We determined the concentration, chemical composition, radiocarbon age, and bioavailability of DOC along the hydrological flow path from soil solution to a downstream pond in a recently constructed catchment (Chicken Creek Catchment, Germany). Soil solution, upwelling ground water, subsurface water in an alluvial fan, and pond water all had high DOC concentrations (averaged 6.0 - 11.6 mg DOC L-1), despite small carbon stocks in either vegetation or soil of the catchment. The mean 14C age of DOC in upwelling ground water was 2600 to 2800 years. Solid-state CPMAS 13C NMR revealed a higher proportion of aromatic compounds (32\%) and a lower proportion of carbohydrates (33\%) in upwelling ground water compared to pond water (18\% and 45\%, respectively). 14C age and 13C NMR spectra suggest that DOC was partly mobilized from charred organic matter inherent in the Quaternary substrate. In a 70-days incubation experiment, 20\% of the total DOC was found to be bioavailable, irrespective of the water type. Origin of the microbial communities within the catchment (enriched from soil, stream sediment or pond water) had only marginal effects on overall DOC utilization. Overall, our data suggest that both recent and old DOC support microbial activity during early ecosystem succession, although a large fraction of the DOC is recalcitrant and eventually exported from the catchment once it has been mobilized.}, language = {en} } @inproceedings{HinzGerwinSchaafetal., author = {Hinz, Christoph and Gerwin, Werner and Schaaf, Wolfgang and Elmer, Michael and Fl{\"u}hler, Hannes and Holl{\"a}nder, Hartmut M. and H{\"u}ttl, Reinhard F.}, title = {State transitions in the artificial catchment Huehnerwasser (Chicken Creek): Ecosystems development 8 years after initialization : abstract}, series = {Soil-mediated Drivers of Coupled Biogeochemical and Hydrological Processes across Scales, AGU Chapman Conference Biosphere II, Tucson, Arizona, USA, 21-24 October 2013}, booktitle = {Soil-mediated Drivers of Coupled Biogeochemical and Hydrological Processes across Scales, AGU Chapman Conference Biosphere II, Tucson, Arizona, USA, 21-24 October 2013}, pages = {S. 34}, language = {en} } @incollection{DillyNiiAnnangSchrautzeretal., author = {Dilly, Oliver and Nii-Annang, Seth and Schrautzer, J. and Schwartze, P. and Breuer, P. and Pfeiffer, Eva-Maria and Gerwin, Werner and Schaaf, Wolfgang and Freese, Dirk and Veste, Maik and H{\"u}ttl, Reinhard F.}, title = {Ecosystem Manipulation and Restoration on the Basis of Long-Term Conceptions}, series = {Long-Term Ecological Research Between Theory and Application}, booktitle = {Long-Term Ecological Research Between Theory and Application}, editor = {M{\"u}ller, Felix and Baessler, Cornelia and Schubert, Hendrik and Klotz, Stefan}, publisher = {Springer Netherlands}, address = {Dordrecht}, isbn = {978-90-481-8781-2}, pages = {411 -- 428}, language = {en} } @incollection{Schaaf, author = {Schaaf, Wolfgang}, title = {Soil solution}, series = {Initial development of the artificial catchment "Chicken Creek" : monitoring program and survey 2005-2008}, booktitle = {Initial development of the artificial catchment "Chicken Creek" : monitoring program and survey 2005-2008}, editor = {Schaaf, Wolfgang and Biemelt, Detlef and H{\"u}ttl, Reinhard F.}, publisher = {Univ. of Technology, Research Center Landscape Development and Mining Landscapes}, address = {Cottbus}, pages = {45 -- 56}, language = {en} } @inproceedings{SchaafGerwinBiemeltetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Biemelt, Detlef and Fischer, Anton}, title = {Monitoring of initial patterns and structures in an artificial catchment}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 -
