Environmental reconstructions based on aquatic and terrestrial snails originating from the Early Bronze Age and the Late Islamic Period– A stable isotope case study from the Al-Khashbah archaeological Site, Sultanate of Oman Open
Fossil shells of terrestrial and aquatic snails provide important information for the reconstruction of the Early Bronze Age environmental conditions in the Sultanate of Oman. Terrestrial species can be used to reconstruct available and th…

Ba/Ca profiles in shells of Pecten maximus – A proxy for specific primary producers rather than bulk phytoplankton Open
Molar barium-to‑calcium ratios in bivalve shells (Ba/Cashell) have been proposed in a variety of studies to serve as a potential proxy for the reconstruction of phytoplankton dynamics. However, the link between phytoplankton and Ba/Cashell…

Microstructural Mapping of Arctica islandica Shells Reveals Environmental and Physiological Controls on Biomineral Size Open
The shells of long-lived bivalves record environmental variability in their geochemical signatures and are thus used extensively in marine high-resolution paleoclimate studies. To possibly overcome the limitations of the commonly employed …

Temperature-induced microstructural changes in shells of laboratory-grown Arctica islandica (Bivalvia) Open
Bivalve shells are increasingly used as archives for high-resolution paleoclimate analyses. However, there is still an urgent need for quantitative temperature proxies that work without knowledge of the water chemistry–as is required for δ…

Paleoceanography of the Late Cretaceous northwestern Tethys Ocean: Seasonal upwelling or steady thermocline? Open
In this study we attempted to assess whether seasonal upwelling or a steady thermocline persisted at the western margin of the Tethys Ocean during the late Turonian-early Coniacian interval. For this scope, we employed novel and published …

Seawater carbonate chemistry and growth, physiological performance of the Manila clam Ruditapes philippinarum Open
Ocean acidification may interfere with the calcifying physiology of marine bivalves. Therefore, understanding their capacity for acclimation and adaption to low pH over multiple generations is crucial to make predictions about the fate of …

The bivalve <i>Glycymeris planicostalis</i> as a high-resolution paleoclimate archive for the Rupelian (Early Oligocene) of central Europe Open
Current global warming is likely to result in a unipolar glaciated world with unpredictable repercussions on atmospheric and oceanic circulation patterns. These changes are expected to affect seasonal extremes and the year-to-year variabil…

The beast burrowed, the fluid followed – Crustacean burrows as methane conduits Open
An extensive pockmark field with associated methane-seep carbonates has recently been reported from the late Albian (Lower Cretaceous) Ubidepea Mudstone of the Black Flysch Group in the Basque Country, northern Spain, but the exact pathway…
