Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1441-1457, November 2025.
Fossil calibration reveals recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny indicated Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes.

Drivers of Centipede and Spider Diversity and Biomass Along an Elevation Gradient on Changbai Mountain, China

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Changes in density, diversity, and biomass with elevation differ between centipedes and spiders. Compared to centipedes, spiders are more strongly affected by environmental changes. Climatic variables act as the main drivers of centipede and spider density, diversity, and biomass, with local habitat–related factors being of secondary importance ...

Diversity Loss and Homogenization in Snake Communities in a Deforestation Hotspot

Diversity and Distributions, Volume 31, Issue 10, October 2025.
