A global analysis of bird plumage patterns reveals no association between habitat and camouflage
Evidence suggests that animal patterns (motifs) function in camouflage. Irregular mottled patterns can facilitate concealment when stationary in cluttered habitats, whereas regular patterns typically prevent capture during movement in open habitats. Bird plumage patterns have predominantly converged on just four types-mottled (irregular), scales, bars and spots (regular)-and habitat could be dr...

Objective. To determine whether several topical compounds and other chemical entities are able to diminish the surface hydrophobicity of yeast cells. Method. Hydrophobicity of yeast cells was determined by binding styrene microspheres to the surface of untreated yeast or yeast pre-incubated with various substances with potential for cell surface modification. The degree of microsphere adherence...
متن کاملMolt and Plumage Patterns
Identification of birds not only means identifying the species of an individual, but also can include identifying its subspecies, sex, and age. Field identification of the age and sex of a bird can be important for studying many aspects of avian ecology and evolution, including life history evolution, reproductive ecology, and behavioral ecology. Ornithologists use a variety of characteristics ...
متن کاملPlumage color patterns of an extinct dinosaur.
For as long as dinosaurs have been known to exist, there has been speculation about their appearance. Fossil feathers can preserve the morphology of color-imparting melanosomes, which allow color patterns in feathered dinosaurs to be reconstructed. Here, we have mapped feather color patterns in a Late Jurassic basal paravian theropod dinosaur. Quantitative comparisons with melanosome shape and ...
متن کاملEvolutionary genetics: The evolution of plumage patterns
The identification and sequencing of a gene affecting melanin production in the bananaquit, a bird species notable for its polymorphic plumage colour, paves the way for much greater understanding of the evolution of plumage patterns in birds, and the developmental modulations involved in producing new patterns.
