Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

open access: yesNew Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction

open access: yesNew Phytologist, Volume 248, Issue 2, Page 517-528, October 2025.
Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.

Urban developmental environments alter tadpole phenotypes depending on origin

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

The interplay between virus infection and water‐related stress is mediated by the plant metabolism of ascorbic acid

open access: yesNew Phytologist, Volume 247, Issue 1, Page 265-280, July 2025.
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection
