Figure 1
Relationships between monthly averages of measured δprecip and δhair_measured. Crosses (grazing season) and circles (stall season) represent the multi-year averages for each specific month when the cow was entirely either in stall or on pasture (90 and 97 hair data and 53 and 27 precipitation data in grazing season and stall season, respectively). The R2 of the linear regressions are 0.87 (p < 0.01) and 0.13 (p = 0.38), respectively in grazing and stall seasons, and 0.65 (p < 0.01) when taken together. Error bars denote standard deviations. Note that for simplification the horizontal error bar represents only the average of the monthly standard deviations.
