title: Data from: GloPL, a global data base on pollen limitation of plant reproduction

description: Plant reproduction relies on transfer of pollen from anthers to stigmas,
 and the majority of flowering plants depend on biotic or abiotic agents
 for this transfer. A key metric for characterizing if pollen receipt is
 insufficient for reproduction is pollen limitation, which is assessed by
 pollen supplementation experiments. In a pollen supplementation
 experiment, fruit or seed production by flowers exposed to natural
 pollination is compared to that following hand pollination either by
 pollen supplementation (i.e. manual outcross pollen addition without
 bagging) or manual outcrossing of bagged flowers, which excludes natural
 pollination. The GloPL database brings together data from 2969 unique
 pollen supplementation experiments reported in 927 publications published
 from 1981 to 2015, allowing assessment of the strength and variability of
 pollen limitation in 1265 wild plant species across all biomes and
 geographic regions globally. The GloPL database will be updated and
 curated with the aim of enabling the continued study of pollen limitation
 in natural ecosystems and highlighting signiﬁcant gaps in our
 understanding of pollen limitation.
description: GloPL, a global data
 base on pollen limitation of plant reproductionThe GloPL database
 brings together data from 2969 unique pollen supplementation experiments
 reported in 927 publications, allowing assessment of the strength and
 variability of pollen limitation in 1265 wild plant species across all
 biomes and geographic regions globally. A case is defined as a comparison
 of the reproductive output (proportion of ﬂowers setting fruit, proportion
 seeds per ovule, seeds per fruit, seeds per flower, seeds per plant) of
 plants receiving hand pollination with those receiving natural
 pollination. When studies were replicated across sites and/or years at the
 same site, each unique site and year combination became one case in the
 dataset. We treated each year and population as a separate data case
 (i.e., row in the database), as were time periods within a season or
 multiple morphs (e.g., flower color, gender) within a population and
 different experimental treatments (e.g., nutrient addition, herbivore
 exclusion). For each case within the GloPL database, we provide plant
 taxonomic information and geographic coordinates. Detailed meta-data for
 each column is located in Table 2 of the Data Descriptor
