Temperate agroforestry potentially improves ecosystem functions, although comprehensive analysis is lacking. Here, we measured primary data on 47 indicators of seven ecosystem functions in croplands and 16 indicators of four ecosystem functions in grasslands to assess how alley-cropping agroforestry performs compared to open cropland and grassland. Carbon sequestration, habitat for soil biological activity, and wind erosion resistance improved for cropland agroforestry (P ≤ 0.03) whereas only carbon sequestration improved for grassland agroforestry (P \< 0.01). In cropland agroforestry, soil nutrient cycling, soil greenhouse gas abatement, and water regulation did not improve, due to customary high fertilization rates. Alley-cropping agroforestry increased multifunctionality, compared to open croplands. To ameliorate the environmental benefits of agroforestry, more efficient use of nutrients is required. Financial incentives should focus on conversion of open croplands to alley-cropping agroforestry and incorporate fertilizer management.}, language = {en} } @misc{UllrichNueskeScheibneretal., author = {Ullrich, Ren{\´e} and N{\"u}ske, J{\"o}rg and Scheibner, Katrin and Spantzel, J{\"o}rg and Hofrichter, Martin}, title = {Novel Haloperoxidase from the Agaric Basidiomycete Agrocybe aegerita Oxidizes Aryl Alcohols and Aldehydes}, series = {Applied and Environmental Microbiology}, volume = {70}, journal = {Applied and Environmental Microbiology}, number = {8}, issn = {1098-5336}, doi = {10.1128/AEM.70.8.4575-4581.2004}, pages = {4575 -- 4581}, abstract = {Agrocybe aegerita, a bark mulch- and wood-colonizing basidiomycete, was found to produce a peroxidase (AaP) that oxidizes aryl alcohols, such as veratryl and benzyl alcohols, into the corresponding aldehydes and then into benzoic acids. The enzyme also catalyzed the oxidation of typical peroxidase substrates, such as 2,6-dimethoxyphenol (DMP) or 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS). A. aegerita peroxidase production depended on the concentration of organic nitrogen in the medium, and highest enzyme levels were detected in the presence of soybean meal. Two fractions of the enzyme, AaP I and AaP II, which had identical molecular masses (46 kDa) and isoelectric points of 4.6 to 5.4 and 4.9 to 5.6, respectively (corresponding to six different isoforms), were identified after several steps of purification, including anion- and cation-exchange chromatography. The optimum pH for the oxidation of aryl alcohols was found to be around 7, and the enzyme required relatively high concentrations of H2O2 (2 mM) for optimum activity. The apparent Km values for ABTS, DMP, benzyl alcohol, veratryl alcohol, and H2O2 were 37, 298, 1,001, 2,367 and 1,313 μM, respectively. The N-terminal amino acid sequences of the main AaP II spots blotted after two-dimensional gel electrophoresis were almost identical and exhibited almost no homology to the sequences of other peroxidases from basidiomycetes, but they shared the first three amino acids, as well as two additional amino acids, with the heme chloroperoxidase (CPO) from the ascomycete Caldariomyces fumago. This finding is consistent with the fact that AaP halogenates monochlorodimedone, the specific substrate of CPO. The existence of haloperoxidases in basidiomycetous fungi may be of general significance for the natural formation of chlorinated organic compounds in forest soils.}, language = {en} } @misc{HiemannHilgerMicheletal., author = {Hiemann, Rico and Hilger, Nadja and Michel, J{\"o}rg and Nitschke, J{\"o}rg and B{\"o}hm, Alexander and Anderer, Ursula and Weigert, Martin and Sack, Ulrich}, title = {Automatic Analysis of Immunofluorescence Patterns of HEp-2 Cells}, series = {Annals of the New York Academy of Sciences}, volume = {1109}, journal = {Annals of the New York Academy of Sciences}, number = {1}, issn = {0077-8923}, doi = {10.1196/annals.1398.042}, pages = {358 -- 371}, abstract = {The standard screening test for the recognition of autoimmune diseases is the proof of autoantibodies in serum of patients by indirect immunofluorescence (IIF) based on HEp-2 cells.

