Genetic variation is described at 15 loci in 2 neotenic and 12 nonneotenic populations of red-spotted newts. Though high levels of genetic similarity (I = 0.990) were found among all populations, allele frequencies at six of the eight most polymorphic loci show significant heterogeneity across popul

The sexual behaviour of the red-spotted newt, No~ophthalmus viridescens, is described. The male can adopt one of two types of behaviour depending on the initial responsiveness of the female. If she is responsive, the male performs a brief lateral (or hula) display, at the end of which one or more sp
## Abstract Pheromones act as attractants and sexual stimulants in most vertebrates. For example, in redβspotted newts, __Notophthalmus viridescens__, female pheromones attract males, and male pheromones increase female receptivity. However, no studies have determined whether male vertebrates produ
