Abstract

In this study, we focused on the use of acoustic activity as a function of time, rather than absolute cumulative emission counts. We hypothesized that the highest acoustic activity should occur near the steepest part of a typical vulnerability curve, that is, near its inflection point (P50), when most embolism is forming within a narrow range of water potential (Î¨). Therefore, the Î¨ at maximum AE activity should be correlated to a species' hydraulically measured P50.
