Abstract

The connected fragments of submontane and alluvial deciduous forests are present along the topographic gradient with large pedological and geomorphological variations. In order to understand the variations of ecological guilds and geographical contingent of forest community in a watershed, 200 plots of 100 m² divided into 40 sampling points with five plots each were distributed from the headwaters to the floodplain of the Jacuí River. In each sampling unit were identified and measured all woody plants with diameter at breast height ≥ 5 cm. From the total sample was performed a cluster analysis of floristic similarity, resulting in three forest communities. These were termed formation, submontane and alluvial, and the area dominated by both formations.For the total sample and the groups was determined the percentage contribution of species and individuals, by classification of ecological guilds of dispersal of seeds and regeneration and geographic quotas. The geographic contingent composition of forest communities was dominated by species of wide distribution. The patterns of ecological guilds were different between groups. However, all groups revealed higher contribution of zoocoric species.
