Across the Pumice plain of Mount St. Helens, our research has focused mainly on understanding how plant sex differences influence ecosystem processes. Members of our lab are studying the leaf litter of male and female willows at a chemical level!<\/p>\n\n\n\n

To identify if male and female willows have unique chemical signatures, we measured condensed tannin, C and N, and a whole suite of compounds using Time of Flight Mass Spectrometry (TOFMS) in collaboration with the Center for Urban Waters at UW Tacoma.\u00a0 <\/p>\n\n\n\n

<\/div>\n\n\n\n

TOF Mass Spec readings give preliminary identification of the compounds in the willow samples. Of the 1,500 -1,600 individual compounds isolated in each sample, there were about 150 compounds that differentiate between the male and female willow samples at MSH!\u00a0 <\/p>\n\n\n\n
