Although most physiological traits scale allometrically in unitary organisms, it has been hypothesized that modularity allows for isometric scaling in colonial modular taxa. Isometry would allow increases in size without functional constraints, and is thought to be of central importance to the success of a modular design. Yet, despite its potential importance, scaling in these organisms has rec...

Abstract Scomberoides commersonnianus is one of the commercially important fishes of the family Carangidae. In this study, 563 specimens (292 males, 247 females, and 24 sexually unknown ones) were collected from the north-west of the Persian Gulf. Length-weight relationships and condition factors were determined for each sex in four length classes within different seasons. In general, the growt...

Soft-sediment biogeochemistry is influenced by the bioturbation activity of benthic invertebrates. We investigated whether effect two macrobenthos bioturbators, Limecola balthica and Hediste diversicolor , on sediment oxygen uptake can be described allometric principles metabolic scaling with animal body size population biomass. Microcosms containing reconstructed populations to control density...

T he concept of scaling is now well established, and allometric analysis has become a standard tool for quantitative comparison of features between organisms of differing body size. This technique has been applied with great success in the field of comparative physiology, notably to respiratory physiology of mammals and of the avian egg, and the major findings have been succinctly reviewed by K...

This study was conducted to comprehensively survey the available literature on intravenous pharmacokinetic parameters in the rat, dog, monkey, and human, and to compare common methods for extrapolation of clearance, to identify the most appropriate species to use in pharmacokinetic lead optimization, and to ascertain whether adequate prospective measures of predictive success are currently avai...

Seed plants vary tremendously in size and morphology; however, variation and covariation in plant traits may be governed, at least in part, by universal biophysical laws and biological constants. Metabolic scaling theory (MST) posits that whole-organismal metabolism and growth rate are under stabilizing selection that minimizes the scaling of hydrodynamic resistance and maximizes the scaling of...

‘In the statistics of today, transformations . . . [aid] in the analysis of data by bending the data nearer the Procrustean bed of the assumptions underlying conventional analyses’ (Tukey, 1957). This letter is in response to Cawley & Janacek (2010), who take exception with our critique of a widely used procedure for estimating bodymass of dinosaurs and other giant animals in extinct lineages (...

Metabolism of living organisms is a foundation of life. The metabolic rate (energy production per unit time) increases slower than organisms' mass. When this phenomenon is considered across different species, it is called interspecific allometric scaling, whose causes are unknown. We argue that the cause of interspecific allometric scaling is the total effect of physiological and adaptation mec...

The traditional method for normalizing quantitative strength data is to divide force or torque by body mass. We have previously shown that this method is not appropriate for able-bodied children and young adults and that normalization using allometric scaling is more effective. The purpose of the current study was to evaluate the effectiveness of applying existing normalization equations for lo...
