Backward stepwise regression indicated three highly significant climatic Bioclim variables ( table 2 ), annual mean temperature ( p = 0.0020), annual precipitation ( p = 0.0047), and precipitation of wettest quarter ( p = 0.0063); and three marginally significant Bioclim variables, isothermality ( p = 0.0438), annual temperature range ( p = 0.0458), and mean annual diurnal range ( p = 0.0484). 4.
