Point distribution form model for spruce stems (Picea abies [L.] Karst.)
Journal of Forest Science, 2002 The paper deals with the construction of a point distribution form model for spruce stems. This model is based on the principal components analysis of variance-covariance matrix formed for the Procrustes residuals.

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of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...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.
