Primate Serenades: Call Variation, Species Diversity, and Adaptation in Nocturnal Strepsirhines

摘要: Interspecific divergence in acoustic signaling systems is a major focus of biodiversity and evolutionary research, but empirical data for primates are rare. Our research team compared communication calls four cryptic, genetically defined mouse lemur (Microcebus) species uttered comparable social situations. We found that vary interspecifically to different extents depending on the context. The pattern given startle context was conserved across species, whereas agonistic mating contexts showed significant interspecific variation. Uniformity can be explained by similar physiological environmental constraints; divergences have been several hypotheses including natural sexual selection. Because remarkable species-specific differences frequency contours, advertisement most useful diagnostic tools noninvasive subspecies identification.
