Introduction Today we are talking about structural equation models (SEM). There are lots of synonyms, sub-categories, and adjacent techniques that you may have heard before–covariance structure analysis, linear structural relations, […]
When I first developed the method to estimate canopy metrics from smartphone spherical panoramas, I used a somewhat convoluted workflow involving command line image manipulation, a plugin for ImageJ to […]
In this post, I will show some methods of displaying mixed effect regression models and associated uncertainty using non-parametric bootstrapping. This is kind of a follow-up to my previous post […]
An article I wrote about an expedition to collect wood frogs in the Alaska Arctic is now online at Alaska Magazine. I’ve included the teaser below, but check out the […]
The other day, I wanted to tweet out a map showing the distribution of some wood frog tissue samples compared to the entire range of the species. I’m not much […]
A short recipe for adventurous field science Take me to the photos! Step 1: Come up with a hair-brained scheme. My labmate Yara and I had been dreaming up the […]
Spherical panoramas can be tricky to stitch properly in dense forests, and especially when canopy elements are very close to the camera (which exaggerates the parallax). Fortunately, the issue attenuated […]
Our newest paper (pdf available on my publications page), led by Kaija Gahm is just out in the Journal of Experimental Zoology as part of special issue on herp physiology […]
Hemispherical photography is one of those tasks often prefaced by the statement, “How hard could it be?” I’m pretty sure I said something like this at the beginning of my […]
I’m thrilled to announce that the first of my dissertation chapters has just been published in Ecography. Update (Nov. 2020): And, I’m especially thrilled that our piece will be the […]
