The idiotype network hypothesis proposed by Jerne (1) has led to considerable interest in whether physiologic immunoregulation is accomplished by the interaction of receptor molecules and anti-receptors directed at unique idiotypic determinants. Another issue of importance, related to mechanistic questions, is whether exogenously administered anti-receptor antibodies might be used to manipulate...

D ow noad Fighting is dangerous, which is why animals choose to flee once the costs outweigh the benefits, but themechanisms underlying this decision-making process are unknown. By manipulating aggressive signaling and applying nitrergic drugs, we show that the evolutionarily conserved neuromodulator nitric oxide (NO), which has a suppressing effect on aggression in mammals, can play a decisive...

Bayesian methods provide an eeective tool for shrinkage in wavelet models. An important issue in any Bayesian analysis is the elicita-tion of a prior distribution. Elicitation in the wavelet domain is considered by rst describing the structure of a wavelet model, and examining several prior distributions that are used in a variety of recent articles. Although elicitation has not been directly c...

Crump interprets the stories, rather than simply recounting them. Her background as a research biologist, and her fi eld experience with native peoples, give her a broad perspective on the topic. She weaves a deft blend of summary and commentary, and often returns to emergent themes. Why do particular species appear in leading roles? Why do snakes and toads so often end up both as hero and vill...
