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 ...

Cold‐blooded commerce: Characterizing and predicting trade in Australian squamates

open access: yesConservation Science and Practice, EarlyView.
Despite a national ban on native wildlife exports, Australian reptile species continue to appear in international trade. Using boosted regression trees, we found that large body sizes and taxonomic family, rather than color or patterning, best predicted trade presence. We identified 59 species likely to be targeted in the future, providing key insights
