Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

New Phytologist, Volume 251, Issue 3, Page 1127-1142, August 2026.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Observing the invisible: X‐ray CT for plant–microbe interactions

New Phytologist, Volume 251, Issue 3, Page 959-966, August 2026.
Utility of X‐ray computed tomography (X‐ray CT) for visualising belowground plant interactions between multiple spatial scales and focal planes. Summary Plant–microbe interactions are inherently spatial, yet the physical structure of the soil and rhizosphere is rarely treated as a mechanistic variable in experimental design.

Combined phylogenetic and geographic data can predict plant–pest interactions with high accuracy

New Phytologist, Volume 251, Issue 4, Page 2107-2123, August 2026.
Schematic overview of the study pipeline. Summary Non‐native plant pests can pose major threats to biodiversity, with destructive ecological and economic consequences. The ability to predict future threats would allow limited resources to be concentrated on managing the most serious risks. We built a Bayesian model to predict hosts at risk from Agrilus,

Vulgar Minimisers in English and Spanish1

Transactions of the Philological Society, Volume 124, Issue 2, Page 291-313, July 2026.
Abstract In this paper, we investigated whether vulgar minimisers form a natural class in English and Spanish by evaluating (i) their similarities and differences with respect to non‐vulgar minimisers and (ii) whether vulgar minimisers are inherently negative in these languages.

ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

International Journal of Urban and Regional Research, Volume 50, Issue 4, Page 960-981, July 2026.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Dissecting the genetic basis of drought escape across multiple traits in colonizing Arabidopsis thaliana lineages

New Phytologist, Volume 251, Issue 1, Page 537-554, July 2026.
Cape Verde Islandspopulations experience seasonal drought and high humidity during the growing season, driving drought escape strategies relative to their Moroccan outgroup. Summary Drought response in plants is complex, involving integration across a range of physiological processes.
