Shape-shifting animals adapting to climate change

A recent review of the existing scientific literature found evidence suggesting that warm-blooded animals may be literally shape-shifting to adapt to climate changes. According to Allen’s rule, animals living in warmer climates have larger appendages than those living in cold climates, which helps increase the available surface area for heat loss to the environment. Such heat exchange mechanisms are very important in thermoregulation to avoid retaining excess heat. The authors […]

Q&A with Dr. Jon Harrison, Meredith Johnson, and Jordan Glass

We recently interviewed¬†Meredith Johnson¬†(graduate student), Jordan Glass (graduate student), and Dr. Jon Harrison from the School of Life Sciences at Arizona State University about the research they presented at the 2021 annual Experimental Biology conference. ¬† Q: You mentioned in one of your presentations that insects have an ‘unusual’ respiratory system. Can you explain how it differs from mammals?  Dr. Harrison: Insects exchange gases through blind-ended air-filled tubes called tracheae. There […]
