Spearman rank correlation tests for associations between salamander encounters and environmental variables at edge 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.bAir temperature as recorded by data loggers on stakes at ACO grids vs. salamander count per sampling occasion.cTemperature as recorded by data loggers under ACOs vs. salamander count per sampling occasion.dAverage percent soil moisture vs. salamander count per sampling occasion.eAverage percent canopy cover vs. mean salamanders per grid per sample period.fAverage depth of leaf litter vs. mean salamanders per grid per sample period.gVolume of downed woody debris (all decay classes) vs. mean salamanders per grid per sample period.hDWD by decay class (1 = little decayed; 5 = well decayed [44]).Spearman rank correlation tests for associations between salamander encounters and environmental variables at edge effect grids.
