English abstract This study assessed the diversity of trees in six islands of Paraguay River, between Caceres and Taim„ Ecological Station in Pantanal, Brazil. These islands originated from two geomorphologic processes: meander neck rupture and sedimentation, which were compared. A Canonical Correspondence Analysis and a Cluster and Discriminant Analysis were used to determine the correlations between the abundance of tree species and the variables of soil attributes (chemical and textural properties). Geo-technologies such as remote sensing imagery and GPS were important tools used during this work. The group formed by the most frequent and abundant species in the islands Sapium obovatum , Psidium nutans and Laetia americana was positively correlated with soil properties that presented high values in the islands, such as magnesium and saturation of magnesium, aluminum, clay and silt
Portuguese abstract Este estudo avaliou a diversidade da vegetaÁ„o arbÛrea em seis ilhas do rio Paraguai, entre C·ceres e a EstaÁ„o EcolÛgica de Taiam„, Pantanal Matogrossense. Foram comparadas ilhas formadas por dois processos geomorfolÛgicos: a partir do rompimento do colo do meandro do canal e de sedimentaÁ„o. An·lise de CorrespondÍncia CanÙnica, An·lise de Cluster e Discriminante foram utilizadas para verificar as correlaÁıes entre a abundancia das espÈcies arbÛreas e as vari·veis dos atributos do solo (propriedades quÌmicas e texturais). Geotecnologias como imagens de sensoriamento remoto e GPS foram ferramentas importantes na execuÁ„o deste trabalho. O grupo formado pelas espÈcies mais freq ̧entes e abundantes nas ilhas: Sapium obovatum , Psidium nutans e Laetia americana , correlacionou positivamente com atributos do solo que nas ilhas apresentaram altos valores, como magnÈsio e saturaÁ„o por magnÈsio, alumÌnio troc·vel, argila e silte
