Experimental Biology – Day 3

I LOVE THIS MEETING! DAY 3 included several very interesting comparative physiology sessions. Eldon Braun (University of Arizona) spoke about how birds have a unique way to prevent water loss and thereby dehydration. In mammals, the kidneys are responsible for recovering water from the urine. However when birds are well-hydrated, the urine enters the colon and moves backwards up the gastrointestinal tract to facilitate water reabsorption prior to voiding the […]

Experimental Biology 2016 – Day 4

Still going strong…here are the highlights from several sessions held on Day 4: John Eme (California State University, San Marcos) presented data testing the effects of varying temperatures mimicking overwintering conditions on embryonic development of Lake whitefish. He found that indeed exposure to variable incubation temperatures between 2-8 deg C resulted in increased mortality. Moreover, the embryos hatched earlier and were smaller than animals exposed to constant temperatures. Nariman Hossein-Javaheri et al., (University […]

Experimental Biology 2016 – August Krogh Distinguished Lecturer: Dr. Jon Harrison

This year’s August Krogh Distinguished lecture, the highest award given to an accomplished Comparative Physiologist from the Comparative and Evolutionary Physiology section of the American Physiological Society was awarded to Dr. Jon Harrison, Arizona State University. Dr. Harrison gave an outstanding seminar in which he reviewed some of his major research discoveries. His work has included examining how insects tolerate various temperatures and how changes in the levels of atmospheric […]

Experimental Biology 2016 – Day 2

Today was a great day for trainees in comparative physiology! Here are some of the highlights from their sessions: Poster presentations: Alexis MacDonald et al., (Union College – Mentor Dr. Scott Kirkton) presented research showing that grasshopper skeletal muscles may use lactate for energy! Similarly, Dongying Wang et al., (Saint Louis University – Mentor Dr. Daniel Warren) also showed that skeletal muscle from painted turtles may use lactate. I guess it […]

Experimental Biology 2016 – Day 1

Today marked the official start of the Experimental Biology meeting for the American Physiological Society! The highest award the society offers a scientist is named in honor of Dr. Walter B Cannon, the physiologist (and 6th President of the society) who came up with the term ‘homeostasis’ in his 1930 book The Wisdom of the Body. This year’s award recipient is Dr. Amira Klip from the University of Toronto. In her […]

Heat stress in livestock

With the approach of summer, a timely study was published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on whether inflammation plays a role in heat stress-related complications in muscles. Heat stress is a major problem in the livestock industry. In the United States alone it is reportedly associated with a loss of approximately $158 billion annually in the swine industry. To cool off, swine seek shade and often mud baths […]
