Hydropower regulation reshapes littoral invertebrate communities: functional traits reveal impacts beyond richness and abundance

Abstract Freshwater lake ecosystems are increasingly affected by altered water level fluctuations (WLF) from hydropower regulation, yet impacts on lake biodiversity remain understudied. We investigated how regulation influences Ephemeroptera, Plecoptera and Trichoptera (EPT) comm...

Walrus population-specific marine reservoir offsets (ΔR) for calibration of radiocarbon dates: Implications for Arctic chronologies and medieval trade

Walruses have long played a vital role in Arctic subsistence and commercial economies, yet accurate radiocarbon dating of walrus-derived archaeological materials is complicated by regional variation in marine reservoir effects. This study presents new ΔR values derived from 31 ne...
