Climate adaptation and functional constraints drive pollen evolution in Apiales

open access: yesNew 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 ...

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1544-1560, March 2026.
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Tropical Rainforests Exhibit Higher Multidimensional Stability Than Rubber Plantations Despite Lower Resistance to Temperature Anomalies

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Rapid rubber plantations (RB) expansion in Southeast Asia raises critical questions about regional ecosystem stability. We compared stability between monoculture RB and diverse tropical rainforests (RF) using 37 years of satellite‐derived gross primary productivity across three metrics: long‐term temporal stability, resilience, and resistance ...
