The historical biogeography of terrestrial gamebirds (Aves: Galliformes)
Whilst the phylogenetic relations of gamebirds are now well understood, there is a great lack of consensus on their biogeographical relationships. It has been suggested that the basal galliform clades, namely the megapodes from Australasia and the cracids from South and Central America, have their …

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 …

Small Intestinal Transporters in Two Species of Galliformes: Male and Female Turkey (Meleagris gallopavo) and Chicken (Gallus gallus)
… important avian species from the same order Galliformes. These differences can be used to improve feed efficiency and enhance the growth of both species.

A morphological phylogeny with a taxonomic revision of African species of Goniodes (Insecta: Phthiraptera: Ischnocera) sensu lato from the Galliformes (Aves)
… two distantly related groups of birds: Galliformes (pheasants, quail, partridges, etc.) and Columbiformes (pigeons and doves). Although there have been several cophylogenetic studies of lice at the species level, few studies have focused on such broad evolutionary patterns and major …

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 …

Reweaving the tapestry: a supertree of birds
… supertree the protocol was tested on the order Galliformes in order to determine the most efficient method of removing non-independent data. It was found that combining non-independent source trees via a “mini-supertree” analysis produced results more consistent with the input source data and, …

Population genetics, behavioural ecology and management of the Greywing Francolin Francolinus africanus
… than that for most birds, and for all other galliformes for which data are available. Thus, Greywing apparently have a high degree of population stability and large effective population sizes. Indirect estimates of migration and several significant allelefrequency differences between nearby …

The mechanisms underlying convergent evolution in the plumage patterns of birds
… waterfowl (Anseriformes) and gamebirds (Galliformes). Tracing the evolutionary trajectory of pattern evolution with Bayesian comparative modeling there was evidence for developmental constraint in pattern evolution. Adaptive explanations may also result in convergence. Cuckoo-hawk mimicry …

Taxonomy and phylogeny of red-tailed francolins (Genus Peliperdix)
… of francolins falls within the class Aves, order Galliformes, family Phasianidae and genus Peliperdix. These are small francolins consisting of three putative species (Peliperdix coqui, P. albogularis and P. schlegelii) that are largely allopatric. Two species (P. coqui and P. albogularis) are …

A study of the influence of sperm surface proteins on the activity of avian spermatozoa In-vitro and In-vivo

Parasite communities of wild turkeys (Meleagris gallopavo) in Colorado
… their parasite communities. Birds in the order Galliformes have a wide range of sizes and are generally non-migratory; thus they will not pick up parasites from different locations. I reviewed twenty six studies of 19 species of galliform birds and recorded the number of helminth species …

Responses of the Ocellated Turkey (Meleagris ocellata) to Human Disturbance
… 138 ha). In comparison to other similarly sized Galliformes, the Ocellated Turkey home range is quite large. The average movement rate also varied greatly between individuals (x ?x= 437 ± 264 m/h). A few individuals restricted their movements to intact forest only, while others spent all day in …

The evolutionary genetics of sexually selected plumage colour traits in the galliform birds
Extravagant male plumage traits in birds are a classic example of sexual selection. However we know very little about the units that selection is acting upon, the genes themselves – what are they and how are they influenced by sexual selection? In this study I focused on in the evolution and …
