This is particularly true for primary succession on homogeneous substrates. However, a mechanistic understanding of spatial colonisation and pattern formation during primary succession has not been achieved yet. Thus, we studied this topic for 7 years within an experimental catchment (6 ha) established in the post-mining landscape of eastern Germany. Equidistant permanent plots (120 plots {\`a} 25m²) allowed for autocorrelation analyses, and thus tracing the spatial development of species cover performance. For each species tested, the "cover balance" first increased due to colonization, while decreasing in the course of succession. Drawing a benefit from these temporal trends, we suggested cover balance levels revealed by autocorrelation analyses to best indicate well-defined phases in primary succession at spatial entities. Hence, with the help of this spatial approach, terrestrial succession can be understood now much better at the most general level of the hierarchy provided by Pickett et al. (1987). In accordance with these authors, at subordinated levels of the causal hierarchy differential species performance might get collectively explained by contributing processes or conditions, such as ecophysiological traits, life history strategies, competition and allelopathy of the occurring plant species. Further research is needed to understand their relative contributions to the pattern formation.}, language = {en} } @misc{SchaafGerwinGruenewaldetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Gr{\"u}newald, Uwe and H{\"u}ttl, Reinhard F. and K{\"o}gel-Knabner, Ingrid and Munch, Jean Charles}, title = {Patterns and processes of initial ecosystem development in an artificial catchment}, language = {en} } @inproceedings{SchaafGerwinVesteetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Veste, Maik and Biemelt, Detlef and H{\"u}ttl, Reinhard F.}, title = {Monitoring program at the artificial catchment "chicken creek", Germany}, language = {en} } @misc{GerwinSchaafBiemeltetal., author = {Gerwin, Werner and Schaaf, Wolfgang and Biemelt, Detlef and Winter, S. and Fischer, Annette and Veste, Maik and H{\"u}ttl, Reinhard F.}, title = {Overview and first results of ecological monitoring at the artificial watershed Chicken Creek (Germany)}, series = {Physics and Chemistry of the Earth}, volume = {36}, journal = {Physics and Chemistry of the Earth}, number = {1-4}, issn = {1873-5193}, pages = {61 -- 73}, language = {en} } @misc{RaabKruemmelbeinSchneideretal., author = {Raab, Thomas and Kr{\"u}mmelbein, Julia and Schneider, Anna and Gerwin, Werner and Maurer, Thomas and Naeth, M.

The two largest districts are located in geographically opposite regions: The Rhineland in the western part and Lusatia in the east of Germany. As particularly these two mining districts will experience severe changes in their socioeconomic as well environmental conditions, the federal government has adopted comprehensive economic support measures. However, the environmental changes will also cause altered ecosystem functions and services to be provided by the future post-mining landscapes. Results In this paper, the two main lignite-producing regions of Germany are compared with regard to their natural and cultural settings. The economic situation and its history are reflected and differences are outlined. Part of the disparities in the cultural development can be explained by very different natural conditions, especially edaphic factors and climatic situation. Because of dissimilar geological settings, different mining technologies were developed and are in use in the two regions with distinct effects on the resulting post-mining landscapes. Conclusion The long-standing and manifold lignite mining activities have radically restructured the landscapes in Lusatia and the Rhineland. With the ongoing decline of the mining industry and its complete cessation, presumably within the next decade, both regions will alter their faces significantly. These changes offer both challenges but also opportunities with respect to the post-mining landscapes and their ecosystem services they are going to provide. The prerequisites for a positive socioeconomic development and for sustainable land-use concepts that also consider ecological aspects are different for both regions. However, or especially because of these differences, the knowledge exchange and experience transfer between both mining regions are pivotal for the success of this extensive transformation process.}, language = {en} } @misc{JouySchueleAdhikarietal., author = {Jouy, Florent and Sch{\"u}le, Maren and Adhikari, Yojana and Binder, Anja and Clerc, Danica and Gerwin, Werner and Heinken, Thilo and Raab, Thomas and Repmann, Frank and R{\"o}nnefarth, Susanne and Schirrmacher, Marina and Schmehl, Marie-Therese and Schr{\"o}der, Jens and Ibisch, Pierre L.}, title = {Factors impacting the variability of post-fire forest regeneration in central European pine plantations}, series = {Restoration Ecology}, journal = {Restoration Ecology}, doi = {10.1111/rec.70017}, abstract = {Fire is increasingly posing a risk to forests and plantations, even in the temperate latitudes of central Europe. Little is known about fire ecology in this region, and therefore, appropriate approaches for the management and reforestation of burned sites are mostly lacking. In a Scots pine plantation region in Brandenburg (northeast Germany), the early tree regeneration of two nearby areas that burned 1 year apart was investigated. We observed that 3 years after the fire events, the forest in one study area showed a relatively high regeneration with a mean density of 7765 saplings/ha, clearly dominated by European aspen (93\%); whereas the other study area showed a lower mean density of 5061 saplings/ha, dominated by Scots pine (71\%) and aspen (15\%). Three years after the fires, the difference in aspen density was 11-fold between the two areas. We studied the effects of several variables about soil and environmental properties on the aspen establishment in these two study areas in the second and third years after the fire events. We found that the post-fire aspen regeneration was influenced by several factors, including soil texture, soil disturbance from forest management, volume of deadwood, and browsing. We also discussed that weather conditions during seed production and germination might have played a role in the difference in aspen establishment between the two study areas. We concluded that the post-fire forest regeneration potential in the study region is highly variable and could come under critical pressure as climate change progresses.}, language = {en} } @misc{RaabHinzGerwinetal., author = {Raab, Thomas and Hinz, Christoph and Gerwin, Werner and Lehmkuhl, Frank}, title = {Editorial for the Special Issue "Anthropogenic Geomorphology - Geomorphology in the Anthropocene"}, series = {Geomorphology}, volume = {422}, journal = {Geomorphology}, issn = {0169-555X}, doi = {10.1016/j.geomorph.2022.108528}, language = {en} } @incollection{Gerwin, author = {Gerwin, Werner}, title = {Bodenkundliche Beobachtungen auf dem D{\"o}ttenbichl bei Oberammergau}, series = {Der sp{\"a}tlat{\`e}ne- und fr{\"u}hkaiserzeitliche Opferplatz auf dem D{\"o}ttenbichl s{\"u}dlich von Oberammergau}, booktitle = {Der sp{\"a}tlat{\`e}ne- und fr{\"u}hkaiserzeitliche Opferplatz auf dem D{\"o}ttenbichl s{\"u}dlich von Oberammergau}, editor = {Zanier, Werner}, publisher = {C.
