Abstract
The commensal small non-volant mammals found in tradi-tional houses of Wayampi Amerindians have been studied in villages of Trois-Sauts on the upper Oyapock River (French Guiana). The Wayampi, also called Oyampi, are Amerindians living traditional lifestyles in the southeastern part of the Guianan Shield, especially in the Oyapock basin of French Guiana and in the Amapari basin of northernmost Brazil (Amapa) (Grenand et al. 1999 ). Today, many Wayampi live in close contact with modern occidental people, but a group of ca. 600 people (2010 census) remains relatively isolated on the upper Oyapock River. In particular, the Trois-Sauts com-munity, spaced along ca. 30 km on the left bank of the upper Oyapock, is still made up of hunters and gatherers who also tend small garden plots (Ouhoud-Renoux 1998)
