This book concerns the various ways that primates respond to
environmental change. By studying these patterns of responsiveness we
not only gain useful knowledge about the structural, physiological and
behavioural propensities of different species, but also acquire
important information relating to issues of contemporary concern, such
as conservation and the management of animals in the wild as well as in
various forms of captivity. For example, there is growing concern among
biologists and conser- vationists about the influence of habitat
destruction, such as logging, on the fitness and survival of wild
primates. There is also increased awareness of the need to improve the
care of primates in zoos and laboratories, including the enrichment of
captive environments. Further, because an increasing number of primate
species are becom- ing endangered, knowledge of their responsiveness to
new environ- ments is an essential requirement for effective breeding
programmes in captivity, and for the translocation and rehabilitation of
species in the wild. In theory, studies of many closely related species
are required in order to consider relevant evolutionary processes, as
well as to develop functional hypotheses about the adaptive significance
of various biological propensities and their interrelationships in the
short and longer terms.
