Distinctive Climate Change Features in Latvia and Their Implications for Freshwater Ecosystems

Climate change is increasingly affecting freshwater ecosystems across Northern Europe, yet the responses of inland waters differ according to regional climatic and environmental conditions. Latvia, located within the boreo-nemoral transition zone, provides an important case for u...

Paramagnetic defects and luminescence in praseodymium-activated alkaline earth pyrophosphates

Establishing defect-property systematics in complex materials remains an elusive challenge, requiring complementary spectroscopic techniques and correlated investigations across chemically related host lattices. This study presents a systematic overview of defect-mediated charge...

Gazing into the voids: the morphology of shell temper reveals pottery-making practices and pottery exchange among hunter-fishers in north-east Europe

Stereomicroscopic examination of voids from dissolved bivalve shell in hunter-fisher-gatherer pottery from Latvia (4th mill. BC) reveals several distinct morphologies useful for characterisation of this tempering material, thus permitting new insights into pottery production and...
