Disentangling the Effects of Precipitation Amount and Frequency on the Performance of 14 Grassland Species
Fig 1
Soil volumetric moisture content in response to precipitation amount and frequency.
The effects of precipitation amount and frequency on soil volumetric moisture content. There was a significant effect of frequency on soil moisture (F2,48 = 3.45, P = 0.04), with soil moisture decreasing with less frequent precipitation. There was no significant effect of either precipitation amount or the amount × frequency interaction (P>0.10). Points show least-squares mean values and whiskers denote ± 1 SE around the mean.
