Phylogenetics, biogeography and classification of, and character evolution in, gamebirds (Aves: Galliformes): effects of character exclusion, data partitioning and missing data
The combined‐data cladogram supports the hypothesis that basal lineages of galliforms diverged prior to the Cretaceous/Tertiary (K‐T) Event and that the subsequent cladogenesis was influenced by the break‐up of Gondwana.
A molecular phylogeny of the pheasants and partridges suggests that these lineages are not monophyletic.

The molecular phylogenetic analyses indicated that the pheasants and partridges arose through a rapid radiation, making it difficult to establish higher level relationships, but was able to establish six major lineages containing pheasant and partridge taxa.

An emerging phylogenetic picture reveals that relationships within Old World families are highly informative regarding the early dispersal and radiation of songbirds out of Gondwana.
Suprageneric relationships of galliform birds (Aves, Galliformes): a cladistic analysis of morphological characters
Although there are a number of important differences, especially with regard to relationships within the nonquail phasianoids, the results of this morphological phylogenetic analysis are broadly congruent with traditional classifications and existing molecular hypotheses of galliform phylogenetic relationships.
Coalescent models reveal the relative roles of ancestral polymorphism, vicariance, and dispersal in shaping phylogeographical structure of an African montane forest robin.

Natural freshwater wetlands are among the most threatened habitats on Earth. Effective wetland biodiversity conservation can not, however, be evaluated without fully understanding the roles of…
Systematics and biogeography of the family Scorpionidae (Chelicerata : Scorpiones), with a discussion on phylogenetic methods
This reconstruction identifies Opistophthalmus as the basal lineage of the Scorpionidae, rather than the sister-group of Scorpio, as well as demonstrating relationships among the scorpionid genera as follows.

SYSTEMATICS AND BIOGEOGRAPHY OF DOUBLE-COLLARED SUNBIRDS FROM THE EASTERN ARC MOUNTAINS, TANZANIA
Molecular analyses of 728 base pairs of mitochondrial DNA suggest that Moreau's Sunbird is a valid taxon and the sister species to Loveridge's Sunbirds, and a biogeographical hypothesis of speciation events within the N. mediocris species complex is proposed.
Effects of alien woody plant invasion on the birds of Mountain Fynbos in the Cape of Good Hope Nature Reserve
Dense infestations of mixed alien species in Restionaceous Tussock Marsh supported fewer nectarivorous birds, but more granivores and insectivores than did uninfested vegetation, and bird species more typical of woodland and thicket were found in dense mixed-alien infestation of this plant-species assemblage.
