Labiolingual thickness and cross‐sectional area in callitrichid incisors

Journal of Anatomy, EarlyView.
Many primates gouge to extract gums or saps from trees as part of their diet. Gouging callitrichid monkeys are characterized by lower incisors that are labiolingually thicker than non‐gougers, however, their incisors are not any larger in cross‐section. This difference may provide key insight into the gouging behavior of fossil primates.

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

Journal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Three‐Dimensional Effects of Two Minimally Invasive Surgically Assisted Rapid Palatal Expansion Techniques

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study evaluated, in three dimensions, the skeletal effects of two minimally invasive bone‐anchored techniques for surgically assisted palatal expansion, with and without pterygomaxillary disjunction (PD) and nasal septum disinsertion (NSD). Materials and Methods Thirty‐nine patients were retrospectively selected from two centres

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.
