racemes from the base to top. so, the dataset includes the number of hermaphroditic flowers and fruits corresponding to each raceme. However, at the raceme level and flower level, data were not collected for every raceme. 1.Number of variables: 8 2.Number of cases/rows: 129 individuals 3.Variable List: *a) Individual*: individual identity *b) Pollination*: to which of the two treatments subjected, natural pollination (Natural) or pollen supplementation (Hand) *c) Level*: to which of the three levels subjected, whole_plant level (Individual), Raceme level (Inflorescence) or flower level (Flower...,
