Partly taken from the materials and methods of https://doi.org/10.1016/j.baae.2022.12.003: To compare the activity densities of ground-dwelling predators between treatments with and without RAPs, spiders were sampled using pitfall traps, which were set up after each round of aphid counting (one per plot, twice per year; Brown & Matthews, 2016). The traps (with a volume of 400 ml and a width of 90 mm) were filled with a mixture of water and ethylene glycol (1:1; 120 ml) and dug at ground level into the middle of each plot. The traps were covered with a plastic roof and a metal grid (15 × 15 mm grid size) to avoid overflowing during rain and accidental rodent catches (Császár et al., 2018). The traps were activated for 7 days. Subsequently, all arthropods were transferred into 70% ethanol. Spiders were identified to species according to Nentwig et al. (2019). Spider hunting strategy (active hunter or web-builder) was used as the feeding trait according to Cardoso et al. (2011).
Im tropischen Afrika kommen ca. 180 Arten Myomorpha (mausartige Nagetiere i.w.S.) vor, deren Oekologie bis vor ca. 30 Jahren nahezu unerforscht war. Im Rahmen mehrerer Forschungsvorhaben seit 1963 wurden und werden schwerpunktmaessig die Gebiete Zaire und Rwanda bearbeitet; ferner Uganda, Kenia, Tanzania, Nord- und Suedsudan, Aethiopien. Dabei werden die Biome Feuchtsavanne, montane Gebiete und tropischer Regenwald und die darin enthaltenen Biotope auf die charakteristischen Myomorpha-Arten und deren habitatmaessige Zusammensetzung untersucht. Spezielle Fragen gelten der Ernaehrung, der Fortpflanzung und der Populationsdynamik. Ausserdem werden die Beziehungen zum Menschen, besonders in landwirtschaftlicher und medizinisch-hygienischer Hinsicht untersucht.
Ausgehend von der Kenntnis der Struktur, Funktion und Regulation von Zellerneuerungssystemen unter besonderer Beruecksichtigung der Haematopoese ist es die Aufgabe dieses Projektes, die pathophysiologischen Mechanismen zu untersuchen und aufzuklaeren, die es dem menschlichen und tierischen Organismus erlauben, chronische niedrig dosierte Schadstoffexpostionen zu tolerieren. In Schadstoffexpositionskammern werden Nagetiere ueber kuerzere oder laengere Zeit mit Schadstoffen (z.B. organische Loesungsmittel) exponiert und es wird untersucht, wie verschiedene Zellerneuerungssysteme, insbesondere der Blutzellbildung durch eine Schadstoffexposition gestoert werden und welches die Indikatoren fuer eine fruehzeitige Erkennung von neoplastischen und nicht-neoplastischen Stoerungen sind. Beim Menschen, insbesondere bei Arbeitern aus schadstoffbelasteten Dienstleistungszweigen, wird ebenfalls der Versuch unternommen, Indikatoren fuer Belastung durch krebserzeugende und nicht-krebserzeugende Schadstoffe (z.B. Zytostatika, Schwermetalle) zu finden und diese aufzuklaeren.
Grainsize data supports palaeoclimatic reconstruction of glacial/interglacial cycles for the Middle Pleistocene sediment record from the crater basin of Rodderberg, Germany. A sediment record measuring 72.8 m in length was retrieved by employing wire-line drilling techniques, utilising 3 m-long liners, from the silted-up crater basin of Rodderberg (East Eifel Volcanic Field) in the vicinity of the city of Bonn, Germany. For the purpose of grainsize analysis, the composite record ROD11 was systematically subsampled at a spatial resolution of 2 cm and examined through a laser diffraction particle size analyser (Beckman Coulter LS 13320). The resulting sedimentological data characterise glacials as silt-dominated (aeolian sediments: loess), interglacials as sand-dominated (runoff-related deposits from the step crater walls) and clay dominance for the Holocene soil. The terrestrial sediment record has been evaluated through multiple dating techniques and it provides a comprehensive environmental reconstruction since the Middle Pleistocene, thus providing valuable insights into the region's climate history.
Cutting samples of 23 geological formations from different depths (measured depth, MD) between 1.4 and 4.4 km of the geothermal research well Groß Schönebeck site were analyzed with focus on lithium (Li), copper (Cu), and strontium (Sr). To determine how strong and to which components these critical raw materials (CRM) are bound within the rocks, leaching and sequential extraction experiments were performed on five selected formation rock samples that are considered either for geothermal exploitation (Muschelkalk, Buntsandstein, Rotliegend sandstone) and/or as potential source for the CRM Li, Cu, Sr from the Permo-Carboniferous volcanic rocks and/or the Ohre anhydrite. In addition, electron probe micro analyses (EPMA) and laser ablation ICP-OES was performed on thin sections of the Rotliegend formation.
