Dynamic sexual dichromatism in an explosively breeding Neotropical toad.
Sexual selection often promotes the evolution of elaborate colour signals in males, but the importance of sexually selected colour signals remains poorly studied in amphibians. We used reflectance spectrometry to document pronounced sexual dichromatism and dramatic colour change in Bufo luetkenii, a toad that breeds in large aggregations at the onset of the rainy season in Costa Rica. Our obser...
متن کاملOntogeny of Sexual Dichromatism in the Explosively Breeding Wood Frog
—Some species exhibit sex-specific color differences (sexual dichromatism) that are considered important for reproduction. The developmental timing of sexual dichromatism is largely unknown, particularly in amphibians, and is important for informing our basic understanding of sex-specific divergence in the physiology, anatomy, and ecology of species more broadly. Using a controlled laboratory e...
متن کاملSexual dichromatism in frogs: natural selection, sexual selection and unexpected diversity.
Sexual dichromatism, a form of sexual dimorphism in which males and females differ in colour, is widespread in animals but has been predominantly studied in birds, fishes and butterflies. Moreover, although there are several proposed evolutionary mechanisms for sexual dichromatism in vertebrates, few studies have examined this phenomenon outside the context of sexual selection. Here, we describ...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
