Chronic and Acute Effects of Imidacloprid on a Simulated BEEHAVE Honeybee Colony
(Environmental Toxicology and Chemistry, 2022-08-17)Honeybees (Apis mellifera) are important pollinators for wild plants as well as for crops, but honeybee performance is threatened by several stressors including varroa mites, gaps in foraging supply, and pesticides. The ... -
Greigite (Fe3S4) Formation in Artificial Sediments via Solid‐State Transformation of Lepidocrocite
; ; (Geochemistry, Geophysics, Geosystems, 2022-08-12)
Greigite (Fe3S4) is a ferrimagnetic iron‐sulfide mineral that forms in sediments during diagenesis. Greigite growth can occur diachronously within a stratigraphic profile, complicating or overprinting environmental and ... -

New impact diagnostics for cross‐validation of different observation types
(Quarterly Journal of the Royal Meteorological Society, 2022-07-31)
New cross‐validation diagnostics have been derived by further partitioning well‐established impact diagnostics. They are related to consistency relations, the most prominent of which indicates whether the first‐guess ... -
Clockwise hysteresis of diatoms in response to nutrient dynamics during eutrophication and recovery
(Limnology and Oceanography, 2022-07-28)Many lake ecosystems that have been severely disturbed by eutrophication, have also experienced large human efforts to restore “natural” conditions. However, the trajectories and the extent of recovery of these lake ... -
Capturing complex star dune dynamics—repeated highly accurate surveys combining multitemporal 3D topographic measurements and local wind data
; ; ; (Earth Surface Processes and Landforms, 2022-07-25)
Morphologies of highly complex star dunes are the result of aeolian dynamics in past and present times. These dynamics reflect climatic conditions and associated forces like sediment availability and vegetation cover, as ... -
MAGEMin, an Efficient Gibbs Energy Minimizer: Application to Igneous Systems
; ; ; (Geochemistry, Geophysics, Geosystems, 2022-07-18)
Prediction of stable mineral equilibria in the Earth's lithosphere is critical to unravel the tectonomagmatic history of exposed geological sections. While the recent advances in geodynamic modeling allow us to explore the ... -
Spatio‐Temporal Level Variations of the Martian Seasonal South Polar Cap From Co‐Registration of MOLA Profiles
; ; ; ; ; ; (Journal of Geophysical Research: Planets, 2022-07-18)
The seasonal deposition and sublimation of CO2 represents a major element in the Martian volatile cycle. Here, co‐registration strategies are applied to Mars Orbiter Laser Altimeter profiles to obtain spatio‐temporal ... -
The first belemnite of boreal ancestry from the Early Cretaceous (Valanginian) of the western Tethys: implications for belemnite ecology
; ; (Papers in Palaeontology, 2022-07-17)
The first occurrence of the belemnite species Liobelus acrei (formerly Acroteuthis acrei) is reported from the Lower Cretaceous (Valanginian) of the Vocontian Basin (VB; south‐east France). This first record of the genus ... -
Analytical Artefacts Preclude Reliable Isotope Ratio Measurement of Internal Water in Coral Skeletons
; ; ; ; ; ; ; ; ; (Geostandards and Geoanalytical Research, 2022-07-12)
Internal water in cold‐water and tropical coral skeletons was extracted and measured for its oxygen and hydrogen isotope ratios. Water was extracted by crushing pieces of coral hard tissue in a percussion device connected ... -
Algorithmic Differentiation for Sensitivity Analysis in Cloud Microphysics
; ; ; (Journal of Advances in Modeling Earth Systems, 2022-07-12)
The role of clouds for radiative transfer, precipitation formation, and their interaction with atmospheric dynamics depends strongly on cloud microphysics. The parameterization of cloud microphysical processes in weather ... -
Geomagnetic Detection of the Atmospheric Acoustic Resonance at 3.8 mHz During the Hunga Tonga Eruption Event on 15 January 2022

Modeling studies have predicted that the acoustic resonance of the atmosphere during geophysical events such as earthquakes and volcanos can lead to an oscillation of the geomagnetic field with a frequency of about 4 mHz. ... -
Millimetre scale aeration of the rhizosphere and drilosphere
; ; (European Journal of Soil Science, 2022-07-06)
Soil aeration is a critical factor for oxygen‐limited subsoil processes, as transport by diffusion and advection is restricted by the long distance to the free atmosphere. Oxygen transport into the soil matrix is highly ... -
