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{MurachKindermannHirschletal., author = {Murach, Dieter and Kindermann, Claudia and Hirschl, Bernd and Aretz, Astrid and Schneider, Bernd Uwe and Gr{\"u}newald, Holger and Schultze, Bernd and Quinkenstein, Ansgar and Bilke, Gernod and Muchin, Alexander and Eberts, J{\"o}rg and Grundmann, Philipp and Jochheim, Hubert and Scherzer, J{\"o}rg and Hagemann, Heiko}, title = {Zukunftsrohstoff Dendromasse - Hintergrund und erste Ergebnisse des Verbundforschungsprojekts DENDROM}, series = {Forstarchiv}, journal = {Forstarchiv}, number = {78}, issn = {0300-4112}, pages = {88 -- 94}, language = {de} } @misc{DuemigVesteHagedornetal., author = {D{\"u}mig, Alexander and Veste, Maik and Hagedorn, Frank and Fischer, Thomas and Lange, Philipp and Spr{\"o}te, Roland and K{\"o}gel-Knabner, Ingrid}, title = {Biological soil crusts on initial soils: organic carbon dynamics and chemistry under temperate climatic conditions}, series = {Biogeosciences Discussion}, volume = {10}, journal = {Biogeosciences Discussion}, number = {1}, issn = {1810-6285}, pages = {851 -- 894}, language = {en} } @inproceedings{BensRaabSproeteetal., author = {Bens, Oliver and Raab, Thomas and Spr{\"o}te, Roland and Forman, Steven L. and H{\"u}ttl, Reinhard F.}, title = {Holocene Dune Formation and Human-Induced Aeolian Remobilisation in South Brandenburg, Germany}, series = {AGU 2008 Fall Meeting, Suppl.}, booktitle = {AGU 2008 Fall Meeting, Suppl.}, pages = {H51D-0842}, abstract = {In the Mid Latitudes form and function of the earth surface are mainly affected by Pleistocene periglacial processes such as solifluction, cryoturbation and aeolian deposition. On the other hand, human impact on landscapes in Central Europe may date back to the earliest farmers from the Neolithic Period (c. 5500 a cal BC). At least since the Middle Ages intense land-use produced wide deforested areas. In the sand-rich North German Lowland these human-induced deforestation often resulted in the remobilisation of Late Pleistocene to Early Holocene sand dunes. Especially in the vicinity of former mining sites or glassworks the dune landscapes possess quite young stratigraphic disturbances (fossilized horizons, weak developed top soils). Within the scope of the Transregional Collaborative Research Centre (SFB/TRR) 38, funded by the Deutsche Forschungsgemeinschaft (DFG), inland dunes in South Brandenburg were used as comparison sites to study structures and processes of the initial ecosystem development phase in an artificial water catchment. Here, we present first results of the pedostratigraphy and the age of two dune systems near Glashuette which is about 50 km south of Berlin. Based on twelve Optical Stimulated Luminescence (OSL) and six radiocarbon (14C) datings a chronology of the landscape development for the last c. 10000 years is derived. Data prove that both dune systems - even though they are just c. 1 km apart and have similar morphological features such as height, width, and orientation - have a completely different history in aeolian sand deposition and pedogenesis. At dune 'Glashuette 1' a well established podsol forms the topsoil. At dune 'Glashuette 2' soil development is clearly in a more initial state showing only some humus accumulation and weaker podsolization processes. OSL and 14C ages of sand from 'Glashuette 1' range between about 11.4 ka cal. BC (3.9 m below surface) and 9.4 ka cal. BC (0.7 m below surface). Against that, the sands in 'Glashuette 2' are mainly dated to about 0.8 ka cal BC (3.4 to 0.7 m below surface). On the basis of our findings further analyses can be planned more accurately to study the impact of initial processes on the later state of ecosystems characteristics.