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...
متن کاملIdentification of Tibicen cicada species by a Principal Components Analysis of their songs.
Specific identification of three Tibicen cicadas, T. japonicus, T. flammatus and T. bihamatus, by their chirping sounds was carried out using Principal Components Analysis (PCA). High quality recordings of each species were used as the standards. The peak and mean frequencies and the pulse rate were used as the variables. Out of 12 samples recorded in the fields one fell in the vicinity of T. j...
متن کاملMorphology, bioacoustics, and ecology of Tibicen neomexicensis sp. n., a new species of cicada from the Sacramento Mountains in New Mexico, U.S.A. (Hemiptera, Cicadidae, Tibicen)
Tibicen neomexicensis sp. n., a new species of cicada found in the Sacramento Mountains of southcentral New Mexico, is described. Tibicen neomexicensis closely resembles Tibicen chiricahua Davis morphologically, but males of the two species have highly distinct calling songs that differ in phrasal structure, amplitude burst rates, and pulse structure. Unlike Tibicen chiricahua, male Tibicen neo...
متن کاملSocial Behavior and Communication in the Neotropical Cicada Fidicina mannifera (Fabricius) (Homoptera: Cicadidae)
We investigated signalling behavior in relation to social context in the cicada Fidicina mannifera. Four types of acoustic signals were recorded from males: songs, calls, low-amplitude songs, and disturbance sounds. Signal types were similar in frequency and fine temporal structure, but differed markedly in gross temporal structure. Songs and calls were the most frequently observed signals, and...
متن کاملA vector-based system for the differentiation of mouse embryonic stem cells toward germ-line cells
Objective(s):To culture thein vitro mouse embryonic stem cells (mESCs) and to direct their differentiation to germ-line cells; in present study we used a vector backbone containing the fusion construct Stra8-EGFP to select differentiated ES cells that entered meiosis. Retinoic acid was used to differentiate embryonic stem cells to germ cells. Materials and Methods: A fragment of Stra8 gene pr...
