Research output: Contribution to journalArticlepeer-review


Seventeen species of bats of Venezuelan highland forest, pertaining to three families (Phyllostomidae, Mormoopidae, and Vespertilionidae) were considered for genome size (g.s.) evaluation. Feulgen stained lymphocytes were microdensitometrically evaluated from two blood smears for each individual. The g.s. we got range from 4.5 pg for Lonchorhina aurita (Phyllostominae, Phyllostomidae) to 5.9 pg for Carollia perspicillata (Carollinae, Phyllostomidae). These values are among the lowest for homeothermic vertebrates, and agree with the reported values for paleoarctic bats. The possible function and evolutionary role were briefly discussed.
