Syringeal Structure and Avian Phonation
All analyses of syringeal function are based on indirect evidence, which may be obtained from dissections, manipulations of extracted syrinxes, models, analyses of physiological events associated with phonation, or analyses of the sounds produced. Expand
An hypothesis concerning the relationship of syringeal structure to vocal abilities
- A. Gaunt
- 1 October 1983
Syringeal complexity may not be an adaptation for plastic vocal behavior, but it is permissive of and probably prerequisite for such behavior. Expand

Muscle architecture in relation to function.
Three architectural patterns that deserve discussion are the classical arrangement of fibers in pinnate patterns, the more recent assumption of sarcomere equivalence, and the issue of compartmentation, all of which have potential functional implications. Expand
Rapid Atrophy and Hypertrophy of an Avian Flight Muscle
Eared Grebes use Mono Lake in eastern California as a rest stop during spring migration, but there the birds become obese by feeding on invertebrates and, if they have not already done so, molt, and most grebes remain several months until a decline in prey populations stimulates further migration.

The physiological basis of slow locomotion in chamaeleons.
- Y. Abu-Ghalyun, L. Greenwald, T. Hetherington, A. Gaunt
- Biology, Medicine
- The Journal of experimental zoology
- 1 March 1988
The results show that the slow locomotion of old world chamaeleons can, in part, be explained by the physiology, biochemistry, and fiber-type distribution of their muscles. Expand
Electromyographic and Pressure Events in the Nasolaryngeal System of Dolphins during Sound Production
In electromyography fine wires are inserted into muscles to measure their activity periods to evaluate the activity of various muscles of the nasolaryngeal system of dolphins during the production of sounds to correlate such movement with EMG and sound production. Expand
An assessment of the potential economic impact of Thrips palmi on horticulture in England and the significance of a successful eradication campaign.
Thrips palmi has not become established in England, yet its potential introduction represents a continuous threat to glasshouse ornamental and vegetable crops and there is uncertainty as to whether revenue from exports liable to carry T. palmi would be lost, if they were lost they would be the most significant contributor to the overall economic impact.

GENETIC EVIDENCE FOR EXTRAPAIR PATERNITY IN THE TUFTED TITMOUSE
The results suggest a rather low rate of extrapair fertilization in the study population; three of 34 nestlings could not be attributed to the attending male and two represented the entire brood in a nest attended by their mother and a nonparental male that appeared to be a close relative of the mother.
