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.
