Investigating the validity of allometrically designed equations to estimate VO2max in Iranian boys

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: Cardiac respiratory system plays an important role in individuals’ health, promotion of patients’ life quality, and professional athletes’ performance. It is of great importance to measure it for exchange of inhaled gases during sports stress

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

The Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (

Allometric equations for the aboveground biomass of five tree species in China using the generalized method of moments

The Forestry Chronicle, 2018
Allometric equations are extensively used for estimating aboveground biomass. Although they have been developed for many tree species, there are many species for which no such equations exist.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

The Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Estimating tree biomass of sub-Saharan African forests: a review of available allometric equations

Silva Fennica, 2011
In response to the growing interest in estimating carbon stocks in forests, available allometric equations have been compiled for sub-Saharan Africa. Tree, sprout and stand volume and biomass equations were reviewed.

Three‐dimensional digital analysis of musteloid masticatory muscle architecture

The Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

A method for calculating the variance and confidence intervals for tree biomass estimates obtained from allometric equations

South African Journal of Science, 2011
The need for accurate quantification of the amount of carbon stored in the environment has never been greater. Carbon sequestration has become a vital component of the battle against global climate change, and monitoring and quantifying this process are ...

Allometric equations to assess biomass, carbon and nitrogen content of black pine and red pine trees in southern Korea

iForest - Biogeosciences and Forestry, 2017
A total of 74 Japanese black pine (Pinus thunbergii Parl.) and red pine (P. densiflora S. et Z.) trees were destructively sampled in southern Korea, which is severely affected by pine wilt disease (PWD).

Allometric Equations for Estimating the Carbon Sequestration in Rubber Plantations

Journal of Tropical Resources and Sustainable Science (JTRSS), 2015
Deforestation occurs due to agriculture and agroforestry. Since it can alter the whole ecosystem and can change regional and global climate, Malaysia is one of the membersof United Nation Framework on Climate Change (UNFCCC) which applies Kyoto protocol to curb this problem.

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.