}, language = {en} } @misc{SproeteFischerVesteetal., author = {Spr{\"o}te, Roland and Fischer, Thomas and Veste, Maik and Raab, Thomas and Wiehe, Wolfgang and Lange, Philipp and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {Biological topsoil crusts at early successional stages on Quaternary substrates dumped by mining in Brandenburg, NE Germany}, series = {Geomorphologie: relief, processus, environnement}, volume = {16}, journal = {Geomorphologie: relief, processus, environnement}, number = {4}, issn = {1957-777X}, doi = {10.4000/geomorphologie.8083}, pages = {359 -- 370}, abstract = {The influence of biological soil crusts in natural ecosystems on structures and processes is well investigated. However, in South-Brandenburg (Germany), it is possible to study the development of biological soil crusts (BSC) during initial ecosystem genesis on two artificial water catchments with well-known ages and under differing starting conditions. The two experimental sites are located in the recultivation area of the lignite open-cast mining district of southern Brandenburg with a distance of approximately 1 km between them. Two different topographies were constructed at the experimental sites: the experimental plot at the catchment Neuer Lugteich was shaped like a dune, whereas the artificial water catchment H{\"u}hnerwasser was modelled as an inclined slope. The catchment Neuer Lugteich is four years older than H{\"u}hnerwasser. The original substrate at Neuer Lugteich is more sandy and carbonate-free compared to the original substrate dumped at H{\"u}hnerwasser. At both sites geomorphological differentiation and crust development were compared and the importance of substrate-dependent water availability and crust type clarified. Once settled, the crusts influenced the water regime of the soils by delaying infiltration through enhanced water repellency, and by limiting water infiltration. Chlorophyll analysis revealed that all crusts were at early stages of development. At Neuer Lugteich, the establishment of the biological soil crusts was closely associated with the vegetation succession, whereas no clear succession of the crusts could be observed at H{\"u}hnerwasser. The mosaic-like pattern of the biological soils crusts is associated with the distribution of fine-grained material here.zeige weniger}, language = {en} } @misc{DuemigVesteHagedornetal., author = {D{\"u}mig, Alexander and Veste, Maik and Hagedorn, Frank and Fischer, Thomas and Lange, Philipp and Spr{\"o}te, Roland and K{\"o}gel-Knabner, Ingrid}, title = {Organic matter from biological soil crusts induces the initial formation of sandy temperate soils}, series = {Catena}, volume = {122}, journal = {Catena}, doi = {10.1016/j.catena.2014.06.011}, pages = {196 -- 208}, abstract = {Different development stages of algae-dominated and moss-dominated biological soil crusts (BSCs) were sampled on a natural sand dune (b17 years old) and on an experimental sand dune (b8 years old) along a catena, including gradients of vegetation cover, location on the slope, as well as composition and thickness of BSC organisms in northeastern Germany. The accumulation of BSC-derived organic carbon (OC)was determined for bulk materials and fractions less than 63 μm. The OC composition was characterized by solid-state 13C NMR spectroscopy and the carbohydrate-C signature. 14C contents were determined to assess the origin and dynamics of OC. From the radiocarbon contents, two OC pools were differentiated: recent BSC-derived and lignite-derived "old" OC. Downward movement of OC into the underlying substratewas found only undermoss-dominated BSCs at the old sand dune. BSC-derived OC was mainly composed of carbohydrate-C and, to a lesser extent, alkyl C and N-alkyl C, with considerably higher contributions of alkyl C in the young dune, indicating differences in the composition of extracellular polymeric substances produced by the BSCs with age. This is consistent with higher proportions of water-soluble OC of moss-dominated BSCs at the old dune, which is leached in the underlying substrate and initiates soil formation. Because of the channeling effect of mosses, OC depth translocation along with suspended colloidal substances contribute to OC accumulation in substrates.}, language = {en} } @inproceedings{SproeteFischerVesteetal., author = {Spr{\"o}te, Roland and Fischer, Thomas and Veste, Maik and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Hydrophobicity in sandy soils triggered by the development of Scots Pine stands in southern Brandenburg, Germany}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} }
