More than environmental control at local scales: do spatial processes play an important role in floristic variation in subtropical forests? Acta Botanica
Maçaneiro,João Paulo de; Oliveira,Laio Zimermann; Seubert,Rafaela Cristina; Eisenlohr,Pedro V.; Schorn,Lauri Amândio.
ABSTRACT The effect of environmental variables on the plant species distribution in the Atlantic Forest raises the interest of researchers, but few studies, mainly at local scales, analyzed the influence of spatial factors on the environment and species distribution. Linear models and spatial correlograms were used to evaluate whether environment and space may predict variations in species composition of trees and shrubs in a Subtropical Rainforest remnant. The study area was divided in 25 plots of 400 m², systematically distributed, where individuals with DBH ≥ 5 cm were measured. Elevation and slope were the most important predictors of the floristic variations, but space, generally neglected in researches on South American's vegetation, had a relevant...
