Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, Volume 250, Issue 6, Page 3716-3731, June 2026.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Soil properties and road proximity likely influence plant and bacterial traits and diversity more than habitat size in small urban greenspaces

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 878-891, May 2026.
The global decline in biodiversity can be partly ameliorated by sympathetic design of green spaces within urban environments. This includes roundabouts on road systems. This study utilised a combination of approaches to assess levels of plant and bacterial diversity in roundabouts of varying size, soil characteristics and habitat complexity.

Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health.
