Description :
This research addresses the issue of scale-dependence, focusing on spatial correspondence of floristic and edaphic gradients across salt marsh creeks at Skallingen, Denmark. The AA. employed a hierarchical approach, which compared vegetation and soil gradients at both fine and coarse scales. They found poor correlations between vegetation and soil at the fine scale but an improved correspondence at the coarse scale. Therefore this research accommodates the importance of both biological and environmental components by explicitly emphasizing their simultaneous significance, each perceived at different spatial scales. The AA. conclude that the concept of scale-dependence might serve as an efficient conceptual framework in salt marsh biogeography.
