Intractable Tangles in the Bird Family Tree
Rapid sequential speciation events can outpace the fixation of genetic variants, resulting in a family tree that lacks clear branching patterns. A new study of bird genomes reveals such an explosive super-radiation that may coincide with the mass extinction at the end of the Cretaceous period.
متن کاملReformatted planar 'Christmas tree' MR appearance of the endolymphatic sac.
A high-resolution three-dimensional Fourier transform technique and prototype bilateral dual phased-array surface coil technique was used to make inner ear structures visible on MR. Multiplanar reformatted images, parallel to the plane of the vestibular aqueduct, allowed viewing of the entire endolymphatic sac/vestibular aqueduct on one section, producing a "Christmas tree" shape. The reformati...
متن کاملHost-parasite arms races and rapid changes in bird egg appearance.
Coevolutionary arms races are a powerful force driving evolution, adaptation, and diversification. They can generate phenotypic polymorphisms that render it harder for a coevolving parasite or predator to exploit any one individual of a given species. In birds, egg polymorphisms should be an effective defense against mimetic brood parasites and are extreme in the African tawny-flanked prinia (P...
متن کاملBird Mite Infestation
Mites in the genus Dermanyssus are external parasites of birds, rodents and other mammals. The most common member of this group is the Chicken Mite that infests poultry roosts and wild bird nests. The chicken mite feeds primarily at night when the birds return the nest or roast area. They hide during the day in nearby cracks, crevices and other protected sites. These mites are known to infest h...
متن کاملCommentary on Bird and Klein
As Bird and Klein rightly observe, phonological thinking has lagged behind that in syntax and semantics: the metaphor of underlying representations being transformed via an ordered set of rules, long abandoned in syntax, is deeply ingrained in phonology. The cleanest break with this tradition is represented by declarative phonology, of which the current paper is an instance; indeed, the adoptio...
