Fig. 5. Relative elevation, soil N2O flux, and local wavelet spectrum for seeded-grass transect, 23 June 2004. Convex (CX), concave (CV), cultivated wetland (CW), and uncultivated wetland (UW) landscape elements are indicated. Color bar is log of wavelet variance. All scales are not significant according to a permutation test (p < 0.05).
