Extended Data Fig. 1: Minimum set analysis on a subsample of the data in which 30 individuals were randomly drawn each different date within a site-year.
From: Greater bee diversity is needed to maintain crop pollination over time
We compared the results (dashed blue line) to a null model (solid red line) in which subsamples of 30 individuals were all drawn from the same date. Shaded areas represent the 95% confidence intervals across 100 replicates of the sampling process. Each point represents the mean across all replicates for a single site-year. The difference between the endpoints of the observed and null accumulation curves represents the increase in the minimum set that is due to turnover across days within a year.
