Defining Comparative Physiology

Today I interviewed Mr. Anthony J. Basile from Arizona State University who is working in the laboratory of Dr. Karen Sweazea. Anthony is a nutritionist and a third-year evolutionary biology PhD student whose research focuses on nutrition-related disease. He was scheduled to present his study at the 2020 Experimental Biology conference in San Diego last month. As with many plans these days, the conference was cancelled due to Covid-19. Can […]

The Effects of Ocean Acidification on California Sea Hare

Today’s guest blog entry comes from Rebecca Zlatkin. Rebecca ‘Becky’ Zlatkin was born and raised in Miami, FL and recently graduated from the University of Miami with a bachelor’s in Exercise Physiology and a minor in Biology. Previously a student at Miami Dade College’s Honor College, Becky came to the lab of Martin Grosell at UM’s Rosenstiel School of Marine and Atmospheric Science through the Bridge to Baccalaureate Program, a collaboration […]

What’s the buzz about bees?

We are excited to share the following interview with Dr. Lizzette Cambron, an NSF Graduate Fellow working in Dr. Kendra Greenlee’s laboratory at North Dakota State University. Dr. Cambron was scheduled to present her research at the 2020 Experimental Biology conference last month in a Comparative and Evolutionary Physiology session hosted by the American Physiological Society. As with many conferences, the meeting was cancelled due to Covid-19.  She has agreed […]

Physiology of diving animals: how do they deal with hypoxia?

Dr. Jose Pablo Vazquez-Medina (pictured at right), a comparative physiologist at the University of California – Berkeley, was scheduled to present several ongoing studies from his lab at the Experimental Biology conference last month. Dr. Vazquez-Medina is a member of the Comparative and Evolutionary Physiology section of the American Physiological Society. Although the conference was cancelled due to Covid-19, Dr. Vazquez-Medina has agreed to share his research with us.   […]

Worms turn bright blue with fright

Marine parchment worms have an unusual response to threats. They release a sticky bioluminescent mucus that glows blue. This physiological response is unique because the bioluminescence is constant as opposed to appearing in flashes like other marine organisms. In order to produce sustained light, the mucus would have to contain a source of energy. What they found was that the slime contained an iron protein called ferritin.  When the team […]

Highlights from the last day in Orlando

Today marked the final day of the 2019 Experimental Biology meeting in Orlando. As usual it was a great day for Physiology. Crupi et al., from the University of Messina and the Universita della Magna Grecia in Italy put up a poster presentation describing their research on how red blood cells respond to environmental toxins. Their research showed that isolated red blood cells from rabbits are more sensitive to venoms […]

Highlights from EB 2019

There were so many poster presentations on comparative and evolutionary physiology today at the 2019 Experimental Biology conference that it was impossible to see them all. Here are some highlights: Dr. Michael Hedrick from California State University – East Bay, presented his research on African cheetahs (Acinonyx jubatus) examining adaptations that cheetahs have evolved to supply their muscles with oxygen so efficiently, given they maintain the world record for being […]
