Sleep vs torpor

  I read an interesting review article published in Physiology comparing the low metabolic states of non-rapid eye movement sleep (NREM) and torpor. According to the article, all mammals experience NREM sleep patterns during which energy expenditure is decreased and body as well as brain temperatures decline. Animals that experience torpor (hummingbirds, arctic ground squirrels, some mice, bears, etc) have reduced metabolic rates and body temperatures that dip below baseline. NREM […]

Pediatric obesity in marmoset monkeys begins in the womb

A new review article published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored an interesting question: how do prenatal experiences along with the intrauterine environment impact the future development of pediatric and adult obesity in animals? Common marmosets (Callithrix jacchus) are New World monkeys that can spontaneously develop obesity early in life when living in captivity with high food availability and relatively low physical activity. Similar to […]

2018 Winners

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 […]

Seals have anti-inflammatory blood

Dr. Allyson Hindle from Massachusetts General Hospital in Boston, presented some interesting research on seals at the Experimental Biology conference this week in San Diego. Seals are known for being rather plump, which for humans often leads to inflammation and cardiovascular disease. In addition, seals undergo repeated bouts of hypoxia and reoxygenation during their dives, which is also known to promote inflammation and cardiovascular disease in humans. Her research team […]

Brine shrimp tolerance of environmental changes

Brine shrimp, Artemia franciscana, are neat little aquatic crustaceans. According to the University of Utah, these tiny creatures grow to about 1cm in length. They are a favorite meal choice of some migratory birds and they are often sold for use as food for fish destined for human consumption. Christopher Melendez, a graduate student in the lab of Dr. Casey Mueller at California State University San Marcos, presented his research on brine […]

2018 August Krogh Lecturer, Dr. Stanley Hillman

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 […]

What lurks in the water…

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 […]

Environmental impact on physiology

Several of the comparative physiology posters and talks presented at the Experimental Biology conference today focused on the impact of environmental changes on the physiology of animals. Here are some highlights: Rachel Heuer, a postdoctoral fellow at the University of Miami working with Dr. Martin Grosell, examined the effects of crude oil on heart function in mahi-mahi. As the Deepwater Horizon spill occurred when these fish were spawning, it is […]

Hagfish 101: How to eat a whale from the inside out

The Dr. Dolittle award is given to outstanding graduate students or postdoctoral fellows who are conducting comparative physiology research that they are presenting at the annual Experimental Biology conference. Applicants for the award are asked to submit guest blog posts describing their research. I am very pleased to share this guest blog post from this year’s Dr. Dolittle travel award recipient, Alyssa Weinrauch. Alyssa presented her research today the Experimental […]

Comparative Physiology @ Experimental Biology

I am printing my posters and planning my schedule for the 2018 Experimental Biology conference, which starts this weekend. This is no doubt the highlight of my year! I am looking forward to the comparative physiology sessions. Judging from the program, I think this is going to be a really exciting conference! This year’s August Krogh Distinguished Lectureship will be given by Dr. Stanley Hillman from Portland State University who […]
