Title Visitation rates of bee groups in videos in 2014
Downloaded 3 times
Description Visitation rates collected by in total 54 hours of video recording in 18 fields in 2014. Open Office Org Calc was used to create this data file. "no.visits" = number of visits by the corresponding species groups, "species" = species group {"bumble" = Bombus terrestris, B. lucorum, B. lapidarium; "halictid" = several Halictidae, mainly Lasioglossum species; "honey" = Apis mellifera}, "start.time" = starting time of the video at three different time periods (7:00 am, 8:30 am, 10:00 am).

Title Handling time of bee individuals (video data) in 2014
Downloaded 3 times
Description Handling time of the 2100 bee individuals are derived from the videos recorded in 18 fields in 2014. Open Office org Calc was used to create the data file. Abbreviations: "species" = three different bee species groups ("bumble" = Bombus terrestris, B. lucorum, B. lapidarius; "halictid" = several Halictidae species, mainly Lasioglossum species; "honey" = Apis mellifera), "handling.time.s" = total time bees spent handling the flower in seconds, "nectar.time.s" = total time bees spent on/at the stigma and feeding nectar, "group.halictid" = halictid species were divided into two size classes (length ~ 6 mm or ~ 8 mm), "successful.visit" = visit, where stigma was touched = nectar.time.s > 0; "start.time" = starting time of the video divided into three time periods (7:00 am, 8:30 am, 10:00 am).

Title Pollen-yield experiment data from 2014 and 2015
Downloaded 3 times
Description Data from hand-pollination experiments in fields with different levels of pollen deposition in 2014 (5 levels) and in 2015 (7 levels). Details see manuscript and Table S1 in the supplementary material. Open Office Calc used to create this file. Abbreviations: "harvestable" = 1, if pumpkin fruits could be harvested, "marketable" = 1, if pumpkin fruits weigh more than 800 g.
