Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Allometric scaling of marbofloxacin pharmacokinetics: a retrospective analysis [PDF]

, 2014
The association between physiologically dependent pharmacokinetic parameters (CLB, T1/2β, Vdss) 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 ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Allometric Equation for Biomass Estimation of Cordia africana Lam. in Tumata Chirecha Agroforestry Gedeo Zone: Implication for Sustainable Management and Climatic Change Mitigation [PDF]

, 2016
Species specific allometric equation is important for accurate net aboveground biomass estimation and quantifying carbon stock in living tree biomass of terrestrial ecosystems. This study was undertaken to develop species-specific allometric equation non-

Site-specific versus pantropical allometric equations: Which option to estimate the biomass of a moist central African forest? [PDF]

, 2014
Fewer data on tree biomass and allometric equations are available in African tropical moist forests than in the other tropical continents. When needing a biomass allometric equation, one thus faces the dilemma of using either a pantropical equation with ...

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Allometric Models of Aboveground Biomass in Mangroves Compared with Those of the Climate Action Reserve Standard Applied in the Carbon Market

Resources
The standardized methods used in carbon markets require measurement of the biomass and carbon stored in trees, which can be quantified through allometric equations.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Allometric equations, stem density and biomass expansion factors for Cryptomeria japonica in Mount Halla, Jeju Island, Korea

Journal of Ecology and Environment, 2014
This study was conducted to develop allometric equations and to determine the stem density and biomass expansion factor (BEF) for the estimation of the aboveground and belowground biomass of Cryptomeria japonica in Jeju Island, Korea.

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 (
