Avian evolution

Avian influenza A viruses (AIVs) pose a threat to global health because of their sporadic zoonotic transmission and potential to cause pandemics. Genomic surveillance of AIVs has become a powerful, costeffective approach for studying virus transmission, evolution, and dissemination, and has the potential to inform outbreak control efforts and policies.

Ebook "The biology of the avian respiratory system: Evolution, development, structure and function" is the avian respiratory system. The authors explain why the respiratory system of modern birds is built the way it is and works the way that it does. Birds have been and continue to attract particular interest to biologists. The more birds are studied, the more it is appreciated that the existence of human-kind on earth very much depends directly and indirectly on the existence of birds.

Reconstruction of ancestral karyotypes is critical for our understanding of genome evolution, allowing for the identification of the gross changes that shaped extant genomes. The identification of such changes and their time of occurrence can shed light on the biology of each species, clade and their evolutionary history.

The nearly neutral theory of molecular evolution predicts that the efficacy of natural selection increases with the effective population size. This prediction has been verified by independent observations in diverse taxa, which show that life-history traits are strongly correlated with measures of the efficacy of selection, such as the dN/dS ratio.

Recent large-scale whole genome sequencing efforts in birds have elucidated broad patterns of avian phylogeny and genome evolution. However, despite the great interest in economically important phasianids like Gallus gallus (Red Junglefowl, the progenitor of the chicken), we know little about the genomes of closely related species. Gallus gallus is highly sexually dichromatic and polygynous, but its sister genus, Bambusicola, is smaller, sexually monomorphic, and monogamous with biparental care.

The interferon-induced transmembrane (IFITM) protein family comprises a class of restriction factors widely characterised in humans for their potent antiviral activity. Their biological activity is well documented in several animal species, but their genetic variation and biological mechanism is less well understood, particularly in avian species.

Bird mitogenomes differ from other vertebrates in gene rearrangement. The most common avian gene order, identified first in Gallus gallus, is considered ancestral for all Aves. However, other rearrangements including a duplicated control region and neighboring genes have been reported in many representatives of avian orders.
