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 ...

Bone histological evidence for posture‐related load transmission in the talpid pectoral girdle
Journal of Anatomy, EarlyView.Bone histology of the clavicle and scapula revealed distinct load‐bearing roles within the mammalian pectoral girdle associated with different forelimb postures. Hyper‐abducted moles exhibited an enhanced load‐bearing role of the clavicle, whereas the parasagittal shrew exhibited histological features consistent with the scapula acting as the principal

Restoration Ecology, EarlyView.Abstract Introduction Since European settlement, Australia's Wet Tropics bioregion has been extensively cleared, leaving a mosaic of rainforest fragments, crops, pastures, orchards, and human settlement. Fragment isolation leads to declines in faunal diversity and genetic variability, effects potentially exacerbated by climate change. Restoring habitat

Independent evolution of transcriptional inactivation on sex chromosomes in birds and mammals. [PDF]
PLoS Genetics, 2013 X chromosome inactivation in eutherian mammals has been thought to be tightly controlled, as expected from a mechanism that compensates for the different dosage of X-borne genes in XX females and XY males.

Contemporary Reflections on Substantial Kind Change in Avicenna
Theoria, EarlyView.ABSTRACT Contemporary metaphysics, and especially neo‐Aristotelian metaphysics, tackles many of the same problems as Avicenna did. One of these problems is the possibility of substantial kind change. For instance, is it possible for an animal to change its species?

The Anatomical Record, Volume 309, Issue 11, Page 3397-3415, November 2026.Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.
