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.

Les forêts de montagne de la Nouvelle-Calédonie [PDF]

, 2002
L'existence d'un gradient local de température plus prononcé près des montagnes isolées abaisse l'altitude moyenne de formation des masses nuageuses, créant ainsi des conditions propices au développement des forêts de montagne en Nouvelle-Calédonie à des

Testing key tenets of pyro‐ecophysiology: Indicators of drought response in relation to shoot flammability

American Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland

Archaeology in Oceania, Volume 60, Issue 3, Page 234-269, October 2025.
ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...

Whitby Jet Jewels in the Victorian Age [PDF]

, 2013
. During the middle nineteenth century, jet obtained from Whitby (England) was sought after due to its dark black color and hardness. This fossilized plant material was used in mourning jewelry, and Whitby hard jet was regarded among the best for carving

The stepwise rise of angiosperm‐dominated terrestrial ecosystems

Biological Reviews, Volume 100, Issue 5, Page 2131-2149, October 2025.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Scaling Up Bark Hydrology: Tree Size and Functional Traits Shape Water Storage in a Tropical Cloud Forest

Hydrological Processes, Volume 39, Issue 7, July 2025.
This study reveals that tree structure, especially bark volume, is the primary driver of bark water uptake in tropical montane cloud forests. Despite minor differences in intrinsic bark traits across species, whole‐tree water storage varies significantly.
