Note that plant-pollinator interaction data within this database were not sampled in the frame of this study but were derived from 30 individual data sets of plant-pollinator interaction networks from published or unpublished studies. These studies were conducted across several sites in 9 countries, ranging from tropical to arctic regions but with the majority of sites being located in temperate regions. In all data sets, species correspond to either taxonomic species or morphospecies, and each recorded interaction corresponds to an observation of an animal visiting a flower. We usually used the same sites that were described by the original studies except when the original sites represented relatively small observational plots or were observed for only part of a day. Specifically, we pooled the original sites if they were less than ~6 km apart from each other, harbored similar plant communities, and if a reasonably large proportion of them were sampled on each sampling day. We also standardized southern hemisphere dates by adding 182 days to each sampling date for each site in the southern hemisphere (affecting studies Chacoff2018, Kaiser-Bunbury2017, and Vazquez2003) to assure that the whole flowering season takes place within one single calendar year. Thus, this database may partly differ from the original data sets in terms of site classification and sampling date.
For usage of the data we recommend to refer to the related studies and, wherever possible, to use the originally published data, which may provide more metadata and relevant information. In any case, if you make use of this database or part of it, please cite the related studies and data publications (listed in file OIK-07303_original_studies.xlsx).
OIK-07303_database.csv – data set containing plant-pollinator interaction data from 30 studies. For some studies code identifiers instead of species names are used for plant (column lower) and pollinator (column higher) species.
OIK-07303_original_studies.xlsx – table containing references (DOI or URL) to articles and data publications related to the data compiled in OIK-07303_database.csv.
OIK-07303_results.csv – data frame that was finally used for statistical analyses. For each aggregated network (rows) various network indices and co-variables (columns) are given.
OIK-07303_functions.R – R script containing functions that allow aggregating interaction data into networks at different temporal scales and calculating network indices and various co-variables.
OIK-07303_betalinkr.R – R script containing function betalinkr to assess species turnover and link rewiring.
OIK-07303_network_aggregation.R – R script to prepare the data from OIK-07303_database.csv for aggregating networks and to calculate network indices and co-variables, which results in a data frame identical to OIK-07303_results.csv.
