Evolution of avian olfaction

Following the scent of avian olfaction.

Researchers are gaining greater respect for a bird's ability to foElow its nose, a skill that may he@ it find food or navigate over Long distances It turns out Toucan Sam may not have been a liar after all. In the 197% the bright-billed cartoon spokesbird for Kall&s Froot bops cereal boasted in television ads that he could "follm his nose" to the d ' s '"deli-cious h i t smell." But amused biol...

Evolution of olfaction in non-avian theropod dinosaurs and birds.

Little is known about the olfactory capabilities of extinct basal (non-neornithine) birds or the evolutionary changes in olfaction that occurred from non-avian theropods through modern birds. Although modern birds are known to have diverse olfactory capabilities, olfaction is generally considered to have declined during avian evolution as visual and vestibular sensory enhancements occurred in a...

Olfaction.

The main and accessory olfactory systems have received considerable attention on the part of scientists and clinicians during the last decade, largely because of (a) quantum advances in understanding their genetically expressed receptor mechanisms, (b) evidence that their receptor cells undergo neurogenesis and both programmed and induced cell death, and (c) important technical and practical de...

Evolution of Insect Olfaction

Neuroethology utilizes a wide range of multidisciplinary approaches to decipher neural correlates of natural behaviors associated with an animal's ecological niche. By placing emphasis on comparative analyses of adaptive and evolutionary trends across species, a neuroethological perspective is uniquely suited to uncovering general organizational and biological principles that shape the function...
