Resumen

MORAES, N.; MORGANTE, J. S.  y  MIYAKI, C. Y.. Genetic diversity in different populations of sloths assessed by DNA fingerprinting. Braz. J. Biol. [online]. 2002, vol.62, n.3, pp. 503-508. ISSN 1519-6984.  http://dx.doi.org/10.1590/S1519-69842002000300015.

In this study we analyzed a population of Bradypus torquatus with individuals originally distributed in different localities of Bahia, and two populations of B. variegatus with individuals from Bahia and São Paulo States. Using the DNA fingerprinting method, we assessed the genetic variability within and between populations. Analysis of the DNA profiles revealed genetic similarity indices ranging from 0.34 ± 0.07 to 0.87 ± 0.04. Similar low levels of genetic variability were found only in isolated mammalian populations or among related individuals. This study presents the first analyses of genetic diversity in sloth populations.

Palabras llave : Bradypus; DNA fingerprinting; genetic variability.
