Like a straw can collapse under the suction of a thirsty drinker, the xylem conduits in leaves can collapse as water potential declines during droughts (Figure 1). In collapsed conduits the water flow is limited or even completely interrupted, so plants must reinforce their conduits to resist crushing pressures. The thicker the conduit double cell…
New paper: Statistical inference methods for n-dimensional hypervolumes
Lab undergraduate student Dan Chen (now graduated!) just published a new methods paper on doing statistical inference on hypervolumes. It provides some important extensions to the hypervolume R package to do hypothesis tests, calculate p-values, etc. He and Alex Laini did the key development work. You can read it at the journal Methods in Ecology…
