Handling alters aggression and "loser" effect formation in Drosophila melanogaster.

In Drosophila, prior fighting experience influences the outcome of later contests: losing a fight increases the probability of losing second contests, thereby revealing "loser" effects that involve learning and memory. In these experiments, to generate and quantify the behavioral changes observed as consequences of losing fights, we developed a new behavioral arena that eliminates handling. We ...

Serotonin Modulates Circadian Entrainment in Drosophila

Entrainment of the Drosophila circadian clock to light involves the light-induced degradation of the clock protein timeless (TIM). We show here that this entrainment mechanism is inhibited by serotonin, acting through the Drosophila serotonin receptor 1B (d5-HT1B). d5-HT1B is expressed in clock neurons, and alterations of its levels affect molecular and behavioral responses of the clock to ligh...

The winner and loser effect, serotonin transporter genotype, and the display of offensive aggression.

Aggressive behaviour results from a complex interplay between genetic and environmental factors. Key modulators of aggression include the serotonergic system on the molecular level and experience in prior aggressive contests as an environmental factor. The aim of this study was to elucidate the effects of fighting experience on the display of offensive aggressive behaviour in adult male mice va...

Reinforcement Can Overcome Gene Flow during Speciation in Drosophila

Reinforcement, the strengthening of prezygotic reproductive isolation by natural selection in response to maladaptive hybridization [1-3], is one of the few processes in which natural selection directly favors the evolution of species as discrete groups (e.g., [4-7]). The evolution of reproductive barriers via reinforcement is expected to evolve in regions where the ranges of two species overla...

Testing Juvenile Mentality

tion to the book Dr. William Healy says, "For final diagnosis of the mentality of the individual, the Binet test score is simply one out of several main facts to be taken into consideration. Not even all mental abilities are represented in this system, to say nothing of their not being thoroughly tested at each age level, and many items of the physical background inevitably form part of the pro...
