Osteometry of Duck Species in Northwestern Europe—A Reassessment of Woelfle's (1967) Dataset

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study revisits and expands upon Elisabeth Woelfle's (1967) foundational analysis of bone morphology and osteometry, which has long been a key reference for zooarcheological identification of duck species in northwestern Europe. By examining Woelfle's unpublished measuring protocols and incorporating 523 newly measured specimens, we ...

open access: yesOikos, EarlyView.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...
