Vocal behaviour of the frog Eleutherodactylus antillensis on the British Virgin Islands
Article Abstract:
The vocal repertoire of male frogs (Eleutherodactylus antillensis) from Guana, Tortola and Virgin Gorda in the British Virgin Islands was examined. These frogs have three basic call types: courtship call, advertisement call and trill call. The characteristics of the last two calls were compared. The findings revealed that the spectral and temporal characteristics of these two calls from the male frogs taken from the three islands were similar, except that Guana frogs produced a higher average number of repeated notes in the trill. Evidence was also found suggesting that males may exploit the courtship calls of rivals to attract mates through interference.

Behaviourally mediated sex selection: characteristics of successful male black grouse
Article Abstract:
A field study of black grouse during their lekking period shows that male-male competition is important as well as female choice. Male grouse limit their behavioural repertoire when females are present and are more likely to fight when there are no females. Fighting allows the male grouse to enlarge his territory and gain a strategic position at the center of the lek. Males that succeed in courtship are likely to need larger territories so female preference is not the only factors affecting whether male grouse successfully breed.

Evolution of mate-choice copying: a dynamic model
Article Abstract:
A two-year dynamic model was developed to examine the conditions in which a mate-choice copying strategy may first evolve in guppies and black grouse. A starting population of pure choosers was assumed, which was invaded by a mutant female, which can copy during her first mating season. The model indicated that mate-choice copying may evolve when young females are poor at discrimination and have to know the appearance of high-quality males.
