Environmental enrichment improves mating success in fruit flies
Environmental enrichment, defined as housing conditions that include a combination of complex inanimate and social stimulation, has strong positive effects on brain and behaviour in various species. We extended previous studies to evaluate how enrichment affects mating success. In a series of experiments, we found that male fruit flies, Drosophila melanogaster, reared in an enriched environment...
متن کاملFemale preference for multi-modal courtship: multiple signals are important for male mating success in peacock spiders.
A long-standing goal for biologists has been to understand how female preferences operate in systems where males have evolved numerous sexually selected traits. Jumping spiders of the Maratus genus are exceptionally sexually dimorphic in appearance and signalling behaviour. Presumably, strong sexual selection by females has played an important role in the evolution of complex signals displayed ...

متن کاملFirefly Courtship: Behavioral and Morphological Predictors of Male Mating Success in Photinus greeni
Differences among males in their mating success constitute an important aspect of sexual selection (Darwin 1871), and many male sexual traits have been identitied that enhance male competitive ability or attractiveness to females (Andersson 1994). Male-biased breeding sex ratios are expected to intensify male–male competition and simultaneously cause females to become more selective due to redu...
متن کاملCourtship raises male fertilization success through post-mating sexual selection in a spider.
Courtship is well known for its positive effects on mating success. However, in polyandrous species, sexual selection continues to operate after copulation. Cryptic female choice is expected under unpredictable mating rates in combination with sequential mate encounters. However, there are very few accounts of the effects of courtship on cryptic female choice, and the available evidence is ofte...
