Estudios citogenéticos en tres especies de aves antárticas
Peripheral blood samples from Phalacrocorax bransfieldensis (7 males), Larus dominicanus (4 males- 5 females) and from Chionis alba (6 males-5females) were taken during the Antarctic expeditions of ‘97-‘98 and ‘98-‘99 summers in the Jubany Station and Orkney Station respectively. To obtain of mitoti...

| description | Peripheral blood samples from Phalacrocorax bransfieldensis (7 males), Larus dominicanus (4 males- 5 females) and from Chionis alba (6 males-5females) were taken during the Antarctic expeditions of ‘97-‘98 and ‘98-‘99 summers in the Jubany Station and Orkney Station respectively. To obtain of mitotic metaphases long time cultures of lymphocytes were made. P. bransfieldensis, 2n=72, L. dominicanus, 2n=68, C. alba, 2n=76. Although the present work constitutes the first description of the number and the chromosome morphology of these three species, it is still necessary to make more studies with different types of differentials staining, like C and G bands, that allows to understand in the future the mechanisms that happend during the course of their evolution. |

Muestras de sangre periférica de Phalacrocorax bransfieldensis (7 machos), Larus dominicanus (4 machos - 5 hembras) y Chionis alba (6 machos - 5 hembras) fueron tomadas durante las campañas antárticas de verano ‘97-’98 y ‘98-’99 en las Bases Jubany y Orcadas, respectivamente. Las metafases mitóticas se obtuvieron de cultivos de linfocitos de larga duración. P. bransfieldensis, 2n=72, L. dominicanus, 2n=68, C. alba, 2n=76. Si bien el presente trabajo constituye la primera descripción del número y la morfología cromosómica de estas tres especies, aun es necesario realizar estudios con distintos tipos de coloraciones diferenciales, como los bandeos C y G, que permitan en el futuro comprender mejor los mecanismos que sucedieron durante el transcurso de su evolución.
