MioVeg1: A Global Middle Miocene Vegetation Reconstruction for Climate Modeling

Paleoceanography and Paleoclimatology, Volume 40, Issue 11, November 2025.
Abstract Climate models require boundary condition information, such as vegetation and soil distributions because they influence the mean state climate, and feedbacks can significantly influence regional climate and climate sensitivity to CO2 forcing.

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.

Branch whorls of juvenile Araucaria araucana (Molina) Koch: are they formed annually? Los verticilos de juveniles de Araucaria araucana (Molina) Koch: ¿son formados anualmente?

Revista Chilena de Historia Natural, 2000
The growth of Araucaria araucana, like that of many other conifers, is characterised by the production of a monopodial stem with branch whorls. However, the periodicity of whorl formation in this species has not been subjected to systematic study.

Changes of wood anatomical characters of selected species of Araucaria- during artificial charring - implications for palaeontology

Acta Botânica Brasílica, 2017
Charcoal is widely accepted as evidence of the occurrence of palaeo-wildfire. Although fossil charcoal remains have been used in many studies, investigation into the anatomical changes occurring during charring are few. The present study analyses changes
