Association of reproductive traits with captive‐ versus wild‐sourced birds in trade

Conservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract The wildlife trade is a billion‐dollar global business, involving millions of people, thousands of species, and hundreds of millions of individual organisms. Unravelling whether trade targets reproductively distinct species and whether this preference varies between captive‐ and wild‐sourced species is a crucial question.

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

The Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Birds as indicators of early Holocene biodiversity and the seasonal nature of human activity at WF16, an early Neolithic site in Faynan, Southern Jordan

Journal of Quaternary Science, Volume 37, Issue 6, Page 1148-1163, August 2022., 2022
Abstract Birds are useful indicators of biodiversity. Their bones have been used for reconstructing the local environments and seasonality of human activity at Epipalaeolithic and early Neolithic sites in south‐west Asia. We consider the bird bones from WF16, an early Neolithic settlement in southern Jordan, currently located in an arid environment ...
