چکیده
Eisenberg, J. F., and Edwin Gould. The Tenrecs: A Study in Mammalian Behavior and Evolution. Smithsonian Contributions to Zoology, 27: 1-137. 1970.—Tenrecs are found only on the island of Madagascar. The biology of the Tenrecidae is described by field and laboratory studies that focused on comparisons of social behavior and communication in several species. Detailed observations on the behavior of Echinops, Setifcr, Tenrec, Hemicentetes, and Microgale are related to ecological adaptations of each genus. Experimental manipulations of Hemicentetes revealed that a sound-producing organ composed of dorsal quills functions to coordinate the movements of mother and infants. Evolutionary trends in structure and behavior of the tenrecs are discussed. The mammalian feeding niches of Panama and Madagascar are compared. J. F.
