Summary: This study presents Sr-isotope data on invertebrates from different zones in the Lower Cretaceous deposits in the Caucasus, contributing to a refined understanding of palaeoenvironmental events in the region. Integration of data from the Caucasus and Middle Volga regions reveals two local minima events in the Sr-isotope record for the Aptian-lower Albian interval. The decreases in Sr-87/Sr-86 during the early and late Aptian times were possibly initiated by sea-floor hydrothermal activity, leading to changes in temperature, oxygen levels, transgression, and bio-productivity.

Summary: The proposed taxonomies of the Solemyoidea are conflicted due to imperfect understanding of crucial ligament support structures and misconceptions about certain Paleozoic genera. Recent studies challenge the placement of Acharax and Solemya in separate taxa, suggesting they are monophyletic. The morphological analysis and DNA studies support a closer kinship between Acharax and Solemya.

Summary: A detailed study was conducted on calcareous nannofossil assemblages from twelve Upper Lower Barremian-Lower Aptian sections in the Subbetic Domain of the Betic Cordillera. This study describes new nannofossil species, emends one species, and clarifies the taxonomic concept of a marker species. The stratigraphic ranges of the new species were determined and correlated to standard ammonite biostratigraphy, and age estimates were calculated using astrochronologically tuned cyclostratigraphic data. Five new calcareous nannofossil subzones were proposed, enhancing the biostratigraphic resolution of the Upper Barremian at a regional scale. The study also discusses the morpho-evolutionary trends of selected nannofossil groups in relation to paleogeographic changes.

Summary: The establishment of a standard ammonite zonation for the Aptian and Albian stages in the Mediterranean region has faced difficulties due to paleobiogeographic reasons, taxonomic debates, and the presence of hiatus, condensation, and reworked levels. Additionally, the poor record of ammonites can be attributed to biotic crises and periodic oxygen depletion. This paper discusses the zonation for the Aptian and Albian stages, proposing changes and supporting the retention of certain zones. It also highlights the impossibility of adopting a zonation for the middle Albian based on hoplitid ammonites.

Summary: The study highlights the importance of understanding soil biogeochemical responses to increasing drought in the coming decades. It shows that both seasonal and experimental drought conditions can lead to changes in soil enzyme activities and resource availability, with a higher relative demand for phosphorus than carbon and nitrogen observed in soil microbial communities. The results suggest that prolonged drought may decrease soil organic matter decomposition and nutrient release, which could negatively impact plant and microbial nutrition.

Summary: In this study, we investigated the offspring production and growth patterns of the Asian mussel Sinanodonta woodiana in the thermal plume of the Odra River in Central Europe. We found that compared to males, females had more convex shells and tended to continue growth post-maturation, with offspring production and size linked to seasonality and gonadal activity. The study also revealed that females with higher levels of nutritive substances in their ovaries produced more and larger offspring, with distinct sizes of offspring observed in different seasons.

Summary: Reefal limestones of the Stramberk Carbonate Platform, preserved in deep-water flysch of the Outer Carpathians, contain rich coral assemblages of the Jurassic/Cretaceous transition. Symbiotic associations between corals and tube-dwelling macroorganisms were observed in Calamophylliopsis flabellum and Calamophylliopsis sp. Two types of tubes were recognized, likely produced by serpulids or organic-walled sabellid polychaete worms. This association represents possibly the oldest record of a sabellid-coral association, with indications of mutualistic or commensal symbiosis.

Summary: In Europe, the fossil record of sauropods in the uppermost Cretaceous is mainly found in Spain, France, and Romania. Recently, a significant discovery of titanosaurs' teeth was made in Els Nerets, Spain, which contains the largest tooth sample from the Late Cretaceous in Europe. The teeth show distinct characteristics but cannot be attributed to any known European species. Based on tooth morphology and wear facets distribution, a new taxon is proposed.

Summary: Conifer fossil woods from the Campanian Puntudo Chico Formation were studied, confirming the presence of Brachyoxylon currumillii and the introduction of Cupressinoxylon sp. cf. C. artabeae in the formation. The new specimens of Podocarpoxylon mazzonii suggest that this taxon is common in the Cretaceous to Eocene floristic assemblages. The growth-ring analysis of these fossil trees indicates their development under temperate and humid conditions, with slight sensitivity from year to year and a terminal event representing a cessation or retardation of cambial activity. Other paleoclimatic proxies suggest a temperate-warm and humid depositional environment with some semi-arid events in the Puntudo Chico Formation.
