Fire regime change in western Tasmania between 1830 and 2025

open access: yesGeographical Research, Volume 64, Issue 1, February 2026.
Sketches by N.J.B. Plomley of George Augustus Robinson western Tasmanian expeditions in 1830 and 1833, undertaken to persuade Aboriginal nations of western Van Diemen’s Land to leave their ancestral lands. Geographic analysis of Robinson journal of this remote area provides unique insights in the changes in fire regimes that followed this tragic ...

Contribution of irreversible non-180° domain to performance for multiphase coexisted potassium sodium niobate ceramics

open access: yesNature Communications
Despite the dominance of lead-based piezoelectric materials with ultrahigh electric-field-induced strain in actuating applications, seeking eco-friendly substitutes with an equivalent performance remains an urgent demand.

Characteristics of water dissolved organic matter in Zoige alpine wetlands, China

open access: yesChemical and Biological Technologies in Agriculture
Abstract Background Dissolved organic matter (DOM) plays a significant role in the biogeochemical cycle of crucial elements in aquatic ecosystem. However, it is still not clear on the spectral characteristics of water DOM in different types of alpine wetlands, which have less anthropogenic influences and intensive ultraviolet radiation.

Chromosome fusions shaped karyotype evolution and evolutionary relationships in the model family Brassicaceae

open access: yesNature Communications
The ancestral crucifer karyotype and 22 conserved genomic blocks (CGBs) facilitate phylogenomic analyses in the Brassicaceae. Chromosomal rearrangements reshuffled CGBs of ancestral chromosomes during karyotype evolution.

Testing a General Theory for Optimal Flowering Time in Deciduous Perennial Plants as a Function of Growing Season Length

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Climate change affects both the start and duration of growing seasons, creating complex effects on optimal flowering timing that go beyond simple responses to earlier springs. Using optimal energy allocation theory, we found a nonlinear relationship between growing season length and optimal flowering time which was supported by two experiments with ...

Flax fibre: innovation and change in the early Neolithic: a technological and material perspective [PDF]

open access: yes
Flax (Linum sp.) was one of the first domestic plants in Neolithic Europe, providing a potential cultivable source of fibres for the first farmers. As the plant provides both oil and fibre, it is a matter of enquiry as to whether the plant was first ...
