Pollen record from samples with at least 15 pollen grains from Merscheider Maar core MS1

Pollen record of a sediment core from the Neualbenreuth Maar, Germany

The Neualbenreuth Maar (49°58' N, 12°28' E, 601 m asl) is a filled up former maar lake, located within a presently swampy depression 2.5 km ESE of the village Neualbenreuth (NE-Bavaria, Germany). It represents one of four hitherto known volcanic structures of Pleistocene age along the NNW-SSE trending Tachov fault zone. The maar structure was detected by gravity surveys and was subsequently confirmed by the recovery of lake sediments by an exploratory drilling campaign in 2015. Within the scope of a pilot study, a set of 141 pollen samples collected from sediment depths between 17.7 to 96.0 m below the recent surface. The samples were analyzed in order to evaluate the potential of the sequence for detailed palaeoenvironmental investigations, and to estimate the age of the sedimentary record. The pollen analyses from the Neualbenreuth Maar sediments reveal a continuous record of vegetation and climate changes encompassing four interglacial stages and five cold periods. The dominance of cold and dry tolerant herbs and the sparse representation trees and shrubs during most parts of the sequence indicates open landscapes of steppe to woody-steppe character typically of late Middle and Late Pleistocene glacial periods in Central Europe. The pollen assemblages of the warm stage in the upper part of the core clearly support its correlation with the Eemian interglacial (MIS 5e). The three pre-Eemian warm stages represent terrestrial analogues of the marine isotope stages (MIS) 7e, 7c, and 7a within the Saalian glacial period. In Central Europe, which was strongly affected by glacial and periglacial processes during the major Middle and Late Pleistocene cold periods, palaeoecological evidence of the Saalian complex of alternating warm and cold stages is ambiguous so far. The Neualbenreuth record provides the first biostratigraphical sequence from this region covering MIS 8 to 5 without notable depositional gaps

Plant wax composition of sediment core ROT21 from the Rotsee, Switzerland

This dataset contains compound-specific hydrogen (δ2H) and carbon (δ13C) isotope compositions and concentrations of long-chain n-alkanes and fatty acids (n-alkanoic acids) from the ROT21 sediment record of Rotsee, Central Switzerland (47°04′10″N, 8°18′48″E, 419 m a.s.l.). Sediment cores were retrieved in October 2021 using a UWITEC gravity corer, and the dataset spans the past ~13,000 years based on 19 radiocarbon dates (terrestrial and aquatic macrofossils) integrated with 210Pb and 137Cs profiles (see De Jonge et al., 2025). Laboratory analyses were conducted between February 2023 and November 2024 at the University of Basel. Sediment samples (~2–5 g) were sub-sampled, freeze-dried, spiked with internal standards (n-C19-alkanoic acid, n-C36-alkane, 2-octadecanone, and n-C21-alkanol), and extracted with dichloromethane/methanol (9:1, v/v) using an Accelerated Solvent Extractor (Dionex ASE 350, Thermo Fisher Scientific). Following saponification, neutral fractions were separated via silica gel chromatography, and fatty acids were converted to fatty acid methyl esters (FAMEs). Both n-alkanes and FAMEs were further purified to isolate saturated compounds using AgNO3-impregnated silica gel columns, then analyzed and quantified by gas chromatography with flame ionization detection (GC-FID). Peak areas were normalized to recovery standards to account for potential losses during sample handling, and compounds were identified by comparison with external standards. Compound-specific δ2H and δ13C values were determined by gas chromatography-isotope ratio mass spectrometry (GC-IRMS) and normalized to the VSMOW-SLAP (δ2H) and VPDB (δ13C) scales. Analytical precision was ±3-5 ‰ for δ2H and ±0.2–0.3 ‰ for δ13C. The dataset was generated to reconstruct past hydroclimate and vegetation dynamics in Central Europe using plant wax δ2H records. Full methodological details are provided in the study: Central Europe hydroclimate since the Younger Dryas inferred from vegetation-corrected sedimentary plant wax δ2H values (Santos et al., 2026).

