Featuring: Ohio Physiological Society, Part 2

Here are some additional highlights from the 35th annual Ohio Physiological Society conference… Elizabeth Evans (Graduate Student, University of Dayton), Dr. David Goldstein (Wright State University), and Dr. Carissa Krane (University of Dayton) presented research examining the effects of multiple freeze-thaw cycles on Cope’s Gray treefrogs (Dryophytes chrysoscelis). Yes, that’s right, I said freeze-thaw cycles. These freeze tolerant animals build up glycerol in their bodies to help survive seasonal conditions […]

Birds may stay warm with the help of red blood cells

Researchers at Lund University in Sweden were interested in understanding how birds adapted to cold weather. Birds can’t turn up the heat in their birdhouse, so it is important for them to find physiological ways to stay warm. While they can store body fat and grow more feathers for insulation, metabolism is the primary way endothermic animals create body heat. Mitochondria produce cellular energy (ATP) but can also create heat […]

Extreme Fasting

While giant pandas roll in horse manure to stay warm in the winter (that’s a different story), other animals spend up to 8 months hibernating to conserve energy during times of reduced food availability and freezing temperatures. During their long winter’s nap, animals such as the Arctic ground squirrel and 13-lined ground squirrel go without food or water while at the same time avoiding muscle wasting – a rather impressive […]

Staying warm on a chilly day

Giant panda bears have a very unusual trick to staying warm. This unusual behavior was first noted by scientists at the Chinese Academy of Sciences in Beijing who observed a giant panda rolling around in horse manure in the Qinling mountains in central China during the winter of 2007. To see whether this was just a rogue panda or a more common behavior, scientists set up camera traps and observed […]

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 […]
