Standard metabolic rate (SMR, ml O2 min−1) of captive Crocodylus porosus at 30 °C scales with body mass (kg) according to the equation, SMR = 1.01 M0.829, in animals ranging in body mass of 3.3 orders of magnitude (0.19–389 kg). The exponent is significantly higher than 0.75, so does not conform to quarter-power scaling theory, but rather is likely an emergent property with no single explanation. SMR at 1 kg body mass is similar to the literature for C. porosus and for alligators. The high… Expand

Ontogenetic comparisons of standard metabolism in three species of crocodilians
Standard metabolic rates (SMR) of three species of crocodilians were measured, and included individuals that ranged from 0.22 to 114 kg, and found differences in SMR among species are potentially related to behavioural differences in levels of aggression. Expand
Physiological constraints on body size distributions in Crocodyliformes
It appears that constraints on maximum size are shared across Crocodyliformes, perhaps through factors such as the allometric scaling of feeding rate versus basal metabolism with body size, and a model combining constraints from thermoregulation and lung capacity provides a physiological explanation for the larger minimum and average sizes of marine species.

Clutch, egg mass, and hatchling size influence organ size, and each factor should be accounted for in future studies exploring reptile morphology and physiology to assess environmental versus clutch contributions. Expand
Maximal Aerobic and Anaerobic Power Generation in Large Crocodiles versus Mammals: Implications for Dinosaur Gigantothermy
This study analyses maximal power output from measured aerobic and anaerobic metabolism in burst exercising estuarine crocodiles, Crocodylusporosus, and finds that ectothermic crocodiles lack not only the absolute power for exercise, but also the endurance, that are evident in endothermic mammals.

Coevolution of body size and metabolic rate in vertebrates: a life‐history perspective
It is argued that scaling exponents of these allometries do not themselves mirror one universal law of nature but instead statistically approximate the non‐linearity of the relationship between MR and body mass, and that an explanation based on the theory of life‐history evolution is the best way forward.

Allometric relations of respiratory variables in Amniota: Effects of phylogeny, form, and function.
Biological variables are frequently described by analyzing scaling relationships of the variable against body mass (MB). Respiratory variables are no exception and allometric relations for oxygenExpand
First evidence for a latitudinal body mass effect in extant Crocodylia and the relationships of their reproductive characters
This work provides the first evidence of a latitudinal effect on adult female body mass in crocodylians, as well as exploring the relationships between reproductive variables including egg mass, hatchling mass and clutch size. Expand
Metabolic scaling in animals: methods, empirical results, and theoretical explanations.
The methods of scaling analysis are reviewed, using examples for a range of traits with an emphasis on those related to metabolism in animals, and mechanistic explanations for metabolic rate that may explain the size- and temperature-dependence of this trait are proposed. Expand
Trends in embryonic and ontogenetic growth metabolisms in nonavian dinosaurs and extant birds, mammals, and crocodylians with implications for dinosaur egg incubation.
Embryonic and ontogenetic growth metabolisms are evaluated for extant altricial birds, precocial birds, mammals, and crocodylians to examine for trends in the different groups of animals and to provide a context for interpreting the results for nonavian dinosaurs. Expand
Embryonic metabolism of the ornithischian dinosaurs Protoceratops andrewsi and Hypacrosaurus stebingeri and implications for calculations of dinosaur egg incubation times.
The embryonic metabolisms of the ornithischian dinosaurs Protoceratops andrewsi and Hypacrosaurus stebingeri have been determined and are in the range observed in extant reptiles, and incubation times for 21 dinosaurs from both Sauischia and Ornithischia are predicted using a mass growth model based on conservation of energy.

Energetic costs of digestion in Australian crocodiles
Standard metabolic rate (SMR) and the metabolic response to feeding in the Australian crocodiles, Crocodylus porosus and C. johnsoni, are measured to reflect the substantial energetic demands that accompany the rapid growth of young crocodilians. Expand
Respiratory exchange and body size in the Aldabra giant tortoise.
Analysis of the relative proportion of the shell and other organs indicates that the shell forms about 31% of the body weight in adult T. hermanni but only about 18% in T. gigantea, which suggests that chelonians show no reduction in metabolic rate with increasing size. Expand

A meta-analysis of literature data shows that b is usually higher during active exercise than during rest, consistent with the metabolic level boundaries hypothesis, which predicts that maximal metabolic rate during exercise should be chiefly influenced by volume-related muscular power production.

It is proposed that differences in cardiopulmonary structure and function in non-avian reptiles may be responsible for the absence (in squamates) or presence (in crocodilians) of a strong training effect on aerobic capacity. Expand
Standard metabolic rate of the largest Australian lizard, Varanus giganteus
The intraspecific relationship between standard metabolic rate (VO2; ml hr−1) and body mass for Varanus giganteus is 0.0896 g0.90 at 25°C and 0.126 g0.96 at 35°C. The relationship between VCO2 (mlExpand
Metabolism of Squamate Reptiles: Allometric and Ecological Relationships
Estimating the metabolic rates of juvenile squamates from equations based on comparisons among species is invalid because there is significant variability among mass exponents among the 14 species that met the statistical requirements for analysis of covariance, and a common mass exponent cannot be assumed for intraspecific comparisons.
