The genetics of species differences within the genus Nasonia ASHMEAD 1904 (Hymenoptera: Pteromalidae)
… are assumed to posses an adaptive significance: courtship behaviour and wing size differences. The courtship behaviour consists of cyclically repeated series of head nods that are separated by pauses. The stereotypic performance allowed to split up the display into distinct courtship components. …

Behavioural and neural studies of male singing and female phonotaxis behaviour in crickets
… is achieved by the production of calling, courtship, and rivalry songs in male crickets and the recognition of the songs by conspecifics. Male crickets sing by rhythmically opening and closing the forewings to generate sound pulses and song patterns. The central command for singing is …

Diet, adaptation and the evolution of assortative mating in Ceratitis capitata
… tests, and also the quantification of male courtship behaviour. The genetic basis of the phenotypes associated with adaptation and sexual isolation was explored using transcriptomic sequencing and differential expression analysis of genes expressed in males from the two experimental regimes. …

The effect of gregarine parasite infections, age, and diet on calling song structure and mating behaviour in the Texas field cricket, Gryllus integer
… age, and diet have on the calling and mating behaviour of the male Texas field cricket, Gryllus integer. Male calling songs were recorded in the laboratory using a Digital Signal Processing Network. The song parameters measured were: pulse rate, pulse width, burst duration, pulses per burst, …

Central Expression of Sex Steroid Receptors during the Ring Dove (Streptopeliarisoria) Breeding Cycle
… model for studies in reproductive endocrine-behaviour interactions for many years. It shows bi-parental care and has a stereotyped breeding cycle. Androgen receptor and progesterone receptor immunoreactivity (AR-ir and PR-ir) were localised in the brain of male and female ring doves. Nuclear …

The biology of the Cape Weaver Ploceus Capensis with special reference to its polygnous mating system
… except at the nest. The territorial and courtship behaviour of the Cape Weaver are described and it is shown how aspects of the behaviours vary according to the time in the season and the pair-bond circumstances. A social hierarchy study on the species is discussed. Finally, the special …

Central mechanisms involved in the reproductive cycle of the ring dove (Streptopelia Risoria)
… to be involved in the expression of incubatory behaviour. Central progesterone receptors may serve to provide a general preparation for incubation. It was also suggested that PR in the POA, PPM and PLH are involved in mediating the expression of the aggressive behaviour which is apparent during …
