The current worldwide biodiversity crisis (Myers et al., 2000; Pimm and Raven, 2000) provides a natural laboratory for the study of behavioral flexibility (Tilman, 1999). Increasing temporal and spatial environmental variability and the effects of anthropogenic factors, in particular, habitat destruction, and subsequent habitat fragmentation and patchiness ( Jones, 1999a; Fukuda, 2004) are well documented for numerous primate species (Cowlishaw and Dunbar, 2000; Jones, 1983b, 1995b, 1996b, 1997c, 1999a; Harcourt et al., 2002; Clarke et al., 2002; Fukuda, 2004). This book relies heavily upon theoretical and empirical work on the causes and consequences of biodiversity from the fields of conservation biology and community ecology in an attempt to formulate and suggest tests of ideas appropriate for research at the individual level of analysis. From an evolutionary perspective, dispersal is of fundamental importance since it may counteract the effects of genetic drift by maintaining the connection between subpopulations and populations, preventing isolation.
