Extended Data Fig. 7: Relationships among temporal trends in α diversity metrics.
From: No net insect abundance and diversity declines across US Long Term Ecological Research sites
Dots represent the change over time of a diversity metric at an LTER site. Species evenness was calculated as Pielou’s Evenness Index, and dominance represents the proportional frequency of the most abundant taxon. Light gray lines divide each plot into quadrants to help visualize sites where the sign of change in diversity metrics was similar (top right, bottom left) or opposite (top left, bottom right). Black dashes denote the line of best fit. Slopes are significant at the α = 5% level, R2 = 0.36 for evenness vs. richness, and R2 = 0.68 for evenness vs. dominance.
