The role of acoustic signals for species recognition in redfronted lemurs (Eulemur rufifrons)

Table 1 Parameter estimates for the Linear Mixed Models (LMM) on the influence of the different playback stimuli and the genetic distance between species on the percentage of time spent looking towards the speaker for redfronted lemurs tested at Kirindy (a, b) and at Ranomafana (c, d)
