... and averaged 190.79±70.13 ng g −1 dry mass. The effects of T max on fGCM levels did not carry over to the following morning, suggesting that very hot days are experienced as acute stressors. The study was conducted at Kuruman River Reserve (KRR), located in the southern Kalahari Desert, 28 km west of Van...

... (CWL) in birds. We compared CWL and intercellular SC lipid composition in 20 species of birds from desert and mesic environments. Furthermore, we compared covalently bound lipids with CWL and intercellular lipids in the lark family (Alaudidae). We found that CWL increases in birds from more mesic...

... brain and carotid blood temperature, using implanted data loggers, in five Arabian oryx ( Oryx leucoryx ) in the desert of Saudi Arabia. On average, brain temperature was 0.24±0.05°C lower than carotid blood temperature for four oryx in April. Selective brain cooling was enhanced in our Arabian oryx...

In this study we assessed the composition of covalently bound lipids of the avian SC and their relationship to cutaneous water loss (CWL) in two populations of house sparrows, one living in the deserts of Saudi Arabia and the other...

...Stéphane Ostrowski; Joseph B. Williams SUMMARY To test whether free-living desert ungulates employ heterothermy to reduce water loss, we measured core body temperature ( T b ) of six free-living Arabian sand gazelles ( Gazella subgutturosa marica ), a small desert antelope (12–20 kg) that lives...

... serves as a barrier to water vapor diffusion through the skin. We measured cutaneous water loss (CWL) in two populations of house sparrow Passer domesticus L., one living in a desert environment in Saudi Arabia, and another living in a mesic environment in Ohio, USA. We found that CWL rates at 30°C were...

...Stéphane Ostrowski; Joseph B. Williams; Khairi Ismael SUMMARY To test the idea that large, free-living, desert ungulates use heterothermy to reduce water loss, we measured core body temperature( T b ) of six free-ranging, adult Arabian oryx ( Oryx leucoryx ) during 2 years in the arid desert...

To understand the physiological mechanisms allowing these small organisms to survive and thrive in arid environments, we performed a phylogenetic...
