Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Water vapor and the dynamics of climate changes [PDF]

open access: yes, 2009
Water vapor is not only Earth's dominant greenhouse gas. Through the release of latent heat when it condenses, it also plays an active role in dynamic processes that shape the global circulation of the atmosphere and thus climate.
