One of my thesis chapters reviewed examples of increases in appendage size relative to body size (and thus changing overall shape, hence the term "shape-shifting"). This paper sparked a fair amount of media attention when it was published in Trends in Ecology and Evolution (see Media appearances tab). We then got the opportunity to respond to comment that was published about our paper, to discuss how allometry gets accounted for when evaluating Allen's rule.
I also had the opportunity to write a News and Views article for Nature Climate Change about a paper published by them in 2022, looking at body size decreases in tree swallows.
To investigate shape-shifting, I made use of a 3D scanner to be able to extract surface area measurements of bills (rather than estimates of bill surface area, generated from linear measurements). My second paper focused on using 3D scanners on museum specimens, to ensure the method was repeatable between observers and to understand how manual measurements differed from the 3D scan-based measurements. It was published in Journal of Avian Biology.
My other thesis chapters are currently in the process of being published, but I have uploaded one on bioRxiv.
