ABSTRACT In icon painting, chalk whiting is key to creating a gesso ground, providing a smooth, absorbent surface for paint. Calcareous nannofossils, tiny marine skeletons found in chalk, are an ideal tool for analyzing the origin of an icon's chalk ground, often the only reliable information about where the icon came from.

Co‐applying half‐rate BMC layer: (i) Reduced nutrient inputs and (ii) produced similar yield. ABSTRACT Developing high‐efficiency fertilizers with less environmental footprint is essential for sustainable cropping systems. This study evaluated a biochar mineral complex (BMC) to reduce nutrient leaching and increase nutrient use efficiency (NUE), yield,

ABSTRACT Mountain ranges like the European Alps harbour large endemic biodiversity shaped by Pleistocene climatic oscillations. The flightless bush‐cricket Anonconotus italoaustriacus, endemic to the Southern Limestone Alps (SLA) and the eastern Central Alps (CA), provides an ideal model to study the evolutionary and refugial dynamics of endemic alpine

ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...
