Resumo(s)
Little information is available on the patterns of genetic connectivity in owls. We
studied the genetic structure of the eagle owl Bubo bubo (Linnaeus, 1758) in southeastern Spain at two
different spatial scales. Seven microsatellites previously described for this species were used, although
only six loci amplified correctly. The observed low genetic variation could be explained by the short
dispersal distance, high mortality rate and high degree of monogamy shown by this large nocturnal
predator. As expected, the highest genetic isolation was detected in the geographically most isolated
population. Significant genetic differentiation was found among study units separated by less than
50 km. The territorial analysis showed interesting connectivity patterns related with the gene flow and
turnover rate of the breeding individuals. The lowest genetic diversity was found in the region with the
largest population, which could imply incipient inbreeding.
