These data are species lists for each study setting (i.e. MI blueberry, MI Cherry, Oregon, blueberry, and California watermelon). The data present two main pieces of information: (1) species occurrence and abundance & (2) species functional traits. The occurrence of each species is denoted by a '1' for each site type ('EE" = enhanced edge, 'CE' = control edge, 'EC' = enhanced crop, 'CC' = control crop). The column 'Abund' gives to total nujmber of specimens collected across these site types for both years (2015 & 2016). The functional traits are lecty, sociality, nest location and intertegular distance (ITD, a body size metric). The first 3 traits are categorical, their categories are: Lecty - polylectic ('pol') or oligolectic ('oli')Sociality - solitary ('sol'), social ('soc'), or faculatively social ('fac')Nest location - soil, stem, cavity, wood ITD is given in mm. The categorization of these traits follows other published resources (see Methods and Appendices in Nicholson et al 2019 Ecology Letters). For some species traits have not been published and these are given a 'NA' value.