This dataset contains experimental data from a one-month aquarium-based bleaching experiment conducted on Large Benthic Foraminifera (Amphistegina lobifera) from 16 November to 16 December 2022 at the Marine Experimental Facility of the Leibniz Centre for Tropical Marine Research (ZMT), Bremen, Germany. The aim of the experiment was to obtain symbiont-free A. lobifera individuals for future re-inoculation studies and symbiont switching experiments. The foraminifera were originally collected in May 2022 at the Interuniversity Institute for Marine Sciences (IUI) in Eilat, Israel (29°30'07.8N, 34°55'04.9E) and maintained in culture in Germany until the start of the experiment. To assess the effectiveness of two chemical agents—menthol and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU)—in disrupting symbiosis, photosynthetic efficiency (measured as maximum quantum yield, Fv/Fm) was recorded every other day during the first week of the experiment using a Pulse-Amplitude-Modulated (PAM) fluorometer. Fv/Fm measurements were discontinued after the first week due to complete inhibition of photosynthesis. Symbiont coverage (%) was assessed on day one and then weekly until week four using Confocal Laser Scanning Microscopy (CLSM).
This dataset contains geochemical variables measured in six depth profiles from ombrotrophic peatlands in North and Central Europe. Peat cores were taken during the spring and summer of 2022 from Amtsvenn (AV1), Germany; Drebbersches Moor (DM1), Germany; Fochteloër Veen (FV1), the Netherlands; Bagno Kusowo (KR1), Poland; Pichlmaier Moor (PI1), Austria and Pürgschachen Moor (PM1), Austria. The cores AV1, DM1 and KR1 were taken using a Wardenaar sampler (Royal Eijkelkamp, Giesbeek, the Netherlands) and had diameter of 10 cm. The cores FV1, PM1 and PI1 had an 8 cm diameter and were obtained using an Instorf sampler (Royal Eijkelkamp, Giesbeek, the Netherlands). The cores FV1, DM1 and KR1 were 100 cm, core AV1 was 95 cm, core PI1 was 85 cm and core PM1 was 200 cm. The cores were subsampeled in 1 cm (AV1, DM1, KR1, FV1) and 2 cm (PI1, PM1) sections. The subsamples were milled after freeze drying in a ballmill using tungen carbide accesoires. X-Ray Fluorescence (WD-XRF; ZSX Primus II, Rigaku, Tokyo, Japan) was used to determine Al (μg g-1), As (μg g-1), Ba (μg g-1), Br (μg g-1), Ca (g g-1), Cl (μg g-1), Cr (μg g-1), Cu (μg g-1), Fe (g g-1), K (g g-1), Mg (μg g-1), Mn (μg g-1), Na (μg g-1), P (μg g-1), Pb (μg g-1), Rb (μg g-1), S (μg g-1), Si (μg g-1), Sr (μg g-1), Ti (μg g-1) and Zn (μg g-1). These data were processed and calibrated using the iloekxrf package (Teickner & Knorr, 2024) in R. C, N and their stable isotopes were determined using an elemental analyser linked to an isotope ratio mass spectrometer (EA-3000, Eurovector, Pavia, Italy & Nu Horizon, Nu Instruments, Wrexham, UK). C and N were given in units g g-1 and stable isotopes were given as δ13C and δ15N for stable isotopes of C and N, respectively. Raw data C, N and stable isotope data were calibrated with certified standard and blank effects were corrected with the ilokeirms package (Teickner & Knorr, 2024). Using Fourier Transform Mid-Infrared Spectroscopy (FT-MIR) (Agilent Cary 670 FTIR spectromter, Agilent Technologies, Santa Clara, Ca, USA) humification indices (HI) were determined. Spectra were recorded from 600 cm-1 to 4000 cm-1 with a resolution of 2 cm-1 and baselines corrected with the ir package (Teickner, 2025) to estimate relative peack heights. The HI (no unit) for each sample was calculated by taking the ratio of intensities at 1630 cm-1 to the intensities at 1090 cm-1. Bulk densities (g cm-3) were estimated from FT-MIR data (Teickner et al., in preparation).
