Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, Volume 101, Issue 6, Page 2920-2942, December 2026.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Per‐Channel Complex B1+$$ {B}_1^{+} $$ Mapping for Parallel Transmit Ultra‐High Field MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 12, December 2026.
Transmit‐field inhomogeneities beset ultra‐high field (UHF) MRI scans using single‐channel transmission or circularly polarised (CP) mode. Parallel transmission mitigates these artefacts but requires accurate subject‐specific per‐channel complex (magnitude and phase) B1+$$ {B}_1^{+} $$ maps. We explain the theory of per‐channel complex B1+$$ {B}_1^{+} $

A Critique of the Taxonomy of Subtribe Celmisiinae (Asteraceae: Tribe Astereae) With New Combinations in Pleurophyllum Hook.f. sens. lat. and Shawia hesperia (Heenan & Molloy) Heenan comb. nov.

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 4, December 2026.
This review is of the recently revised circumscriptions of the Pleurophyllum Hook.f. group and Shawia J.R.Forst. & G.Forst. of subtribe Celmisiinae, both centred in New Zealand. Recognition of Shawia is supported, and phylogenetic data recover seven well‐supported subclades treated as infrageneric sections.

English‐medium‐instruction offered by EFL teachers: Implications from a tier‐three Chinese undergraduate EMI programme

open access: yesReview of Education, Volume 14, Issue 3, December 2026.
Abstract Whilst EMI has been studied extensively across global higher education settings, the debate on EMI teachers' competence has still narrowly centred around English proficiency. Regarding EMI in China, most studies are conducted in top‐tier (tier‐one) universities, whereas little is known about EMI in low‐tier (tier‐three) universities.
