Climate adaptation and functional constraints drive pollen evolution in Apiales
New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Aletheia, revista de desarrollo humano educativo y social contemporáneoThis article aims to articulate philosophical knowledge to social work, linking it with the "Semillas y Raíces" (Seeds and Roots) Foundation located in Commune 4 (Altos de Cazucá) in Soacha, Colombia. The community processes that occur in this non-profit are emancipatory, due to their political and aesthetic factors. The political is viewed through the

New 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

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis
New Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.
