Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Undervalued Ecosystems: Ponds Boost Regional Macrophyte Diversity

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Ponds—depressional wetlands with ≤ 2 ha—are largely undervalued worldwide, despite serving as crucial diversity reservoirs. However, the extent to which ponds support diversity at the landscape scale is still underappreciated. Here, we investigate the contributions of ponds to macrophyte beta and gamma diversity in a subtropical wetland ...

Drivers of Hirola Antelope Diet Selection in Natural and Managed Habitat in Eastern Kenya

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Hirola (Beatragus hunteri) populations in eastern Kenya consumed 17 forage species, favoring the grass Chloris virgata and the forbs Commelina benghalensis and C. diffusa. Nutrient analyses showed that natural habitats offered higher phosphorus, magnesium, and digestibility, whereas managed sites provided more sodium, potassium, and crude protein, with
