Selecting allometric equations to estimate forest biomass from plot- rather than individual-level predictive performance [PDF]
BiogeosciencesIn the context of global change, it is essential to quantify and monitor the carbon stored in forests. Allometric equations are mathematical models that predict the biomass of a tree from dendrometrical characteristics that are easier to measure, such as

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.

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 equations for hyper-arid desert plant species of AlUla County, Saudi Arabia
Carbon Balance and ManagementBackground Estimates of aboveground woody plant biomass in hyper-arid ecosystems have predominantly relied on allometric equations developed in more mesic habitats.

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.

Validation and refinement of allometric equations for roots of northern hardwoods
Canadian Journal of Forest Research, 2007 The allometric equations developed by Whittaker et al. (1974. Ecol. Monogr. 44: 233–252) at the Hubbard Brook Experimental Forest have been used to estimate biomass and productivity in northern hardwood forest systems for over three decades. Few other species-specific allometric estimates of belowground biomass are available because of the difficulty ...

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.
