Accurate quantification of forest carbon stocks is required for constraining the global carbon cycle and its impacts on climate. The accuracies of forest biomass maps are inherently dependent on the accuracy of the field biomass estimates used to calibrate models, which are generated with allometric equations. Here, we provide a quantitative assessment of the sensitivity of allometric parameter...

Allometric morphogenesis is the generation of form or pattern as a result of differential growth according to power-law relationships among the elements of a complex system. This phenomenon has been noted in a variety of fields for many years, in some cases for centuries, and yet it has never been related to the underlying determinants of the systems. By starting with fundamental properties of ...

The association between physiologically dependent pharmacokinetic parameters (CL(B), T1/2beta, Vd(ss)) of marbofloxacin and body weight was studied in eight animal species based on allometric equation Y = aWb, where 'Y' is the pharmacokinetic parameter, 'W' is body weight, 'a' is allometric coefficient (intercept) and 'b' is the exponent that describes relation between pharmacokinetic parameter...

IOLOGISTS have long directed attention to problems relating to the B determination of quantitative measures of body conformation and the genetic factors responsible for variation in conformation. Such variation in conformation hetween individual aninials within a species is due to differences in the relative proportions of the various parts to each other and to the animal as a whole. D’ARCY p t...

This paper presents a restricted overview of Fractal Physiology focusing on the complexity of the human body and the characterization of that complexity through fractal measures and their dynamics, with fractal dynamics being described by the fractional calculus. Not only are anatomical structures (Grizzi and Chiriva-Internati, 2005), such as the convoluted surface of the brain, the lining of t...

OBJECTIVE This study compared actual 6 minute walk test (6MWT) performance with predicted 6MWT using previously validated equations and then determined whether allometric modelling offers a sounder alternative to estimating 6MWT in adults aged 50-80 years. METHODS We compared actual 6MWT performance against predicted 6MWT in 125 adults aged 50-85 years (62 male, 63 female). In a second sample...

Assessing biomass dynamics is highly critical for monitoring ecosystem balance and its response to climate change and anthropogenic activities. In this study, we introduced a direct link between Landsat vegetation spectral indices and ground/airborne LiDAR data; this integration was established to estimate the biomass dynamics over various years using multi-temporal Landsat satellite images. Ou...

The aim was to investigate interspecies relationships between body weight (W) (kg) and various pharmacokinetic parameters for the anti-tumor agents amsacrine and its 4-methyl-5-(N-methylcarboxamide) analogue, CI-921, and examine which pharmacokinetic parameter, if any, might be used to predict the toxicity of these agents. Pharmacokinetic, plasma protein binding, and toxicity data were availabl...

From the available literature, the allometric scaling laws generally exist in biology, ecology, etc. These scaling laws obey power law distributions. A possibly better approach to characterize the power law is to utilize fractional derivatives. In this paper, we establish a fractional differential equation model for this allometry by using the Caputo fractional derivatives.
