This concluding chapter draws together the main themes of the book before summarizing the legacy of the pioneer guppy researchers. It identifies some areas where research is likely to be directed in future. These include the application of genomic tools and analyses of multi-trait evolution. There are three main conclusions. First, quality empirical work (such as behavioural observation and ecological recording) is of lasting value. The Trinidadian guppy system illustrates well how durable good data are. Second, investigations involving the guppy have led to significant advances in evolutionary ecology. It is a uniquely tractable vertebrate system. Lab studies can be dovetailed with field observations and manipulations. In addition, the guppy illustrates beautifully how changes in one trait, for example predator avoidance, impinge on others such as mating behaviour. Finally, the guppy system will continue to offer unrivalled opportunities to test theories in evolutionary ecology. The book concludes with a plea that the system be safeguarded.
