Studies in Australian Tettigoniidae : The Phyllophorinae ( Orthoptera : Tettigoniidae ; Phyllophorinae )
A survey of Australian Phyllophorinae is presented. The entire fauna is represented by two species in two genera. Siliquofera grandis Blanchard, a species widely distributed in Papua New Guinea, is recorded from Iron Range, Queensland. Phyllophorella queenslandica Rentz, Su, Ueshima sp. nov. is described from Kuranda, Queensland and recorded from several localities on the Cape York peninsula. T...
متن کاملHeterochromatin heterogeneity revealed by restriction endonuclease digestion and subsequent C-banding on bovine metaphase chromosomes.
Conventional alkaline C-banding was found to be an effective additional step in restriction endonuclease banding to improve staining contrast and to reveal hidden changes in the heterochromatic blocks. Examples of these cases are demonstrated on the bovine chromosome set using Hinf I and Taq I endonucleases in the digestion experiments.
متن کاملPosition-dependent hearing in three species of bushcrickets (Tettigoniidae, Orthoptera)
A primary task of auditory systems is the localization of sound sources in space. Sound source localization in azimuth is usually based on temporal or intensity differences of sounds between the bilaterally arranged ears. In mammals, localization in elevation is possible by transfer functions at the ear, especially the pinnae. Although insects are able to locate sound sources, little attention ...
متن کاملFeulgen banding of heterochromatin in plant chromosomes.
Feulgen bands can be obtained at the sites of constitutive heterochromatin in the chromosomes of Anemone blanda, Fritillaria lanceolata and Scilla siberica, simply by means of a short or extended acid hydrolysis. Extended hydrolysis gives positive bands in A. blanda and F. lanceolata and negative bands in S. siberica. Short hydrolysis gives no bands in A. blanda and S. siberica but gives negati...
متن کاملUltrasound avoidance behaviour in the bushcricket Tettigonia viridissima (Orthoptera: Tettigoniidae).
The responses of female Tettigonia viridissima to simulated bat echolocation calls were examined during tethered flight. The insects responded with three distinct behaviours, which occurred at graded stimulus intensities. At low intensities (threshold 54 dB SPL), T. viridissima responded by steering away from the sound source (negative phonotaxis). At intensities approximately 10 dB higher, bea...