Interlaboratory tests showed occasionally large deviations in the test evaluation resulting in a high variance of results. The aim of this project is fast, objective, safe, and economical automatic analysis of HEp-2 IIF patterns. Images of IIF patterns were completely and automatically captured using an inverse motorized fluorescence microscope. Thereby, device-specific parameters were controlled automatically, too. For fast analysis of IIF patterns new algorithms of image processing were developed. Artifacts were recognized and excluded from analysis by the developed software. Analysis of more than 80,000 images clearly demonstrated full automatization and fast processing of IIF patterns. Additionally serum-specific fluorescence could be easily distinguished from background. Even very weak but positive patterns can be recognized and used for diagnosis. A detailed separation into different basic patterns is possible. Objective, fast, and disease-related economical analysis of HEp-2 immunofluorescence patterns is feasible. The implemented software algorithms allowed a mathematical way of describing IIF patterns and can therefore be a useful tool for the needed standardization process.}, language = {en} } @inproceedings{WarneckeHoehneMartinetal., author = {Warnecke, Martin and H{\"o}hne, Olaf and Martin, J{\"o}rg S. and Krautz, Hans Joachim}, title = {Monte-Carlo-Simulationen zur Ermittlung der Zeitverf{\"u}gbarkeit der Braunkohletrocknung f{\"u}r ein Tbk-Kraftwerkskonzept}, language = {de} } @misc{OehmeKosteckiArguirovetal., author = {Oehme, Michael and Kostecki, Konrad and Arguirov, Tzanimir V. and Mussler, Gregor and Ye, Kaiheng and Gollhofer, Martin and Schmid, Marc and Kaschel, Mathias and K{\"o}rner, Roman and Kittler, Martin and Buca, Dan and Kasper, Erich and Schulze, J{\"o}rg}, title = {GeSn Heterojunction LEDs on Si Substrates}, series = {IEEE Photonics Technology Letters}, volume = {26}, journal = {IEEE Photonics Technology Letters}, number = {2}, issn = {1041-1135}, doi = {10.1109/LPT.2013.2291571}, pages = {187 -- 189}, language = {en} } @misc{OehmeWidmannKosteckietal., author = {Oehme, Michael and Widmann, Daniel and Kostecki, Konrad and Zaumseil, Peter and Schwartz, Bernhard and Gollhofer, Martin and K{\"o}rner, Roman and Bechler, Stefan and Kittler, Martin and Kasper, Erich and Schulze, J{\"o}rg}, title = {GeSn/Ge Multi Quantum Well Photodetectors on Si Substrates}, series = {Optics Letters}, volume = {39}, journal = {Optics Letters}, number = {16}, issn = {1539-4794}, doi = {10.1364/OL.39.004711}, pages = {4711 -- 4714}, language = {en} } @misc{SchwartzOehmeKosteckietal., author = {Schwartz, Bernhard and Oehme, Michael and Kostecki, Konrad and Widmann, Daniel and Gollhofer, Martin and K{\"o}rner, Roman and Bechler, Stefan and Fischer, Inga Anita and Wendav, Torsten and Kasper, Erich and Schulze, J{\"o}rg and Kittler, Martin}, title = {Electroluminescence of GeSn/Ge MQW LEDs on Si substrate}, series = {Optics Letters}, volume = {40}, journal = {Optics Letters}, number = {13}, doi = {10.1364/OL40.003209}, pages = {3209 -- 3212}, language = {en} } @misc{OehmeGollhoferKosteckietal., author = {Oehme, Michael and Gollhofer, Martin and Kostecki, Konrad and K{\"o}rner, Roman and Bechler, Stefan and Widmann, Daniel and Aguirov, Tzanimir and Kittler, Martin and Schulze, J{\"o}rg}, title = {Ge and GeSn Light Emitters on Si}, series = {Solid State Phenomena}, volume = {242}, journal = {Solid State Phenomena}, issn = {1012-0394}, doi = {10.4028/www.scientific.net/SSP.242.353}, pages = {353 -- 360}, language = {en} } @inproceedings{LoefflerMartin, author = {L{\"o}ffler, Steffen and Martin, J{\"o}rg S.}, title = {Untersuchungen zu Einflussgr{\"o}ßen auf die W{\"a}rme{\"u}bertragung bei der druckaufgeladenen Dampfwirbelschichttrocknung von Braunkohle}, language = {de} } @misc{FechtWunderlichMeieretal., author = {Fecht, Hans-J{\"o}rg and Wunderlich, Rainer and Meier, Martin and Sprenger, Heinz}, title = {Measurement of Thermophysical Properties of Metallic Melts for High Quality Castings}, language = {en} } @inproceedings{MartinLoefflerKrautz, author = {Martin, J{\"o}rg S. and L{\"o}ffler, Steffen and Krautz, Hans Joachim}, title = {Druckaufgeladene Dampfwirbelschichttrocknung grubenfeuchter Braunkohle -

