However, a number of other authors have noted the absence of edge effects in tropical dry vegetation formations: Sampaio and Scariot (2011) did not find any differences between the forest edge and interior in relation to the composition and abundance of seedling and adult individuals in a fragment of dry forests subjected to the same type of climate as the present study; Oliveira et al.
