Description
Summary:This paper presents a study of plant communities developed in the Keller Peninsula, King George Island, Antarctica, during the austral summer of 2002/2003. Based on a systematic evaluation, on GPS referencing and on aerial photographic surveys of each plant community, we drew up a map with their distribution, followed by descriptions based mainly on their biodiversity, physiognomy and relationship to bird communities and ground configurations. In the studied area it was possible to differentiate 35 vegetal communities, which had been described being based mainly on the form of growth of the plants of the species most representative. Este trabalho apresenta os resultados do estudo das comunidades vegetais da Península Keller, Ilha Rei George, Shetland do Sul, Antártica, realizado durante o verão austral 2002/2003. Cada comunidade foi estudada baseando-se principalmente na biodiversidade e na fisionomia das populações e suas relações com as comunidades de aves. Para delimitar as comunidades foram utilizados dados de GPS. Na área estudada foi possível diferenciar 35 comunidades vegetais, que foram descritas baseando-se principalmente na forma de crescimento das plantas e pelas espécies mais representativas.
