Tab - Overwintering Data Column * Yard - Each of the 8 yards used in the study * Colony ID – individual colonies used in the study * Treatment – the covered (called wrapped) or control (called unwrapped) treatments * Date – sample dates for each inspection * Survival – Whether a colony was dead or alive at an inspections. 0= alive, 1= dead * Raw mass (kg) – the mass of each colony in kg which was calculated by weighing each side 3 times with the crane scale, averaging the three weights per side, and taking a sum. * Percent change in mass over time – change in mass at each time point compared to Nov 9th (considered time point zero). * Linear equation for growth – calculated by plotting the raw mass over time in excel and then displaying the linear equation. * Rate of growth (Mx) – by taking the Mx out of the linear equation from above (y=Mx+b) * Arboreal cover within 100m radius – calculated as described in methods. * Proportion mid-winter feed consumed with dead colonies filtered – we removed the proportion feed consumed for colonies that died over the winter. Overall proportion was calculated by taking the raw mass minus the mass of the cover board that was removed on Feb 2 when the feed was added. We then added the mass of the inserted feeder board which was 0.6kg. proportion was calculated in kg * Proportion emergency feed consumed, all colonies – same as above with the dead colonies included. Calculated in kg. * Frame sides of bees – calculated following methods from Delaplane et al 2013. Only calculated on 3/30/2021 and 4/12/2021 * Queen sign – if we saw the queen or sign of the queen (eggs or young larvae) we assigned a y, if no sign was seen we assigned a n. Only measured on 3/3/2021 and 4/12/2021 * Brood area (cm2) – the sum of the brood calculated as in the methods for each frame within a colony. Tab – Preoverwintering Mites Column: * Yard: Colony: Treatment- as described above * October mites – mites levels in colonies from a 300 bee alcohol wash which was taken on October 5-8th 2020. * November mites – mite levels in colonies from a 300 bee alcohol was which was taken on Nov 9th 2020. Tab – Colony Temperatures Column: * Yard: Colony: Treatment – same as above * Average temp – the average of each temperature taken every 256 minutes over the course of a calendar week. * Calendar week * sent-vs-live – sentinel are colonies that did not have live bees in them but were actually just empty colonies with a temperature monitor in them to calculate ambient temps. Live were target colonies within the experiment that were alive. * Log25- is the log transformation of the average temperature plus 25. LN(averagetemp+25) Tab – tipping scale side experiment Column: * Colony- colonies used to in experiment that were located at Iowa State University during the summer 2019. * Tilted left – the weight of the left side of the colony using the tilt scale from this experiment in kg. * Tilted right – the weight of the right side of the colony using the scale from this experiment in kg. * Tilted total – the sum of the weight from the two sides in kg. * Classic scale weight – the weight in kg of colonies as measured on a postal scale following methods from Dolezal et al 2019.
