Effects of insect herbivory on subalpine plant health


This is a field observation study that is part of a project investigating the effects of climate on plant-insect interactions. Since 2016 I have been collecting data on variation in apparent leaf damage to 9 focal subalpine wildflower species across two elevational gradients in Mt. Rainier National Park, and this year I will be using the MultispeQ to test whether photosynthetic ability differs among plants that have experienced different levels of insect herbivory.


Leaf Photosynthesis MultispeQ V1.0


Measures many photosynthesis-related parameters in <15 seconds, including:

  • Chlorophll Fluorescence: Phi2, PhiNPQ, PhiNO, NPQt, qL, LEF
  • Relative Chlorophyll: SPAD
  • Proton Motive Force: ECSt, vH+, gH+
  • Absorbance at: 450, 535, 605, 650, 730, 850, 880, and 940nm.
  • Leaf Thickness (in mm), angle, and cardinal direct...
