Proprioception drives tension wood formation for autotropic straightening and postural control in trees

New Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...

Climate drivers of mesophyll conductance: temperature and water deficit alter CO2 diffusion and leaf anatomy in cotton

New Phytologist, EarlyView.
Temperature responses of photosynthesis, mesophyll conductance and stomatal conductance to water across Gossypium hirsutum cv Sicot 71, Gossypium arboreum, Gossypium bickii, Gossypium gossypioides and Gossypium sturtianum. Summary Mesophyll conductance (gm) limits CO2 delivery to Rubisco, yet its responses to temperature, heat and water deficit are ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

Plant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

Renaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral
