Influence of plot size on distribution analyses and effects of altitude on spatial patterns of palm heart in Submontane Tropical Rainforest, Ibirama, Brazil

The knowledge about the behavior of the species and its analysis is very important in order to support management and conservation techniques. Therefore, the aims of this study were to analyze spatial distribution of palm heart (Euterpe edulis) and verify the influence of altitude on spatial distrib...
