Fig. 3. Relative elevation, soil N₂O flux, and local wavelet spectrum for seeded-grass transect, 29 Apr. 2004. Convex (CX), concave (CV), cultivated wetland (CW), and uncultivated wetland (UW) landscape elements are indicated. Color bar is log of wavelet variance. Scales <30 m are not significant according to a permutation test (p < 0.05).
