| song discrimination by male cicadas cicada barbara lusitanica (homoptera, cicadidae). | cicada barbara lusitanica males presented a stereotyped singing response behaviour when exposed to a playback of the conspecific song. males preferred (as measured by the time taken to sing) the conspecific signal to heterospecific songs that differed markedly in temporal pattern. manipulation of the gross temporal pattern of c. barbara calling song significantly reduced stimulus attractiveness. indeed, c. barbara males stopped responding to stimuli in which the temporal pattern approached the c ... | 2002 | 11948205 |
| patterns of acoustic variation in cicada barbara stål (hemiptera, cicadoidea) from the iberian peninsula and morocco. | field recordings of the calling song and of an amplitude modulated signal produced by males of cicada barbara from north africa and the iberian peninsula were analysed in order to assess the geographical acoustic variation and the potential usefulness of acoustic data in the discrimination of subspecies and populations. sound recordings were digitized and the frequency and temporal properties of the calls of each cicada were analysed. in all regions studied, peak frequency, quartiles 25, 50 and ... | 2008 | 18062838 |
| population structure of cicada barbara stål (hemiptera, cicadoidea) from the iberian peninsula and morocco based on mitochondrial dna analysis. | we assess the genetic history and population structure of cicada barbara in morocco and the iberian peninsula, based on analysis of the mitochondrial cytochrome b gene. the divergence between morocco and the iberian peninsula populations was strongly corroborated by the molecular data, suggesting genetically isolated populations with a low level of gene flow. the ceuta population from spanish north africa was more similar to the iberian populations than the surrounding moroccan populations, sugg ... | 2008 | 18062839 |
