Modelling tree height-diameter allometry of Chinese fir in relation to stand and climate variables through Bayesian model averaging approach

open access: yesSilva Fennica, 2021
Tree height-diameter allometry reflects the response of specific species to above and belowground resource allocation patterns. However, traditional methods (e.g.

Allometric growth in the frontals of the Mongolian theropod dinosaur Tarbosaurus bataar [PDF]

open access: yesActa Palaeontologica Polonica, 2022
Tarbosaurus bataar is a sister taxon of the well-studied theropod dinosaur Tyrannosaurus rex, and numerous fossils of this tyrannosaurid have been discovered in the Upper Cretaceous Nemegt Formation of Mongolia. Although specimens of different sizes of

Observation of Mammalian Similarity Through Allometric Scaling Laws [PDF]

open access: yes, 2002
We discuss the problem of observation of natural similarity in skeletal evolution of terrestrial mammals. Analysis is given by means of testing of the power scaling laws established in long bone allometry, which describe development of bones (of length ...

Centric Allometry: Studying Growth Using Landmark Data [PDF]

open access: yesEvolutionary Biology, 2021
AbstractThe geometric morphometric (GMM) construction of Procrustes shape coordinates from a data set of homologous landmark configurations puts exact algebraic constraints on position, orientation, and geometric scale. While position as digitized is not ordinarily a biologically meaningful quantity, and orientation is relevant mainly when some ...

Determination of the Biomass Allometry Equation and Carbon Calculation of Avicennia marina shrub in the Nayband Bay [PDF]

open access: yesبوم‌شناسی آبزیان, 2021
The study of biomass and carbon in mangrove forests is often performed by allometry methods. The allometry models in Mangrove trees are influenced by factors such as species, ecological conditions, and tree age.

Evolution of morphological allometry [PDF]

open access: yesAnnals of the New York Academy of Sciences, 2014
Morphological allometry refers to patterns of covariance between body parts resulting from variation in body size. Whether measured during growth (ontogenetic allometry), among individuals at similar developmental stage (static allometry), or among populations or species (evolutionary allometry), allometric relationships are often tight and relatively ...

Range-based techniques for discovering optimality and analyzing scaling relationships in neuromechanical systems [PDF]

open access: yes, 2009
In this paper, a method for decoupling the neuromuscular function of a set of limbs from the role morphology plays in regulating the performance of an activity is introduced.

Scale effects between body size and limb design in quadrupedal mammals. [PDF]

open access: yesPLoS ONE, 2013
Recently the metabolic cost of swinging the limbs has been found to be much greater than previously thought, raising the possibility that limb rotational inertia influences the energetics of locomotion.

Minimizing Bias in Biomass Allometry: Model Selection and Log‐Transformation of Data [PDF]

open access: yes, 2011
Nonlinear regression is increasingly used to develop allometric equations for forest biomass estimation (i.e., as opposed to the traditional approach of log‐transformation followed by linear regression).
