Demographic Processes: (2) Population Parameters
This chapter is concerned with some of the population-level consequences of lifehistory processes, in particular with population growth rates and migration. In the final section, I discuss sex ratios, a variable that frequently plays a crucial role in determining the costs and benefits of different behavioural strategies, but whose significance has often been overlooked.

- 1.In addition to the 23 species in Moore’s (1984) table, I have included black-and-white colobus among the transfer species on the evidence of Dunbar (in press), and the gelada among the non-transfer species on the evidence of Ohsawa and Dunbar (1984). I have also counted the hamadryas baboon as a non-transfer species: following Wrangham (1980), Moore seems to have misinterpreted the evidence that female hamadryas transfer between one-male units as implying transfer between ecological groups. In fact, it is clear from Sigg el al (1982) that female hamadryas transfer only between one-male units of the same band.Google Scholar
