โœฆ Synopsis

Buoyant density in CsCI, melting temperature, and G รท C base content of the DNA from four species of Akodon (Rodentia, Cricetidae) were determined. The buoyant density values of 1.699-1. 701 g/cm 3 were in accordance with the data reported for other cricetids. No satellite bands were seen in neutral CsCl. The Tm values determined in 1 x SSC ranged from 86.2 to 87.0 C, which corresponds to G+ C contents of 41.~43.2ยฐ//o. There was good agreement in DNA base composition of the four species, although values were slightly higher in A. obscurus, suggesting a certain degree of interspecies variability.

Genetic similarity between species of rodents of the Akodon genus (A. dolores, A. molinae, and A. azarae) has been estimated by analysis of electrophoretic zymograms corresponding to 23 loci. Nei's coefficient between A. dolores and A. molinae was within the range usually found in conspecific popula
