The sister taxon relationships of these fossil taxa are robust to alternate phylogenetic hypotheses, and do not change when 'backbone' phylogenetic constraints based on recent morphological and molecular studies of higher-level avian phylogeny are imposed.
The phylogenetic tree [See Additional file 6, Figure S1] was constructed in Mesquite [ 122], based on recent phylogenetic analyses obtained for extant Mammalia [ 123], and non-avian reptiles [ 124- 130].

Based on recent history, he may be right.
We prioritized avian biodiversity 'hotspots' at continental and ecoprovincial scales based on: (1) avian species richness; and (2) habitat associations of 20 focal species.
Phylogenetic tree of the investigated species constructed based on consensus avian phylogenetic tool.
Although real-time RT-PCR based on the avian H5 gene was developed, the assay has not been evaluated on human clinical specimens (9).
