had a truly unifying general theory of ecological succession. All that was needed - we thought - were data clarifying a few controversial issues. This is how our studies of old-field succession began in 1973. We viewed old-fields as a sort of ‘Drosophila‘ for terrestrial ecology.978-94-010-7603-6978-94-009-2444-4作者: drusen 時間: 2025-3-24 06:16 作者: Middle-Ear 時間: 2025-3-24 08:29 作者: 蕁麻 時間: 2025-3-24 11:13
Selected ecosystem processes and functions,Alterations in the biotic components of the ecosystem under study were largely described in Chapter 4. In this Chapter, we focus on some important ecosystem processes and functions, particularly characteristics of nutrient cycling and energy flow. Results presented here form the basis for more general ecological interpretations in Chapter 7.2.作者: separate 時間: 2025-3-24 16:40

Introduction,losely related to the general trends in ecology. These trends were thoroughly reviewed recently (O’Neil et al. 1986, Austin 1986, Noy Meir and van der Maarel 1987, Keddy 1987, Tilman 1988). It was clearly shown that (1) ecosystems should be considered as complex hierarchical systems, (2) each hierar作者: 捏造 時間: 2025-3-25 07:30
General characteristics of the region,wer Palaeozoic (Silurian and Devonian) sedimentation basin known worldwide in geological literature under the name Barrandien (after a French paleontologist Joachim Barrande who studied this region from 1830–1870).

Dynamics of populations and communities,basic successional seres, i.e., xeric and mesic, viewed through differences in vegetation.

Reaction to perturbations,ommunity stability. It may be shown . that some structural features are correlated with aspects of stability, but so far, we have no theoretical reason to consider any structural feature to be an . sign of stability (see e.g. Goodman 1975). Similarly, the perturbation experiments seem to be the best作者: 加花粗鄙人 時間: 2025-3-26 04:04
Synthesis,e relation to investigations of succession itself, stability, productivity, and nutrient balance of ecosystems were often studied. Thus, we can try to compare our conclusions with former and newly emerged theories focusing on common trends in succession.作者: 傾聽 時間: 2025-3-26 07:11
Summary,ca. fifty years of succession in both studied seres. Some conclusions are simplified, since they were often inferred from a simple comparison of young (X1, X2, and M1, M2) and old (X3 and M3) fields. Many characteristics have not changed unidirectionally during the whole period under consideration. 作者: Cuisine 時間: 2025-3-26 10:42 作者: GULLY 時間: 2025-3-26 13:26
Reaction to perturbations, way (if not the only one) to recognize the functional relationships within the community. In order to evaluate the stability and to get better insight into functional relationships within the community, we conducted a set of perturbation experiments.作者: LUT 時間: 2025-3-26 20:19
Dynamics of populations and communities,tinuous transitions between those seres which were only sporadically analysed in detail; other fields also existed that were drier and wetter than those selected for intensive study in the xeric and mesic seres, respectively. This must be considered in all other interpretations and generalizations.作者: ALLEY 時間: 2025-3-26 21:31
Summary, (X1, X2, and M1, M2) and old (X3 and M3) fields. Many characteristics have not changed unidirectionally during the whole period under consideration. Despite that, such concentrated information gives a good overview of the succession studied, and of the contents of this book as well.作者: 思想流動 時間: 2025-3-27 01:42 作者: 技術(shù) 時間: 2025-3-27 06:24
Introduction,ible only when combining various approaches. Most historical controversies (like individualistic vs. organismal concepts of plant communities) may be viewed as approaches emphasizing a particular hierarchical level. In our study, we combine the population-community approach and the functional ecosystem approach, as defined by O’Neil et al. 1986.作者: stroke 時間: 2025-3-27 10:37 作者: anticipate 時間: 2025-3-27 17:02
Abandoned fields in the region,ulture in the region, respectively). Most of these 27 to 40 year-old abandoned fields represented places of very unfavourable conditions for modern agriculture. Being too small, on steep slopes or on margins of rocky river terraces with only a shallow layer of soil they could not be included into systems of large-scale cultivation.作者: 隱士 時間: 2025-3-27 21:39
