- Boundaries are the most reactive nodes in landscapes and may be hypersensitive to global change in climate and land use.
- An MSc study by UCT student Rua Osman looked at the combination of soil and vegetation boundaries within Tankwa Karoo National Park along a altitudinal gradient
- She and her colleagues investigated the abruptness of four soil-vegetation boundaries separating eight communities and classified them as gradual, sharp or non-existent.
- Soil respiration and perhaps other ecosystem processes were mediated by the soil-vegetation boundaries.
- These nodes should be the focus of ecological studies since they reveal much more than the constituent patches themselves.
