Table A1. Phenological and change over time data for 40 bee species which had 30 or more individuals captured. Seasonality represents the time of year a bee is most active and is calculated as the median Julian date that each species was captured. Phenological breadth, or the length of time a species is active, is the difference between the 10th and 90th percentile of Julian day of capture. Rate of change is a measure of how much the abundance of each species changed from 2014-2019. It is measured as the model coefficient for the linear regression between year and abundance, or the slope of that relationship. Data were standardized so the coefficient represents the change in standard deviation units in abundance per year. P-value is associated with that linear regression. Values with P<0.1 are bolded.
