(1) Unilateral post-ganglionic denervation in geese prevented the changes in [RNA] and [RNA]:[DNA] that occurred in the intact gland of birds given salt water for 24 hr; denervation had no significant effect in birds on fresh water throughout.
(2) I used to hear Canada geese sail overhead to a Stoke Newington reservoir behind where I lodged in my London days.
(3) Geese kept at 4.5 degrees C. trended toward greater fertility than geese housed but subjected to natural temperature variations.
(4) The prevalence of influenza varied greatly among the common waterfowl species: mallards 42%, black ducks 30%, blue-winged teal 11%, wood ducks 2%, and Canada geese 0%.
(5) But the company's permission to explore there was dependent on its impact on migrating birds, including pink-footed geese and whooper swans .
(6) Clinical signs in the live geese were weakness, lethargy, anorexia, emaciation and bile stained diarrhea.
(7) The live geese (155) were captured and moved to nearby freshwater wetlands where most apparently survived.
(8) In geese with one salt gland removed, no indication of compensatory growth of the remaining gland was evident in birds kept on fresh water for 24 days.
(9) The segmentum accelerans in geese is a constriction in the caudal end of the primary bronchus.
(10) Geese were trapped and blood samples were obtained in each of 4 consecutive years, 1966-69.
(11) The high prevalence of this condition in white-fronted geese suggested a genetic influence.
(12) Regional blood flow was measured using the radioactive microsphere method in unanesthetized Pekin ducks (Anas platyrhynchos) and bar-headed geese (Anser indicus) breathing 21, 10 and 5% O2.
(13) All species showed upper alimentary distress with mortalities occurring in the geese.
(14) Migratory ducks, Canada geese, and sandhill crane from the Pacific North American Flyway have been screened for Campylobacter spp.
(15) The ventilatory activity of the anterior and posterior groups of air sacs was simulated in unidirectionally-ventilated geese and the resultant flow of air in the mediodorsal secondary bronchi was used as an indicator of the route which air followed through the lung.
(16) These studies were carried out to compare certain hepatic microsomal drug-metabolizing enzymes of quail, ducks, geese, chickens, turkeys and rats.
(17) Although the introduction of these chemicals has been beneficial in reducing environmental contamination, some side-effects on wildlife have still been discernible and carbophenothion has now been withdrawn from use in Scotland owing to the deaths of wintering geese from carbophenothion poisoning.
(18) Fossil evidence suggests that these two groups of geese had a common ancestor 4-5 million years ago.
(19) Liver slices from geese, ducks (Aylesbury X Pekin) and chickens contained low UDP-glucuronyl transferase and high sulphate conjugation enzyme activities, whereas the reverse was found in Khaki-Campbell ducks.
(20) Psittacosis virus was not recovered from any of the birds examined, but a percentage of migrating geese had psittacosis antibodies.
