Branchial osmoregulation in the euryhaline bull shark, Carcharhinus leucas: a molecular analysis of ion transporters
Assessment of branchial ion and acid-base regulatory mechanisms of C. leucas suggests that NHE3 and NKA together may be important in mediating branchial Na+ uptake in freshwater environments, whereas PDN and VHA might contribute to Cl-/HCO3- transport in marine and freshwater bull shark gills.

Is re-feeding efficiency compromised by prolonged starvation during aestivation in the green striped burrowing frog, Cyclorana alboguttata?
It is suggested that Green-striped Burrowing frogs (Cyclorana alboguttata) employs reduced digesta passage rates so as to maximize nutrient assimilation efficiency following prolonged food deprivation during aestivation. Expand
Arousal and re-feeding rapidly restores digestive tract morphology following aestivation in green-striped burrowing frogs.
During aestivation, the gut of the green-striped burrowing frog, Cyclorana alboguttata undergoes significant morphological down-regulation. Despite the potential impact such changes might have on theExpand
Staying cool, keeping strong: incubation temperature affects performance in a freshwater turtle
The results of the present study illustrate that even slight rises in the mean incubation temperature, over that observed in the wild, can impact upon a hatchling's performance. Expand
Physiological responses of ectotherms to daily temperature variation
The results suggest that the impact of increased thermal variability may favour some species while others are negatively impacted, and species that cannot compensate for increased variability by buffering growth and development will probably be most affected. Expand
The impact of prolonged fasting during aestivation on the structure of the small intestine in the green-striped burrowing frog, Cyclorana alboguttata
It is demonstrated that the intestine of an aestivating frog responds to prolonged food deprivation during aestivation by reducing in size, presumably to reduce the energy expenditure of the organ. Expand
Changes in cutaneous microbial abundance with sloughing: possible implications for infection and disease in amphibians.
Results of this study suggest that normal sloughing cycles could play a significant role in controlling the persistence and build-up of cutaneous microbes, including pathogens. Expand
Skeletal muscle atrophy occurs slowly and selectively during prolonged aestivation in Cyclorana alboguttata (Günther 1867)
The results suggest changes to muscle morphology during aestivation may occur when lipid reserves have been depleted and protein becomes the primary fuel substrate for preserving basal metabolic processes. Expand
Surviving the drought: burrowing frogs save energy by increasing mitochondrial coupling
Cyclorana alboguttata can survive in a dormant state for several years and it is proposed that energy efficiency is increased during aestivation, consistent with an increase in mitochondrial coupling efficiency. Expand
Functional and morphological plasticity of crocodile (Crocodylus porosus) salt glands
The results from this study demonstrate that the salt glands of C. porosus are phenotypically plastic, both morphologically and functionally and acclimate to changes in environmental salinity. Expand
