Astragalus ecomorphology in Quaternary elephantids

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of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Fluctuating asymmetry and environmental stress : understanding the role of trait history [PDF]

open access: yes, 2013
While fluctuating asymmetry (FA; small, random deviations from perfect symmetry in bilaterally symmetrical traits) is widely regarded as a proxy for environmental and genetic stress effects, empirical associations between FA and stress are often weak or ...

Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

Depigmented wing patch size is a condition-dependent indicator of viability in male collared flycatchers [PDF]

open access: yes, 2003
Honesty of sexual advertisement is thought to be the result of signalling costs. Because production costs of depigmented plumage patches are probably very low, their role as honest signals of individual quality has been questioned. Costs of bearing these

A Quantitative Approach to Record Skeletal Manifestations of Leprosy and Its Application to St Mary Magdalen Leprosarium, Winchester

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper presents and tests a new method for publishing and diagnosing leprosy‐related skeletal lesions while making available the leprosy‐related demographic data and pathology for St Mary Magdalen, Winchester (MMW). This method can facilitate interstudy comparisons of leprosy prevalence and severity by improving data comparability.
