title: Data for: "Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes"

description: R code and data files needed to reproduce the results in Sydenham et al. (2025) Role of forest edges and other seminatural linear landscapefeatures in structuring wild bee habitat connectivity in intensivelymanaged landscapes. The data files contain:

R script.R; R script containing code for running analyses.

Vector files:

TransectSites.shp: spatial lines with location of study sites and a "SiteID" identifier. Lines are 50m and define the transect from which wild bees were sampled

SpatPointSiteIDs.shp: spatial points with location of study sites and a "SiteID" identifier. Points are defined by the centroid of transect lines

csv files:

PlantSite.csv: ";" delimited csv file containing data from vegetation surveys along transects. Surveys were conduced by recording the presensce of plant species within ten one square meter grids. Within each grid plant occurrences were recorded in 16 0.25m by 0.25m subgrids. The csv contains columns



Day = day of survey

Month = month of survey

Year = year of survey

Site_id = site identifier

Flower count = Number of occurrences within subgrids_Number of occurrences within 1m grids along the transect

Comment: Text string explaining the data structure.


ModelMetaComNetDF.csv; comma delimited csv file containing data from wild bee flower-visitation surveys. The bee survey data are from Sydenham et al. (2022) Neutral processes related to regional bee commonness and dispersal distances are important predictors of plant–pollinator networks along gradients of climate and landscape conditions. Ecography, 2022(12), e06379. The data contains multiple columns not used in the attached R script. Columns in the data are:



Site_id = site identifier 

Pollinator_species = bee species identifier

Plant_species = plant species identifier

SitePlant = site plant combination

PlantFreq = local plant abundance 

Occurrence = presence or absence of interaction between bee and plant at site

SitePlantPollinator = site plant bee combination 

PlantDCA1 = plant trait with regards to which pollinators they attract

PlantDCA2 = plant trait with regards to which pollinators they attract  

PlantDCA3 = plant trait with regards to which pollinators they attract

PlantDCA4 = plant trait with regards to which pollinators they attract

meanPlantPhenolgyDay = Peak flowering time of plant, estimated from the peak in interaction frequencies with bees  

BeePhenology = flight time of bees

Eusocial = Sociality of bees

BeeDCA1 = bee trait with regards to which plants they visit    

BeeDCA2 = bee trait with regards to which plants they visit

BeeDCA3 = bee trait with regards to which plants they visit

BeeDCA4 = bee trait with regards to which plants they visit

RegionalCommonness = Regional commonness of bee species 

coords.x2 = latitude coordinates

coords.x1 = latitude coordinates 

ShannonH = Landscape diversity around study site 

bio1 = Annual mean temperature at study site  

DistSnd = Distance to sand deposits from study site
