The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Research advances of Galliformes since 1990 and future prospects
Avian Research, 2018 Background Galliformes are widely distributed throughout the world and economically important to humans as domesticated animals or gamebirds. They are at a unique position for advancing knowledge and techniques of wildlife conservation as the barometer ...

The draft genome of the Temminck’s tragopan (Tragopan temminckii) with evolutionary implications
BMC Genomics, 2023 Background High-quality genome data of birds play a significant role in the systematic study of their origin and adaptive evolution. The Temminck’s tragopan (Tragopan temminckii) (Galliformes, Phasianidae), a larger pheasant, is one of the most abundant ...

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Floor Substrate Preferences of Chickens: A Meta-Analysis
Frontiers in Veterinary Science, 2020 Environmental enrichment promotes sensory and motor stimulation for species-typical behaviors, which in turn enhance animal well-being. For farmed Galliformes, housing systems often limit enrichment to bedding and litter, that simultaneously act as ...

Haptoglobins In Some Galliformes Birds
Poultry Science, 1977 In several groups of galliform birds (chicken, turkey, pheasant and guinea fowl) the presence and function of plasma haptoglobin (Hp) have been studied. Paper, acetate and starch-gel electrophoresis were carried out and two benzidine stain regions were observed when haemoglobin (Hb) was added to normal plasma (Hb-Hp complex and methemalbumin) besides ...

Suprageneric relationships of galliform birds (Aves, Galliformes): a cladistic analysis of morphological characters [PDF]
Zoological Journal of the Linnean Society, 2003 Of the basal clades of extant birds (Neornithes) the ‘landfowl’ or galliforms (Aves, Galliformes) are the most speciose. Cladistic analysis of more than 100 morphological characters coded at the generic level for most putative galliform genera confirms that the megapodes (‘mound builders’; Megapodiidae) are the most basal clade within the order.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