Spatial distribution of fine-grained floodplain deposits and anthropogenic materials based on official borehole data in the floodplain of Leipzig, Germany

This data set contains data representing the thickness and spatial distribution of fine-grained floodplain deposits and anthropogenic material in the Leipzig floodplain area. It includes four raster layers (.tif format): one showing the interpolated distribution of the top level of fluvial gravel deposits in the floodplain and one showing the top level of fluvial gravels. The third raster layer presents the thickness of fine-grained floodplain deposits. Additionally, the stratigraphic data was used to spatially model the distribution of thickness of the anthropogenic material in the research area. A shapefile is provided, containing processed data from 3,414 drillings used to develop the spatial model. The data set originates from drilling records provided by the Saxon State Office for Environment, Agriculture, and Geology (LfULG) which were filtered and categorized by their stratigraphical characteristics. Further information on methodological details is described in Graubner and Schmidt (2024) - Data in Brief.

Unterschiedliche emotionale Wahrnehmung von Totholz durch deutsche und tschechische Besucherinnen und Besucher in den Nationalparken Bayerischer Wald und Šumava

Der Nationalpark (NLP) Bayerischer Wald und der tschechische NLP Šumava, die gemeinsam das größte zusammenhängende streng geschützte Waldgebiet Mitteleuropas bilden, sind seit Anfang der 1990er-Jahre von Massenvermehrungen von Borkenkäfern betroffen. Die damit verbundenen Totholzflächen prägen das Waldbild und die Wahrnehmung der Besucherinnen und Besucher. Im Rahmen eines grenzüberschreitenden sozioökonomischen Monitorings wurde 2018/2019 in beiden NLP eine standardisierte Befragung zum Naturerlebnis und zur Wahrnehmung von Totholzflächen durchgeführt (N = 867). Ziel war es, mehr über die emotionale Totholzwahrnehmung der deutschen und tschechischen Besucherinnen und Besucher zu erfahren und Unterschiede bei den Zusammenhängen zwischen soziodemographischen Faktoren und der Totholzwahrnehmung zu untersuchen. Dabei konnten signifikante Unterschiede zwischen den Gästen der beiden NLP identifiziert werden. Im Gegensatz zu den deutschen Befragten empfanden die tschechischen Befragten häufiger Stress- und Trauergefühle, wenn sie große Flächen mit Totholz sahen. Es zeigte sich zudem, dass soziodemographische Faktoren und die emotionale Totholzwahrnehmung bei deutschen und tschechischen Befragten unterschiedlich zusammenhingen. Während bei den tschechischen Befragten Frauen und ältere Personen Totholz tendenziell stärker mit negativen Gefühlen verbanden, waren dies bei den deutschen Befragten Personen ohne Hochschulabschluss. Signifikante Unterschiede zwischen den beiden Gruppen konnten jedoch nur beim Faktor Alter identifiziert werden. Als Gründe für die unterschiedliche Totholzwahrnehmung können voneinander abweichende historische Entwicklungen und soziokulturelle Bedeutungszuschreibungen der beiden NLP angeführt werden. Die vorliegenden Erkenntnisse können als Orientierungsrahmen für eine dialogorientierte Öffentlichkeitsarbeit dienen, die zielgruppenspezifische Informationsangebote bereitstellt.

LAPRO2009 - Sicherung ( historisch ) alter Waldstandorte

Als alte Waldstandorte werden im Landschaftsprogramm Saarland Flächen bezeichnet, die über mehrere Jahrhunderte (soweit Kartenaufzeichnungen vorliegen) als Waldflächen Bestand hatten. In diesen Bereichen ist davon auszugehen, dass sich die Bodenentwicklung unter dem Waldschirm (natürlich unter Einfluss der unterschiedlichen Waldnutzungsphasen mit Rottwald, Nieder- und Mittelwald sowie Alterklassenwald mit Nadelholzanbau) noch in der für Mitteleuropa naturnächsten Weise vollzogen hat. Eine naturnahe Bestockung muss nicht vorliegen. s. Landschaftsprogramm Saarland, Kapitel 9.6.1. (Stand Juni 2009)