The present study assesses the implementation and parameterization of a state-of-art Land-Surface Model (LSM) for simulation of these fluxes over two representative p{\´a}ramo catchments of southern Ecuador. We evaluated the outputs of the LSM Community Land Model (CLM ver. 4.0) with (i) ground-level flux observations from the first (and highest) Eddy Covariance (EC) tower of the Northern Andean p{\´a}ramos; (ii) spatial ETa estimates from the energy balance-based model METRIC (based on Landsat imagery); and (iii) derived ETa from the closure of the water balance (WB). CLM's energy predictions revealed a significant underestimation on net radiation, which impacts the sensible and soil heat fluxes (underestimation), and delivers a slight overestimation on latent heat flux. Modeled CLM ETa showed acceptable goodness-of-fit (Pearson R = 0.82) comparable to ETa from METRIC (R = 0.83). Contrarily, a poor performance of ETa WB was observed (R = 0.46). These findings provide solid evidence on the CLM's accuracy for the ETa modeling, and give insights in the selection of other ETa methods.

Due to the rather complicated pathway of water, starting from precipitation until its uptake by trees and the final incorporation of its components into tree-ring cellulose, a closer inspection of seasonal variations of tree water uptake is important. In this study, branch and needle samples of two pine species (Pinus pinaster and Pinus nigra subsp. laricio) and several water compartments (precipitation, creek, soil) were sampled over a two-year period and analyzed for the temporal variations of their oxygen and hydrogen stable isotope ratios (δ18O and δ2H) at five sites over an elevation gradient from sea level to around 1600 m a.s.l. on the Mediterranean island of Corsica (France). A new model was established to disentangle temporal relationships of source water uptake of trees. It uses a calculation method that incorporates the two processes mostly expected to affect source water composition: mixing of waters and evaporation. The model results showed that the temporal offset from precipitation to water uptake is not constant and varies with elevation and season. Overall, seasonal source water origin was shown to be dominated by precipitation from autumn and spring. While autumn precipitation was a more important water source for trees growing at mid- (~800-1000 m a.s.l) and high-elevation (~1600 m a.s.l.) sites, trees at coastal sites mostly took up water from late winter and spring.

We traced back the oxygen isotope composition from source to sink in tree-ring cellulose in order to identify the water sources used by the trees, and to quantify the extent of isotope fractionation processes. Our results showed that the trees used different water sources over the course of the growing season, ranging from winter snow meltwater to summer precipitation at higher sites and deep soil water reservoirs at coastal sites. Needle water enrichment was higher at higher elevation sites than at coastal locations, highlighting the importance of site-specific climate conditions on the isotopic composition values in tree material. Water availability seems to be most restricted at the highest site, making these trees most vulnerable to climate change.}, language = {en} } @misc{SzymczakHaeusserGareletal., author = {Szymczak, Sonja and H{\"a}usser, Martin and Garel, Emilie and Santoni, S{\´e}bastien and Huneau, Fr{\´e}d{\´e}ric and Knerr, Isabel and Trachte, Katja and Bendix, J{\"o}rg}, title = {How Do Mediterranean Pine Trees Respond to Drought and Precipitation Events along an Elevation Gradient}, series = {Forests}, volume = {7}, journal = {Forests}, number = {11}, doi = {10.3390/f11070758}, pages = {17}, abstract = {Drought is a major factor limiting tree growth and plant vitality. In the Mediterranean region,the length and intensity of drought stress strongly varies with altitude and site conditions. We usedelectronic dendrometers to analyze the response of two native pine species to drought and precipitationevents. The five study sites were located along an elevation gradient on the Mediterranean islandof Corsica (France). Positive stem increment in the raw dendrometer measurements was separatedinto radial stem growth and stem swelling/shrinkage in order to determine which part of the trees'response to climate signals can be attributed to growth. Precipitation events of at least 5 mm anddry periods of at least seven consecutive days without precipitation were determined over a periodof two years. Seasonal dynamics of stem circumference changes were highly variable among thefive study sites. At higher elevations, seasonal tree growth showed patterns characteristic for coldenvironments, while low-elevation sites showed bimodal growth patterns characteristic of droughtprone areas. The response to precipitation events was uniform and occurred within the first six hoursafter the beginning of a precipitation event. The majority of stem circumference increases were causedby radial growth, not by stem swelling due to water uptake. Growth-induced stem circumferenceincrease occurred at three of the five sites even during dry periods, which could be attributed tostored water reserves within the trees or the soils.

