Acomys

Heterospecific chemical signalling appears in studies of the temporal segregation of closely related species. Odour exposure was most effective in the taxon with labile features to its activity rhythm. Friedman et al. (1997) found such interactions in Golden Spiny mice (Acomys russatus). Exposure to odours from A. cahirinus, a co-existing sympatric, forced A. russatus to be active at less preferred times. Food niche specialisation, as well as differential activity rhythms, apply to co-existing species with narrow (plant) preferences (Petter and Peyrieras, 1970). All three species of Bamboo lemur (Hapalemur) overlap in selection of their...

Spiny mice, Acomys cahirinus, use all senses interchangeably in locating prey (Langley, 1988). These are cases of adaptive redundancy at the level of the sensory modalities. As is well known, deaf-blind humans use smell and taste more.
