However, though short as titles are, they always contain a lot of connotations which are quite difficult to translate. Translation is substantially kind of cross-cultural information communication, and translation of song titles is no exception. Due to different origins, Chinese and Western cultures possess their own characteristics in cultural images, ways of thinking, and historical allusions, which should be considered when translating song titles.展开更多

In recent years, attention has gradually been paid on the metaphor study in the Chinese academic circles, and some domestic scholars have carried out research one after another, mainly through some daily expression, poetry, prose or novel to analyze and demonstrate the similarities and differences of love metaphors in Chinese and western culture. The new exploration of the role of metaphor in poetry and the cognitive mechanism was included, and it gained some achievements. The innovation of this paper is that it breaks the confinition to everyday expression, literature, combing with classic and modern songs in English and Chinese, to compare the love metaphor in English and Chinese songs.展开更多

The song is similar to those of the other species within the Turtur genus and likely reflects the adaptation to long distance signalling in tropical habitats. There is no study assessing individual variation of the Tambourine Dove song or for the possibility of identity coding through song features. Methods: We obtained recordings of 578 songs from 41 males within a population inhabiting montane forest in Cameroon between 2008 and 2018. Additionally, we analysed also recordings from automatic recorders working for a longer time during the year. Songs were analysed to get basic information about within- and between-individual spectro-temporal variation. Potential of identity coding and discriminant analyses were used to investigate if and how these songs may convey information about male identity. Results: The song of the Tambourine Dove is a very simple series of short, unmodulated whistles with low frequency and a narrow bandwidth. Measurements of single song features indicated either none or a weak potential for identity coding. The overall variation in song frequency characteristics was very low. However, the number of notes forming a song (and consequently the duration) had a similar variability both within- and between individuals. When using multiple song measurements discrimination analysis revealed a high potential for identity coding although it seems that the temporal pattern of the beginning of a song carries the most information about sender identity. The production of initial notes within a song has very precise, individually specific timing allowing for up to 96.7% correct recognitions of songs. Comparison of recordings from the same points but separated in time by over a month indicates that song parameters are individually stable over longer period. Conclusions: Despite having highly stereotyped and simple songs, Tambourine Dove males produce individually specific signals which have a great potential for recognition by rivals or mates. All Turtur doves have similar yet unique songs that are different to the songs of other pigeon species. This genus seems to be a perfect model for studying the trade-off between coding for species identity and individual identity in a non-learning bird species. The described method of individual recognition allows for nonintrusive population monitoring.展开更多

文摘Background:As one of the most elaborate and diverse sexual signals,bird songs are prominent among mate choice criteria.Females generally prefer mates with larger repertoire size,which promotes the evolution of song complex?ity.However,there are also some songbirds that have far simpler and less diverse vocalizations,which have not been the focus of scientific scrutiny.Most Phylloscopus warblers are accomplished singers with complex songs.In contrast,Hume's Warbler(P.humei) has extremely simple songs.In order to explore the song's function,its evolutionary sig?nificance and particularly to assess its possible relationship with parental investment,we studied mate choice of the subspecies P.h.mandellii in Lianhuashan National Nature Reserve,Gansu,China.Methods:We recorded body measurements and songs of breeding males and then explored their relationships with the date of clutch initiation,reasoning that the characteristics of males that are involved with early nesting activities reflect female mate preferences.We also recorded egg size and body measurements of nestlings to assess the rela?tionship between parental investment and mate choice.Results:We found that male wing and tail lengths were positively correlated with early clutch initiation as were songs characterized by short duration and rapid rise to maximum amplitude.We also found that early?breeding females did not lay large eggs,but produced more surviving young,which grew up faster.Conclusions:Female mate choice criteria in this bird include both visual signals and song characteristics.Our study supports the hypothesis that females may judge male quality from quite subtle differences.In order to reduce the risk of predation,a preference for such inconspicuous male characteristics may be partially driven by high vulnerability of this warbler to predators as a ground?nesting species.
