Palm community transitions along a topographic gradient from floodplain to terra firme in the eastern Amazon

Abstract: Palms show clear niche segregation patterns along topographic gradients in tropical forests, with some species associated to terra firme and others to seasonally flooded areas. The aim of this study was to quantitatively describe the fine-scale spatial variation within a palm community, tracking the changes in species' abundance along environmental gradients associated with a perennial stream the eastern Amazon. The study of palm communities was based on 60 forest plots in which all adult palms were counted. W… Show more

“…Environmental factors such as soil characteristics, inundation, and light availability have a direct influence on the survival and regeneration of Attalea. The Attalea genus is known to be present at a nutrient, alkalinity, soil texture, and inundation gradient (Grégoire, 2010;Salm, Prates, Simoes, & Feder, 2015). Attalea occurs on dry to seasonally flooded soils; therefore, this species can be expected close to seasonally inundated areas (Moraes & Zenteno-Ruiz, 2017).…”

“…According to Salm et al (2015) the A. maripa show low tolerance to floods, obtaining a greater affinity for dry land, fact that may have influenced the greater emission of male inflorescences in this research.…”

“…These six explanatory variables were selected, based on findings from previous studies (Terborgh and Andresen, 1998;de Castilho et 180 al., 2006;Poulsen et al, 2006;Costa et al, 2009;Eiserhardt et al, 2011;Göldel et al, 2015;Salm et al, 2015). Topographic variables were selected to represent the form and shape of land surface: slope, aspect and terrain ruggedness.…”
