Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

open access: yesConservation Science and Practice, EarlyView.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

open access: yesIbis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

A global perspective on the annual cycles of whimbrels

open access: yesIbis, EarlyView.
Comparative analyses are central to understanding broad‐scale patterns in avian ecology, yet their application is often constrained by fragmented and uneven data availability. Recent advances in tracking technology have generated unprecedented insights into shorebird movements, resulting in numerous studies on single populations or flyways.

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

open access: yesIbis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

Spectral Transforms as a Tool to Optimize Digital Phenotyping in Biological Images

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Modern livestock breeding has mastered genotyping. Genome‐wide association studies, genomic selection, and SNP arrays enable genetic merit prediction at lower cost. However, phenotyping remains the bottleneck, as manual measurement is slow, expensive, subjective, and unable to capture spatial or temporal trait organization. Digital phenotyping

Spot the difference: Turbidity‐driven plasticity and variation in spotted grunter (Pomadasys commersonnii) spot patterns

open access: yesJournal of Fish Biology, EarlyView.
Abstract Animal body markings such as spots, stripes and patterns play important roles in camouflage and visual communication. This study investigated phenotypic plasticity in the spot patterns of spotted grunter Pomadasys commersonnii, an estuarine‐dependent haemulid species.

Assessing the microstructure of simple rhamphothecae in chickens (Aves: Galliformes: Gallus gallus domesticus)

open access: yesJournal of Anatomy, EarlyView.
Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

open access: yesJournal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Characterisation of human hair follicle development

open access: yesJournal of Anatomy, EarlyView.
Schematic of hair follicle development in human skin. Hair follicle primordia of similar sizes, but different densities, are laid out across the skin. The distinction between terminal and vellus hair sites is not obvious at early stages of hair follicle development.
