We emphasize the hierarchical nature of these concepts: higher-level synthetic concepts can be used in the development of theory, whereas lower-level concepts allow more specificity and the formulation of operational definitions. From Wikipedia The habitat is meadows and the ecotone between grass-forb meadows and mixed coniferous forest. Subsequently, we present a conceptual cluster analysis, which facilitates a better understanding of the similarities and differences between boundary and transition concepts. The ecotone is established by elevation increase, temperature decrease at higher elevations, and rainfall (less rain shadow at higher latitudes). Here we examine the history and theoretical baggage of the ecotone, riparian zone, and several other concepts.
Currently, a movement toward conceptual synthesis under the umbrella concept of 'ecological boundary' is underway. Confusion among ecologists and land managers about transition zone concepts and the isolation of studies that use only one transition concept can hinder unified progress in understanding these key systems. There are numerous of living species in the transition region of both ecosystems. Many concepts describing transitional areas have been proposed over the years, such as the prevalent and durable ecotone concept. Ecotone is the bordering region between two communities of the ecosystem. In practice, the definition of what is or is not an ecotone depends on the. Oakland, Calif.: US Department of Agriculture, Western Region, 28 pp.Ecological transition zones are increasingly recognized as systems that play a critical role in controlling or modifying flows of organisms, materials, and energy across landscapes.
