Experimental Biology 2021: Q&A with Dr. Christian Damsgaard

We are delighted to speak with Dr. Christian Damsgaard who is currently an Assistant Professor at the Aarhus Institute of Advanced Studies & Section for Zoophysiology, Aarhus University, Denmark. Dr. Damsgaard is a member of the Comparative and Evolutionary Physiology section of the American Physiological Society and he presented his research “Active Blood Acidification Greatly Enhances Oxygen Supply to the Teleost Retina” at the 2021 Experimental Biology conference today. What initially interested you in studying […]

Cartilaginous fish need to regulate sulfate too

Seawater contains sulfate concentrations that are nearly 40 times those measured in plasma. Therefore, it is easy to see why fish would need to develop mechanisms to keep sulfate within a physiologically normal range. The kidneys of teleost fish have been known to excrete excess sulfate in the urine. However until now, it was not known whether the kidneys of cartilaginous fish do the same thing as their kidneys are rather complex. In a new […]
