[pentachlorophenol poisoning in nestlings of canaries (serinus canarius) (author's transl)].	using binder twine of bales of straw as nesting material for canaries apparently resulted in a reduction of hatchability. however, the outstanding feature was the high mortality rate during the first week after hatching, with a peak on the fourth day and nestlings never growing any older than three months. other symptoms consisted in marked retardation of growth and poor growth of feathers. the adult birds presented a normal appearance. the most likely cause was the presence of pentachlorophenol ...	1979	425107
projections of a telencephalic auditory nucleus-field l-in the canary.	anterograde projections of a telencephalic auditory area - field l of the neostriatum - were traced in canaries, serinus canarius. field l was defined as the neostriatal projection of nucleus ovoidalis of the thalamus. using amino acid autoradiography, two efferent projections of field l and adjacent neostriatum were observed: (1) a projection to the medial and ventral borders of nucleus hyperstriatum ventrale, pars caudale (hvc) and (2) a smaller projection to medial paleostriatum augmentatum ( ...	1979	759444
animals as monitors of environmental quality.	the various species of domesticated and wild animals can be excellent monitors of environmental quality. although analyses of industrial air and water effluents and tests for toxicants in soils, plants, foods and feeds may provide some degree of predictability of environmental quality, the ultimate monitors are those organisms having metabolic activities that are comparable to man. if we closely observe animals that share our environment, like the coal miner's canary, they will alert us to unsee ...	1979	91256

experimental transmission of sarcocystis from icterid birds to sparrows and canaries by sporocysts from the opossum.	cowbirds (molothrus ater) and grackles (cassidix mexicanus) infected with muscle cysts of sarcocystis were fed to opposums (didelphis virginiana) and fecal sporocysts from the latter were given to sparrows (passer domesticus, family ploceidae), canaries (serinus canarius, family fringillidae) and ducks (anas platyrhynchos, family anatidae). asexual parasites were found in the endothelium of sparrows and canaries but not in ducks. when birds were kept 10 weeks or more after infection, muscle cyst ...	1978	98622
epizootiologic aspects of viscerotropic velogenic newcastle disease in six pet bird species.	pet birds of 6 species were exposed to a psittacine isolate to viscerotropic velogenic newcastle disease (vvnd) virus to evaluate the impact of vvnd in those species. species examined were the budgerigar, yellow-headed amazon parrot, canary, halfmoon conure, lesser hill mynah, and blackheaded nun. five of the 6 species were highly susceptible to infection with vvnd virus. canaries were relatively refractory to infection with the virus. contact birds of the same species developed infections almos ...	1978	629430

field trials of brodifacoum (wba 8119) against the house mouse (mus musculus l.).	the anticoagulant rodenticide brodifacoum was tested against house mice (mus musculus l.) infesting farm buildings. in six trials, treatment success was assessed from the results of census baitings conducted before and after treatment. with 0.005% brodifacoum in canary seed/corn oil bait, the control achieved ranged between 92.7% and 100%, mean 98.8%. two mouse populations were eradicated in 3 to 4 weeks but a few individuals survived each of the other four treatments which lasted 6 weeks. the e ...	1978	701785
three new species of penicillium.	three new species of microfungi belonging to the genus penicillium link ex fries are described and illustrated. all but one have been isolated from the atmosphere of las palmas, capital city of the island of gran canaria (canary islands, spain). they clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: penicillium hispanicum sp. nov., penicillium grancanariae sp. nov., and penicillium palmensis sp. nov.	1978	750938
[goethe's morphology definition and the problem of relationship of the cro-magnons to the primitive germans (carl gegenbaur)].	the problem of the teutons' origin has been considered to be open up to this day though some scientists have worked on this field since 1912. anthropologists and linguists as braun, feist, guntert, koppelmann, paudler and v.d. velden produced many evidences in favour of the hypothesis the teutons to be a mixture of the old european cro-magnons speaking an archaic ural-altaic idiom with the indo-europeans immigrating into europe from asia. the kelts may have a similar origin but they might includ ...	1978	357241
a new auditory area of the songbird forebrain: a connection between auditory and song control centers.	single unit microelectrode recordings followed by electrolytic lesions which mark the recording sites demonstrate that there is an auditory region of the songbird forebrain that is distinct from and superficial to field l, the primary auditory region of the telencephalon. the location of the superficial auditory area and its large cells suggest identification with hvc, the large-celled telencephalic nucleus which controls song in the canary.	1978	680043

role of auditory feedback in canary song development.	as in other songbirds, early deafening had drastic effects on the song of the roller canary, a cardueline finch, resulting in a song that was much simpler and more variable than the normal. the repertoire of the syllable types, of which the song is made, was reduced from 30 to a mean of 5.0. loud white noise was successfully used as a reversible method of cutting off auditory feedback from vocal behavior. although suffering permanent elevation of hearing thresholds, birds reared in noise to 200 ...	1977	838918