A potential, but not very widespread source of water is the presence of near-ground clouds, mostly fog. In this study, we investigate fog-low stratus (FLS) frequencies in Corsica, derived from a data set of Meteosat Second Generation SEVIRI, whereby a distinction between fog and low stratus is hardly feasible using remote sensing data. The FLS frequency was studied with respect to its interaction with distinct locally-generated wind and its dependence on the planetary boundary layer height (PBLH) obtained by ERA5 reanalysis (the fifth generation of the European Centre for Medium-Range Weather Forecasts, ECMWF). Results show that radiation FLS is formed in coastal areas at sunrise, with low PBLH. On the other hand, in the interior of the island at sunset, a maximum of advection FLS is formed, fostered by locally-generated and related transport of moisture. On the east side of the island, FLS frequency is lower throughout the year due to frequent lee situations. This situation is reinforced by reduced synoptic moisture transport by westerly winds, so that westerly exposed slopes benefit from moisture input by FLS formation.}, language = {en} } @misc{EbnervonEschenbachHelmsKleinhansetal., author = {Ebner von Eschenbach, Anna and Helms, Martin and Kleinhans, Alexander and Laaha, Gregor and Sch{\"u}mberg, Sabine and Walther, J{\"o}rg and Willems, Winfried}, title = {DWA-AG HW-3.1: „Niedrigwasser" - unser Weg zum neuen Merkblatt DWA-M 541 „Statistische Analyse von Niedrigwasserkenngr{\"o}ßen"}, series = {KW Korrespondenz Wasserwirtschaft}, volume = {14}, journal = {KW Korrespondenz Wasserwirtschaft}, number = {10}, issn = {1865-9926}, pages = {625 -- 630}, abstract = {Nach mehrj{\"a}hriger Arbeit der DWA-Arbeitsgruppe HW-3.1 „Niedrigwasser" hat die DWA im Oktober 2020 den Gelbdruck f{\"u}r das Merkblatt DWA-M 541 „Statistische Analyse von Niedrigwasserkenngr{\"o}ßen" ver{\"o}ffentlicht.

However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a 'slow-fast' axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning.

SPARE-AD, an MRI index capturing AD-like atrophy, and atrophy-based estimates of brain age were computed from longitudinal structural imaging data of 178 PD patients and 84 healthy subjects from the LANDSCAPE cohort. All patients underwent an extensive neuropsychological test battery. Patients diagnosed with mild cognitive impairment or dementia were found to have higher SPARE-AD scores as compared to patients with normal cognition and healthy controls. All patient groups showed increased brain age. SPARE-AD predicted impairment in memory, language and executive functions, whereas advanced brain age was associated with deficits in attention and working memory.

The present study quantifies the variability of xylogenesis along an elevation gradient on the Mediterranean island of Corsica, where two native pine species (Pinus nigra Arnold ssp. laricio Maire and Pinus pinaster Aiton) grow from the upper tree line to sea level, partly in sympatry. We extracted microcores from 35 trees at 5 sites along an East-West transect from the coasts (10 m asl) to the island's central mountain ridge (1600 m asl) during bi-weekly sampling campaigns between 2017 and 2019. We applied generalised additive models to detect radial growth differences in elevation and species along with minimum temperatures for growth initiation. We found that trees in low elevations experienced over 2 months longer growth periods with higher maximum growth rates than in high elevations. The results show a 1-month delay for the beginning of tracheid formation between the low, mid and high-elevation belts but comparable timing for its termination. At the sites where both species co-occur, P. nigra accumulates more radial cells in a shorter time than P. pinaster. Trees at the two contrasting coastal sites have similar growth period lengths, but exhibit a time shift of over a month. Minimum temperatures around growth initiation vary between 3.1 °C for P. nigra and 9.9 °C for P. pinaster.
