... pH levels (7.75 or 7.40). Survival, metabolic rates, whole-organism aerobic performance and cellular energetic capacity were assessed at the end of the exposure. Our results show that shrimp survival was negatively affected by temperature above 6°C and low pH, regardless of their origin. Additionally...

..., neither of the corticosterone traits differed between the A-selected and control lines. Thus, the experiment did not provide evidence that evolution of increased aerobic performance is facilitated by the modification of glucocorticoid levels. The results, however, do not exclude the possibility that other...

... showed increased performance under acute hypoxic test conditions, but not under normoxia. Our results highlight the detrimental effects of hypoxia on aerobic swim performance and sensory information acquisition, and the ability of fish to heighten aerobic performance through acclimation processes...

... performance. We studied plastic changes in organ mass and volume involved in aerobic respiration in response to acclimation to high altitude, and how those changes are matched with aerobic performance measured by . Adult deer mice born and raised at 340 m were acclimated at either 340 or 3800 m for a period...

... interlamellar spacing minimizes branchial resistance, it also limits lamellar number and results in a lower total gill surface area for the mako relative to tunas. The morphology of the elasmobranch gill thus appears to constrain gill area and, consequently, limit mako aerobic performance to less than...

... physiological and/or behavioural mechanisms underlying this improvement in aerobic performance after the first CAT will require further study. Nonetheless, the intra-individual repeatability of aerobic metabolism and U gt coupled with relatively small inter-individual variation in these variables signals...

...Gregory A. Russell; Enrico L. Rezende; Kimberly A. Hammond SUMMARY Previous studies suggest that genetic factors and acclimation can account for differences in aerobic performance( V̇ O 2 max ) between high and low altitude populations of small mammals. However, it remains unclear to what extent...

... only minimally. Finally, we argue that O 2 uptake is only one of a number of properties important to human aerobic performance. Humans differ from most mammals in one important respect relevant to V̇ O 2 max : exercise involves bipedal rather than quadrupedal locomotion. This use of two rather than...

Johnsen ABSTRACT We examined aerobic performance, organ and muscle mass and enzymatic activity in red junglefowl ( Gallus gallus ). We tested three models of performance limitation (central limits, peripheral...
