Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

Oikos, Volume 2026, Issue 3, March 2026.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.

Catalysts for change: Museum gardens in a planetary emergency

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 401-410, March 2026.
Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.

Eocene belemnites from Hungary

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

The SCEC Community Rheology Model for the Southern California Lithosphere: Geological Framework, Ductile Flow Laws, and Preliminary Implications

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,
