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} } @inproceedings{BadorreckKruemmelbeinRaab, author = {Badorreck, Annika and Kr{\"u}mmelbein, Julia and Raab, Thomas}, title = {Long-term effects of deep soil loosening on root distribution and soil physical parameters in compacted lignite mine soils}, series = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, booktitle = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @misc{GerwinRaabBauriegeletal., author = {Gerwin, Werner and Raab, Thomas and Bauriegel, Albrecht and Nicolay, Alexander}, title = {Junge B{\"o}den der Niederlausitz}, series = {Brandenburgische Geowissenschaftliche Beitr{\"a}ge}, volume = {22}, journal = {Brandenburgische Geowissenschaftliche Beitr{\"a}ge}, number = {1}, issn = {0947-1995}, pages = {137 -- 148}, abstract = {In der Niederlausitz finden sich sehr unterschiedliche Beispiele f{\"u}r junge Bodenbildungen, die oftmals durch menschliche Eingriffe ausgel{\"o}st wurden.

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} } @inproceedings{BensRaabSproeteetal., author = {Bens, Oliver and Raab, Thomas and Spr{\"o}te, Roland and Forman, Steven L. and H{\"u}ttl, Reinhard F.}, title = {Buried soils and dune sediments as archives of human-induced aeolian activity in the vicinity of historic glassworks, South Brandenburg, Germany}, series = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, booktitle = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {de} } @misc{LeopoldDethierVoelkeletal., author = {Leopold, Matthias and Dethier, David and V{\"o}lkel, J{\"o}rg and Raab, Thomas}, title = {Combining sediment analysis and seismic refraction to describe the structure, thickness and distribution of periglacial slope deposits at Niwot Ridge, Rocky Mountains Front Range, Colorado, USA}, series = {Zeitschrift f{\"u}r Geomorphologie}, volume = {52}, journal = {Zeitschrift f{\"u}r Geomorphologie}, number = {2}, doi = {10.1127/0372-8854/2008/0052S2-0077}, pages = {77 -- 94}, language = {en} } @misc{GerwinRaabBiemeltetal., author = {Gerwin, Werner and Raab, Thomas and Biemelt, Detlef and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {The artificial water catchment "Chicken Creek" as an observatory for critical zone processes and structures}, series = {Hydrology and Earth System Sciences}, volume = {6}, journal = {Hydrology and Earth System Sciences}, number = {2}, issn = {1812-2116}, doi = {10.5194/hessd-6-1769-2009}, pages = {1769 -- 1795}, language = {en} } @misc{GerwinRepmannSchaafetal., author = {Gerwin, Werner and Repmann, Frank and Schaaf, Wolfgang and Raab, Thomas}, title = {Bodenver{\"a}nderungen durch Waldbr{\"a}nde - Stoffvorr{\"a}te und Stoffverlagerungen}, series = {Jahrestagung der DBG 2022 "Grenzen {\"u}berwinden, Skalen {\"u}berschreiten" 5. - 8.

Im Rahmen des auf eine f{\"u}nfj{\"a}hrige Laufzeit ausgelegten Verbundvorhabens finden bodenkundliche Untersuchungen auf zw{\"o}lf Versuchsfl{\"a}chen bei Treuenbrietzen und J{\"u}terbog statt. An beiden Standorten werden unverbrannte Referenzfl{\"a}chen mit einbezogen.

Zudem wurden Mischproben aus dem Ober- und Unterboden entnommen und auf ihren Stoffhaushalt hin analysiert. Auf jeder Untersuchungsfl{\"a}che wurden je drei frei dr{\"a}nende Kleinlysimeter in 10 cm Bodentiefe installiert, um die zeitlichen Ver{\"a}nderungen der Sickerwasserzusammensetzung und die durch den Brand initiierten Stoffaustr{\"a}ge aus dem Oberboden zu quantifizieren.

Dissolution of the cyanide, from Prussian Blue (ferric ferrocyanide), creates an environmental hazard, whereas the risk of groundwater contamination depends on the stability of dissolved iron-cyanide complexes. Lack of a standard leaching method to determine the water-soluble (plant-available) cyanide fraction generates potential limitations for implementing remediation strategies like phytoremediation. Applicability of neutral solution extraction to determine the water-soluble cyanide fraction and the stability of Prussian Blue in surface and near-surface soils of an MGP site in Cottbus, undersaturated and unsaturated water conditions, was studied in column leaching and batch extraction experiments. MGP soils used in the long-term tests varied according to the pH (5.0-7.7) and the total cyanide content (40-1718 mg kg-1). Column leaching, after four months of percolation, still yielded effluent concentrations exceeding the German drinking water limit (> 50 μg L-1) and the solubility of Prussian Blue reported in the literature (< 1 mg L-1) from both alkaline and acidic soils. Long-term (1344 h) extraction of MGP soils with distilled water was sufficient to dissolve 97\% of the total cyanide from the slightly alkaline soils and up to 78\% from the acidic soils. Both experiments revealed that dissolution of ferric ferrocyanide under circum-neutral pH and oxic water conditions is a function of time, where the released amount is dependent on the soil pH and total cyanide content. Unexpectedly high and continuous solubility of Prussian Blue, both in acidic and slightly alkaline MGP soils, implies the need to introduce an additional cyanide fraction ("readily soluble fraction") to improve and specify cyanide leaching methods. Long-term extraction of cyanide-contaminated soil in neutral solution seems to be a promising approach to evaluate the potential hazard of groundwater pollution at the MGP sites.}, language = {en} }
