Uridinediphosphate-glucuronosyltransferase (UDP-GT) Ontogeny and PCB Effects in Galliform Birds
Hepatic UDP-GTs are partly responsible for metabolism of the thyroid hormone, thyroxine (T4), in mammals, but little is known of UDP-GT activity in birds. To determine the ontogenic pattern of UDP-GT activity in precocial birds, we measured activity in Japanese quail (Coturnix japonica) liver at …

The evolutionary genetics of sexually selected plumage colour traits in the galliform birds
… in the evolution and genetics of colouration the galliform birds. Several novel loci were used to create a well resolved phylogeny of this group. This was then used to investigate and reconstruct the evolution of sexual plumage dichromatism. Four pigmentation genes were sequenced in an array of …

THE EVOLUTIONARY DEVELOPMENT OF CROWN GALLOANSERAE SKULLS: TRACKING CHANGES IN GALLIFORM AND ANSERIFORM CRANIAL DEVELOPMENT
… Galloanserae is a clade of birds that includes Galliformes (such as chickens and quails), Anseriformes (such as ducks and geese), and their close relatives. Galloanserae are distinctive in their very close relatedness and very distinct skull shapes. Most studies of galloanseran cranial disparity …

Parasite communities of wild turkeys (Meleagris gallopavo) in Colorado
Wild turkeys (Meleagris gallopavo) are large galliform birds, are commonly hunted birds, and they are non-migratory. Wild turkeys were originally found over most of the United States. In the early 1900s they experienced widespread population declines which are thought to have been caused by …

The historical biogeography of terrestrial gamebirds (Aves: Galliformes)
… It has been suggested that the basal galliform clades, namely the megapodes from Australasia and the cracids from South and Central America, have their origins in the northern hemisphere and have colonised the southern hemisphere more recently. Those in favour of a Northern Hemisphere …

Taxonomy, phylogeny and biogeography of francolins ('Francolinus' spp.) Aves: Order Galliformes, Family Phasianidae
… terrestrial gamebirds (Order Galliformes) that occupy diverse habitats ranging from dry/open/scrubby lowland and montane grasslands, bushveld and savanna/woodland to mesic montane/lowland forests and forest edges. Some francolins have complex distribution patterns and also are …

Systematic relationships in southern African Francolins as determined from mitochondrial DNA
… Francolins constitute the largest genus in the Galliform family Phasianidae. There is little accord concerning the taxonomic classification of its members. In the past, information on this group has been provided by morphological and palaeontological evidence. An investigation into the molecular …

Responses of the Ocellated Turkey (Meleagris ocellata) to Human Disturbance
… Turkey (Meleagris ocellata) is a Neotropical galliform bird of conservation concern because it faces a rapidly changing environment. The goal of this thesis is two fold: 1) to expand our understanding of the natural history of the Ocellated Turkey (Meleagris ocellata), and 2) to document the …
