New Comparative Data on the Long Bone Microstructure of Large Extant and Extinct Flightless Birds
Diversity, 2022 Here, we investigate whether bone microanatomy can be used to infer the locomotion mode (cursorial vs. graviportal) of large terrestrial birds. We also reexamine, or describe for the first time, the bone histology of several large extant and extinct ...

Metric variation in the postcranial skeleton of ostriches,Struthio(Aves: Palaeognathae), with new data on extinct subspecies [PDF]
Zoological Journal of the Linnean Society, 2021 AbstractAs a result of numerous fossil and subfossil finds of ostriches, there is great demand for a comprehensive osteometric dataset for the living species and subspecies of the genus Struthio. We meet this demand by providing a set of > 100 measurements for a sample of 18 sexed skeletons, including all living and recently extinct species and ...

Journal of Biological Research - Thessaloniki, 2021 Amniote vertebrates share a suite of extra-embryonic membranes that distinguish them from anamniotes. Other than that, however, their reproductive characteristics could not be more different. They differ in basic ectothermic vs endothermic physiology, in

New Avian Hepadnavirus in Palaeognathous Bird, Germany
Emerging Infectious Diseases, 2017 In 2015, we identified an avian hepatitis B virus associated with hepatitis in a group of captive elegant-crested tinamous (Eudromia elegans) in Germany. The full-length genome of this virus shares

A lithornithid (Aves: Palaeognathae) from the Paleocene (Tiffanian) of southern California [PDF]
PaleoBios, 2014 The proximal end of a bird humerus recovered from the Paleocene Goler Formation of southern California is the oldest Cenozoic record of this clade from the west coast of North America. The fossil is characterized by a relatively large, dorsally-positioned head of the humerus and a subcircular opening to the pneumotricipital fossa, consistent with the ...

Ultrastructure of the eggshell of selected Palaeognathae species – a comparative analysis
Annals of Animal Science, 2014 AbstractThe study aimed at comparative analysis of the eggshell ultrastructure, indicating differences and similarities in its structure depending on the bird species. The study was carried out in ostrich, emu and rhea breeding flocks. The birds were kept under open system.

Birds and hard ticks (Acari: Ixodidae), with discussions about hypotheses on tick evolution
FAVE Sección Ciencias Veterinarias, 2017 The relationship between birds (Aves) and hard ticks (Ixodidae) was analyzed for the 386 of 725 tick extant species whose larva, nymph and adults are known as well as their natural hosts.
