I came across a neat study published recently in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology which examined how bats arouse from hibernation, a period during which their body temperature and metabolism are low. To minimize the high energetic costs of warming up during arousal, bats use solar radiation or take advantage of fluctuations in the ambient temperatures (i.e. environmental).
Researchers studied hibernating long-eared bats (Nyctophilus…

The first session that I went to was called "RNASEQ approaches to understanding extreme physiological adaptations." Considering the Comparative and Evolutionary Physiology section business and dinner meeting was the night before, I was impressed at my ability to make it to an 8:00am session the following morning.
The first seminar from Dr. Brooke C Harrison (Univ. Colorado, Boulder) was on "Extreme cardiac growth and metabolism in the Burmese python after feeding." He spoke about how the cells of…
