Beeswax corticosterone implants manuscript published
We applied a bit of arts and crafts to physiological ecology by making our own corticosterone implants out of beeswax following the lead of Quispe et al. 2015 who developed beeswax testosterone implants. With Scott Davies, Kendra Sewall, Ignacio Moore, Laura, Thomas, Ben Vernasko, and Kaan Kermaan, we tested several different doses of corticosterone in zebra finches and found the highest dose tested produced long-term (about a month) elevation in plasma corticosterone concentrations. Zebra finches that received the highest corticosterone dose also had greater fat, mass, but lower hematocrit than birds that received lower corticosterone doses. Our paper was recently published in General and Comparative Endocrinology! A link to the PDF can be found on the publications page.
