Effects of CO2, pH and temperature on respiration and regeneration in the burrowing brittle stars Hemipholis cordifera and Microphiopholis gracillima
Description: Hemipholis cordifera and Microphiopholis gracillima are burrowing brittlestars that differ in burrow architecture and oxygen obtaining strategies: M. gracillima actively ventilates a gallery while H. cordifera has a simple chamber and instead relies on oxygen being transported from arms exposed to the overlying water using hemoglobin in its water vascular system. To determine the possible effects of near future climate change on both species, in terms of metabolism and regeneration, they were exposed to current (25 °C & 28 °C) and elevated (32 °C) temperatures, as well as normal (8.1) and hypercapnia/lowered pH (7.8 & 7.6) in all combinations for six weeks.
