Papers
Acid-base physiology and CO2 homeostasis: Regulation and compensation in response to elevated environmental CO2
Colin J. Brauner,Ryan B. Shartau,Ryan B. Shartau,Christian Damsgaard,Andrew J. Esbaugh,Rod W. Wilson,Martin Grosell +6 more
- 01 Jan 2019
TL;DR: Fish that naturally live in such high CO2 environments appear to have an exceptional capacity for intracellular pH regulation, and the effect of fluctuating CO2 levels in both marine and freshwater environments may be especially problematic, and an area where more research is required.

Evolutionary and cardio-respiratory physiology of air-breathing and amphibious fishes
Christian Damsgaard,Vikram B. Baliga,Eric Bates,Warren W. Burggren,David J. McKenzie,Edwin W. Taylor,Patricia A. Wright +6 more
TL;DR: A detailed and re‐evaluated model of the evolution of air‐breathing among fishes that serves as a framework for addressing new questions on the cardiorespiratory changes associated with it is provided.

High capacity for extracellular acid–base regulation in the air-breathing fish Pangasianodon hypophthalmus
Christian Damsgaard,Le Thi Hong Gam,Dang Diem Tuong,Phan Vinh Thinh,Do Thi Huong Thanh,Tobias Wang,Mark Bayley +6 more
TL;DR: Pangasius has a much higher capacity for extracellular acid–base regulation during exposure to hypercapnia compared with other air-breathing fishes, such that generalizations across phylogenies may be difficult.
Learning to Air-Breathe: The First Steps
TL;DR: The physico-chemical constraints imposed by water and air are reviewed, and it is shown how that the advantages of combining control of ventilation and acid-base status are only available to the most obligate of air-breathing fish, thus highlighting promising avenues for research.

Hemoglobin isoform differentiation and allosteric regulation of oxygen binding in the turtle, Trachemys scripta.
TL;DR: This is the first extensive study on freshwater turtle Hb isoforms, providing molecular evidence for adaptive changes in O2 transport associated with acclimation to severe hypoxia and high ATP affinities indicate that, although ATP levels decrease in red blood cells of turtles acclimating to anoxia, the O2 affinity would remain largely unchanged.
