In many fruit fly species including Drosophila melanogaster, however, mating typically follows an extended period of courtship, which provides ample opportunities for females to inform males about their likelihood of mating. Our experiments indeed revealed that sexually immature females in both D. melanogasterand D. si- mulans showed responses to conspecific males that were distinct from those of sexually mature females. Furthermore, females＇ responses to conspecifie males were different from their responses to heterospecific males. Our data indicate that females＇ beha- vioral repertoire early in courtship can inform males about their probability of mating if they persist in courting. We hypothesize （i） that males can rely on behavioral feedback from females for optimally allocating their courtship efforts towards distinct female classes, （ii） that males may learn to modulate their courtship behavior based on specific feedback from females, and （iii） that fe- males may learn to alter their behavior towards distinct types of males in order to elicit the desired male response. Overall, we suggest that, although little explored, female behavior determines the dynamics of courtship and mating and can thus influence sexual selection and incipient speciation .展开更多

METHODS： A total of 694 enrolled subjects （218 male and 476 female） were divided into two groups： group A undergoing a 1200-Kcal BTCD, and group B undergoing a 1200-Kcal standard western diet. RESULTS： From TO （before treatment） to T1 （6 weeks after treatment）, BMI was lowered in group A from （32.33±5.51） to （31.96±5.56） kg/m2, and in group B from （31.62±6.29） to （31.36±6.47） kglm2. After treatment, patients in group A lost more weight （0.37±0.52） kg than group B （0.26±0.79） kg （P=0.0044）. From TO to TI, the mean lean mass of group A decreased from （16.48±5.50） to （16.27± 5.45） kg. In group B, mean lean mass decreased from （16.93 ± 6.49） to （16.44 ± 6.29） kg. The differ- ence was significant （P=0.0078）. CONCLUSION： The two diets could lead to lowerBMI, improve lean mass as well as eating behaviour and sense of hunger. However, the BTCD was signif- icantly better than the western standard diet.展开更多
