...) on captive house sparrows in order to investigate the consequences of short-term dehydration on baseline and stress-induced corticosterone levels. As expected, water-deprived birds displayed higher plasma osmolality and haematocrit. Additionally, water-deprived birds had lower defecation rates, suggesting...

... adaptation Haematocrit Metabolism Notothenioids It is well documented that performance-enhancing strategies such as blood doping, the practice of boosting one's blood oxygen carrying capacity, are used by human athletes seeking a competitive advantage ( Momaya et al., 2015 ; Tokish et al., 2004...

..., the European starling ( Sturnus vulgaris ). We show that changes in haematocrit, body mass and wing length are independent of year and brood quality, while changes in haemoglobin concentration are higher in low-quality broods. Moreover, we also identify higher oxidative stress in low-quality year and second...

... not show post-training differences in sprint speed. Although acclimation to the laboratory environment and training explain some of our results, mechanistic explanations for these results correspond with the observed performance differences. After training, endurance-trained lizards had higher haematocrit...

...Magali Petit; François Vézina In small resident bird species living at northern latitudes, winter cold acclimatization is associated with an increase in pectoral muscle size and haematocrit level, and this is thought to drive the seasonal increase in summit metabolic rate ( Ṁ sum , a measure...

Although plasma volume and blood volume increased, mass-specific blood oxygen stores (total haemoglobin) fell during the study period...

...P. GALLAUGHER; M. AXELSSON; A. P. FARRELL; A.P. FARRELL Haematological variables were measured during aerobic swimming (45–55% of U crit ) and at critical swimming velocity ( U crit ) in acutely splenectomized and sham-operated rainbow trout. There was no correlation between haematocrit (Hct) and U...

... ), it follows that blood flow rates will also be lower. One might therefore predict that the relatively low haematocrits in hagfish ( Johansen et al . 1962 ; Forster et al . 1989 ) and lack of plasma albumins ( Manwell, 1963 ) would maintain a relatively low blood viscosity at low flow rates when blood tends...
