An ancient process in a modern mollusc: early development of the shell in Lymnaea stagnalis
(BMC Developmental Biology, 2013)Background The morphological variety displayed by the molluscan shell underlies much of the evolutionary success of this phylum. However, the broad diversity of shell forms, sizes, ornamentations and functions contrasts ... -
An andesitic sill complex in the Southern Permian Basin: volcanogenetic model and stratigraphic implications
; ; ; ; ; ; ; ; (International Journal of Earth Sciences, 2020-07-28)
Subvolcanic intrusions are highly variable in shape and structure, and occur in nearly all parts of the upper crust, as a result of extensive volcanic activity. Processes of subvolcanics interacting with the host rock are ... -
An Antarctic molluscan biomineralisation tool-kit
(Scientific Reports, 2016)The Antarctic clam Laternula elliptica lives almost permanently below 0 °C and therefore is a valuable and tractable model to study the mechanisms of biomineralisation in cold water. The present study employed a ... -
An application of WKBJ theory for triad interactions of internal gravity waves in varying background flows
; Akylas, T. R.; (Quarterly Journal of the Royal Meteorological Society, 2021-01-22)
Motivated by the question of whether and how wave–wave interactions should be implemented into atmospheric gravity‐wave parametrizations, the modulation of triadic gravity‐wave interactions by a slowly varying and vertically ... -
An Asthenospheric Upwelling Beneath Central Mongolia — Implications for Intraplate Surface Uplift and Volcanism
; ; ; ; ; ; ; (Acta Geologica Sinica ‐ English Edition, 2021-11-27)
Intraplate processes, such as continental surface uplift and intraplate volcanism, are enigmatic and the underlying mechanisms responsible are not fully understood. Central Mongolia is an ideal natural laboratory for ... -
An automated testing device for continuous measurement of the hysteretic water retention curve of granular media
(Acta Geotechnica, 2020-02-11)
The water retention curve (WRC), representing an important key for the modelling of hydro-mechanical behaviour of unsaturated soils, is still not fully understood, because it originates from microscopic hydraulic and ... -
An early Eocene fossil from the British London Clay elucidates the evolutionary history of the enigmatic Archaeotrogonidae (Aves, Strisores)
(Papers in Palaeontology, 2021-07-18)
Archaeotrogons have long been known from late Eocene and Oligocene localities in France, where limb bones are abundantly represented. The phylogenetic affinities of these birds, however, have remained elusive. Although ... -
An earthquake catalogue for central, northern and northwestern Europe based on MW magnitudes
(Scientific Technical Report / Geoforschungszentrum Potsdam; 2003, 02) -
An Empirical Model of the Equatorial Electron Pitch Angle Distributions in Earth's Outer Radiation Belt
; ; ; ; ; ; ; (Space Weather, 2022-09-20)
In this study, we present an empirical model of the equatorial electron pitch angle distributions (PADs) in the outer radiation belt based on the full data set collected by the Magnetic Electron Ion Spectrometer (MagEIS) ... -
An endless summer: 2018 heat episodes in Europe in the context of secular temperature variability and change
; ; (International Journal of Climatology, 2020)
The year 2018 was affected by very long-lasting, stable summer conditions in vast parts of Europe, in many regions already starting in April and lasting until October. We investigate the thermal characteristics of this ... -
An Energy Conserving Vlasov Solver That Tolerates Coarse Velocity Space Resolutions: Simulation of MMS Reconnection Events
; ; (Journal of Geophysical Research: Space Physics, 2022-02-11)
Vlasov solvers that operate on a phase‐space grid are highly accurate but also numerically demanding. Coarse velocity space resolutions, which are largely unproblematic in particle‐in‐cell (PIC) simulations, can lead to ... -
An evaluation of operational and research weather forecasts for southern West Africa using observations from the DACCIWA field campaign in June–July 2016
; ; ; ; ; ; ; ; (Quarterly Journal of the Royal Meteorological Society, 2020)
Reliable and accurate weather forecasts, particularly those of rainfall and its extremes, have the potential to improve living conditions in densely populated southern West Africa (SWA). The limited availability of ... -
An exceptional sedimentary record of initial rifting on the East African Plateau in the Miocene: Lessons from depositional cyclicity and palaeoenvironmental proxies
; ; ; (The Depositional Record, 2022-11-20)
Knowledge about the initial tectonic and depositional dynamics, as well as the influence of early rifting on climate and environmental evolution remains speculative to a large extent, because sediments are usually deeply ... -
An Exhumation Pulse From the Nascent Franciscan Subduction Zone (California, USA)
; ; ; (Tectonics, 2020)
We investigated a suite of metabasite blocks from serpentinite matrix and shale matrix mélanges of the California Coast Ranges. Our new data set consists of 40Ar/39Ar dates of amphibole and phengite and U-Pb dates of ... -
An Extension Strain Type Mohr–Coulomb Criterion
(Rock Mechanics and Rock Engineering, 2021-08-20)
Extension fractures are typical for the deformation under low or no confining pressure. They can be explained by a phenomenological extension strain failure criterion. In the past, a simple empirical criterion for fracture ... -
An extremeness threshold determines the regional response of floods to changes in rainfall extremes
; ; ; ; ; ; (Communications Earth & Environment, 2021-08-26)
Precipitation extremes will increase in a warming climate, but the response of flood magnitudes to heavier precipitation events is less clear. Historically, there is little evidence for systematic increases in flood magnitude ... -
An Improved Model of the Earth’s Static Gravity Field Solely Derived from Reprocessed GOCE Data
; ; (Surveys in Geophysics, 2021-01-18)
After it was found that the gravity gradients observed by the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite could be significantly improved by an advanced calibration, a reprocessing project ... -
An innovative seismic risk assessment method and implications of strain rate-dependency on risk estimates
(2006)Eine probabilistische Methodologie zur Abschätzung des Erdbebenrisikos bei den bestehenden Gebäuden wurde präsentiert. Diese Methodologie erfasst Analysen der Erdbebengefährdung, der Bauwerksantwort, der Bauwerkschaden und ... -
An optimised whole mount in situ hybridisation protocol for the mollusc Lymnaea stagnalis
(BMC Developmental Biology, 2015)Abstract Background The ability to visualise the expression of individual genes in situ is an invaluable tool for developmental and evolutionary biologists; it allows for the characterisation of gene function, gene regulation ...
