Deep learning in sex estimation from photographed human mandible using the Human Osteological Research Collection

open access: yesLegal Medicine
Sex estimation is a necessary part of forensic and osteological analyses of skeletal human remains in the construction of a biological profile. Several skeletal traits are sexually dimorphic and used for skeletal sex estimation. The human mandible and morphological traits therein have been long used for sex estimation, but the validity of using the ...

On the conflict between science and ethics: the case of the moggel, Labeo umbratus (Teleostei: Cyprinidae) from South Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent molecular evidence showed that Labeo umbratus comprises two allopatrically distributed genetic lineages, a northern lineage confined to the Orange‐Vaal River system where this species was originally described and a southern lineage with three geographically separated haplogroups (western, central and eastern) distributed across multiple
