Obtaining information on wild mammal populations has been a long-standing logistical
problem. However, an array of non-invasive techniques is available, including recently
developed molecular genetic techniques for the analysis of feces (molecular scatology).
A battery of non-invasive, molecular approaches can be used on feces, which in conjunction
with conventional analysis are potentially useful for assesing genetic structure,
demography and life history of mammals. Several technical problems reman before large-scale
studies of feces can be undertaken productively, but already studies are providing
insight into population subdivision, food habits, reproduction, sex ratio and parasitology
of free-ranging populations.
