Complex Responses to Global Change at Alpine Treeline. Malanson, G. P. 22(4):333–342. ![Complex Responses to Global Change at Alpine Treeline [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex A focus of geography is the study of complexity: we include many interacting processes when we study places. Another view of complexity in geography is that complex pattern, in particular spatial pattern, can arise from few or simple interactions, if they are nonlinear. Environmental responses to global change are likely to be nonlinear and thus complex. Shifts in ecotones-the boundaries of vegetation types or biomes-may be indicative of such complex response to global change. One reason for expecting nonlinearity is that positive feedbacks may play a strong role in determining the conditions for the establishment and growth of trees. A spatially explicit computer simulation is used to examine the effects of feedback strength, seed rain and establishment, and rate of environmental change as might occur at a mountain treeline ecotone. Changes in presence and abundance of trees exhibit nonlinear responses to environmental change during a transient period. The implications of nonlinear responses are that surprises are more likely than precise prediction.
