Extended Data Fig. 3: Starting population sizes of time series added to the Living Planet Index have declined between 1950 and 2015.

From: Random population fluctuations bias the Living Planet Index

Extended Data Fig. 3

Each point is the initial population size of a time series for the first year in which it was monitored. The red line is the linear regression of the natural logarithm of population sizes through time. The vertical axis is ln-scaled.
