英文摘要

Stream research has contributed only modestly to general ecological theory. Moreover, the rate of generation of new ideas in stream ecology may have slowed recently. These shortcomings might be remedied by a more deliberate effort to generate new, creative ideas about streams that will enhance their use in developing general theory. The creative process has been thoroughly studied by psychologists and, while the field is still in flux, most cognitive psychologists agree that juxtaposition of disparate concepts or observations can stimulate new ideas. How this technique might enhance stream ecology is illustrated with an analogy between functional morphology and stream ecology. Definition of form and function in streams is required to develop this analogy and a hierarchical, scale-dependent approach is essential. The effect of structure and configuration of stream channels on their functioning is a promising research area that can be applied at several scales. Parallels with landscape ecology are strong. Extending this analogy to larger scales reminds us that streams are, in essence, branched systems; however, little research has been done on the ecological consequences of branching patterns in streams and rivers. Combination of this branched image with other surface and subsurface water bodies leads to an even broader view of streams as planar systems, intimately connecting terrestrial and aquatic ecosystems along flowpaths. This exploration of ideas about stream shape and its functional consequences suggests several opportunities for stream ecology to contribute to general ecological theory. More importantly, this effort suggests that the process of idea generation is straightforward, accessible, and beneficial for both science and scientist.
