What are the anatomical and physiological strategies Polystichum acrostichoides uses to maintain photosynthesis and avoid hydraulic failure across the year?
Homoploid hybrid speciation – hybrid speciation without a change in chromosome number and facilitated by ecological divergence – is well known in angiosperms but rare in gymnosperms. To date, only two conifer species...
Actions aimed at reforesting arid areas around the world are becoming increasingly complex. In a recent study published in AoB PLANTS, Carevic et al. evaluated the physiological resistance to drought stress of Prosopis...
The genesis of agricultural practice marks one of the most important events in human history. Low atmospheric CO2 has previously been shown to limit the productivity of the wild progenitors of C3 and C4 founder crops...
Drought will become more severe in tropical rainforests as climate change continues. This could cause widespread tree mortality in these forests, unless the trees are able to acclimate and produce leaves that can...
Roots generally absorb water from the soil and transport it above ground to the stem, branches, etc. Where the soil is too dry for water to be absorbed by the roots, the roots might actually lose water to the soil and...
Root pressure can contribute to upward xylem water flow but it is difficult to measure directly. De Swaef et al. make continuous measurements of sap flow and stem diameter variations and combine them with a mechanistic...
The water-transport capacity of leaf venation is positively related to the leaf-lamina area, because the number and diameter of vein-xylem conduits are properly controlled to match the lamina area. Taneda and...
The dew point is ‘the temperature to which a volume of humid air must be cooled… for water vapor to condense into liquid water’, and is usually an early-morning or early-evening phenomenon in nature. OK, but, ‘what is...
