Astragalus ecomorphology in Quaternary elephantids

Journal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, EarlyView.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

The morphological study of transcaspian marinka (Schizothorax pelzami) in Harirud and Dasht-e Kavir basins using the geometric morphometric technique

یافته‌های نوین در علوم زیستی, 2020
This study was conducted to understand the morphological variation of four populations of Schizothorax pelzami from Iranian inland waters. For this purpose, a total of 81 specimens were collected from the Bidvaz, Cheshmeh-Ali, Kalat and Aal rivers. After

Three dimensional geometric morphometric study of the Ethiopian <em>Myomys - Stenocephalemys</em> complex (Murinae, Rodentia)

Hystrix, the Italian Journal of Mammalogy, 2000
<strong>Abstract</strong> Geometric morphometrics was used to investigate the Ethiopian <em>Myomys - Stenocephalemys</em> complex, and to suggest possible explanations for differences in size and shape.

Macroscale Gradient‐Informed Neural Oscillation Topography in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by large‐scale disruptions in beta and gamma oscillations. Although subcortical beta power is an established biomarker for current adaptive deep brain stimulation (aDBS), it may not fully capture the global pathophysiological burden and the macroscale hierarchical reorganization of the ...
