And also complex patterns of genotype-specific plasticity that are not easily explained by selection in more predictably variable environments:

She found clear consequences of these traits for tree growth at the hot edge of Fremont cottonwood's range:

Iris Garthwaite, now also a PMF at the USGS, dug into lab techniques and image analysis for quantifying leaf venation and stomatal traits doi.org/10.1002/ece3...

Her motivation to use new technologies and analyses in this system helps open up much larger-scale avenues for monitoring, predicting, and responding to climate change effects across the American Southwest!

And also that common spectral indicators of photosynthetic capacity decline as trees are planted in hotter temperatures than they have evolved to deal with:

She showed we can detect a tree's population of origin with high accuracy, even in a controlled environment:

Dr. Jackie Corbin, who now works on actually applying restoration principles with NRCS (as a PMF) used hyperspectral reflectance of Fremont cottonwood leaves growing in multiple common gardens and at home to detect genetic, environmental, and gxe effects on spectral traits doi.org/10.1111/pce....
