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.

An alternative approach to allometric above‐ground woody biomass models using symbolic regression and terrestrial laser scanning

Ecological Solutions and Evidence
The accurate quantification of forest above‐ground biomass (AGB) is crucial for monitoring forest functioning and carbon stocks. Forest AGB maps are commonly derived from earth observation products and used in many downstream applications, such as global

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.

Modeling Aboveground Biomass for Improved Management and Productivity of Eucalyptus globulus Plantations in Northern Ethiopia

International Journal of Forestry Research
Estimation of aboveground biomass (AGB) is important for climate change mitigation, sustainable forest management, and carbon financing. Eucalyptus globulus has been grown extensively by smallholder farmers in Ethiopia, but very few studies have used ...

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.

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 (

The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Multiscale analysis of global variation in tree allometric relationships: parameter sets for global vegetation models

Environmental Research: Ecology
Global models of vegetation dynamics and remote sensing data products require allometric relationships governing trees’ size and shape to predict such quantities as vegetation spatial structure and biomass.
