Evolution of acoustic communication in crickets: phylogeny of Eneopterinae reveals an adaptive radiation involving high-frequency calling (Orthoptera, Grylloidea, Eneopteridae).
Evolution of dominant frequencies in songs of Eneopterinae crickets was studied with respect to phylogeny. Two characters are optimized on the tree: the first describes the frequency resulting from the vibration of the harp (Fda), and the second is due to the vibration of other tegminal areas (Fdb). Fda was found to be relatively stable through the subfamily. Its low ancestral state is replaced...
متن کاملA new species of Cardiodactylus (Orthoptera: Grylloidea: Eneopterinae) from Singapore.
Cardiodactylus is a speciose cricket genus belonging to the subfamily Eneopterinae. One new species of Cardiodactylus from Singapore is described: Cardiodactylus admirabilis Tan & Robillard n. sp. Acoustic analysis is also performed on the male calling song. A key to species of Eneopterinae from Singapore is provided.
متن کاملSystematics of cryptic species of Lebinthus crickets in Mount Makiling (Grylloidea, Eneopterinae).
In the present study, we address Lebinthus cricket species from Luzon (Philippines) being sympatric in Mount Makiling. We describe Lebinthus puyos new species and redescribe the species Lebinthus sanchezi Bolivar, 1889 and select a neotype series. The species Lebinthus makilingus Otte, 2007 is synonymized under Lebinthus sanchezi. For each species we provide complete descriptions of morphology,...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولThe complex stridulatory behavior of the cricket Eneoptera guyanensis Chopard (Orthoptera: Grylloidea: Eneopterinae).
Crickets produce stridulated sounds by rubbing their forewings together. The calling song of the cricket species Eneoptera guyanensis Chopard, 1931 alternates two song sections, at low and high dominant frequencies, corresponding to two distinct sections of the stridulatory file. In the present study we address the complex acoustic behavior of E. guyanensis by integrating information on the pec...
