Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Soil Organic Carbon Stocks and Saturation Deficit in Mediterranean Olive Groves: Effects of Intensification and Management Practices

European Journal of Soil Science, Volume 77, Issue 5, September–October 2026.
Mediterranean olive grove soils operate at only 41% of their textural SOC saturation capacity, with a mean deficit of 64 Mg C ha−1. The deficit widens along the intensification gradient—rather than along the organic‐versus‐conventional dichotomy—pointing to a substantial unrealized potential for soil carbon sequestration through soil‐conservation ...

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 677-700, September 2026.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Fossils as cultural heritage: Scientific, commercial and legislative issues

Geology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.
Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 585-610, September 2026.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...
