Spearman rank correlation tests for associations between salamander encounters and environmental variables at harvest effect grids.

Tests were conducted for counts of eastern red-backed (Plethodon cinereus), northern zigzag (P. dorsalis), and northern slimy (P. glutinosus) salamanders.*Significant effect at α = 0.05.aPrecipitation 48 hours prior to sampling vs. mean salamanders per grid per sampling day (treatment types and sample periods pooled).bAverage daily air temperature vs. mean salamanders per sampling occasion during the pre-harvest period (treatment types pooled).cAverage daily air temperature vs. mean salamanders per sampling occasion during the post-harvest period where canopy was retained (control, clearcut adjacent, shelterwood, and shelterwood adjacent).dAverage daily air temperature vs. mean salamanders per sampling occasion during the post-harvest period where canopy was removed (clearcuts and group cuts).eVolume of downed woody debris (all decay classes) at each grid vs. mean salamanders per grid per sample period (treatment types pooled).fDWD by decay class (1 = little decayed; 5 = well decayed [44]); data from 2010 and 2011 only.Spearman rank correlation tests for associations between salamander encounters and environmental variables at harvest effect grids.
