| helminths of six species of anolis lizards (polychrotidae) from hispaniola, west indies. | from hispaniola, an island in the west indies, 6 species of anoles, anolis cristatellus, anolis etheridgei, anolis eugenegrahami, anolis hendersoni, anolis monticola, and anolis olssoni were examined for helminths. helminths representing 2 species of trematodes, mesocoelium monas and urotrema scabridum; 1 species of cestode, oochoristica maccoyi; 11 species of nematodes, atractis scelopori, oswaldocruzia lenteixeirai, parapharyngodon cubensis, skrjabinoptera leiocephalorum, trichospirura teixeir ... | 1998 | 9920335 |
| fission in the evolution of a lizard karyotype. | the lizard anolis monticola has a diploid chromosome number of 48 (24 macrochromosomes and 24 micrcchromosomes). more primitive members of the genus, as determined by bone morphology, have 12 macrochromosomes and 24 microchromosomes. since the higher chromosome number is the derived condition, this is a case of karyotypic change by centric fission. | 1972 | 5049305 |
