Linking the Ultraviolet Index to the “shadow rule” for sun protection: A theoretical model applied with a southern hemisphere example

open access: yesPhotochemistry and Photobiology, EarlyView.
We demonstrate the potential utility of the shadow rule and how it may be understood in relation to the UV Index. The shadow rule indirectly determines the sun's altitude by observing the length of a person's shadow during the course of the day. When the shadow cast by the sun on a horizontal surface is shorter than the height of the person casting the

Mixing oak and pine trees in Mediterranean forests increases aboveground hydraulic dysfunctions

open access: yesPlant Biology, EarlyView.
Mixing oak and pine trees enhances hydraulic impairments of all species, although diversity can mitigate drought stress during extended drought periods. Abstract Increasing tree species diversity in Mediterranean forests could reduce drought‐induced hydraulic impairments through improved microclimate and reduced competition for water.
