American Journal of Botany, Volume 113, Issue 1, January 2026.Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

American Journal of Botany, Volume 113, Issue 1, January 2026.Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

American Journal of Botany, Volume 113, Issue 1, January 2026.Abstract Premise Flower color diversity within communities is shaped by biotic and abiotic factors. Pollinators often prefer specific colors, and floral pigments also help protect against abiotic factors such as ultraviolet (UV) radiation, precipitation, and temperature.

Preliminary genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids
PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 245-258, January 2026.Societal Impact Statement The world‐wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America. In order to mobilise this genetic diversity in conventional breeding programmes, we need to be able to ...
