Dr Beckerman’s interests include most fields of ecological anthropology, as illustrated by his studies of peoples of lowland South America. He has conducted research on neotropical forest subsistence practices, warfare on and among tribal peoples, and human reproductive strategies. Most of his fieldwork has been with the Barí people of the Maracaibo Basin (Colombia-Venezuela) and the Waorani people of the Napo Basin (Ecuador.) One of his recent investigations explored partible paternity, the widespread belief that a child can have more than one biological father, and its consequences for child survivorship. Another modeled the conditions under which tribal peoples conserve their wild resources.
