The Editor’s Picks for 2018 have been released for the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology. According to the editorial team, the focus of this journal is on “the regulation of whole organismal function that requires the interplay of multiple organ and tissue systems.” The top comparative physiology articles of 2018 included: An article by Hersh et al., who provided evidence that little skates may be useful […]

In many mammals exposure to hypoxic conditions results in the release of a vasodilator called nitric oxide, which improves blood flow and protects oxygen delivery to tissues throughout the body. Diving animals appear to be unique in that some of their blood vessels stay constricted while they are diving even though they experience hypoxia. A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored […]
Hypoxic environments increase ventilation in animals. This helps to bring in more oxygen when environmental levels may be limited. With limited oxygen availability, the body turns to anaerobic metabolism, resulting in the production of lactate ions. These ions are known to indirectly stimulate breathing by lowering blood pH and were more recently discovered to directly stimulate the carotid body to increase breathing. For this reason, lactate ions are thought to […]
To wrap up my tour of physiology across the country, I am excited to attend the Comparative Physiology: Complexity and Integration Intersociety Meeting of the American Physiological Society. The meeting starts tonight with an opening lecture on reptile lungs. I can’t wait to tell you all about it!
I am pleased to showcase this year’s Comparative and Evolutionary Physiology Section (CEPS) award recipients at the Experimental Biology conference. Winners received their awards at the CEPS banquet last week. In earlier posts, I introduced this year’s Dr. Dolittle Travel awardee as well as Dr. Stanley Hillman, this year’s August Krogh Distinguished Lecturer. Here are the rest of award recipients: The New Investigator Award was earned by Dr. Allyson Hindle […]
Dr. Stanley Hillman was the recipient of this year’s August Krogh Distinguished Lectureship of the American Physiological Society’s Comparative and Evolutionary Physiology section. This award was named after Dr. August Krogh, born 1874 in Denmark. His dissertation focused on studying gas exchange in frogs. In 1908 he became an Associate Professor and later chair of the Department of Zoophysiology at the University of Copenhagen. He was awarded a Nobel Prize […]
Dr. Craig Franklin from the University of Queensland spoke yesterday about his research with crocodiles. After evaluating hundreds of recordings from telemetry instrumentation and satellite tags of the animals, the data showed that crocodiles regulate their body temperature much like fish. This means that crocodile body temperature is often dictated by their surrounding water temperature. Dr. Iskander Ismailov, a Research Assistant Professor from lab of Dr. Michael Friedlander at Virginia […]
