| influence of social conditions in song sharing in the adult canary. | in songbirds, experience of social and environmental cues during a discrete period after birth may dramatically influence song learning. in the canary, the ability to learn new songs is assumed to persist throughout life. the aim of the present study was to investigate whether social context could guide changes in adult song. three groups of canaries were kept in different social and temporal conditions. results showed that the multiple hierarchical levels of the canary song structure were affec ... | 2009 | 19495816 |
| correcting for purifying selection: an improved human mitochondrial molecular clock. | there is currently no calibration available for the whole human mtdna genome, incorporating both coding and control regions. furthermore, as several authors have pointed out recently, linear molecular clocks that incorporate selectable characters are in any case problematic. we here confirm a modest effect of purifying selection on the mtdna coding region and propose an improved molecular clock for dating human mtdna, based on a worldwide phylogeny of > 2000 complete mtdna genomes and calibratin ... | 2009 | 19500773 |
| bdnf increases brdu-ir cells in the injured adult zebra finch hippocampus. | steroid-mediated cell proliferation, differentiation, and survival can be triggered by learning, experience, and brain injury. in the uninjured canary song system, testosterone induces cell proliferation that is blocked by an antibody to brain-derived neurotrophic factor (bdnf). however, little is known with regard to the effects of neurotrophic factors on injury-induced cell proliferation and incorporation. to address this, adult male zebra finches received bilateral hippocampal lesions by infu ... | 2009 | 19512953 |
| low-dimensional dynamical model for the diversity of pressure patterns used in canary song. | during song production, oscine birds produce large air sac pressure pulses. during those pulses, energy is transferred to labia located at the juncture between the bronchii and the trachea, inducing the high frequency labial oscillations which are responsible for airflow modulations, i.e., the uttered sound. in order to generate diverse syllables, canaries (serinus canaria) use a set of air sac pressure patterns with characteristic shapes. in this work we show that these different shapes can be ... | 2009 | 19518278 |
| determinants of organochlorine levels detectable in the amniotic fluid of women from tenerife island (canary islands, spain). | organochlorines (ocs) tend to accumulate in human tissues and can be measured in amniotic fluid (af). the detection of ocs in af samples reflects intrauterine exposure of human beings to these persistent organic pollutants. the present study was performed to evaluate the level of contamination of af by ocs in 100 pregnant women from tenerife island (canary islands, spain). gas chromatography/mass spectrometry (gc/ms) was used to identify and quantify the analytes, including 7 polychlorobiphenyl ... | 2009 | 19403124 |
| consort hypersensitivity pneumonitis. | to date, there is little information in the literature that hypersensitivity pneumonitis due to birds may occur without direct contact to birds. a 62-yr-old pensioner developed mild flu-like symptoms, fatigue and polyuria several hours after each meeting with his new female partner, either in hotels or his apartment. after divorcing from her ex-husband, who was a canary fancier, the female had moved into a bungalow approximately 6 months earlier. when the couple met for the first time at the bun ... | 2009 | 19407057 |
| prenatal environmental effects match offspring begging to parental provisioning. | the solicitation behaviours performed by dependent young are under selection from the environment created by their parents, as well as wider ecological conditions. here we show how mechanisms acting before hatching enable canary offspring to adapt their begging behaviour to a variable post-hatching world. cross-fostering experiments revealed that canary nestling begging intensity is positively correlated with the provisioning level of their own parents (to foster chicks). when we experimentally ... | 2009 | 19419982 |
