Primates: Scatter food throughout enclosure
A before-and-after study in 1994 in Georgia, USA (White et al. 1994) found that spreading food over a wider area reduced rates of aggression towards males from female ring tailed lemurs Lemur catta compared to when food was provided in a small area. When food was dispersed within a one metre radius, feeding males submitted to female aggression 42 times, within a two metre radius they submitted 38 times and within a four metre radius they submitted 19 times. Feed was scattered in a circular area to simulate a two dimensional food patch. Food patches with a radius of 1, 2, and 4m were created. All aggressive behaviours were recorded in nine adults and two infant lemurs from when the food was given to the end of the group’s feeding session. Each radius length was tested eight times, during different feeding times. (CJ)
