Pheromones and other kinds of chemical communication underlie the behavior of all animals. Building on the strengths of the first edition, widely recognized as the leading text in the subject, this is a comprehensive overview of how pheromones work. Extensively revised and expanded to cover advances made over the last ten years, the book offers a thorough exploration of the evolutionary and behavioral contexts of chemical communication along with a detailed introduction to the molecular and neural basis of signal perception through olfaction. At a time of ever increasing specialization, Wyatt offers a unique synthesis, integrating examples across the animal kingdom. A final chapter critically considers human pheromones and the importance of olfaction to human biology. Its breadth of coverage and readability make the book an unrivaled resource for students and researchers in a range of fields from chemistry, genetics, genomics, molecular biology and neuroscience to ecology, evolution and behavior.

and an apical spiny dendrite that arborizes in the external plexiform layer, where they establish reciprocal dendrodendritic synapses with the secondary or lateral dendrites of mitral/tufted cells. See also Figure 9.14 for interactions between these cell types. Inputs from centrifugal axons bring top–down influence from other parts of the brain. The rostral migratory stream provides a continuous addition of new neuroblasts, which differentiate into granule and periglomerular cells. EPL, external

In mammals there are secretory glands in species-specific positions such as the flanks, around the eye, around the

others only mark externally and some use both mechanisms (Godfray 1994; Nufio & Papaj 2001: note their definition of marking pheromone is wider than HMP). In many species the Dufour’s gland is the source of the mark and the variation in the chemical profile of gland secretion may allow distinction of self- vs. conspecific marks. Females of six out of nine parasitoid species could distinguish between hosts parasitized by themselves and those parasitized by conspecifics, perhaps by individual
