Edaphic interslope and valley bottom differences at Evolution Canyon, lower Nahal Oren, Mount Carmel, Israel


The opposite slopes of lower Nahal Oren, Mount Carmel, designated Evolution Canyon display physical and biotic contrasts, although both are cut in Upper Cenomanian calcareous limestone. The three-fold greater solar radiation makes the south-facing slope warmer, drier and more variable than the north-facing slope and valley bottom. Consequently, biodiversity is greater. Differences in soil morphology, moisture regime and microfabric between the north- and south-facing soils suggest that they belong to different taxonomic classes. These differences probably result in part from the forested ecosystem of the north-facing slope versus the savanna-like ecosystem of the opposite slope
