Morphometric analysis of cirques in central Siberia's western Putorana Plateau: a proxy for palaeoclimate

Boreas, EarlyView.
A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...

Areas of high risk for mammalian biodiversity and nature's contributions to people under global warming

Conservation Science and Practice, EarlyView.
Climate change has reached unprecedented levels, causing frequent extreme events like droughts and fires. These changes are driving a sharp rise in extinction risk for mammals and threatening key Nature's Contributions to People (NCP) such as clean water, air quality, and climate regulation.

Climatic, biogeographic and ecological factors influence the spatial patterns of odd‐ and even‐year dominance in biennial European butterflies and burnet moths

Ecological Entomology, EarlyView.
250,000 observations of 7 annual, 11 biennial and 4 flexible lepidoptera species in the Alps and over 150,000 observations of 5 biennial species from Scandinavia were analysed. Maps show distinct patterns of different species that fly predominantly in odd or even years in the researched areas.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

Journal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Phantom citations: An empirical study of non‐existent and unverifiable references in scholarly literature

Journal of the Association for Information Science and Technology, Volume 77, Issue 10, Page 1287-1316, October 2026.
Abstract The integrity of scholarly communication depends critically on the accuracy and verifiability of cited references. Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be ...
