Can differences in xylem anatomy explain the contrasting responses of two olive cultivars to infection by the bacterium Xylella fastidiosa?
William Hammond, on an increasing threat to trees in the USA and elsewhere – drought and the embolisms it causes.
Results indicate that not all gases dissolved in the xylem sap are trapped within the ice in the stem of Scots pine and Norway spruce, during freezing.
The links between hydrometeorological conditions and vegetation distribution, functioning and survival.
Johnson et al. measure xylem embolism resistance and connectivity in roots of two co-occurring tree species in a semi-arid habitat, Quercus fusiformis and Sideroxylon lanuginosum.
