Tracing Taonga Trajectories: A Methodological Framework for Indigenous Heritage Mapping

Journal of the Royal Society of New Zealand, Volume 56, Issue 1, February 2026.
Rangitāhua is a tupuna to Ngāti Kuri and represents the iwi's geographic and ancestral connection to the Pacific. Despite this millennium‐long ancestral tie, Ngāti Kuri's access to Rangitāhua has been severed for two centuries. Meanwhile, many European expeditions visited the islands, extracting and distributing natural history taonga across ...

The first comprehensive multilocus phylogeny of the lichenized genus Micarea (Ectolechiaceae, Ascomycota)

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Micarea is a crustose cosmopolitan lichen genus that belongs to the euascomycete class Lecanoromycetes. Recent molecular phylogenies on the genus based on one to three loci have mostly focused on Micarea s.str., including the type species M. prasina, and suggested that Micarea s.l. is paraphyletic.

Seed fossil record of Solanaceae revisited

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract The fossil record for Solanaceae has a complex taxonomic history, with many species originally described in the family being subsequently shown to belong in other plant families. In this work, we present an in‐depth analysis of the nightshade seed fossil record, which corresponds to the largest amount of fossil material for the family.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Future heatwave conditions inhibit CO2‐induced stomatal closure in wheat

New Phytologist, Volume 249, Issue 3, Page 1234-1252, February 2026.
Summary As global temperatures and the severity of droughts continue to increase, food crops will more frequently experience high vapour pressure deficit (VPD) during heatwave events. However, the interactive effects of rising atmospheric CO2 and high‐VPD heatwaves on crop water fluxes and yields are currently unknown.
