I am a Professor of Biology at Ashland University in Northeast Ohio where I teach courses in anatomy and physiology, vertebrate biology and marine biology. My research background is in marine biology and comparative physiology, while my current work centers on the evolution and development of the vertebrate lens and the function of proteins that prevent lens opacities, or cataract. I spend way too much time on my computer and thought I would leave some (pseudo) permanent mark on the web. I blog mainly about comparative physiology (especially vision), fishes (get it? - fish eye view?), my research and teaching and science happenings in Northeast Ohio. I have a long attachment to the Northern Outer Banks of North Carolina and plan to blog about that as well. Please leave a comment (even if exceptionally brief) so that I know my work is not in vain. Please?

Blood stem cells come in different types
by Mason Posner in A Fish Eye View
I love showing students new research that will ultimately lead to a revision in their textbooks. Hey, something has got to make purchasing a new edition every two to three years seem worthwhile. And it is even more fun when these research headlines come out as we are covering that very topic in class. A [...]... Read more »

Eat fish and acidify the oceans
by Mason Posner in A Fish Eye View
When teaching marine biology I warn my students that if they are there to just learn about sharks and dolphins they will be sorely disappointed, because only microscopic plankton have the biomass to really affect the oceans. Being an ichthyologist this always hurt a bit. A recent paper in Science has restored my faith that all [...]... Read more »

Limpets prepare for a hotter climate
by Mason Posner in A Fish Eye View
Changing climates have the potential to wreck havoc on living things, which are often adapted to very specific local temperatures. These changes can alter the structure and, therefore, the function of the tens of thousands of proteins that keep cells and their owners alive. Yet, the presence of living things in extreme environments ranging from [...]... Read more »
