The father abandons his car and goes to look for help. He comes to the gate of a beautiful mansion, and he hears the roaring of an animal somewhere far away. The knocker on the door is made of gold and in the shape of a lion’s head. Before he can knock, the door swings open by itself, and the father sees a huge, empty hall luxuriously decorated. A little spaniel dog with a diamond collar greets him and shows him into a study, where there is a fire in the fireplace and some whiskey and sandwiches. Beauty returns to the Beast’s house with her father, and though she is afraid she also pities the Beast for his wildness and sorrow. The Beast presides without eating over a fabulous feast, but Beauty finds the Beast’s presence oppressive and feels herself as a sacrificial lamb.
After dinner the Beast suggests that Beauty remain with him and her father resume his legal battles. Beauty realizes that this is inevitable, and that she will be the “price of her father’s good fortune.” She decides to remain for her father’s sake.
The next day Beauty hears roaring in the hills and wonders if the Beast is hunting. She soon gets into a routine of whiling away the hours in comfort and silence and then talking with the Beast every night, and every night he kisses her hands just before they part. One day Beauty gets a phone call from her father, asking her to come to London, as he has regained his fortune. The Beast appears distressed and asks Beauty to return to him soon.
Beauty promises to come back before winter ends. She wants to kiss him but still feels he is so “different from herself” and so she cannot.
She takes a taxi off to London.
As part of the mating ritual, males of Drosophila species produce species-specific courtship songs through wing vibrations generated by the thoracic musculature. While previous studies have shown that indirect flight muscles (IFM) are neurally activated during courtship song production, the precise role of these muscles in song production has not been investigated. Fortunately, IFM mutants abound in Drosophila melanogaster and studies spanning several decades have shed light on the role of muscle proteins in IFM-powered flight. Analysis of courtship songs in these mutants offers the opportunity to uncover the role of the IFM in a behavior distinct than flight and subject to different evolutionary selection regimes. Here, we describe protocols for the recording and analysis of courtship behavior and mating song of D. Melanogaster muscle transgenic and mutant strains.
To record faint acoustic signal of courtship songs, an insulated mating compartment was used inside a recording device (INSECTAVOX) equipped with a modified electret microphone, a low-noise power supply, and noise filters. Songs recorded in the INSECTAVOX are digitized using Goldwave, whose several features enable extraction of critical song parameters, including carrier frequencies for pulse song and sine song. We demonstrate the utility of this approach by showing that deletion of the N-terminal region of the myosin regulatory light chain, a mutation known to decrease wing beat frequency and flight power, affects courtship song parameters.
