Abstract: Durante la Tercera Expedición Ecuatoriana a la Antártica (1991), se dió inicio al proyecto "Cianobacterias fijadoras de nitrógeno en Punta Fort William, Isla Greenwich, Shetland del Sur". Muestras de musgos, líquenes, rocas y un suelo endurecido de aspecto costroso fueron recolectadas y examinadas en busca de cianobacterias. Abundantes cianobacterias filamentosas de la familia Oscillatoriaceae fueron detectadas tanto en el suelo como asociadas a musgos Polytrichum juniperus Hedw. y Polytrichum sp. Especímines del Nostoc sp. de la familia Nostocaceae, se encontraron en los cefalodios del líquen Stereocaulon alpinum Laur.
During the Third Ecuadorian Antarctic Expedition (1991), the project "Nitrogen-fixing cyanobacteria at Point Fort William, Greenwich Island, South Shetland" was started. Samples of mosses, lichens, rocks, as well as samples of crusty soil, were collected and studied in search of cyanobacteria. Abundant filamentous cyanobacteria of the family Oscillatiriaceae were detected in the crusty soil and in association with the mosses Polytrichum juniperus Hedw. and Polytrichum sp. Especimens of Nostoc sp. were foundin the cephalodia of the lichen Stereocaulon alpinum Laur.
