Comparative genomics reveals insights into avian genome evolution and adaptation
TLDR
This work explored bird macroevolution using full genomes from 48 avian species representing all major extant clades to reveal that pan-avian genomic diversity covaries with adaptations to different lifestyles and convergent evolution of traits.
Complex distribution of avian color vision systems revealed by sequencing the SWS1 opsin from total DNA.
TLDR
The data support VS as the ancestral state in birds and show that UVS has evolved independently at least four times, indicating that interactions between predators and prey may explain the presence of UVS in Laridae and Passeriformes.
Differences in color vision make passerines less conspicuous in the eyes of their predators.
TLDR
Swedish songbirds' color badges are found to be significantly more conspicuous to other songbirds than to raptors and corvids in both coniferous and deciduous forests, consistent with an adaptive private communication system.
The phylogenetic distribution of ultraviolet sensitivity in birds
TLDR
It is shown that avian colour vision shifted between VS and UVS at least 14 times, and single nucleotide substitutions can explain all these shifts.
Evolution of ultraviolet vision in the largest avian radiation - the passerines
TLDR
The phylogenetic distribution of SWS1 cone opsin types in Passeriformes reveals a much higher degree of complexity in avian colour vision evolution than what was previously indicated from the limited data available.
Evolution of ultraviolet vision in shorebirds (Charadriiformes)
TLDR
It is confirmed that cysteine in the key amino acid position 90, characteristic of the UVS class, has been conserved throughout gull evolution but also that the terns Anous minutus, A. tenuirostris and Gygis alba, and the skimmer Rynchops niger carry this trait.
Ultraviolet vision and foraging in dip and plunge diving birds
TLDR
Evidence of extended UV vision only in gulls (Laridae) is found, and it is more probable that this trait is associated with their terrestrial foraging habits rather than piscivory.
Multiple shifts between violet and ultraviolet vision in a family of passerine birds with associated changes in plumage coloration
TLDR
Genomic DNA sequencing is used to determine VS or UVS affinity in fairy-wrens and allies, Maluridae, a large passerine family basal to the known UVS taxa, and character correlation analysis proposes that UVS vision is associated with shortwave-reflecting plumage, which is widespread in Malur Families.
RAPID POPULATION DIVERGENCE LINKED WITH CO‐VARIATION BETWEEN COLORATION AND SEXUAL DISPLAY IN STRAWBERRY POISON FROGS
TLDR
It is argued that changes in aposematic coloration may rapidly cause not only postmating isolation due to poorly adapted hybrids, but also premating isolation through shifts in mating behaviors.
