The distribution of studies across time and temporal study design. All y-axes show a count of studies. A shows study publication year and B the first year when both plant and herbivore elements were measured. C shows the temporal extent of the studies, defined as the number of years when both plant and herbivore elements were measured. Note that the studies with temporal extent longer than 1000 years come from one modeling study. D shows the temporal resolution of the studies, defined as the interval between measurements of the outcome (plant), if regularly measured or not and for how long. Sample size refers to studies for which the variable was feasible to assign
