... suggests the incorporation of hydrostatic pressure into a complex model of environmental tolerance, where energy limitation constrains biogeographic range, and into the metabolic framework for ecology and evolution. Biogeographic range limitation Heart rate Metabolic theory Respiration rate...

...Marjoleine M. H. Roos; Gi-Mick Wu; Patrick J. O. Miller ABSTRACT Respiration rate has been used as an indicator of metabolic rate and associated cost of transport (COT) of free-ranging cetaceans, discounting potential respiration-by-respiration variation in O 2 uptake. To investigate the influence...

... in food intake was related to variability in mitochondrial capacity: low intake (and hence growth failure) was associated with high leak respiration rates within liver and muscle mitochondria, and a lower coupling of muscle mitochondria. These observations, combined with the inability of fish with low...

... h at 6°C). Likewise, respiration rate during hypoxia showed a temperature dependence. An unusual finding was that cardiorespiratory status partially recovered during the latter stages of severe hypoxic exposure. We conclude that the cardiorespiratory responses to severe prolonged hypoxia in common...

...G. Parra; M. Yúfera SUMMARY Growth, energy content, ingestion and respiration rates and energetic efficiencies were measured in the larvae of two marine fish ( Solea senegalensis and Sparus aurata ) whose eggs have a similar diameter (approximately 1mm) and energy content (approximately 1J...

... the duration of a meal was greater for insects fed diet 7:7 than for those fed diet 21:21, although this was due entirely to meals lasting longer on the more dilute diet. However, the basal level of respiration rate was greater for insects fed diet 21:21 and, as a result, over the entire 2 h period, CO 2...
