might allow sister-sister discrimination. The locations of the cues used in discrimination are not known. Egg-stage switches indicated that eggs or the comb, or their combination, are adequate for discrimination of a sister's comb from a nonsister's. For several reasons (7) we suspect that discrimination cues reside in the comb, not in brood members themselves, and are odors applied by the foun...
متن کاملDensity-dependent male mating harassment, female resistance, and male mimicry.
Genetic variation in female resistance and tolerance to male mating harassment can affect the outcome of sexually antagonistic mating interactions. We investigated female mating rates and male mating harassment in natural populations of a damselfly (Ischnura elegans). This damselfly species has a heritable sex-limited polymorphism in females, where one of the morphs is a male mimic (androchrome...
متن کاملVocal mimicry in male bowerbirds: who learns from whom?
Vocal mimicry is one of the more striking aspects of avian vocalization and is widespread across songbirds. However, little is known about how mimics acquire heterospecific and environmental sounds. We investigated geographical and individual variation in the mimetic repertoires of males of a proficient mimic, the spotted bowerbird Ptilonorhynchus maculatus. Male bower owners shared more of the...
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 کاملMahnob Hmi Ibug Mimicry Database (mhi-mimicry)
The experiments from which this database contains the recordings, were conducted with the aim of the analysis of human interaction, in particular mimicry, and elaborate on the theoretical hypotheses of the relationship between the occurrence of mimicry and human affect. The recorded experiments are designed to explore this relationship. The corpus is recorded with 18 synchronised audio and vide...
