Physiological mechanisms of thermoregulation in reptiles: a reviewSpringer Science and Business Media LLC - Tập 175 - Trang 533-541 - 2005
Frank Seebacher, Craig E. Franklin
The thermal dependence of biochemical reaction rates means that many animals regulate their body temperature so that fluctuations in body temperature are small compared to environmental temperature fluctuations. Thermoregulation is a complex process that involves sensing of the environment, and subsequent processing of the environmental information. We suggest that the physiological mechanisms tha...... hiện toàn bộ
Gymnocypris przewalskii decreases cytosolic carbonic anhydrase expression to compensate for respiratory alkalosis and osmoregulation in the saline-alkaline lake QinghaiSpringer Science and Business Media LLC - Tập 186 - Trang 83-95 - 2015

Naked carp (Gymnocypris przewalskii), endemic to the saline-alkaline Lake Qinghai, have the capacity to tolerate combined high salinity and alkalinity, but migrate to spawn in freshwater rivers each year. In this study, the full-length cDNA of the cytosolic carbonic anhydrase c isoform of G. przewalskii (GpCAc) was amplified and sequenced; mRNA levels and enzyme activity of GpCAc and blood chemist...... hiện toàn bộ
Cardiac function of the leopard shark, Triakis semifasciataSpringer Science and Business Media LLC - Tập 160 - Trang 259-268 - 1990

The pressure difference between the cardinal sinus and the pericardium, and the transmural ventricular diastolic pressure at rest and during swimming in the leopard shark, Triakis semifasciata, was measured to characterize the mechanism of cardiac filling in chronically-instrumented fish and to evaluate cardiac responses to swimming. Echo-Doppler and radiographic imaging were also used to fully de...... hiện toàn bộ
Evaporative water loss: thermoregulatory requirements and measurements in the deer mouse and white rabbitSpringer Science and Business Media LLC - Tập 155 - Trang 433-436 - 1985
Kevin E. Conley
Using a physical model of the capacity for non-evaporative heat loss and measurements of metabolic heat production, I evaluated the evaporative requirements for thermoregulation in the deer mouse,Peromyscus maniculatus, and the white rabbit,Oryctolagus cuniculus. The physical limit to non-evaporative heat loss was calculated from the heat transfer properties of the two animals and expressed as a m...... hiện toàn bộ
In vitro characterisation of calcium influx across skin and gut epithelia of the Pacific hagfish, Eptatretus stoutiiSpringer Science and Business Media LLC - Tập 190 - Trang 149-160 - 2020
Chris N. Glover, Greg G. Goss
Although hagfishes osmoconform, concentrations of calcium in their extracellular fluids are maintained at levels lower than those of seawater. Ultimately, calcium homeostasis is a product of relative rates of influx and efflux into the animal, but little is known regarding these processes in hagfish. Using in vitro approaches, calcium influx across gut and skin epithelia of the Pacific hagfish, Ep...... hiện toàn bộ
