Search for: [Description = "The reportoire of airborne and substrate\-borne communications id described for two species of mole\-voles\: Microtus \(Terricola\) gerbei \(de Sélys\-Longchamps, 1847\) and M. \(T.\) duodecimcostatus \(de Sélys\-Longchamps, 1839\). The bahavioural significance of the different types of sounds emitted was analysed from observations of intraspecific interactions in captive environments. Substrate\-borne signals were used more often by dominant individuals, and were predominantly recorded in the more aggressive species, M. duodecimcostatus. The use of substrate\-borne signals is much more prevalent in the more aggressive M. duodecimcostatus, while the less aggressive M. gerbei has a larger acoustical repertoire."]
